ADAU1761 volume control
hello
I'm looking for a volume control where the change happen with a costant db/s slew.
The algorithm for volume control in help file is not avaiable for the adau1761,
anyone has a suggestion how to implement this kind of algorithm?

Hi Stephano:
I thought we had this volume control, but I can't find it somehow now. To do this graphically, you need to compare first see if you are going up or down. Use the conditional block to make the comparison. If your value is Zero, then set your starting point at very low value and use a multiplier (above 1) with some feedback to increment your current volume logarithmically. If your value is 1, things are easier. You simply need multiply your current volume by a multiplier (below 1) until you reach Zero (or a minimum value).
Let me know if this is clear.

Hi stephano
This block will be available next week in a new SigmaStudio release.
