First public release. Comments sought.

dsptools
========

Here be Python wrappers for portaudio, ladspa and libsndfile.
There are three modules: ladspa, sndfile, and portaudio.
They are independant of each other, ie. they should compile/run individualy.

Data interchange is type sensitive and uses numarray arrays to store sound data.

It's possible to segfault by doing stupid things, eg. from within the portaudio callback only some portaudio calls are allowed.

See the python scripts for example usage, *.pyx files for implementation, and *.pxi for underlying c library info.

http://sourceforge.net/projects/dsptools/

It's under tested, under documented, but it's pretty cool.
