The ERB equation can be inverted to solve for filter center frequency.

Evidence

To find the center frequency of the auditory filter whose critical bandwidth or ERB is equal to a given value, the ERB equation (Equation 2.6), which relates the critical bandwidth to the center frequency of the filter (fc), can be rearranged as follows. — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 2798
