I knew _someone_ would chime in about 23ms being "high latency."  :-)

LOL, but it is.

As far as I'm concerned personally, when using the computer as
effect-rack playing guitar or bass:
latencies between 10 and 20ms are the worst!

OK... Yes, in this use case. There's a lot of use cases where this is acceptable.

FWIW, several popular apps (esp. those doing Fourier Transforms, like
time-stretchers) will not work reliably at <256 frames/period.

Would you care to enlighten us which popular apps that are?
'fmit' for example uses FTT and works just fine at 32fpp.

Before I FUD someone else's application... a perfect example is StretchPlayer (using RubberBand). I can't get it to be RT-safe at <256... and it's marginal at 256.

Maybe I didn't configure it right...  ??
