MPC Encoder 1.30.0 --stable-- (C) 1999-2009 Buschmann/Klemm/Piecha/MDT Built Feb 26 2009 20:33:36 Usage: mpcenc [--options] mpcenc [--options] Input_File must be of the following: - stdin (only RIFF WAVE files) *.wav RIFF WAVE file *.raw/cdr Raw PCM (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_File must be of the following: (or generated from Input_File) *.mpc Musepack file *.mp+/mpp MPEGplus file (Deprecated) - stdout /dev/null trash can Profiles and Quality Scale: Option of using a profile (--radio) or mapped quality scale (--quality 4.0). In addition, quality scale is effective centesimally. (i.e. --quality 4.25) Available options are as follows: below telephone (--quality 0.00) poor quality (~ 20 kbps) below telephone (--quality 1.00) poor quality (~ 30 kbps) --telephone (--quality 2.00) low quality (~ 60 kbps) --thumb (--quality 3.00) low/medium quality (~ 90 kbps) --radio (--quality 4.00) medium quality (~ 130 kbps) --standard (--quality 5.00) high quality (dflt) (~ 180 kbps) (or --normal) --extreme (--quality 6.00) excellent quality (~ 210 kbps) (or --xtreme) --insane (--quality 7.00) excellent quality (~ 240 kbps) --braindead (--quality 8.00) excellent quality (~ 270 kbps) above braindead (--quality 9.00) excellent quality (~ 300 kbps) above braindead (--quality 10.00) excellent quality (~ 350 kbps) Bitstream formating: --no_ei do not write encoder information packet (dflt: off) --no_st do not write the seek table (dflt: off) --num_frames x x = 0..7 number of frames in packet = 4^x (dflt: 3) --seek_distance x x = 0..15 keep a seek table entry every 2^x audio packet (df lt: 1) File/Message handling: --silent repress console messages (dflt: off) --verbose increase verbosity (dflt: off) --longhelp print this help text --stderr foo append messages to file 'foo' --neveroverwrite never overwrite existing Output_File (dflt: off) --interactive ask to overwrite an existing Output_File (dflt: on) --overwrite overwrite existing Output_File (dflt: off) --deleteinput delete Input_File after encoding (dflt: off) --beep beep when encoding is finished (dflt: off) Tagging (uses APE 2.0 tags): --tag key=value Add tag "key" with "value" as contents --tagfile key=f dto., take value from a file 'f' --tagfile key dto., take value from console --artist 'value' shortcut for --tag 'Artist=value' --album 'value' shortcut for --tag 'Album=value' other possible keys are: debutalbum, publisher, conductor, title, subtitle, track, comment, composer, copyright, publicationright, filename, recordlocation, recorddate, ean/upc, year, releasedate, genre, media, index, isrc, abstract, bibliography, introplay, media, language, ... --unicode Toggle unicode input from console on/off if autodetection doesn't work. This switch MUST be before any tag switch. Audio processing: --skip x skip the first x seconds (dflt: 0.0) --dur x stop encoding after at most x seconds of encoded audio --fade x fadein+out in seconds --fadein x fadein in seconds (dflt: 0.0) --fadeout x fadeout in seconds (dflt: 0.0) --fadeshape x fade shape (dflt: 1.0), see http://www.uni-jena.de/~pfk/mpc/img/fade.png --scale x scale input signal by x (dflt: 1.00000) --scale x,y scale input signal, separate for each channel Expert settings: ==Masking thresholds====== --quality x set Quality to x (dflt: 5) --nmt x set NMT value to x dB (dflt: 6.5) --tmn x set TMN value to x dB (dflt: 18.0) --pns x set PNS value to x dB (dflt: 0.0) ==ATH/Bandwidth settings== --bw x maximum bandwidth in Hz (dflt: 234674215112136740000000000000 000000000.0 kHz) --minSMR x minimum SMR of x dB over encoded bandwidth (dflt: 1.0) --ltq xyy x=0: ISO threshold in quiet (not recommended) x=1: more sensitive threshold in quiet (Buschmann) x=2: even more sensitive threshold in quiet (Filburt) x=3: Klemm x=4: Buschmann-Klemm Mix x=5: minimum of Klemm and Buschmann (dflt) y=00...99: HF roll-off (00:+30 dB, 99:-30 dB @20 kHz --ltq_gain x add offset of x dB to chosen ltq (dflt: +0.0) --ltq_max x maximum level for ltq (dflt: 76.0 dB) --ltq_var x adaptive threshold in quiet: 0: off, >0: on (dflt: 1) --tmpMask x exploit postmasking: 0: off, 1: on (dflt: 1) ==Other settings========== --ms x Mid/Side Stereo, 0: off, 1: reduced, 2: on, 3: decoupled, 10: enhanced 1.5/3 dB, 11: 2/6 dB, 12: 2.5/9 dB, 13: 3/12 dB, 15: 3/oo dB (dflt: 11) --ans x Adaptive Noise Shaping Order: 0: off, 1...6: on (dflt: 6) --cvd x ClearVoiceDetection, 0: off, 1: on, 2: dual (dflt: 2) --shortthr x short FFT threshold (dflt: 5.0) --transdet x slewrate for transient detection (dflt: 100.0) --minval x calculation of MinVal (1:Buschmann, 2,3:Klemm) Examples: mpcenc inputfile.wav mpcenc inputfile.wav outputfile.mpc mpcenc --radio inputfile.wav outputfile.mpc mpcenc --silent --radio --pns 0.25 inputfile.wav outputfile.mpc mpcenc --nmt 12 --tmn 28 inputfile.wav outputfile.mpc
