BAC is a command-line tool that converts, to a target audio file format, all the audio files stored in a directory tree of any depth. Supported file formats are OGG, FLAC, MP3, AAC, ALAC, WAV, in all ways, and WMA as source. Main audio tags are preserved in the process, as well as most file name characters (white spaces, question marks etc).
BAC runs on Linux and probably most UNIX-type OSes. 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.
- The program attempts carefully at supporting most characters in file names, especially white spaces.
- This program runs on Linux or Cygwin.
- This program is a shell script designed to be easily adapted to other formats, OSes or preferences.
