I have a 20-bit Telarc CD, and would like to extract it onto my computer. However, I'm not really sure how to go about this without having the WAV truncated to 16-bit. I only have a 16bit soundcard right now, so it's going to get chopped off anyway, but I just want the original, unaltered music in the file.

Any ideas?

Apogee UV dithering is a special dithering algorithm... I don't see any advantage of this over a good noiseshaping dither that also improves dynamic range at lower frequencies.

It seems more like a special kind of noiseshaping to me:

Another technique, ... is "sub-Nyquist dither". This approach, which has been likened to HF bias in an analog tape recorder, adds dither concentrated as near to the Nyquist limit as possible, rendering it inaudible at standard sample rates such as 44.1 kHz and above.

Apogee UV dithering ... uses as dither signal two bands (U,V?) of noise

QUOTE
... UV22 concentrated the dither signal up around an inaudible 22 kHz in a 44.1 kHz sampling environment, hence part of the name (the other part is a reference to "ultra violet", the idea being that it was higher in frequency than Apogee’s signature purple).
To create a carefully-tailored super-audible dither system, Apogee used an algorithm to generate the dither information, rather than relying on noise shaping.


So UV is just part of a marketing name smile.gif
Anyway it's all about a tool to master 16bit Audio material from 20/24 bit sources.
(Thanks for the link Tigre)
