Joerg Mueller 174eccf078 Huge new year audio commit!
* Refactored the whole audaspace library to use float as sample format over all readers.
* Added new Readers like the linear resampler, envelope, lowpass, highpass and butterworth.
* Note: The butterworth filter isn't working correctly, some bug in there... Maybe also true for the envelope.
* Added a sound to f-curve operator that behaves mostly like the soundtracker script of technoestupido.
