💖 NAME 💖

mppenc — the Musepack lossy audio codec encoder. it squeezes your audio, bestie. lossily. 🎀

✨ SYNOPSIS ✨

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

🦋 DESCRIPTION 🦋

okay so mppenc is a Musepack lossy audio codec encoder. and Musepack? it's a lossy audio codec that was literally built for one specific job: transparent compression of stereo audio at bitrates of 160-180 kbit/s. that's its whole thing. it ate and left no crumbs. 💅

🌸 INPUT FILES 🌸

like, it'll take your audio from a bunch of places:

  • - — STDIN. only RIFF WAVE files, no cap.
  • /dev/audio — your soundcard (OSS, 44.1 kHz). iconic.
  • *.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)
rn it only supports 32, 37.8, 44.1 and 48 kHz, 1-8 channels, 8-32 bit linear PCM. periodt. and bestie, if you're using one of the lossless compressed formats, a proper binary must be installed within the system's $PATH. no binary, no vibes. 😭

🎀 OUTPUT FILES 🎀

  • *.mpc — Musepack file 👑
  • *.mp+|mpp — MPEGplus file (deprecated — it's giving vintage, not in a cute way)
  • - — STDOUT

💅 OPTIONS 💅

the quality ladder, from "why" to "why not":

  • --quality 0.00 — below telephone, poor quality (~ 20 kbps)
  • --quality 1.00 — below telephone, poor quality (~ 30 kbps)
  • --quality 2.00, --telephone — telephone, low quality (~ 60 kbps)
  • --quality 3.00, --thumb — thumb, low/medium quality (~ 90 kbps)
  • --quality 4.00, --radio — radio, medium quality (~ 130 kbps)
  • --quality 5.00, --standard, --normal — normal (default), high quality (~ 180 kbps)
  • --quality 6.00, --extreme, --xtreme — extreme, excellent quality (~ 210 kbps)
  • --quality 7.00, --insane — insane, excellent quality (~ 240 kbps)
  • --quality 8.00, --braindead — braindead, excellent quality (~ 270 kbps)
  • --quality 9.00 — above braindead, excellent quality (~ 300 kbps)
  • --quality 10.00 — above braindead, excellent quality (~ 350 kbps)

also!! the quality scale is effective centesimally, meaning you can do stuff like --quality 4.25. the precision? unmatched. 🫶

and here's the rest of the options, bestie:

  • --silent — repress console messages (default: off)
  • --verbose — increase verbosity (default: off)
  • --longhelp — print long help
  • --stderr FILE — append messages to file
  • --neveroverwrite — never overwrite existing output file (default: off)
  • --interactive — ask to overwrite an existing output file (default: on)
  • --overwrite — overwrite existing output file (default: off)
  • --deleteinput — delete input file after encoding (default: off)
  • --beep — beep when encoding is finished (default: off)
  • --unicode — unicode input from console (Unix only)
  • --tag key=value — add tag 'key' with 'value' as contents
  • --tagfile key=file — add tags, take values from a file
  • --tag key — add tags, take values from console
  • --artist 'value' — shortcut for --tag 'Artist=value'
  • --album 'value' — shortcut for --tag 'Album=value'

🌈 more tag keys if you're feeling extra 🌈

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... (yes, media shows up twice, that's just how it is, don't look at me 🙈)

🧚 trimming + shaping the audio 🧚

  • --skip x — skip the first x seconds (default: 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 (default: 0.0)
  • --fadeout x — fadeout in seconds (default: 0.0)
  • --fadeshape x — fade shape, see http://www.uni-jena.de/~pfk/mpc/img/fade.png (default: 1.0)
  • --scale x — scale input signal by x (default: 1.00000)
  • --scale x,y — scale input signal, separate for each channel

🔥 EXAMPLES 🔥

copy these, they're slay:

mppenc inputfile.wav
mppenc inputfile.wav outputfile.mpc
mppenc --radio inputfile.wav outputfile.mpc
mppenc --silent --radio --pns 0.25 inputfile.wav outputfile.mpc
mppenc --nmt 12 --tmn 28 inputfile.wav outputfile.mpc
