Hello again peoplez! I have faced such a delicate question: the thing is I have a two sine signal sources, which I mix to a single output, I would like to have an ability to regulate the level of each of them separately. For this reason I use auxiliary ADCs. What I would really like to do is to implement such a function, so that if the combined level of those two sources reaches a certain level, the output switches off say for 1 second (or switches to some other tone generator for 1 second), so that the user could understand that the level is too high and turn the volume of some of the sources down. Is there any way to implement that? I tried different ideas but haven't come up with something acceptable. Any help would be so much appreciated!!
