Splat is a programme to generate some audio data which you may call music. It’s written in Python to make it easy to use, and all the crucial processing parts are implemented in C for fast number crunshing. It’s distributed under the terms of the GNU LGPL v3 so you remain a free individual when you use it.
Splat is not a programme to generate live audio in real time, at least not at the moment. So it’s better suited to the studio than to the stage.
Here’s a very small Splat example which creates a beep 440Hz sound:
import splat
gen = splat.SineGenerator(splat.Fragment(), [splat.filters.linear_fade])
gen.run(440.0, 0.0, 1.0)
gen.frag.save("A440.wav")
You can find some splats as well as other music, software and electronics things on verdigris.mu as well as on SoundCloud. You can send your creations to info@verdigris.mu.
