Cryosleep generates changing noisewaves with a superimposed binaural brainwave. In contrast to many brainwave generators, the sound itself is nice to listen to and varies over time. Demonstrations and sample settings are included.
DTMF2NUM is a tool for decoding DTMF and MF tones from PCM wave files. It supports any type of wave file, automatic optimizations (DC bias adjust and normalization), and both WAV and raw PCM data.
Gtk Signal Generator. It lets you use your sound card as an audio signal generator.
Random Phase Generator
Random Phase Generator is a small program that generates random phase music.
Rytmo explores some ideas about automatic rhythm generation.
SBaGen generates binaural tones in real-time according to a 24-hour programmed sequence read from a file. It can also be used to play a sequence on demand, rather than according to the clock, or to write a WAV file for playing later.
Soundweave is a tool for generating an endlessly changing sound out of existing sound-files. It reads the soudfiles in a given directory, or a given individual soundfile, and writes its output to the soundcard and, optionally to a file on harddisk.
tonegen generates a sine wave on the sound card or standard out.
