The Loudspeaker And Room System Analyzer, (LARSA) now has an option for performing sophisticated DSP filter design and editing.

You can select from a variety of filter setups, for different hardware devices.

Start by letting the software design a set of filters for you, check the predicted response, and then edit the filters to get exactly the response that you need. When you are done, you can export the filter parameters and the DSP biquad filter coefficients to import them into your hardware.
