Hello,
I want to convert my equalizer from Equalizer APO to a biquads file to move the equalizer from Equalizer APO to my miniDSP.
I'd like to convert this (-20 db at 10hz, etc.):
10 -20
15 -8
20 0
to a biquads file.
Is there some plugin or tool to do this?
Are those values taken from GraphicEQ?
miniDSP supports FIR filters so, you have the coefficients there already. You need some math to convert the dB to linear https://www.redcrab-software.com/en/Calculator/Electrics/Decibel-Factor and then find coefficient locations https://docs.minidsp.com/product-manuals/2x4-hd/dsp-reference/fir-filtering.html#fir-filtering-overview in manual input on miniDSP control software.
Alternatively, EqualizeAPO package's Benchmark utility saves your active EQ to an impulse file which can then be loaded to a convolver (FIR). miniDSP seem to support up to 4096 taps size files so, check if the file generated by Benchmark fits in this requirement.
