commandline tool to compare audio files
Project description
audiodiff is a library that can be used to compare audio files.
Examples:
>>> import audiodiff >>> audiodiff.equal('airplane.flac', 'airplane.m4a') False >>> audiodiff.audioequal('airplane.flac', 'airplane.m4a') True >>> audiodiff.tagsequal('airplane.flac', 'airplane.m4a') False >>> audiodiff.checksum('airplane.flac') 'ffa0d242f8642b20e90f521a898a0ab5' >>> audiodiff.checksum('airplane.m4a') 'ffa0d242f8642b20e90f521a898a0ab5' >>> audiodiff.tags('airplane.flac') {'artist': 'f(x)', 'album': 'Pink Tape', 'title': 'Airplane'} >>> audiodiff.tags('airplane.m4a') {'title': 'f(x) - Pink Tape - Airplane'} >>> audiodiff.tagsdiff('airplane.flac', 'airplane.m4a') --- airplane.flac +++ airplane.m4a -artist: f(x) -album: Pink Tape -title: Airplane +title: f(x) - Pink Tape - Airplane
It can be also used as a commandline tool. When used as a commandline tool, it supports comparing audio files in two directories recursively. Audio files with the same name except for the extensions are considered to be compared.
Commandline examples:
$ ls . -R mylib1: a.flac b.flac cover.jpg mylib2: a.m4a b.m4a cover.jpg $ audiodiff mylib1 mylib2 Audio streams in mylib1/a.flac and mylib2/a.m4a differ Audio streams in mylib1/b.flac and mylib2/b.m4a differ --- mylib1/b.flac +++ mylib2/b.m4a -album: [u'Purple Heart'] +album: [u'Blue Jean'] +date: [u'2001'] Binary files mylib1/cover.jpg and mylib2/cover.jpg differ
Supported audio formats
Currently audiodiff can only read FLAC, M4A, MP3 files.
Caveats
Tag reading is done by mutagenwrapper for which there isn’t a stable version yet. It may omit some tags, thus incorrectly reporting tags in files being compared are equal while they are not.
Install
audiodiff can be installed with pip. To install, run:
pip install audiodiff
For help using the commandline tool, run audiodiff -h.
Dependencies
audiodiff requires ffmpeg to be installed in your system. The path is ffmpeg by default, but you can change it by following ways (later rules take precedence over earlier ones):
audiodiff.FFMPEG_BIN module property
FFMPEG_BIN environment variable
--ffmpeg_bin flag (commandline tool only)
