Kwave is a 24-bit sound editor that allows simple operations, such as cut, copy, and paste. Some more effect functions with little complexity (Simple Filtering, Delay) are also implemented. More sophisticated analysis functions (spectrograms, sonagrams, pitch determination) are underway or partially done.

AeonWave-OpenAL is a thin OpenAL emulation layer that uses AeonWave to create one of the fastest rendering OpenAL implementations available. OpenAL is a cross-platform 3D audio API appropriate for use with gaming applications and many other types of audio applications. Its API style and conventions deliberately resemble those of OpenGL.
AeonWave is a cross platform, hardware accelerated, multi-threaded, and versatile stereo and 4D audio mixing library. By combining hardware accelerated rendering and a low memory footprint the library can handle almost any situation, from virtual synthesizer apps for smart phones to immersive simulation. It has a small, easy to use, fault tolerant, and consistent API, low latency support by using hardware acceleration, simultaneous support for stereo and 4D audio, audio frames with sub-mixing capabilities, support for stereo and 3D audio effects and filters, and a Freeware supplemental OpenAL implementation.
LibRaw is a library for reading RAW files obtained from digital photo cameras (CRW/CR2, NEF, RAF, DNG, and others). LibRaw is based on the source codes of the dcraw utility, though some of the drawbacks of dcraw have been eliminated. The users of the library are provided with an API to be used when writing their software programs.
DR14 T.meter is a commandline tool for computing the Dynamic Range of your music according to the procedure used in the offline meter released by the Pleasurize Music Foundation. It is very useful to measure how loud your music is and to understand that a good quality album always has a good dynamic.

beaTunes is an iTunes companion app capable of automatically analyzing your music collection to help you build better playlists. It analyzes BPM (beats per minute), silence at the beginning or end of a song, and the color (based on frequency spectrum) of a given song. Some of the data is stored through iTunes, and some is stored by beaTunes itself. beaTunes can suggest albums that would complement your music collection, display music charts, and help you find and fix errors in your song meta data, like typos and wrong genres. It also allows you to blog about selected songs or playlists.
