Perceptual audio codec. The main technique used is a vector quantizer. The codebook is about 500kb in size, this results in long encoding times but fast decoding.
http://www.twinvq.org/english/index_en.html has the official encoder and player for Windows.
http://www.mp3-tech.org/programmer/sources/refsoft990809.tgz has code for the vqf version that made it into AAC.
http://www.intel.com/cd/software/products/asmo-na/eng/perflib/ipp/219611.htm?prn=y Intel shares some code for AAC flavored vqf.
http://www.csn.ul.ie/~mel/projects/linux/vqfplugin/ hosts a native VQF plugin for XMMS. It includes Nippon TT's binary-only encoding and decoding libraries and C++ header files.
