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.
