Hello from Penn's woods.
I and others are annoyed by the "background" music in videos particular
in documentary videos like Nature, Nova, and others on Amazon prime. Often the
music competes with the narrator and when there is no narration it blast out at you.
With that in mind a put together an active low pass filter using a dual audio op amp
that helps somewhat. I am thinking it would be helpful to have a circuit that limits
the music volume as it rises.
I found an interesting circuit that uses the nonlinear transfer function of diodes.
I have to admit that I am confused by the plot of input versus output and what is voltage
"with clamping" As the output exceeds the input I gather the output is from the
MAX9700A at the speakers?
the circuit is here: https://www.maximintegrated.com/en/app-notes/index.mvp/id/4551
Example of a loud video:
thanks.
