The 'Snack' sound extension adds commands for sound play/record and sound visualization, e.g. waveforms and spectrograms. It supports in-memory sound objects, file based audio, streaming audio, WAV, AU, AIFF, and MP3 file formats, synchronous and asynchronous playback. The visualization canvas item types update in real-time and can output PostScript. New commands and file formats can be added using the Snack C-API. 'Snack' was developered primarily for handling digital recordings of speech, but is just as useful for general audio. It has also successfully been applied to other one-dimensional signals.
