Audio Formats

The following links provide users with detailed information about the types of audio files and compression compatible with Fuse.

Plum recommends using the free Audacity application to record audio. Audacity is free and easy to use, but it also has in-depth tools and plugins for more advanced audio manipulation.

Supported Audio Formats

When deciding on the audio format for an application, keep in mind that the Fuse engine automatically runs the files through a compression ยต-law algorithm. This downsamples all files to 8-bit, 8kHz.

There are three audio formats for development that are always recommended:

  • 8 kHz, 16-bit, linear PCM WAV

  • 8 kHz, 8-bit, ยต-law WAV

  • 32 kbps, 16khz, MP3 (Note: Anything larger is unnecessary. Poorly recorded MP3 files might not work with Fuse.)

Important Note: All audio files must be recorded in mono, not stereo.
