[PD] any tips on fart synthesis?

Sawtooth modulation (~5-20hz) of the cutoff frequency of a resonant lowpass filter (such as vcf~) and a simple pitch curve (rise fall, fall rise, fall fall, rise rise) on a complex waveform going through the filter. 4-point amplitude envelope - fastish attack, slightly slower decay with an imbalance of maybe 3-6dB between the second and third points. Medium resonance.

Then you stick the whole lot through another filter -  a peak EQ. Some kind of envelope. Maybe something needs to be done with the pitch, in sync with the saw tooth modulation?

did you try to sample what it sounds like? I got similar sounds also 
from recordings in a wash basin using empty plastic bottles or hands, or 
mouth sounds (like trumpet blowing, but under water).
or really try to rebuilt it synthetically, probably two amplitude 
modulated waveshaped signals.
would be nice to see synthetic solutions for it.
