Audio CD: A true audio CD can be at most 79 minutes in total play time. If your recordings are more minutes than that, either break them down into multiple disc sets or modify your project and make it a Data CD. A Data CD is not limited by total play time. It's limited by file size only. For example, a Data CD of .mp3 files can play for hours in a computer, some car cd players, some game systems and some bluray or DVD players. The drawback is that a data cd is not going to play in an older CD player. A Data cd of mp3 or wav files can easily be imported into iTunes from your computer for example.
In any case: You should try to make your discs 74 minutes or less to be compatible with most cd players. The problem is that some audio files can be burned to high capacity discs like ours, but the last track or the last part of a track might not fully play in all cd players. To be most compatible, try to keep it under 74 minutes. If we try to burn your audio cd and our system gives us an 'insufficient space' error, we'll have to inactivate the project and you'll have to edit down and shorten the disc, or add a 2nd disc to the set (split it up into another disc).
When you make your .WAV or .MP3 files, they must be in exactly this format (there are no ranges or options). Then, add them to the zip file in alphabetical order (we recommend you name your files with leading zeroes such as 01aaa.mp3, 02bbb.mp3, 10ddd.mp3, 11eee.mp3 so they sort properly).
Audio CD players read in this format, thus you need to have your .wav or mp3 files in this format:
Audio Sample Rate: 16bit
Channels: 2 (stereo)
Audio Sample Rate: 44 khz
Bit Rate: 1411 kbps (does not matter for .mp3, but we recommend 192 or higher)
Most newer dvd players, game systems (xbox, ps3), cd players, bluray players, car cd players can read mp3 data cds as audio. You can get hours of audio on an mp3 data cd.
