Original sentence: In May 2004, a series of controlled tests (as reported on Slashdot) concluded that aoTuV (a fork of Ogg Vorbis) and Musepack would be the two best available lossy codec for high-quality audio compression at bitrates of 128kbit/s and upwards, compared with MP3, AAC, WMA, or ATRAC.It is now officially declared "patentless" by their site, but without any proof or explanation about the status change.Its license/patent status however seems to remain somewhat murky: MPC was originaly under threat from multiple patents (MP2, PNS, subband), and thus remains not pre-included with most audio softwares.The psychoacoustic model of MPC is based on MPEG ISO model 2, but is extended by CVD (clear voice detection).net Website of the Musepack project
