I'm looking for a formula to compensate the volume loss, when raising the Q factor of reson~ bandpass filter.

The input signal is noise-like (brushed snare).

Any ideas?
A heuristic formula would be sufficient.

reson-changing-q-with-constant-output-volume

Compare the previous bandwidth to the current bandwidth and that's probably a starting point for a ratio. (Previous:current)

Alternatively, you could use an envelope follower, convert its output to db via atodb~, and apply makeup gain.

The solution was to simply multiply the output signal with the Q factor!

The overall volume is not perfectly constant but good enough for my purposes.
