Using Snack you can create powerful multi-platform audio applications with just a few lines of code. Snack has commands for basic sound handling, e.g. sound card and disk I/O. Snack also has primitives for sound visualization, e.g. waveforms and spectrograms. It was developed mainly to handle digital recordings of speech, but is just as useful for general audio. Snack has also successfully been applied to other one-dimensional signals. @ text @@
