NAME

wavplay, wavrec - play and record WAV files

SYNOPSIS

wavplay [-h,--help] [-q] [-s rate] [-S] [-M] [-b bits] [-i] [-k ipc-key] [-R] [-l] [-u] [-L] [-U] [-V,--version] [input-files]

wavrec [-h,--help] [-q] [-s rate] [-S] [-M] [-b bits] [-t secs] [-k ipc-key] [-R] [-l] [-u] [-L] [-U] [-V,--version] [output-file]

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.

AUTHOR

wavplay 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).
