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 for- mats, a proper binary must be installed within the system's $PATH. OUTPUT FILES
