A higher sampling rate will capture a larger frequency range, but it won't improve the sound quality within that range.

The interpolation you mention is called quantization error, caused by having to use discrete steps rather than an infinitely analog level. Quantization error effects the maximum dynamic range of the recording. A 16-bit CD has a dynamic range of 96dB vs about 70dB for vinyl.

Analog media does have it's own "data points" as well. The size of the magnetic particles on tape or the size of vinyl that is required to still be strong enough to not break when in contact with the stylus. It's harder to measure but it's there.

Regarding compression, CDs do not use lossy compression whereas DVDs use MPEG2 lossy compression.

Do you know if it tends to be more or less information than a digital transfer of the same material on CD?

Half-baked thought: I wonder if there is any audible characteristic to regularity/irregularity of information density on a media. Like I assume CDs would be very regular, where as tape may actually be inconsistent in this respect.

Sorry, intended to agree with you about CDs/DVDs using compression/not using compression. Edited my previous post to fix the typo.

In terms of capture, missing a frequency range sounds like it compromises 'fidelity' in some audible sense if those ranges are indeed audible--all of this as compared with analog media.

Simply asked: Is it possible that someone could hear and prefer/dislike the sound of audio recorded at above the threshold described by the nyquist theorem?
