I am creating a project where I am taking A/V inputs from a DVD player, laptop, insert other a/v device and outputting an analog signal (HDMI in the future) where the audio is at a constant level between input devices.
I figure that this would simply consist of some sort of volume control that bases its volume off of the output from a peak detection circuit with two voltage match circuits (one for over the threshold, one for under) to keep the peak volume even at 100db. I would like to keep everything in analog so its faster and wouldn't rely on programming but its not a requirement.
Of course I could also use a DSP or microcontroller but i'm not sure if the delay would offset the sound to the point where the lips are not syncing correctly.
Does anyone have any suggestions on how to complete such a circuit? I would prefer to use TI parts, but i'm up for just about anything to get me started.
