SYNOPSIS

mppenc [--options] [input_file] [output_file]

DESCRIPTION

mppenc is a Musepack lossy audio codec encoder. Musepack is a lossy audio codec specifically optimized for transparent compression of stereo audio at bitrates of 160-180 kbit/s.

INPUT FILES

-
STDIN (only RIFF WAVE files)
/dev/audio
soundcard (OSS, 44.1 kHz)
*.wav
RIFF WAVE file
