Reply To: Width range in PEQ

Unfortunately it’s far from a simple formula. See https://www.sengpielaudio.com/calculator-bandwidth.htm

However, learning a few of the figures from the little table near the bottom of that page may help you do what you want.

For what it’s worth, a q of 5.5 would be around 1/4 of an octave.

Edit – I obviously type too slow!
