About
This is a python/c framework for building and manipulating sound processing pipelines.
It is designed for real-time control.
It includes objects for oscillators, filters, file-io, soundcard and memory operations.
It is low-level: every byte counts.
Currently works on Linux and OSX.
Tutorial
This is a brief tutorial covering the essentials of the python API.

History
Work on this version began late in 2001.
It was initially intended to be a robust sound engine
for my game prototype Axis Runner,
but it quickly grew out of control.
I have used this code for real-time performance
and also studio-time compositions.
The core has barely changed in the last 12 months; it works, it's tough.
Music
Here are two excerpts from work I have done using this software.
The River (introduction)(945K)
This is from an improvisation.
I used the Linear task, acoustic feedback with DspRdWr,
/dev/midi from a keyboard and a simple (230 line) looping script.
All on a P133.
Happy (introduction)(819K)
This was improvised on an acoustic piano, and then I used fast fourier transform (libfftw, not implemented currently)
to choose and create extra Sin wave tones.
It was part of an experiment into algorithms to recognize pitch and melody.
