Automatic Loudspeaker Equalization

Other Parts Discussed in Thread: TAS3103

I'm playing with old TI ALE 3.2 program and I would be interested what kind of algorithm is implemented there to design / calculate biquads (peak filters) and their parameters (frequency, dB gain and Q) . I mean what kind of optimization algorith is used to set these parameters to fit to measured raw response to minimize the frequency reposnse error. There are at least 3 degrees of freedom (frequency, dB gain and Q, maybe filter type as well) and I'm thinking how to optimize these parameters in my own application.

Thank you.
