another note is that when it comes to actual processing and synthesis a higher sample rate matters a lot more than just with recorded audio. It's not just a case of "oh, 44.1 can reproduce any frequency in human hearing, so it's all good" because a lot of actual dsp algos don't perform the same at all rates. Just switch back and forth between 44.1 and 96 with a few different softsynths (ones that don't automatically internally oversample of course) and you'll hear differences (because even though 44.1 should be enough in theory, in practice it sometimes messes with the math because the real world of code and analog emulation isn't that idealized).

As an added bonus, running at 96 also cuts your latency in half (which is awesome, especially since most/all audio interfaces have "safety buffers" which are added to your normal audio buffer, so lowering your buffer size can't touch the amount of latency introduced by the safety buffer which is locked at anywhere from 10 to 1000 samples depending on soundcard... But raising the sample rate can)

Actually what happens is that some plugins produce aliasing products and don't filter them out. It's just bad programming. Running these at 96kHz just gives aliasing at a different set of frequencies, so it's neither better nor worse. And I'm certain most computers are powerful enough that they can give a low enough latency at 44.1kHz that it's not an issue.

I've noticed this before, and used to run my D/A interface at 88 kHz. Unfortunately, after updating the driver, I'm no longer offered that option. :cry:
