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. |
Using
|
This should be considered an alpha release; error handling is rather braindead at the moment. Preferences are stored in the file ~/.hypersonicrc . It is python code to be executed. |
Tutorial

A brief tutorial covering the essentials of the python API: tutorial.py |

Plugins

Writing your own plugins. Coming soon. |
Downloads
|
Here it is. hypersonic-1.2.0.tar.gz hypersonic-1.0.2.tar.gz This is a binary for MacOSX 10.2. hypersonic-1.0.1.bin.OSX.tar.gz |
Dependancies
|
python2.2 debian: python-dev (rpm: python-devel) To compile on OSX you will need the developer tools. |
Todo
|
Better integration with python (via pyrex), raise exceptions. More documentation. Document c API, architecture. Release more scripts (there are many). Port to windows. Mailing list, CVS. Interface with libsndfile, Open Sound Control, LADSPA, libfftw, numarray. |
Feedback
|
I'd like to know how you go with this, especially if you get stuck send me an email.

History
|
Work on this version began late in 2001.
It was initially intended to be a robust sound engine
for a 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. |
