Hi, I want to document some of the constraints of the alsa resampler. Here is what I understand, and I would like someone to verify my statements before I document them. 1) The buffer and period sizes for the sound card hardware to resampler are limited to the max buffer and period sizes available on the hardware. As a result, the available buffer and period sizes vary depending on hardware utilised. 2) The resampler converts one hardware period size at a time. This results in the buffer and period size constraints explained in (1) arriving at the application as a direct ratio of source and destination sample rate. e.g. hardware has 2 periods of 1024 frames running at 48000 Hz. application will see 2 periods of 1024 * 44100 / 48000 = 940.8. This is rounded down to 940 frames. So the user application sees 2 periods of 940 frames. If user space asks for 2 periods of 1024 at 44100 hz it will fail. The above 2 points were true some time ago. Has anything changed? Kind Regards James ------------------------------------------------------------------------- Take Surveys. Earn Cash.
