It would need to turn down a gain control slightly once a threshold level was reached, wait a set time, then gradually increase the gain again.

I imagine one could use the avg~ object to keep an eye on the level but I’m not quite sure about the rest.

Helpful thoughts much appreciated.

Thanks
Will

Check out the thresh~ object, for starters.

make a tapping delay with feedback, put the feedback
value on 0.999998, then put a limiter in the feedback path.
