NAME
mppenc - Musepack lossy audio codec encoder
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)
*.pac|lpac
LPAC file (Windows only)
*.fla|flac
FLAC file
*.ape Monkey’s Audio file (APE extension only)
*.rka|rkau
RK Audio file (Windows only)
*.sz SZIP file
*.shn Shorten file
*.wv Wavpack file

Currently only 32, 37.8, 44.1 and 48 kHz, 1-8 channels, 8-32 bit linear
PCM is supported. When using one of the lossless compressed formats, a
proper binary must be installed within the system’s $PATH.
OUTPUT FILES
*.mpc Musepack file
*.mp+|mpp
MPEGplus file (deprecated)
- STDOUT
