DESCRIPTION
wavplay plays a WAV format file to the audio device (by default
/dev/dsp ) reading WAV parameters from the input file header.
(Command-line options will override these defaults, if you know better
or for special effects.)
wavrec samples the audio device and writes a WAV file. Command-line
options provide complete control over the resolution and duration of
sampling.
Both wavplay and wavrec allow the audio device to be locked for
exclusive access.
