This does NOT sound like RAW audio.
It sounds like they removed the lower and upper bands of "near hearing" (similar to MP3 compression, except removing sounds that people can normally hear as well). Then converted to 8-bit resolution (the dull and incomplete sounds). It distinctly sounds as if it is missing most of the waveform.
Now, graphics whores are one thing. They're insisting developers spend REAL MONEY to implement small changes to "visual effects" and no changes to gameplay. In many ways, focusing so strongly on visuals can reduce what you can achieve (financially or hardware-limitations.)
This... MINOR... Audiophiling? We're insisting that developers add on an extra 100mb's, costing (at say, $1 per gigabyte) an extra 10 cents to them. It can even save them money as they don't have to spend all the time butchering the original sounds! Win-Win!
Of course, asking for RAW audio would be absurd (notes on the additional 1GB for voices)... but they're butchering Christopher Loyd!!! At least give him 22.5Hz -16bit... it's Christopher LOYD!!! He deserves it
/me wants a HD Audio Pack!
Do note, I already own the games and am NOT regretting the decision to purchase.
I'm just... disappointed, shall we say... that they would do such a horrible thing when they have so much dialogue. *and again, on the note of people who like to troll. This is rather severe audio-butchering, even for early dos games with only small amounts of spoken dialogue. (And THEY, at least, had hardware, diskspace, # of floppy's needed, to consider).
Console games may have been worse due to hardware limitations... but there really isn't a good supporting reason as to why they needed to reduce audio samples down to 22.7 MB.
It's just... a major disappointment.
