4 BAND COMPRESSOR FILTER CALCULATIONS ADAU1450
Subscribe
I am working on a 4 band compressor controlled from a micro-controller. The problem I am running into is the crossover filter calculations. The filter type are all set to 24 dB Lingwitz-Riley in SigmaStudio, which I assumed were standard cascaded 2nd order Butterworth crossovers. The parameters for the low and high filters and mid low and mid high filters appear to be that However, there are parameters for OVERLAP LOW, OVERLAP HIGH, OVERLAP MID LOW , OVERLAP MID HIGH and ALL PASS, that are confusing.
Can anyone from Analog Devices. shed light on this?
