NAME

pcmplay - utility to play raw PCM data

SYNOPSIS

pcmplay [options] [file1.pcm file2.pcm...]

DESCRIPTION

pcmplay is a simple filter for sending raw PCM data to the cross-platform ao audio library. It will read from files specified on the command line, or standard input if no files are specified.

To obtain PCM data, check if your audio programs have an option to redirect output to a file. With mpg123 this is the -s option. Included with the Ogg Vorbis library is a sample decoder that generates PCM output. Many mixers and audio programs come with PCM samples.
