I would like to know if anyone can help me design a circuit that uses op-amps or any other kind of amplifier to take an audio signal from the left speaker and mix it with the right speaker. I have made a small one, but it's hard to calculate what the resistor value needs to be to control gain in the op-amps.
What I would like specifically is to have the audio come in and get mixed so that the signal could be sent out to a VU meter. ex: if there is a lot of music or what not in the left speaker, then the left VU meter would be higher than the right VU meter and vice verse.
The circuit I have posted, is the simple one that I made, I just can't seem to find a consistency between the gain resistors in the op-amp and the Audio level that is put in.
