adau 1772

Hello everyone!

we are currently designing a new product, based on ADAU 1772 audio processor.
We need to measure RMS value of the signal for at least 0.05s. We trued the Single Level Detector (SigmaStudio 3.11), but it seems that it calculates (and returns to DBREG0-DBREG2) a value calculated for the shorter time. Could you share, please, more information about the underlying algorithm (how the RMS is being calculated, how many samples does it take, which value it sends to DBREG0, etc). Also we would be grateful if you include some other algorithms for RMS estimation for the ADAU 1772.

Thanks in advance,
