5.1 24-bit audio ripped as stereo
Hey,

New to the whole audiophile world and I'm sure this topic has been discussed previously, albeit, I cannot find where. I have a DualDisc that I am attempting to rip using DVD Audio Extractor. There are two audio tracks on the DVD. One is 82.2 kHz, 24-bit, 6 channel and the other is 82.2 kHz, 16-bit, 2 channel. I am ripping to WAV and am only concerned about stereo. Ideally I would like to have the higher bit rate (24-bit) from surround title. Therefore the question is, what information am I losing if I rip the 82.2 kHz, 24-bit, 6 channel title to 82.2 kHz, 24-bit, stereo?

Thanks!!

That's an awfully vague question. If I said that what you are losing is four channels, would that satisfy you?

The question you should be asking is, between 24 bit 88.2 (not 82.2) kHz and 16 bit 88.2 kHz, what would I be losing? The answer to this question is, essentially nothing.

If you then asked what you would lose between 88.2 kHz and 44.1 kHz, the answer again would be, essentially nothing.

Essentially the question was with the intention of a stereo audio file from the DVD at the highest possible quality, would it be better to rip the 16-bit 2.1 track or the 24-bit 6.1 track as stereo. To my understanding it seems as if it would be best to rip the 24-bit track as stereo, that makes the most sense. That is unless I am overlooking something...

And yes, 88.2...my dyslexia kicked in there for a second.

If you rip the 6.1 to stereo then all the discreet channels should mix down to the 2 discreet stereo channels. What you will lose is spatial information. If the track is provided as a 16 bit stereo track then the question you need to ask is who does a better job of mixing the channels, your ripping software or the mastering engineer who already did it for you.

As to the question of if you need the 24-bit resolution over 16 bit, unless you're going to be doing further mixing and mastering using that track the answer is no. The only thing you gain with 24-bit resolution is a bloated file size with no audible difference.
