Hello all, The first release of pyjacktools is now available at <http://kokkinizita.linuxaudio.org/linuxaudio/downloads> Python C++ extensions and classes for audio. I wanted to demo these during the Audio Measurements workshop at LAC 2014, but we ran out of time... AudioFile Read/write audio files to/from numpy arrays. Reads anything libsndfile can read, and writes wav, wavex, amb, aiff, caf and flac, any number of channels. JackControl Simple Jack client allowing to connect arbitrary ports and control Jack transport. JackPlayer Multichannel (up to 64) audio file player. The interface is deliberately kept low level, but it's easy to create derived classes providing a higher level interface. This is the player used in the automated systems at La Casa del Suono in Parma. JackSignals Generate and capture arbitrary test signals from/to numpy arrays. Combined with numpy, matplotlib, pyqt, etc. this can be used to create anything from a simple measurement to sophisticated automated test systems. All four classes are documented using Python docstrings (use Python's help function to read these). Some simple examples are provided as well. The C++ extenstions should work with either Python 3.x or 2.7. The Python code is tested using Python 3.4, but will probably work even with 2.7. If not the required changes should be minimal. To install you need the Python setuptools, then just make and sudo make install. The examples require numpy and for some also matplotlib. Enjoy ! -- FA A world of exhaustive, reliable metadata would be an utopia. It's also a pipe-dream, founded on self-delusion, nerd hubris and hysterically inflated market opportunities. (Cory Doctorow)
