PONS
GeneralDescription
Dither is a low-level pseudo-random signal which is added to digital audio to reduce
quantization noise, in effect, by replacing it with a "nicer sounding" noise. It is possible to filter
the quantization noise in such a way that almost all of the noise within the frequency range
where human hearing is most acute is shifted to higher frequencies. This is called psychoacous-
tically optimized noise shaping (PONS) because it takes advantage of the variations in the ear's
sensitivity to noise within the 20 Hz - 20 kHz range.
