Hi there, I've been messing around with some man made Csound music for
a change, and exorted a short measure in several sample rates. I've
noticed that the higher sample ratess (88.2kHz and 96kHz) sound much
less vibrant than the lower ones. Anyone know why this is?

My best guesses are that either my hardware/software doesn't support
these higher sample rates properly, or that the higher sample rate is
indeed increasing the clarity and quality, and infact reducing some
kind of noise otherwise present in the lower sample rates, which to my
ears makes the audio sound richer, or brighter.

I've got audio rate and low frequnecy AMs between square waves. That
could be causing the effect then I guess! Good shout. I shall add some
frequency foldover to see if it replicates the lower sample rate
