Posted on April 10, 2008, Chris Upcoming PS3 Firmware Will Add DTS-HD Master Audio
For any of our audiophile readers with a PlayStation 3, you’ll be happy to hear that the upcoming PS3 firmware update (v2.30) will add support for DTS-HD Master Audio output for Blu-ray videos. Odds are if you aren’t familiar with this stuff already, you probably won’t be enjoying all sorts of 7.1 goodness.
Some info from PlayStation.Blog:
The technology delivers audio at the incredibly high rate of 24.5 mega-bits per second (Mbps) on Blu-ray disc, which is significantly higher than standard DVDs. DTS-HD Master Audio also offers 7.1 audio channels at 96k sampling frequency/24 bit depths, so you’ll be totally immersed in the sound. The firmware update will add DTS-HD High Resolution Audio as well, which is a similar output technology that requires less disc space. You can read more about both codecs here.
I guess my decision to buy a 7.1 system recently instead of 5.1 might actually come in handy, provided I can find a movie that actually supports 7.1.
