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

       .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.

OUTPUT FILES
