"Amplify" is limited to +/- 50 dB
I can certify it won't do -60. I also have evidence of it acting oddly. Generate Noise at 0.3 amplitude, Amplify it -40dB and rejoice in a -20dB noise track.

This has not gone well.

Rather than beat this up at great length, I'm going to do all the editing except the front, compress and then cut it off. Same labor, different order.

Because amplify doesn't allow changes by more than 50 dB. You have to "amplify" trice to get under -100 dB.

By the way, a nice radio show, very entertaining although I'm not automobilophile.

a nice radio show
It was. They went their several decades of production and then stopped. One of them died. The shows are now "Classic Car Talk" repeats.
I'm not automobilophile.
The cars are almost completely beside the point. I don't think they accept callers unless they also have marital or other problems.

"I think there's a raccoon living in the trunk of my car. No, no. He's fine there, I want to know if I should tell my husband."

That caller appeared in the "third half" of the show.

And etc.

The history of the show has one of them doing a tiny, local car call-in program and he got in over his head and asked his brother to stop by briefly to help out. It was one of those magic broadcast marriages.

They are characters in several movies.

It works for me. 0.3 is -10.458 dB.

Amplify by -40 dB. New Peak Amplitude shows -50.4576 dB.

Apply Amplify and reopen it. Amplify shows the amplitude as -50.4576 dB (Amplification of 50 dB giving New Peak Amplitude of -0.4576).

It works for me.
And that's the magic. It's possible it only does that at the beginning of my Car Talk Project. I need to set it up again and get repeatable conditions.

For a while there I had a poisoned magic wand. Everything I tried either failed or did something unexpected and not useful.
