I don't remember if the Normalization effect defaults to 0dB or near 0dB

It defaults to -1 dB (as shown here: https://manual.audacityteam.org/man/normalize.html), which provides just a tiny bit of headroom for safety.

To measure "sound pressure level", you need an SPL meter (Sound Pressure Level): https://en.wikipedia.org/wiki/Sound_level_meter
You can get a cheap one from ebay for under $20, but an SPL meter that is accurate for low level noise isn't cheap (often costing hundreds or thousands of $)

"dB" is a "ratio", not a "unit". Unlike units such as grams, or seconds, or miles, a "dB" is not a fixed quantity, but the ratio of one quantity compared to another. "dB" is meaningless without a reference point. When dealing with audio signals, it i...

Which version of Audacity are you using? (Look in "Audacity menu > About Audacity")
What web page does it go to?

It's a bug in iTunes. Which version are you using?

I've discovered some peculiarities in the behaviour of mod-script-pipe in recent versions of Audacity, but I'm not able to progress further diagnosing the problem that you describe Gibbz without further information about what you are using and what you are doing.

Is Audacity merely trying to make it "easier" for its users? This isn't due to anything that Audacity is doing. It's a "feature" of the sound card drivers. because Adobe Audition is not performing this way with all the same settings Audition is most probably using different driv...

You type 100 and it adjusts 100, 200, 300, 400, etc right up to the sample rate, So that is adding 100 on each loop, where "fc = 100". (do* ((hz fc (+ hz fc)) I wonder if it's possible to adjust in this case: 100, 300, 500, 700, etc, skipping the even order harmonics. and that is adding 2...
