I'm interested in building an automatic volume control for my TV.

What I want is a device that I can splice into the leads leading
to the speaker.  It should have only 1 external componenet being
a pot.  The device should increase the volume if its a wisper and
decrease the volume if its a roar.

Does anyone know if a beast like this already exists?

Can anyone give me some pointers?

PS. I was wondering how to take apart an old cassette recorder
    that has its auto volume control already on its microphone
    input and hook this up.....BUT then there's the difference
    in signal amplitude.
