Hello Eclipse Audio,

we are using your software to design correction filters based on measurements for a speaker project.
At the moment we are testing your IIR filter implementation ‘Generic’ and we’re curios on which your IIR models are based on –
Is it possible to send us some information about the filter types you use for the ‘generic’ model?

Aside from that, there are IIR model options of several manufactures choose-able in FIRDesigner –
is it possible to provide you certain filter models which would be included into your software and how is the proceeding?

Thank you a lot and kind regards,
Isabelle

The Generic mode uses the Robert Bristow-Johnson methods for parametric, shelf and notch filters, and textbook definitions for other LP and HP filters.

Yes, we could consider implementing a branded IIR filter mode for you. See the information under “IIR filter emulation” on the page
