stupid envelope follower idea

[Martin Czech]

Envelope followers all suffer from the ripple/speed tradeoff.
Very low low pass filtering of the rectified output gives low
ripple but also slugish response and vice versa.

Now, could it be improved via modulation techniques?

I mean if I modulate the audio with some sine carrier,
it would at least cut down the low frequency sideband by 1/2.
If that is rectified and filtered, I think it would perform better.
Like AM demodulation, well almost, but without carrier
feedtrough.

When I think it to the end, it comes close to PCM sampling.
If I were to determine the envelope with pencil and paper,
I'd try to connect the peaks with straight lines as first order
approach.
