Andrew Kelley 7238d29666 sample rate is exposed as a list of min/max pairs 2015-08-08 14:44:31 -07:00
Andrew Kelley c381526205 callbacks supply min and max frame count parameters
This changes the semantics of the callbacks so that instead of
a single `requested_frame_count` or `available_frame_count`,
the callbacks get a minimum frame count and maximum frame count.

The callback must write at least the minimum or get an underflow.
The minimum will be 0 on ALSA, PulseAudio, and Dummy, and will
equal the maximum on CoreAudio and JACK.

This ensures optimal behavior regardless of buffer size.
