EXT sets the threshold at which the expander starts to work.
EXS controls the slope of the expander circuit.
EXG sets the amount of negative gain.
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 psychoacoustically 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.

DITH allows you to turn the PONS dither function on or off. If set to OFF, dither
noise is still present, but without noise shaping.
This control allows you to vary the amount of dither gain (with PONS on or off)
added to the signal.
