Linux Audio conference, Saturday

Today Dave Phillips gave the keynote speech. on the history of Linux audio from the development of OSS in 1992 to this, the 10th Linux Audio Conference. Dave literally wrote the book on Linux Audio & Sound and has been a long time contributer to Linux Journal with a monthly articles and created the Linux Audio website and maillist. Dave had interesting stories about the people who made Audio viable on Linux including Rt kernel developer Ingo Molnár, a RedHat employee, and fedora based PlanetCCRMA repository by Fernando Lopez-Lezcano.

More great talks on the technology including more Ambisonics, sound over UDP, resampling, the Faust library (this is really cool, I must learn how to use Faust) and a touch screen implementation.

The most interesting talk of the day was about the composition Rite of the Earth by Krzysztof Gawlas. This project is a great mix of the arts and computers, started with artists making ceramic instruments, drums, flutes, shakers, gongs, chimes and ocarinas. A sonic analysis of the instrument samples allowed Krzysztof to make a score of the samples using SuperCollider. The sixth movement of the piece was featured at the evening concert and was very beautiful.

The evening concert also featured some great live performances. Kevin Erste's piece Birches was preformed with John Graham on viola, a beautiful mix of live and computer processed sounds. Chris Chafe and Roberto Morales performed the piece Princesa Chontales using a the prototype cello made by Max Mathews, a daxaphone played by Chafe, and Morales played percussion, flute and piano with two Wii controllers rubber banded to his sleeves, to computer process the sound.

The music continued in the Coho coffee house with live performances of Miller Puckette on guitar, Zachery Berkowitzi on his mallet controller, Grant Brownyard played some computer game music he created and Harry van Haaren created some dance music with his Luppp program.
