I'm the creator of AudioMulch, software for live music performance.

My open source projects:

• PortAudio - A cross-platform audio I/O library that I co-founded with Phil Burk.
• reacTIVision - Marker tracking library. I invented the "amoeba" fiducial markers.
• oscpack - A popular C++ Open Sound Control (OSC) library
• oscgroups - A peer-to-peer multicast (peercast?) infrastructure for OSC

I'm available for freelance work. My skills include: full lifecycle software design and implementation, troubleshooting, C/C++, real-time audio, network programming, user interfaces, Qt, Python, Lua. No project is too strange or too interesting. Platform experience Windows: lots, Mac OS X: a fair bit, Linux: some, iOS: a bit, Android: a tad.
