Studio Documentation

If there is something about the new WSUM Studios which needs clarification for better operation, please feel free to CONTACT the WSUM Techs and ask. We will endeavor to provide you with any information you require to execute your on-air performance in the manner you best see fit. The options, capacities, and potential available to you and your performance is immense. Please don't hesitate to ask. It is important to share information as things are not at peak operating parameters. Don't hesitate to CONTACT the techs when you experience any equipment or facility failure. The sooner we know, the better. Don't forget, EXT1 on the consoles is a real world radio listen to your performance, post-delay. Don't miss the chance to hear yourself and check for problems.

Equipment

If there is a piece of equipment which could use a little more documentation, please feel free to CONTACT the WSUM techs.

Recording your session

Record Button
All studios at WSUM are capable of recording your performance, including the Main Studio. While there is an archive process established for recording every hour of broadcast from WSUM, it may suit your needs to make a recording of your show on your own. Knowing the steps needed to record in any studio will provide a more versatile audio file than our on-air archive provides. The on-air archive is primarily a record of what goes out to the broadcast, thus it has the following conditions which may make it less desirable than making your own recording:
  • The on-air archive only records from the studio currently set to the live broadcast; typically the main studio.
  • The archive records at 96kbps .mp3 which is a highly compressed file.
  • The archive will record any interruption to your programming originating from the Emergency Alert System.
  • The archive has additional processing enabled on the audio to tailor the audio for the FM transmission. If the intent is to preserve the performance, this processing may affect the final quality of the recording.
All studios have a "host computer" dedicated to that studio which automatically receives signal from the console as well as providing and input to the console on the computer fader. Every one of these computers also has a copy of Adobe Audition installed on it for the purpose of working with audio files. While it is not necessary to use Adobe Audition, it is the program used by most at WSUM for this purpose.

Axia Studios

Axia Record Arm

To send audio from any of the Axia consoles [Main Studio, Production Studio, or News Booth] it is necessary to arm the tracks you wish to record. This is done by sending each source you wish to record to Program 4 or the record bus. This will need to be done for all board channels which you wish to record with the default record channel on the host computer.

  • If you do not have any faders with "Program 4" selected, you will NOT get audio in Audition's default channel.
  • The FM and webstream broadcast is ALWAYS "Program 1."

If you wish to send particular audio to WSUM broadcast and stream, but not record it in your own recording, do not arm that channel! It is always easy to remove silence from your recording later in Audition, or as the addage goes, "Fix it in Post!"

Update:  There are now multiple channels of audio coming from the console into the host computers.  In the audio control panel in Windows, one will see as many as 8 stereo channels of audio arriving at the host computer labeled as "Axia Wave 01, Axia Wave 02, etc..."   The default channels as they arrive at the computer from the console are as follows:

  • Axia Wave 01 = Program 1 (ALWAYS THE FM BROADCAST AND WEBSTREAM IN THE MAIN STUDIO!!!!)
  • Axia Wave 02 = Program 2
  • Axia Wave 03 = Program 3
  • Axia Wave 04 = Program 4 (Default Record Channel)
  • Axia Wave 05 = Aux A
  • Axia Wave 06 = Aux B
  • Axia Wave 07 = Aux C
  • Axia Wave 08 = Aux D

In order to assign audio to the aux channels on the Axia consoles, select the OPTIONS button on the channel you want to send, then on the right hand side of the mixer, press the AUX SENDS button.  The control knobs for each option are at on the back riser of the console.  Note that the knobs can also be pressed as a button to select the channel feed as PRE (fader position does not affect the level of the channel to the feed) or  POST (fader position on the console is used in the feed to AUX.) Pre is useful for re-editing levels and fades on sources after the show in order to tweak the final show or for feeding into effects units.

Listen Rooms

Milennium Console
The listening rooms are also capable of recording all work done on the console. There is no record track arming necessary as the Program output of the consoles is automatically sent to the computer and recorders.

Recording from the Internet

If content from the Internet is to be used in your production, it is a good habit to capture the audio to file in advance of your show. The Internet and campus networks are great, but not infallible. Thus, having the audio on hand locally can be an advantage.

In WSUM's studios, the easiest way to record incoming computer audio is to assign the computer fader to the record bus (program 4 or just program in the listening rooms). This obviously will not work on all of the other computers since they do not have mixers.  Outside the studios, the computers do not normally include outbound audio with the inbound audio. It is possible, however, on most computers to do exactly this.

To assign the computer's outbound audio to the incoming audio, do the following:

  • Under the Control Panel, select "Sounds and Audio Devices"
  • Select the "Audio" tab.  Press the "Volume" button under Sound Recording
  • Before anything is changed here, please check to see what is currently selected.  This is so you can set this back when you are done which is super important.
  • Select the checkbox under "Stereo Mix" (or it may say "Playback") and make sure the volume fader is maxed up.
  • Leave the volume window open so that you can set this back when you are done.

Now open Adobe Audition or your record app.  Press record and you should be getting audio from all applications running on the computer, including the Internet.   Note that when using Edit Mode in Adobe Audition, pressing F10 will turn on Audition's audio meters without having to record a file.  This is a great way to see if you are getting good audio.  Also, pressing Alt-X and Alt-Z (or using the Options -> Metering Menu) will respectivly turn on phase and frequency (EQ) analyzers.  I find both of these tools to be very handy.

When you are done recording, please set the Sound Recording input back to where it was.  In the WSUM news-room, this must be set back to Rear Input to enable the phone recorders.

Axia Consoles

WSUM's digital broadcast system is a digital Axia Audio system with all audio being routed on the WSUM network backbone. The main consoles are known as Elements and are feature rich. Axia has put together an Element Operator's Training Guide if you would like to master the system. Contained within these pages will be the basics of getting started with the WSUM studio mixers.

End Show button

Each of the Axia consoles has a red "End Show" button on the control panel.  This button will reset the console to it's default settings.  Note that using this button will never interrupt a source in use.  If the default assignment for a channel in use is different that what it is currently doing, the channel will wait until it is turned of to make it's change back to a default state.

It is also a good habit to reset the board back to it's default settings before your show as well in the event the knucklehead before you did not do so.  Also, whenever the board is exhibiting odd behavior, it is a good idea to try this reset first.

You are encouraged to play with and adjust the broadcast console as you see fit.  It is very difficult to do somehting that cannot be fixed with the "End Show" button.  There are many features that can be adjusted like inputs, EQ's, compression and such, so if there is somehting that you think will make your show sound better, try it in the Production Studio and if it works use it in the Main Studio.  Just don't forget to reset the board when you are done!

Guest Metering

Guest Metering

Sometimes when there is a studio full of people talking on all of the mics at once, it can be difficult to follow who is talking on what mic and when.  The Axia element mixer consoles have an additional metering page that can be used to monitor each of the microphones individually. 

To activate the extra meters;

  1. Press the Meter Options button
  2. Press the F6 knob.  It is on the riser at the back of the console, or the control that is all the way on the left and towards the back of the mixer.  Note that this is a knob that also works as a button.

To exit out of the meter page and back to the clock display, press the Meter Options button twice.

Host Computer paths

Every studio at WSUM has a computer dedicated to that particular studio.  These computers are connected to their particular studios not with audio cables but instead over the computer network.  This allows for some really cool functionality with the host computer that one cannot get by plugging in a laptop.

Each host computer has a muti-channel software driver that connects to the WSUM broadcast plant multiple times.  The result is that when one looks at the "Sound and Audio Devices" control panel in Windows, multiple audio devices appear.  Since these drivers are ASIO capable, they can be used with many different applications, including the default Adobe Audition that is installed on each of these computers.

These audio devices, or "channels" have different names and default settings which will allow for everything from recording one's broadcast session to using software to manipulate audio real-time for effects.  The channels can also be used for both recording and playback all at the same time. 

In the big studios at WSUM, the default settings are eight stereo channels in and out of the the host computer.  The outputs from the computer to the mixer each show up as seperate channels which can be used on seperate faders.  The first two of these faders show up on the default profile, but anything above that needs to be manually assigned to a fader.  To do that, select options on a fader that has a source that you will not be using, then select the source button on the top right section of the audio console. The inputs to the host computer from the consoles default to the standard outputs from the console.  Here is a chart of the host computer outputs:

Windows Device Name Adobe Audititon Name Axia Console Source Name
Host computer outputs
Axia Wave 01 (default output device) Livewire 01S Computer
Axia Wave 02 Livewire 02S comp 02
Axia Wave 03 Livewire 03S comp 03
Axia Wave 04 Livewire 04S comp 04
Axia Wave 05 Livewire 05S comp 05
Axia Wave 06 Livewire 06S comp 06
Axia Wave 07 Livewire 07S comp 07
Axia Wave 08 Livewire 08S comp 08

Each of the three studios that has these outputs set up already has desktop links to open up VLC media player to use their respective channel output.

The default settings for console audio outputs coming back to the host computer are preset to allow recording from any of the output busses on the Axia consoles.  This makes it possible to record your session in any way that you see fit.  Specific recording instuctions can be found in the Recording Your Session section of this documentation.  Remember that the default record bus on the host computer is Program 4 which specifically needs to be armed to record.  Here is the chart of console outputs back to the host computer:

Axia Console Output Bus Windows Device Name Adobe Audition Name
Host computer inputs
Program 1 (ALWAYS Broadcast Chain) Axia Wave 01 Livewire 01S
Program 2 Axia Wave 02 Livewire 02S
Program 3 Axia Wave 03 Livewire 03S
Program 4 (default Windows record device) Axia Wave 04 Livewire 04S
Aux A send Axia Wave 05 Livewire 05S
Aux B send Axia Wave 06 Livewire 06S
Aux C send Axia Wave 07 Livewire 07S
Aux D send Axia Wave 08 Livewire 08S

Note that when using Adobe Audition, there are some specific things to remember:

  • Sessions should always be opened with a samplerate of 48000 as this is the native samplerate of the WSUM broadcast plant
  • An input or output with an "M" instead of a "S" [IE, Livewire 01M] is a mono source and defaults to the left channel.  If just a vocal is to be recorded to a particular track, use the "M" source instead as it will save space and make smaller files.
  • It is indeed possible to use the effects in Adobe Audition "real-time" to modify a particular sound coming throgh the mixer for a live show.  It takes some special settings to do so, so please contact MattRock for info on doing this.

PLEASE NOTE: Please feel free to modify the console settings to your own needs, but have the respect to reset the board when you are done with the "End Show" button after you are done.

Telephone Calls and the broadcast

WSUM uses a device known as a hybrid codec in order to be able to connect telephone calls to the program. This hybrid, or NX12 does a great job of both making telephone connections sound good and easy to do. With the NX12 hybrid, there is no need to use a handset at all for setting up a caller or making a call. Everything needed to work with the telephone system can be done with the Element Console.

Here is a sample of what the screen will look like when a call is being received by the Element console.

Note that the scribble icon (the graphic above the scribble strip on the fader channel that normally shows the channel number) shows a ring graphic to help you find the fader that is ringing.

Receiving Calls

When a studio line rings, the Element console will automatically see that inbound call and try to get your attention. The first thing the console will do is flash a red box on the status monitor with the phone number of the line ringing as well as the caller ID of the caller coming in. The console will also show a ring icon on the scribble strip at the top of the fader which is connected to the inbound call.

Answer call with console, but NO BROADCAST

On the fader that is ringing, press and hold the TALKBACK button, and then press the PREVIEW button, both on the fader which is ringing. This will answer the call and AUTOMATICALLY turn on the host microphone so that you can speak to the caller. You do not have to turn on the host mic fader to speak to the caller. In fact, you will notice the graphic above the host mic scribble strip change to show that the mic is in talkback mode. Optionally you can just press the PREVIEW button to answer the call, but then you will need to press and hold the TALKBACK button to speak to the caller. Note that if the preview speakers are turned up, you may get a bit of an echo. Put headphones on and turn the speakers down to get around this. When you are done setting the caller up, you can either release them (hang up) by pressing PREVIEW, or you can put the caller on hold by pressing the HOLD button (it is then safe to turn off the preview by pressing the PREVIEW button again). Note the icon box above the scribble strip when the caller is on hold.

Answer call ON THE AIR

When you are ready to put a preview, hold, or ringing caller On The Air, just turn the channel ON like normal and the call will behave as a normal source. Note that there is no automatic talkback at this time. If the caller is on the air, you need your mic on to speak to them. Pressing the OFF button will then hang up the line.

Placing Calls

All functions for placing calls are the same as receiving calls. If the scribble icon shows one dot, the line is ready to make a call. To do this, press and hold TALKBACK, press PREVIEW and release, or turn the channel on and you should get a dial tone. Once you can hear the dial tone, use the keypad on the right hand side of the element console to dial the phone number as if you were using a normal telephone.

DJ Workstation

DJ Artwork
Wikipedia defines Turntablism as the art of manipulating sounds and creating music using phonograph turntables and a DJ mixer. Many WSUM hosts throughout the years have turned to the turntables to create their program. This has resulted in the inclusion of the "DJ Station" in WSUM's Main Studio. The DJ Station consists of a Rane TTM57 DJ mixer connected to a dedicated computer running Serato's Scratch Live software. These two components together form a basic turntablist rig and connect to the broadcast mixer via a sidecar mixer located on the DJ table. This rig can be used 100% analog with vinyl, 100% digital with it's own computer or your laptop if you prefer, or any combination between. The primary advantage to DJ'ing 'a la turntablist' style is to gain the use of a crossfader, or one single left to right fader to mix between two sources. When music is cued up properly, the crossfader allows a transition from source a to source b without dropping the beat. Without going into the history of turntablism, scratching is the means by which a record is cued up to match what is currently playing. DJ mixers will always allow for cuing in headphones separate from the program to this end. Ever see a DJ with one half of his headphones to his ear? Recent years has seen a lot of advances in both hardware and software to make turntablism accessable without having to haul around a big crate of vinyl. Scratch Live in combination with the proper mixer allows for all source music to be used to come off of a portable hard drive or USB thumb drive. The digital media is then processed in the software to provide a visual representation of your audio to assist in beat matching and then offers control of playback via turntables or CD players with special "control" media. In other words, a special record becomes the tool used to play .mp3's (or other file types). If you think you may be interested in using the DJ workstation for your show, please read on.

Rane TTM57SL Mixer

TTM57SL
The Rane TTM57SL mixer is the Serato enabled mixer used at WSUM in the Main Studio. The mixer has two input channels, one for each side of the cross-fader. Each of these input channels can be set to accept input from one of four sources. Currently, the mixer has a one Technics SL-1210M5G Pro Turntable and one Denon S-1200 turntablist CD player dedicated to each channel. Each channel can also be selected to take input from one of two channels of audio coming from the computer. While it is possible to use any media player to play to the digital channels, Serato Scratch Live provides the advantage of using two separate decks at the same time. The input select knob at the top of the mixer determines which input is active on each channel respectively.
  • A1-Left Turntable
  • A2-Left CD player
  • A3-Right Turntable
  • A4-Right CD player
  • D1-Left computer deck
  • D2-Right computer deck
The OUTPUT of the TTM57 mixer routes directly into WSUM's broadcast network and is controlled by both the output level on the Rane Mixer and the fader on the Axia sidecar mixer. Both of the faders must be turned up to get audio and the Axia channel must be turned on to get audio. This does not apply to headphones connected to the Rane mixer. The headphone level controls are on the Rane mixer only. Additionally, the mic on the boom arm is controlled by the Axia sidecar mixer and not the Rane mixer. This allows for the cleanest audio possible from the microphone for the broadcast. Additional documentation, manuals, and control features of the Rane mixer can be found on the Rane website.

Serato Scratch Live

Serato Scratch Live egg
Scratch Live is a turntablist software made by Serato and is currently one of the more popular software tools for DJ mixing. Serato provides the following tasks for a user who would like to use digital media for mixing:
  • Two playback decks for each side of the mixer crossfader
  • Digital "crates" for preparation of music on external hard and thumb drives
  • Visual representation of the audio to help find downbeats
  • Vinyl or CD control via Control Vinyl or control CD's
  • More features listed on http://scratchlive.net/

IP Mixer

Telos Zephyr IP Mixer
The IP mixer can be used to connect audio to the WSUM studios over the Internet. Once connected, the IP mixer can also provide a chatter channel for communication between the field and studio without going to broadcast. In order to control audio routing at the studio from the field, it will be necessary to install a WSUM remote panel on your computer, or make sure the panel is set before the mixer is checked out. Please follow the instructions here to install the necessary software to access the WSUM remote IP panel. Once the panel is installed, please select the correct button as to the usage of the mixer in the field. Once the mixer is connected to the Internet, press the [CONN] button on the mixer to establish a connection to WSUM Studios. In the event that the connect dialog on the mixer does not have the connection address for the studio, it is: tscp:WSUM-studio@UWisc

Notes on the live studio...

Turntables: Balancing a Tonearm

Technics SL-1200

There are many methods of configuration of the turntables, especially a turntable as popular as the Technics SL-1200. WSUM encourages hosts to do what they need to do to make their show sound as good as possible. Please read on for instructions on balancing the turntable tonearms.

If you modify the setup of the turntables or any equipment, it is expected that you will return the equipment to a standard setup when you are done.  Everyone deserves a consistent starting point from which to accommodate their needs.

If you plan on playing a lot of vinyl or scratching, please consider purchasing your own cartridge heads and styli.

Cartridge/Headshell Assembly

 

Headshell Assembly

Mount your cartridge with the screws supplied. Make sure it is parallel to the sides of the headshell.

Headshell weight positioning

An auxiliary weight may be necessary between the cartridge and headshell, mostly in a DJ application. Many new cartridges and new turntables come with these weights. If you cannot achieve the recommended tracking force, then this weight is what will be needed.

Installing the Cartridge Assembly

Installing a headshell assembly

Install the headshell/cartridge into the front of the tonearm, as shown. Turning the locking collar will hold the shell in place.

Tonearm Balancing

Counterweight Adjustment

With the tonearm locked in place, put the anti-skate dial on "0" and push the counterweight onto the rear of the tonearm. Make sure that the numbers face to the front of the turntable. Turn the weight until you feel it "click" into place.

Tonearm Positioning

Unlock the tonearm from the rest, and move it toward the middle, about one inch from the edge of the platter. Hold the arm off the surface with your right hand on the fingerlift. Begin turning the counterweight one way or the other, until the arm seems to just float.

Tonearm Balance

As seen in the picture, the arm, when properly floating, will not face up nor down, it will stay parallel with the platter. It may take a few tries to get this correct. Lock the tonearm back on it's rest.

Counterweight Adjustment

Counterweight Display Calibration Holding the rear, silver, section of the counterweight with one hand, use your other hand to turn just the number ring. It doesn't matter which direction you turn it, but you will want "0" to face up when you are done.
Counterweight Weight Adjustment

Using just one hand, turn the entire counterweight (the silver part) COUNTERCLOCKWISE until the recommended tracking force is achieved. New cartridges will tell what the ideal number is. As a rule of thumb, however, most "hifi" cartridges track between 1 and 2 grams, while most DJ cartridges track between 3 and 5 grams.

WSUM Cartridges

WSUM currently supplies Shure SC35C cartridges for general use. If you are looking for a different sound or are not willing to be subject to the habits of others who use the turntables, hosts are always welcome to install their own head shells and cartridges for their own use. Here are the general statistics and information on the SC35C cartridge and the SS35C stylus from Shure's website:

SC35C DJ Phono Needle, Standard - Scratch/Mix/Spin

Skip Resistance:

Anti-skate adjustment

anti-skate adjustment

Set the anti-skate dial to coincide with the tracking force. In other words, if the tracking force is 2 grams, set the anti-skate dial to "2". The exception is for DJ's who scratch and back-cue. Your anti-skate must be left on "0"

That's the whole procedure! This should be done every time the turntable is moved, transported or shipped. It is also a good habit to do this at the beginning of every shift for which you will be playing vinyl as the last time the turntables were used, they may have been adjusted to different taste. After a few tries, it will become a 10 second job, and will save your vinyl, your ears, and your sanity!

Media

As the caretaker of your media, I hope to convey how important it is to tag your media. Keep the minimum needed data to find your piece in file tags, and you will have a much easier time finding your piece when it is lost.

Adding Music to Digital Library

In order to add music to the music archive at WSUM, two steps must be completed:
  1. Rip the music from CD to file (or save the file)
  2. tag the music files with clean and proper metadata information
The process of ripping music from a CD to file can be done in two different ways; fast or slow. To achieve maximum quality, we will use the slow method. This method will be agressive in getting all music information off of the CD and into a file as possible, thus giving a file which will contain as much of the artist's expression as is possible for the CD to carry. The other question about ripping CD's is what file format to use. Since such a large portion of the existing library is already ripped in FLAC format, this is the recommended format. FLAC is a free codec which unlike MP3's will retain all of the original music information which was on the CD. All common media players like VLC, Winamp, and Foobar2000 will understand FLAC files already. After the files are ripped, they need to be tagged before they are added to the music library. There is a huge process of information that follows the tags in files placed in the music folder, therefore it is of the utmost importance to make sure all files added to the digital music library are clean and well tagged. In order to do this, all the music currently in the music folder has been tagged by a program called Picard Tagger. Picard Tagger is a program put forth by the community at http://musicbrainz.org/. MusicBrainz is a public domain, voluntary site that offers this intro: MusicBrainz is a community music metadatabase that attempts to create a comprehensive music information site. You can use the MusicBrainz data either by browsing this web site, or you can access the data from a client program — for example, a CD player program can use MusicBrainz to identify CDs and provide information about the CD, about the artist or about related information. You can also use the MusicBrainz Tagger to automatically identify and clean up the metadata tags in your digital music collections. Find out more in the introduction.

Ripping CD's

There are many programs which can be used to rip CD's. This guide will focus on using the free Exact Audio Copy program. This guide is based upon recommendations put forth by the community at Hydrogen Audio Forums. Specifically, this guide follows the EAC Lossless Backup page.

If EAC is already installed and ready to go, you are ready to get music from the CD into files on your computer. Insert a CD and the tracks should show up in the window as unknown.

Press the CD icon, and EAC should look up the CD @ CDDB. If not, this is the point where you will need to manually enter all of the track information.

Make sure CD title, artist, and tracks are all filled in before the rip begins. Once the info is set, press the "MP3" button to rip the CD to files. You will need to choose a folder to save the files. Use your P: drive to put the music in your own network folder.
Make sure you either have no or all tracks selected, or the rip will only rip the selected tracks.

If all has gone as it should, at this point, you should have a new folder labeled with artist-album in the location you selected. In this folder should be the .FLAC audio files for each track you selected or the whole CD. If you are not adding this music to the music library, you can stop here.

Tagging ripped music files

Before any media is added to the music folder, the files need to be properly tagged. This is incredibly important due to the fact that there are many automated steps down the line which could be accessing the ID3 tags in the files. Most important is the radio automation systems. If a mistake is made here, the information will likely be wrong for a long time to come. If the time is taken right now to get this information correct, the likelyhood of problems down the line is diminished exponentially. ALL media which has been added to the digital music library by the WSUM techs has undergone the following process.

If Picard Tagger is installed, you are now ready to index and save your ripped music into the music library. Launch the application, select the "Add Folder" button and find the ripped music you wish to add to the digital music library. This will load the files into MusicBrainz.

If the files are already tagged by CDDB or manual entry, pressing the "Cluster" button will organize all files by album.

The next step is to see if the music is represented on the MusicBrainz website. Click on the Album and press the Scan button.

At this point Picard is scanning the music files for a fingerprint to see if the files are in MusicBrainz. If the files are not found, a manual search can still be done by pressing the "Lookup" button. This will open the MusicBrainz website which will also have a green "tagger" button.

Pressing this tagger button will load the metadata for the selected album into Picard. Files can be dragged from the left side of Picard onto the correct song title on the right side. If this is all correct, you are ready to rewrite the tags and save the file to the music folder. Highlight the album title and press "Save." If your files turn green and get a checkmark, your done!

At this point, the files should have all of the ID3 tags corrected, album art should be added if it was in MusicBrainz, and the files should be moved out of your save location and now are in the M:\music folder. Take a look!

MusicBrainz Picard Settings

Here are the default settings for WSUM for MusicBrainz Picard. If these settings are all correct, it will be a very easy process to add files to the digital music library. Please pay special attention to the "file naming" options page as this is where a mistake can be difficult to fix.

Please CONTACT the tech director for login username and password for WSUM to enter in the general settings of MusicBrainz Picard.

Software

Contained in the following pages are references to the various pieces of software used at WSUM. Please contact tech if you find any issues or out of date information.

Adobe Audition

Adobe Audition is the software used most often at WSUM and combines three separate tools into one package:

  • Edit: used for changing and manipulating a single audio file
  • Multitrack: used to combine multiple files and sources into a single file
  • CD: used to author audio CD's

The single most important difference to remember between Edit and Multitrack is that Edit intends to change the original audio file where Multitrack does not change the source file. Multitrack instead makes requested changes in the final output, or render. It is possible to record your performance in either Edit or Multitrack mode. The choice of which tool to use is purely subjective, however, using Edit to record does require less steps and files than using Multitrack.

  1. It is very important to make sure Audition knows what you intend to record. Since WSUM computers are networked, you may need to follow these steps to make sure Audition drivers are set.
  2. If you are in the Main Studio, News Booth, or Production Studio, all of the channels [mic, CD1, etc...] you want to record must be armed. Do this pressing the "Program 4" button at the top of the fader to send that fader's audio to the computer or recorder. If you are in a Listen Room, no record-arm is necessary. The computer already gets the "Program" audio.

configuring audio hardware

If you do not get audio into Adobe Audition, you will need to check the Audio Hardware Configuration.

Audition Hardware Configuration
Under the EDIT menu, select Audio Hardware Setup...
Open the Control Panel sub menu and make sure Axia Wave01 is checked for both DirectSound Input and DirectSound Output.Select OK to exit the menu.
Make Sure [01S], not [01M] is selected for both Default Input and Default Output. Set this under both the EDIT VIEW tab and MULTITRACK VIEW tab.

Recording with Audition

Recording Audio
EDIT MODE, If for some reason your window does not look like the picture, use the Workspace: button on the top right of the screen to Reset Current Workspace.

It is necessary to open a file before a recording can be made. Either selecting FILE->New or Ctrl+N will open a new file.

  • Sample Rate = 48000 (note: 48000 is the samplerate of all audio in the WSUM plant)
  • Channels= mono for voice records and stereo for music records
  • Resolution = 16-bit [for compatability with WSUM systems]
Press the RED CIRCLE record button on the bottom left to start recording.

 

When you are done recording, please be sure to save the file in your network [P:] drive and not on the local machine. Local machines purge information saved to them, and your network folder is accessable from anywhere in the station.  

MULTITRACK MODE, Multitrack is used to combine multiple audio files into a single file. Multiple files or songs can be opened under the FILE tab and then dragged into the various tracks in order to combine the files into a single file. Multitrack also requires that a Session be created in order to contain all of the pieces used for the session.

To record straight to a track, arm the track by pressing the red R button and then proceed the same as the EDIT instructions above.
After your multitrack session is complete, save the session to your own folder on the P: drive. Then to get a usable audio file, select FILE->EXPORT->Audio Mixdown. This will render your session to a single file.  

Exact Audio Copy

Exact Audio Copy or EAC is a program used to make perfect rips of CD's to computer audio files.

Installing EAC

If you are installing EAC for the first time, the Wizard will ask some questions and configure the drive for you. Please be sure to select "I prefer to have accurate results" for the drives configured.

Continuing the install, you will be asked for "Encoder Selection." Choose FLAC.

Go ahead and enter an e-mail address to access CDDB. This will help in the final tagging of audio files.

Finally, select the Filename Configuration. This isn't super important other than to help keep files organized. Our process will rename the files again later.

Any configuration for AccurateRip can be set to your choice. It is a nice but unnecessary feature for what we will be doing. Once you are past this point, EAC should be installed.

EAC Settings

Here are all preferred settings for EAC.









Additional command-line options:

-8 -V -T "ARTIST=%a" -T "TITLE=%t" -T "ALBUM=%g" -T "DATE=%y" -T "TRACKNUMBER=%n" -T "GENRE=%m" -T "COMMENT=%e" %s -o %d

MusicBrainz Picard

MusicBrainz is a free publicly maintained web database about music releases. Using the MusicBrainz Picard software, one can clean and maintain ID3 tags and add album art to many types of audio files. http://musicbrainz.org/doc/Picard_Tagger

Installing MusicBrainz Picard

Download the installer for Picard from the MusicBrainz Website. It will be very helpful to download the "Cover Art Plugin" right away and install that as well. This plugin is nothing more than a .py [python] file that needs to be moved into the "C:\Program Files\MusicBrainz Picard\plugins" folder. The install process is all defaults.

Pathfinder Mini-WSUM Panel

INFO OUT OF DATE:: See MattRock for details...

Pathfinder Mini is a program used to deploy WSUM specific controls via a small control panel. This is the program used to create the meter panels on all of the WSUM computers. It is recommended that UW VPN software be installed and active before using the WSUM remote panel. This will secure traffic between your remote location and the studio. Installation:

  1. Make sure you have a Panel Name, UserName, and UserPassword from the WSUM techs for your usage.
  2. Download the install application (Windows only)
  3. Install the app, and use default settings. Make note of the install folder as a config file will need to be changed
  4. Navigate to the install folder open PFMiniConfig.txt in a text editor like Notepad and change the contents of the file to: PrimaryServerIP=144.92.245.143 PrimaryServerPort=5200 BackupServerIP=144.92.245.144 BackupServerPort=5200 PanelName={contact tech} UserName={contact tech} UserPassword={contact tech}
  5. Make sure UW VPN is connected and run Axia PathfinderPC/PathfinderMini

Skype

Skype is software that allows real-time conversation with others over the computer.  Basically it turns the computer into a phone.  Skype is installed on the computers at WSUM and allow for conversations to be had through the mixer boards.

Skype allows free conversations with other Skype users, or they offer pre-pay purchases to connect from Skype to land lines and cell phones.  In order to use Skype, you do need to register an account.  This can be done by running the software itself.  Once you have an account, it is as simple as any chat program.  Note though, that on computers not in the WSUM studios, a microphone connected to the computer will be required.

Skype in the big studios

One feature of using Skype in the Main, Production, or News studio is the ability to send the ring audio to an alternative board fader other than the Skype fader.

In order to be able to hear a Skype ring without the audio going out over broadcast, follow these steps:

  1. Select PROGRAM 2 in your monitor path.  This will switch your headphones and booth speakers to the Program 2 channel.
  2. In Skype settings, set Speakers to "Axia Wave01" and then set Ringing to "Axia Wave02."
  3. Turn on both the "COMPUTER" and "COMP 02" faders on the board.  Un-set the "COMP 02" fader from "Program 1."

Now you can hear Skype ring, but it will not get broadcast.

UW VPN software

The UW VPN software is used to connect to the UW network from a remote location. VPN may be needed to access various remote features of the station. UW NetID credentials will be needed to use this software. More information is available on the UW KnowledgeBase: http://kb.wisc.edu/helpdesk/search.php?q=vpn
