What sort of artifacts? Dropouts and glitches? Or just poor-quality
reverb? I do think the reverb opcode isn't very nice-sounding at
all; lots of distinct echoes, not very smooth. reverb2 is a bit
better but still IMHO bad.
I've tried a lot of csound reverb orc/sco's; most sound pretty bad,
frankly. Two notable exceptions are:
Hans Mikelson's reverb.orc (but NOT the gardverb.orc) from
http://www.werewolf.net/~hljmm/csound/ - sounds very good but runs
VERY slow (nowhere near realtime on my Celeron 333);
and Sean Costello's waveguide reverb at:
http://media.dr.rhbnc.ac.uk/csound/list/msg03983.html
which sounds quite nice and does run realtime on my system.
Freeverb is fast and sounds *very* nice. I wish somebody would
figure out how to hack freeverb into a csound opcode. I tried but
had to face the fact that I had no idea what I was doing. I'm amazed
that I got an opcode that actually runs - but it didn't sound
anything like the ladspa freeverb!
If anyone wants to give it a try, you can see my crude attempts at
