Hi.
I am working on simple experimental wavetable playback
system for Linux, currently software only.
I want to accomplish pitch shifting, much like
fluidsynth does.
I am curious, what algorithm does fluidsynth use to do
real-time pitch shifting/pitch bending? Will someone
shed some light on some of these details?
My understanding is that pitch bending/pitch shifting
requires sample rate conversions which seems to be a
pretty complex process.
I also noticed that running fluidsynth on my 2GHz K7
PC, the CPU utilzation sometimes exceeded 75%. What
routines in fluidsynth consume so much CPU?
Thank you!
Kai.
