Re: Determine decibel levels at different frequencies.

All right...how about this attempt at getting it?! First, Steve, are you saying that the spectrum "curve" as it appears, is actually upside down, so to speak, so if I wanted to calculate the "area under the curve" I would determine the area of the white portion and not the blue portion? I notice tha...

Re: Determine decibel levels at different frequencies.

I thought I was on the right track when I pulled down the "Plot" option -- now, is there a way to enter a "zero" number/tone, and/or a "reference" into the data, so that I can see a "positive" spectrum? Is there a way to overlay the reference with the new sound so that I can see the net difference? ...

Determine decibel levels at different frequencies.

I have Windows XP, and installed 2.0 from the .exe installer...

I am trying to use Audacity for a different purpose -- to determine decibel levels of recorded sounds at 8000 and 16,000 Hz. Can you teach me how to click my way to these determinations for my recordings?

Thanks, Lou Duckwall
