[linux-audio-dev] Fixed vs Floating point comparison.

2003-10-16 Thread Juan Linietsky
Benno Sennoner and I were discussing today on IRC about the usual fixed point vs floating point (regarding to some resampling code) We developed some tests and ran them on a variety of computers. It would be interesting if ladders here could run them on different computers (and specially non x86, l

Hallo, today the IRCAM Resonances festival started. I don't know how many of these concerts will be done with Linux (maybe none...) but there are several Pd sessions, so they at least *could* be done on Linux. Below is the announcement as posted by Guillaume Boutard on pd-list. Beware, that there
