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.
