flac2ogg

Flac2ogg is an automated Audio file converter.

At the beginning, aim of flac2ogg was to produce high quality ogg files out of (preferably) lossless formats like FLAC/WAVE/WavePack. Over time it evolved of ability to produce small-sized mp3 files out of anything.

Of course there is no constraints on what source files would be and what output format will be, so there is a possibility to create ogg form low quality mp3 files, nevertheless it doesn't make any sense :) This script automate conversion between different type of audio formats.

Requirements

• python 3

• mutagen python library for tag read/write

• vorbis tools for ogg files encode/decode

• opus tools for opus files encode/decode

• lame for mp3 files encode/decode

• flac for flac files decode

• mac for Monkey audio codecs/ape files decode

• wavpack for wavpack files decode

• mplayer for m4a files decode

• shntool and cuetools for splitting monolithic CD dump files

Supported formats

Conversion can be performed from the following formats:

• FLAC

• MP3

• MP4

• WAVE

• WavePack

• Ape

• Ogg Vorbis

• Ogg Opus

Currently supported encoders:

• Ogg Vorbis

• Ogg Opus

• MP3 (lame)

There is an option to set the quality for the encoders - for Vorbis files there would be used an -q option for oggenc command, for the mp3 format -V option would be used for lame command and --bitrate for opusenc for the Opus files. Consult corresponding encoder man pages for details.

Usage

Given that there are couple of music files, simplest usage is as follows:

$ flac2ogg.py directory_of_music_files/*

All files from that directory will be encoded to opus by default. If there are already some opus files, new files would have _encoded_ added into the filename. Note, that output files will be placed next to the original files.
