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

*.raw|cdr

RAW PCM file (2ch, 16bit, 44.1kHz)
