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.

Generates a playlist of files in directories in random directory order. Preserves the alphebetical ordering within directories but lists directories in a random order. Enables you to create a music playlist of random albums if you keep albums in separate directories. lots of directory scanning configuration options and size limiting. Will also produce a playlist to fit the free space on a specified device. Good for grabbing a random selection of albums to transfer to your device or just to be able to play albums in a random order if your device doesn't have this feature. You can also use it to generate separate playlists for separate directories by running it multiple times in another script (this is my current use for it in my Android device).
