Is Anything Above DTS 768 Useful? 2018-03-02 03:45:15 To this point A/V audio formats haven't really mattered to me (put the receiver on direct, tell the HTPC it supports everything, ignore). However, I have started ripping discs and I am staggered by the size of the audio track on a Blu Ray! Doing the math from red book bit rates, it seems that properly encoded 7.1 should never require more than 617 kbps (assuming that the .1 channel is sampled at 200hz and hence virtually irrelevant). I have at least one file approaching 10 mbps just for audio! That is a huge amount of storage being consumed by nonsense. There doesn't seem to be any rhyme or reason to it, since in the case above the sample rate is only 48khz and I don't think that 24-bit audio explains such a high rateMy question is twofold: Ignoring object-based audio (which my receiver doesn't support), is there any argument for these higher bit rate tracks? If not, is there any way to bring these back down to the real world? I would like to keep them in a form that my receiver can decode so that my whiddle passively cooled HTPC has one less thing to worry about.Thanks!
