ALAC ~ Apple Lossless Audio Codec


The Apple Lossless Audio Codec (ALAC) is an audio codec developed by Apple and supported on iPhone, iPad, most iPods, Mac and iTunes. ALAC is a data compression method which reduces the size of audio files with no loss of information. A decoded ALAC stream is bit-for-bit identical to the original uncompressed audio file.

The Apple Lossless Audio Codec project contains the sources for the ALAC encoder and decoder. Also included is an example command line utility, called alacconvert, to read and write audio data to/from Core Audio Format (CAF) and WAVE files. A description of a ‘magic cookie’ for use with files based on the ISO base media file format (e.g. MP4 and M4A) is included as well.

This package contains ALAC code used in foobar2000 / foobar2000 Mobile; derived from Apple’s public ALAC code release.

Impro-Visor ~ Jazz Improvisation Adviser


Impro-Visor (short for “Improvisation Advisor”) is a music notation program designed to help jazz musicians compose and hear solos similar to ones that might be improvised. The objective is to improve understanding of solo construction and tune chord changes. There are other, secondary, things it can do, such as improvise on its own. It has also been used for transcription. Because rhythm-section (e.g. piano, bass, drums) accompaniment is automatically generated from chords, Impro-Visor can be used as a play-along device. Now having a wider array of accompaniment styles, its use is not limited to jazz.

Elpetozede ~ Split An Album Into Tracks


Elpetozede is a multi-platform, open source tool to split a wave file (.wav), which contains the complete audio recording of one side of a vinyl record or a cassette tape into single wav files, one for each track. It searches an Internet database (musicbrainz.org) for the album data, so, with a little luck, you won’t need to type all the track information by hand.
