Softimage supports WAV files that use MPEG-3 compression, but it does not support MPEG-3 (MP3) audio files. As well, Softimage does not support MPEG-1 compression or audio files having more than two channels or high-sample resolutions. This is because they use a different format than standard WAV compression methods and need to be treated specially.
Normally, WAV files use Pulse Code Modulation (PCM) as the compression scheme, but there are a variety of schemes that can be used. If you look at the File > Properties dialog box of the Windows' Sound Recorder application, you can see the different conversion schemes that can be used.
Additionally, an audio file that uses an irregular sample rate may fail play. Usual sample rates are 8 kHz, 11.025 kHz, 12 kHz, 16 kHz, 22.050 kHz, 24 kHz, 32 kHz, 44.1 kHz and 48 kHz. In the event of an unsupported sample rate, an error message appears.
