PlayStation 3 Adding DTS-HD Audio Support

Sony has already established the PlayStation 3 in the eyes of many as the best Blu-ray player on the market - a sentiment definitely held by two owners in the TR office - but that doesn't mean there isn't still room for improvement. That (small) list of tweaks that are wanted is a fair bit smaller now though, as come the 15th of April, DTS-HD Master Audio and DTS-HD High Resolution Audio will become supported formats.

Just like Dolby TrueHD and PCM, DTS-HD MA offers studio-quality 7.1-channel audio, in this instance up to a 24.5MB/s, 96kHz 24-bit stream. While not as popular an audio codec as Dolby TrueHD there are still a reasonable number of Blu-ray films that use DTS-HD MA, a notable example being Die Hard 4.0, which has a 5.1-channel DTS-HD MA audio track.

Should there be insufficient space on a Blu-ray disc to have half its capacity taken up by the soundtrack DTS-HD High Resolution audio can also be used, offering a 6MB/s bit-rate audio stream. While that is certainly a lot less data, it should still prove sufficient for all but the most discerning listeners.

Firmware 2.3 will be available, as mentioned, on the 15th of April. Along with the new audio support, it will also see the arrival of the new and improved PlayStation Store. In addition to the updated interface, a beta of Metal Gear Solid Online will also be available.

All told a decent pair of updates.
