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

  • For details about the MP3 format:

  • For details about the WAV format:

  • More info on audio terminology:

  • More info about mu-law or (µ-law):

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.

Follow this link and select the proper operating system download Audacity:

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 µ-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, µ-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.
