Seems nearly impossible to find great AU freeware, so i thought we could share anything we've found. Personally i'm having the most trouble finding formant/vowel filters, as most seem to be put inside instruments. I'm currently using the WOW demo and having to bounce the midi down as audio before the timer runs out. Very annoying as i obviously can't go back to adjust anything once converted.
I'll get the ball rolling.

Both are worth downloading, but the 'Freeware bundle' is what i often use. I recommend using these two together to create pretty nasty basslines.
+chebyshev
a distortion unit which uses various low-order chebyshev polynomials to add even or odd harmonic distortion.
+decimate
bit depth and sample rate reduction for added aliasing and decimation noise. a very noisy plugin.
Share the wealth!
