Command-line mass conversion of any directory tree of audio files.
...On Windows, it must be operated from the Cygwin environment.
It requires the following software to be installed:
- flac and metaflac (flac files only)
- vorbis-tools (ogg files only)
- faac and faad (aac files only)
- lame and madplay (mp3 files only)
- alac-decoder and mpeg4ip-utils (ALAC decode)
- ffmpeg (ALAC encode, wma decode)
- mplayer (wma decode)
- mp4v2-utils (AAC, ALAC, WAV decode)
BAC is now optimized for multiprocessing on multicore systems: a tunable number of cores can be used for simultaneous conversions.
