VoiceMax
 

Appears to be another rehash of a common AGC controller amplifier
circuit with way too much preamplifier gain parked in front.

And you claim it can keep a 100 modulation level with zero output
level overshoot? Why you've done what audio engineers have been
trying to do for decades.

:-)

Anything special about this circuit we should know about or is it
just another common audio agc circuit like the many we've seen
in magazines through the years? Doesn't have anything special going
on to to know the difference in unwanted background noise/audio does
it?

curious minds would like to know...

cheers,
s.

Good to hear from you Skipp. You're right... every AGC circuit has
overshoot. The overshoot on VoiceMax has a duration of about 1mS
using
the Analog devices SSM2166. You can see the complete specs of this
chip at http://www.analog.com/UploadedFiles/...ts/SSM2166.pdf
