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

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 =================================== Michael Ost, Software Architect Muse Research, Inc. most(a)museresearch.com
