Usage

mppenc [--options] [input_file] [output_file]

Overview

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

`FC-F[0]`	STDIN (only RIFF WAVE files)
`FC/dev/audioF[0]`	soundcard (OSS, 44.1 kHz)
`FC*.wavF[0]`	RIFF WAVE file
`FC*.raw\|cdrF[0]`	RAW PCM file (2ch, 16bit, 44.1kHz)
`FC*.pac\|lpacF[0]`	LPAC file (Windows only)
`FC*.fla\|flacF[0]`	FLAC file
`FC*.apeF[0]`	Monkey's Audio file (APE extension only)
`FC*.rka\|rkauF[0]`	RK Audio file (Windows only)
`FC*.szF[0]`	SZIP file
`FC*.shnF[0]`	Shorten file
`FC*.wvF[0]`	Wavpack file
`FC.ofrF[0]`	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

`FC*.mpcF[0]`	Musepack file
`FC*.mp+\|mppF[0]`	MPEGplus file (deprecated)
`FC-F[0]`	STDOUT
