play - send a waveform file to the local audio output device.
play reads a waveform file (or as much of it as possible if
memory is limited) using opnwav and inwav in the libcwav library, and sends the file to the
Digital to Analog Converter (DAC) by calling function dac also
in libcwav. The current version of
play supports only monaural output. Consequently only one
channel of multi-channel files will be played. By default, this is the
first channel (channel #0) or left channel of stereo recordings.
At present, play recognizes no command line options.
