The Xbox 360 supports Dolby Digital software, sampling and playback rate of 16-bit @ 48 kHz (internal; with 24-bit hardware D/A converters), hardware codec streaming, and potential of 256 audio simultaneous channels. While powerful and flexible, none of these features represent any major change in how game music is made from the last generation of console systems. PCs continue to rely on third-party devices for in-game sound reproduction, and SoundBlaster is largely the only major player in the entertainment audio expansion card business.
