=Introduction=
'''Musepack''' is a lossy audio compression scheme created by [[Andree Buschmann]]. It is strongly based on the [[MPEG-1]] Layer-2 ([[MP2]]) algorithms. Informal listening tests have demonstrated that MPC is the best [[lossy]] audio encoder at ~140kbps and above [[bitrate]]s, but competes less well at lower, 'streaming' bitrates such as 32/48/64kbps. This is due to MPC being a [[subband]] [[codec]] as well as the fact that very little optimization has gone into such low [[bitrate]]s. As can be seen in various 128kbit/s listening tests (see below), despite the fact that MPC has been optimized little for such bitrates it is in the same class of other modern competitors such as [[AAC]] and [[Ogg Vorbis]].

Pros

  • Best lossy encoder for mid-high bitrates
  • Suffers from far less "problem cases" than other formats.
  • Very fast encoding/decoding
  • Designed to be transparent by default at --standard setting.
  • Open source encoder
