Looking for clarification on the Compressor coefficients stored in memory
Hi, I am designing with SigmaStudio v4.7 for an ADAU1467 processor. My design is using a Dynamic Processor - RMS - Full Range (-140dB to +40dB) - 1 Channel - RMS (no gain). I will be using a host CPU

Fixed register address at pre-compile stage possible?
Hi, I'm wondering if it is possible to "set" a register address at pre-compile stage. E.g.; When I compile my SigmaStudio program for an ADAU1452, compiler sets the address of a readback register to 0
