Why not fade out in a linear way.
Look up the spectral components for a ramp like waveform.
Now multiply those with all the spectral components in your audio.
What a mess, really, you should, as a true audiophool,
NOT use volume controls at all.

What feature of the audio amp will "multiply?"

This is about changing volume, changing volume is AM modulation.
The way you change the volume (linear fade, sine like fade etc),
so the modulating frequency, determines what sidebands are formed.
This is a disaster for the true audiophool, as it is basically a distortion
of the original, so that is why true audiophools have no volume controls.
The first tube sets without volume control will soon be on the market now,
at a small extra cost likely.



Let me rephrase the question... How are "sidebands" going to be generated
in an amplifier that is linear?

Nothing to do with the amp, read the thread.
So, changing the amplitude of a sinewave *by any means* is AM modulation.
And the means in this case is the volume control.

How do you believe changing the volume control differs from adding tremolo
to a piece of music?
