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

       *.shn  Shorten file

       *.wv   Wavpack file

       .ofr   OptimFROG file (Windows only)

       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.
