[sdiy] What is filter squelch?

[Johannes Öberg]

So there's nothing going on like gating/squelching the resonance feedback?

In a lot of soft synthesizers, especially old 303-like ones, there's a 
control for squelch or similiar, which makes the filter more squelchy, and 
sound more like a 303 (to my ears). What do these generally do? Do they clip 
the feedback, make the cutoff envelope affect the q, or something entirely 
different?
