A polyglot programming group meeting in the heart of The Beave. We seem to talk a lot about oddball programming languages and their features. And the usual geekery you'd expect from a programmer's group.

This month's talk is by Richard Fobes:

"Faster than an FFT, the audio-oriented QRST (spectral transform)"

Based on the interest Phil and Ed expressed in my spectral transform, I've spent lots of time during the past two months further developing the software. Besides getting it to work better -- it still needs refinement -- I've ended up creating an audio-compression method I call QRST. I'll be playing sound files to demonstrate what the spectral transform, the audio-compression format, and decompression back into sound files can do, so this will be much more interesting than the words "spectral transform" suggest.

BTW, being faster than the FFT is just one of the side effects of having designed it for use with sound files. Fourier transforms are sooo ssllooww.
