Yeah it will be very reactive until it’s warmed up, so this is more of a live input thing as it is in the picture. Would maybe want to record and lock in ranges before packaging, if there won’t be any surprises regarding what is played through it.
Outside the picture there is smoothening via interpolation going on, and also a ‘forgetful memory’ function that will calm down the max recorded values over time(without this, a single extreme volume event could ruin the long term normalizing).
