dB Waves

I haven't seen this posted in a dog's age.

Kill the blue wave Percent Scale.

This one's practically a "gimme." Simple graphic change with straightforward, apparent benefits. I'm sure there are dependencies here and there, but compared to the current crop of Audacity problems, this should be a stroll in the park. Something that could be tackled, say, before lunch.

I do not like working in Waveform (dB) because most important sound management (except noise) happens in the top 24dB. Perfect for linear waves.

That's only the top of the waveform.

In case you missed the conversion, Audiobook readers need to set their recording peaks between 50% and 34%.

The fake graphic only has the positive-going waves because I wasn't up to Photoshopping all the values between the two zero points. That and I think -24 is actually in the wrong place. It's a free-hand illustration.

I did discover one dependency. Generate > Tone is in Percent. Others may be, too.

"Make a -20dB tone."
"Sure. Let's see. Divide by Log 10..... No, wait. Divide by 20 ...."
