So, I know that fact that UHQ audio is 32bits and 96khz. Can humans or anything for that matter, hear THAT high?

Fangirl96 kHz refers to the sample rate. You can think of this as the "frames per second" of audio i.e. how many times a second the audio is refreshed. The bitrate refers to how many levels of amplitude there are i.e. loudness. You're right in saying we can't hear frequencies above 20 kHz.

tylerp96 kHz playback will allow the accurate playback for frequencies up to 48 kHz due to the Nyquist-Shannon Theorem. https://en.wikipedia.org/wiki/Nyquist%E2%80%93Shannon_sampling_theorem . Most say this is not necessary because of the limits on human hearing, but there are some arguments for having that extra frequency headroom (mostly in the way overtones react with each other). Tyler is correct on the bitrate! A higher bitrate gives a recording more precise amplitude playback.

MichaelAbel289I will confirm that overtones even out of the human hearing range can have a noticeable effect on the sound in our hearing range. To what extent in recorded music is what peaple love to debate.
