ALSA PCM devices are assumed to run with their own clock, i.e., it is
not directly possible for applications to control when a playback device
reads data from the ring buffer, of when a capture device writes data to
it.  The ALSA API is designed for real-time opertation; it would not be
a good choice for batch conversions.
