Audio Format

The most common question we receive at CDman regarding audio masters is "What format should my audio master be on?"

If you wish to submit your own, final CD-R music master, it must be compatible with all players throughout the world. To test this, you simply have to test your music on old standard CD players, like your car or older home stereo system for example. If your master plays, you are OK to proceed to the factory for replication. Just be aware that most software these days will support a variety of file formats -so just think about compatibility. If you burn a series of WAV files then you need a computer or a special CD player to support the file format. CD Music technically uses: AIF (file format) - 16 bit, 44.1Khz sample rate, stereo. To be compatible, you want to test on old gear. Just be aware that some players have a hard time reading your discs so don't automatically think your file formats are wrong.

  • Use multiple machines to test CD-R or DVD-R master discs.
  • Do not test your one off (burned) disc on a new CD player that supports WAV , MP3 files unless you are distributing these file types.
  • If you burn computer files (files that won't play on older music CD players, you are technically classified as having a CD-ROM master in the factory, as opposed to a music master.
  • If you only have WAV files and would like to upload them to our server, CDman can then create a final audio master for you. For rates, please call us at 1-800-557-3347
  • Do NOT use CD-RW blanks. These are special re-writable discs that are NOT COMPATIBLE with glass mastering. 

iTunes, Toast, Windows media, EZ CD Creator Pro, all these software applications are capable of creating both CD-ROM (data files) as well as Red Book compatible (aif) audio discs, so be sure you are creating an audio master and not data files. Note that your disc must be finalized (single session - disc at once) mode and function completely. Use headphones and be sure to test your index points, fade ins and fade outs, listen for clicks, tics, and pops. Skip to the next track and check for 1st beat cut offs. All <source> masters are copied verbatim so test thoroughly!
