Got it - do be sure to check out I04.noisegate.pd, they may have
beaten you to it. Even so we should add attack/release with vectral~
(which is maybe a standard object now?) and offer the patch as an
improvement to the documentation.

Cool!
Tom,
Your approach is really sensible and what I was originally seeking to
do, but it's difficult in Pd without the help of a few externals I
imagine. [vectral~] has ended up working just fine and may open some
doors into other strange manipulations :)
Thanks for being willing to share your
Hi Chuck!
Actually I was working on it tonight. The problem with it is that it
is too harsh and leaves too many artifacts on the signal right now
because the binary [~] from zexy needs to be smoothed out with
attack/release that persists across different blocks in time. What I
tried tonight
that is one hell of a lot of fun to play with.

Very nice. Now one can do instant french filter house with it as well!

what is the advantage of spitting out these values in polar coords?
According to the DSP-Guide it this:

Yes, this is true. For many FFT based effects (like spectral gates),
you don't really need to convert completely to polar (this conversion
can be more expensive than the FFT).
For a spectral gate, just calculate the amplitude from real and imag,

When should you use rectangular notation and when should you use

Addition vs. Multiplication, of course
Addition must be done in rectangular coordinates

which we cannot do in polar coordinates, we have to convert back to rect. coords

I sympathize - what about the fftease package? I don't know anything
about it but it may have something like you described if I remember
