a77387b549 Avoid taking the square-root of the ambient gain 
Although it is more correct for preserving the apparent volume, the ambisonics-
based panning does not work on the same power scale, making it louder by
comparison.

ea0aea6508 Change the autowah to have a cutoff range of 20Hz to 20KHz 
This is the same as allowed in the SF2 spec for its filter cutoff generator,
which can be used for a wah effect in MIDI. It makes sense to use a similar
range here.

d596cf9cf3 Use a different autowah filter range 
Still just guesses, but this seems to avoid math problems with low peak gains.

d6eff654be Redo the autowah effect 
It's now a low-pass filter with a cutoff that varies according to the input
signal amplitude.

There remains issues with apparent feedback in the resonant frequency with high
resonance values. The actual cutoff range for the filter is also a guess.

48aa1e10d6 Use the high-shelf filter in place of low-pass 
They effectively both work to lower (or raise) high frequencies. However, the
high-shelf performs better when gain=1.
