Using all that CD has to offer?, What types of music and specific discs use the full bits and freq.

(i'm probably oversimplifying this in my ignorance about it)

Dynamic range of analogue vs digital cannot be compared so easily either - the former can provide subjectively useable dynamic range which exceeds that of its digital equivalent, because it 'fails gracefully' above its rated maximum range, continuing to capture information which, in the digital domain, would have simply been truncated (resulting in a clipped waveform).

You're looking at the wrong end. Where is the noise floor? As a delivery format 16 bits is sufficient in storing this information. With the vast majority of the music out there and especially from the artists referenced in this discussion this can be done with fewer than 16 bits.


This got me wondering what styles of music generally do use the full bandwidth and bit-width available on CDs? The bits provide the dynamic range, yes? So classical would be more likely to take advantage of all 16 bits than rock recordings? What about frequency response? What types of music are likely to span that 18.5hz - 22.5khz range? Electronic? Classical again?

Anyone have an specific discs that utilize all the bandwidth and bits that CD has to offer?

As an aside, i do remember reading a subwoofer shootout in some magazine where they measured some CDs as going down to 16hz. Doesn't that go below the limits of CDs? Were they probably just listening to reflections?

Thanks

I bought this one new a few years ago, and it seems they are still selling the same 1983 CD issue. (Same, btw, for Alphaville's Forever Young from '84, another one that needs a remaster job about as much as a hole in the ... err ... reflecting layer.) At least my CD posts the same results as found in the DR Database, i.e. DR15. Sounds quite nice, if a touch bland maybe (showing its age). I might be more fond of it if I could make out what she's singing more consistently.

Looking at the tracks in Audacity, I can't find any passages remotely close to -70 dBFS though... -50 dBFS is about it.

I actually have both CD issues of Peter Gabriel #4. The remastered version has a far more informative booklet, and some might prefer its somewhat different sonic balance - but ultimately there was little to gain from a digitally mixed master, and some dynamic range to lose at the top. The loudest drum hits at the very end of The rhythm of the heat come out audibly clipped. That, IMO, is not acceptable.
