Here's another though if you don't mind using a buffer. I saw a simple
little op-amp circuit in the electronic book I am reading right now that
outputs a positive voltage equal to the incoming voltage (negative or
positive). So essential, it returns the "real" number. I was thinking
that would be an idea way to read CV on normal a 0-15VDC meter. The meter
would be protected from incorrect polarity. A couple of LEDs (here we go
again) could be added to indicate whether the voltage was negative or
positive.
I hadn't though too much about how to look at AC. But, as I think about
this circuit it would seem to provide a rectified version of any audio.
Some deflection is going to occur, but obviously not a peak value. Hmmm...
something else to play with and learn.
