The concept of dither is totally independent of the underlying waveform. In sinple terms it is injecting a random element into the LSB. What is in the other bits makes no difference.
Of course we do listen to sine waves - everything we hear is a very large number of sine waves occurring simultaneously :-) It's just maths; the "maths" don't know the difference between pure sine waves and anything else. Also, some noise is ALWAYS present in real recording, so dither does not need to be added, the inherent noise acts as the dither signal. If you are looking at computer-generated sine waves, artificial dither needs to be added. Finally, what is shown in Figure 3 (blue trace) is quantization noise peaking at -110dB. (for a -70dB signal). So, the spurious noise is 40dB BELOW -70dB!!! -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
