Open Source Perl Music Composition Software

Livemix will search directory tree for audio files, assuming each of them is a separate track, then group them into sessions based on file size, and then create a downmix for each session. Silent tracks are ignored, the others are processed by applying some effects such as compand, then normalized and then combined into downmix with equal volume. Sessions are named by the time of recording in YYYYMMDD-HHMMSS format. Intended use is to quickly generate mp3 previews of live multitrack music recordings (such as rehearsals or live performances), created by some sound recording software (Avid ProTools or Audacity for example). Livemix uses SoX sound processing utity to do all the work with tracks preprocessing and mixing, and LAME mp3 encoder to produce final mp3 file. Therefore, livemix needs sox and lame executables to be in search path or in the same dir as livemix executable.

TagTools for Linux is a set of scripts which can be used to manipulate audio tags of various audio formats (MP3, OGG, FLAC etc). In fact, it is an implementation of the Audio::TagLib library (http://search.cpan.org/dist/Audio-TagLib/lib/Audio/TagLib.pm), and provides it with a command-line and dialog-based interface. TagTools should also work correctly with tags written in different codepages (utf8, cp1251 etc). The following scripts are included: tag2fname - this is a command-line tool to rename a number of files using the information extracted from audio tags in a specified format. tag2fname.dialog - a dialog-based interface for tag2fname. fname2tag - another command-line tool to convert file names into audiotags using a specified format. batchtag.dialog - a dialog-based tool for batch tag editing. tagedit.dialog - dialog-based tool for editing individual audio file tags.
