Hi all:
Since I have been asking a lot of "ensemble" questions in the past few days, I
have made an MP3 of my Csound experiments and put it on line. Go to
http://www.haint.com/sounds/
and download strings.mp3. The sound is a digital recreation of the string
ensemble/phaser combo: bandlimited pulse waves, going into a three parallel
delay line chorus (with two 3-phase LFOs, one at .33 Hz, one at 5.5 Hz) with the
three delay line outputs mixed together, into an allpass filter phase shifter (6
stages, 3 notches), into a feedback delay network reverberator.
I have also put up various other soundfiles, all created within Csound. Some of
these should be of interest to Synth-DIY readers, as they are direct digital
translations of analog circuits - for example, beethoven.mp3 features frequency
shifting using an allpass-based Hilbert transformer, to obtain both inharmonic
and "barberpole phaser" effects. Some of these are purely digital in nature, but
still sound pretty cool IMHO.
Most of the compostions are somewhat academic in nature, as they were composed
for a class in a conservative music department (the professor wasn't too happy
when I demonstrated some of my signal processing techniques on "Sweet Leaf" -
alright now, won't you listen). However, most of my signal processing work has
been aimed towards developing techniques that would be useful to many types of
music, not just atonal postmodern blah boring blah. A lot of the techniques I
first heard about on this list - thanks, guys.
I am working on a more extensive website. I will keep y'all posted of anything
that would be of interest to the list.
