Additional Firmware 2.30 details
Thankfully, the guys and gals at the Official PlayStation Blog explained what the heck that means:
"DTS-HD Master Audio is literally bit-for-bit identical to the studio master recording and makes movie soundtracks and sound effects truly come to life. 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."I'm glad we cleared that one up! PS3 Attitude are sure audiophiles everywhere are salivating right now.
