Nyquist-Shannon; The Backbone of Digital Sound

[Dawnshine Wonder 456]

Was the Nyquist Shannon theorem correct on CD audio? yes. Unfortunately audio recordings are not perfect and have to be filtered. This is why oversampling is needed, from what I learned about this by looking this up online, you also have to take into account things like quantization noise. But from what I researched so far, I learned with a sufficiently suppressed noise floor, 96db dynamic range is plenty. Some people claim they can hear above 20khz frequency but that has not been scientifically proven, worse, as we get older, that range of hearing gets reduced. For the finished product, 44.1khz 16bit is spot on, this is why the redbook CD standard has held up. But with content creation, it gets more complicated, and that is best done by professionals, not me.
