Can't DTHD already do 96khz and up to 192khz? Whats make this process different?
l wonder how DTS will respond to this.
edit- this thread should be in the audio section.
Few people over the age of 25 can hear 20kHz. If you live in an urban or today's suburban environments and have either worked in noisy environments, spend a lot of time on subway platforms or go to music clubs or concerts, you probably can't hear anything over 15kHz, but even that doesn't matter because movie soundtracks start rolling off at relatively low frequencies.
However, there are other reasons to use higher sampling rates that benefit the audio. Any audio that has complex waveforms in which there are many changes in audio in short intervals will benefit because at lower sampling rates it's possible to miss changes in audio that come between the samples.
Think of it this way: you start out on 40th street. You wind up on 43rd street. Maybe you walked directly up Broadway from 40th street to 43rd street. Or maybe you headed west on 40th street to 8th Avenue walked up 8th avenue, then headed back east to Broadway and 43rd street. At high sampling rates, you picked up the whole route. At low sampling rates, you just picked up the starting and ending point. That's why higher sampling rates sound better (or more accurate) not because they increase the maximum possible frequency response. For that, 44.1kHz (CD sample rate) is enough.
