DESCRIPTIONwavplay plays a WAV format file to the audio device (by default
/dev/dsp ) reading WAV parameters from the input file header. (Com‐
mand-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 exclu‐
sive access.

AUTHORwavplay was almost totally rewritten for version 1.0 by Warren W. Gay
(wwg@ica.net) replacing earlier code by Andre Fuechsel (af1@irz.inf.tu-
dresden.de). Erik de Castro Lopo (erikd@zip.com.au) wrote the WAV
header I/O routines. This manual page was written by Stephen Crane
(jsc@cs.city.ac.uk).
