Audio File Formats

Simian supports the playback of .wav, .mp3, and .mp2 file formats, but each type of audio file format has multiple options when to encoding. If the incorrect encoding options are checked, you may experiencing audio playback errors and problems.

Here is a list of the support file format encoding settings, in order of preference:

1 - .wav - Linear/Microsoft PCM wave at 44100 Hz, 16-bit, stereo or Mono
2 - .mp3 - Constant Bit Rate (CBR), 44100 Hz, 16-bit, stereo or mono, and a common kbps (128, 192, 256, or 320)
3 - .mp2 - .mp2 files are recognized and can be played back by Simian if you have a sound card that natively supports playback. The .mp2 codec is becoming obsolete as playback support is being phased out of newer generations of audio devices and no company is currently licensing or providing software decoder options to install on the Windows OS. It is recommended that .mp2 libraries get converted to one of the formats above before upgrading to a new computer with newer operating system and newer audio cards.

Supported file formats with unsupported encoding settings that can cause playback issues. Convert any files with these encoded settings to the supported encoding settings listed above.
.wav
- ADPCM or any other .wav that is not linear PCM or Microsoft PCM. ADPCM, though previously supported and recommended in Wavestation, is a 4-bit file that has playback issues on Windows 7 and later operating systems.
- 24-bit and 32-bit (float)
- any bit rate other than 44100 Hz, such as 22050, 32000, 48000 and 96000

.mp3
- Variable Bit Rate (VBR). Variable bit rates will have inaccurate reported lengths in BSI applications.
- 24-bit and 32-bit (float)
- any bit rate other than 44100 Hz, such as 22050, 32000, 48000 and 96000

The following audio formats are not supported or available for playback in Simian:
.wma
.aac
