I need a hardware volume leveller/normalizer for analog audio from cable box to tv. (schematic or product)? Answered
Searching around I've found several shareware software programs - installing an extra computer for this task isn't an option. Ibles doesnt seem to have anything like this... I'm thinking an arduino, a sneaky sketch, and an lm-series stereo volume regulator. All the hardware I've seen dies a quick death - presumably the way of the electric car - too much lobbying from advertising industry to stop them hitting store shelves. Frankly, I think its beyond un-ethical. In my particular situation, its potentially dangerous.
