MP3packer is a program which can rearrange the data within an MP3 to fulfill specific goals. By default, the program generates the smallest MP3 possible (with the least padding). However, many people also use it to turn VBR files into CBR for use with players which don’t support VBR.
It can save space by storing frame data in the smallest possible frame. Usually MP3s are already stored in the most efficient way possible. However, for high-bitrate CBR files (like -b 320) there can be a lot of wasted space. ~ HydrogenAudio

DFasma ~ Compare Audio Files In Time & Frequency
DFasma is free open-source software which is used to compare audio files in time and frequency. The comparison is first visual, using waveforms and spectra. It is also possible to listen to time-frequency segments in order to allow perceptual comparison. It is basically dedicated to analysis. Even though there are basic functionalities to align the signals in time and amplitude, this software does not aim to be an audio editor.
Features:
- Can load about 25 different audio formats (thanks to libsndfile or libsox).
- Shows spectrogram, amplitude, phase spectra and group delay.
- Can play a filtered sound given a selected frequency band.
- Rectification of the spectrogram tilt (cepstral lifting).
- Can create and edit segmentation files.
- Can create and edit fundamental frequency (F0) files (thanks to REAPER).
- Runs under Linux, Mac OSX and Windows.

ListenBrainz ~ Open Source Online Song Logging
The ListenBrainz project is similar to the original AudioScrobbler®. Unlike the original project, ListenBrainz is open source and will publish its data as open data.
A team of former Last.fm and current MusicBrainz hackers created the first version of ListenBrainz in the space of a weekend. Since the original project was created, technology has advanced at an incredibly rapid pace, which made re-creating the original project fairly straightforward.

Subvert Audio ~ Encourage Musical Creativity
Subvert Audio is a music program designed to try and stimulate creativity in the user. To do this, it imposes certain restraints on the user, in an attempt to encourage more creative thought processes, and solutions to the problem these restraints introduce. In addition to the restraints imposed, Subvert Audio strives to encourage exploration of the program, and reward efforts to discover/create new ways of using it. It is, essentially, a program that is designed to be subverted, the idea being that in the process of doing so, the user’s creativity will be stimulated.
In some ways, the program is similar to graphical music programming languages such as Max/MSP et al. Indeed, prior knowledge of such environments could be seen as beneficial to Subvert Audio’s methods of stimulating creativity.
