defrost

• split broken icecast recordings into separate mp3s
• MIT-Licensed, 2019-06-01, ed @ irc.rizon.net, github, pypi

features

• silence detection -- finds the best part to split at
• mp3 parser -- clean splits at frame boundaries
• icy-meta parser -- extract artist/title from inband metadata
  • dynamic recalibration to recover from server glitches
• charset detection -- UTF8, latin-1, shift-jis and friends, all good
• ID3 tags -- uses mutagen to write aritst/title into the files
• timestamping -- the date/time that the song was played live
• support for other input formats:
  • loopstream recording

installation

• get the latest release from pypi: python3 -m pip install --user -U defrostir
• or the latest commit from github: python3 -m pip install --user -U https://github.com/9001/defrost/tarball/hovudstraum

usage

from an internet radio station:

wget -U MPlayer --header 'Icy-MetaData: 1' -St1 'https://stream.r-a-d.io/main.mp3'
# wait until the show is over, then abort the download
python3 -m defrostir main.mp3

from a loopstream recording:

python3 -m defrostir -i ls Loopstream-2021-10-02_22.53.44.mp3

notes

versions x.y.1 have chardet as a dependency, while x.y.2 have charset-normalizer (preferred) and are otherwise identical; setup.py rls will produce both to avoid a pypi package selection bug
