Can anyone please explain me how dither is used to reduce the quantization noise? And how Noise shaping works?
Wiki's down because MySQL took an enormous #2 earlier today. (I'm honestly surprised the forum itself is working - props to admins)I don't know if this analogy will help your understanding any, but there is a sort of connection between dither and one time pads in cryptography: in both cases, you're essentially adding random noise to a very non-random signal, in order to mask a signal you don't want predicted in some sense. In cryptography it's the plaintext, in audio, it's the quantization noise.
