The Bauer stereophonic-to-binaural DSP (bs2b) library and plugins is designed to improve headphone listening of stereo audio records. Recommended for headphone prolonged listening to disable superstereo fatigue without essential distortions.
Clean implementation (in ANSI-C) of the Wavelets Transform. It works fairy good as a sparser, which can be combined with a compression algorithm (by using programs like bzip and gzip) to achieve high compression ratios (as good as mp3's).
It's a really easy-to-use front-end to programs like cdda2wav and bladeenc intended to convert an audio CD to mp3 files. It allows to access to the online CD database (freedb) to get disk's name and songs' names.
