[linux-audio-dev] Buffer size settings - Mac/Windows

[Michael Ost]

Hi.

Does anyone out there know what the audio buffer size settings in
Windows and MacOS really mean? If you say "128 samples" does that
translate to 2 buffers of 128 samples --- one buffer playing, one buffer
filling --- or 2 buffers of 64 samples? Is it 256 samples of latency or
128?

I realize this isn't _exactly_ a Linux audio question, but perhaps
someone out there knows something about this. We're trying to get an
apples to apples comparison of our Linux/ALSA based system with a
Windows/MacOS system.

We set the ALSA driver to 2x128 and we get results that jibe more with
the 256 setting in Windows. 

But when we hooked a Windows system up to a scope it looked more like
the 128 sample setting was running 2x64 samples. So... we're confused.

Any pearls of wisdom out there? ... mo
