I took 8192 instead. > The sound system should be a little more intelligent, and scale the buffer size according to the sample rate used, instead of using a fixed buffer size. 8000 bytes of buffer at 8kHz gives 1 second of delay. 8000 bytes of buffer at 96kHz gives 83ms of delay. I would recommend 2*50ms or 2*25ms of buffer. > I'm assuming the default buffersize (16k) is fair enough. > --HPS
