Ghost Audio Codec

Xiph details what they hope will be their codec to supersede Vorbis.

Ghost intends to improve and expand upon the Vorbis feature set in the following ways:

  • Near-headerless operation
  • Elimination of pre-echo
  • Inherently bit-exact decode
  • Lossless encoding ability
  • Reduced/bounded resource usage
  • Extension of encoding sweet spot for CD-rate audio to as low as 16kbps (factor of four over Vorbis)

It gets really technical from there.
