No we haven’t.
For FIR filters, their software does the crossover FIR filter design for you from measurements, unless you select “custom” – see section 2.2.2 of their documentation. They don’t provide any information about loading a “custom” filter, but it’s likely it’s just a TXT file of coefficients, which our software can export.
For the IIR filter EQ, like I said above, we need to know the specific math they use so that we can make a “Four audio” IIR mode in our software. If you already have FourAudio products, I suggest you contact FourAudio and ask them to contact us. We’d be happy to implement their filters, but we need the math. See “IIR filter emulation” on https://eclipseaudio.com/brand-integration/
