Mp3Wrap ~ Create mp3 Albums


Mp3Wrap is a free and independent alternative to AlbumWrap. It’s a command-line utility that quickly wraps two or more mp3 files into one single large playable mp3, without losing filenames and ID3 information (and without decoding or encoding). It’s also possible to include other non mp3 files, such as playlists, info files and cover images inside the new mp3. You can easily produce a large mp3 file that you can split at any time by using mp3splt and in few seconds you’ll have all the original files again! It’s useful because files created with Mp3Wrap are much easier to share.

beets ~ The Music Geek’s Media Organizer


The purpose of beets is to get your music collection right once and for all. It catalogs your collection, automatically improving its metadata as it goes using the MusicBrainz database. Then it provides a bouquet of tools for manipulating and accessing your music.

Because beets is designed as a library, it can do almost anything you can imagine for your music collection. Via plugins, beets becomes a panacea:

  • Fetch or calculate all the metadata you could possibly need: album art, lyrics, genres, tempos, ReplayGain levels, or acoustic fingerprints.
  • Get metadata from MusicBrainz, Discogs or Beatport. Or guess metadata using songs’ filenames or their acoustic fingerprints.
  • Transcode audio to any format you like.
  • Check your library for duplicate tracks and albums or for albums that are missing tracks
  • Browse your music library graphically through a Web browser and play it in any browser that supports HTML5 Audio and lots more.

Mp3splt ~ Split Albums Into Songs


Mp3Splt-project is a cross-platform utility to split mp3, ogg vorbis and native FLAC files by selecting a begin and an end time position, without decoding. It’s very useful to split large mp3, ogg vorbis or FLAC files to make smaller files or to split entire albums to obtain original tracks. If you want to split an album, you can select split points and filenames manually, you can get them automatically from CDDB (internet or a local file) or from .cue files. Also supports automatic silence splitting, which can be used to adjust cddb/cue split points. Trimming using silence detection is also available. You can extract tracks from Mp3Wrap or AlbumWrap files in few seconds.
