What sort of surround sound support will the PlayStation 3 have?
For in-game audio, Dolby Digital, Dolby Pro Logic II and DTS are all supported and processed by the Cell. However, keep in mind that since all the audio processing is done by the Cell, developers can use or create whatever audio codecs they desire. 7.1 channel support is already announced, but again, given developers’ ability to program their own codecs, this may only be a starting point.
