What's the best way to "add" together both channels of stereo sound into mono? Answered

I'm making a VU meter and I don't want to replicate my circuit for both the left and right channels of audio.  I'd like to just "add" together both channels so I can view them on the meter together.

You should be able to sum them across a resistor.

Can you elaborate and/or provide a useful link?

The best way is probably a simple op-amp mixer. One chip and a few resistors.
