A good audible demo of the linearizing effect of dither

[[email protected]]

The demo is 8 bits so the effect of quantization distortion is much worse compared to what 16 or more bits would sound like.

Note that dither does not simply MASK the quantizing distortion with noise, it ACTUALLY linearizes the conversion.

Quantizing noise is a misnomer, it is more correct to call it quantizing distortion.

Thank you, this was interesting to me. Dithering is a subject I don't
understand very well, and this helped a lot.

Part of the Monty Montgomery link I put up addresses this in a very easy
to understand way. he even shows how dither causes signals below the
noise floor are recoverable w/ dither.

Thanks, I'll check that out, too. The math and physics behind it are
beyond me, but these help me get a handle on the practical aspects.

I doubt that. The notation will sure get in the way, though.
