I haven’t updated my IOS nor have I done an Audacity update. Using version 3.7.7. I’m using Noise Reduction for probably the 100,000th time, and suddenly, after I apply the noise reduction, there is zero change in my noise floor. Before applying Noise Reduction, my noise floor is -69.12 dB. After applying, it is still -69.12 dB.
I am selecting about two seconds of noise floor and clicking “get noise profile.” Reduction is set to 19dB, sensitivity is set to 0.01, and frequency smoothing is set to 3. For “noise” I have selected “reduce", not “residue.” After I click “get noise profile,” I select all of my audio, and then hit command+r to redo the noise reduction. A little pop up comes up that says, “Applying noise reduction,” which takes about 5 seconds to process. Then, I check again, and my noise floor is still sitting at -69.12 dB. I am going insane please help lol.
Potential FAQs: yes, I restarted audacity. yes, I restarted my computer. yes, I went into a different .aup3 file and tried all of this again with the exact same results.
As an experiment, apply the Noise Reduction effect with residue enabled, then look at the tracks with spectrogram enabled and see what it’s actually removing, if anything.
If you are selecting all the audio for the noise profile, you are comparing everything against itself. From what you wrote I can’t tell if that is what you meant or not.
Thanks for the idea. I tried applying Noise Reduction with residue enabled, and all of the audio disappeared? Not sure if I’m doing something wrong, I’ve never used the residue setting before.
To clarify, my entire audio is 18mins, I am only selecting 2 seconds of noise floor and using that to “get noise profile,” then selecting all of my audio to apply the noise reduction to all of the noise floor over the course of the 18 minutes.
Update!! I figured out the issue! My sensitivity setting must’ve gotten bumped somehow. I changed it to 6 and it is now working smoothly again. Thanks again for working with me to try and figure it out!
For those who have wondered what the residue setting is, it shows you what audio is being removed. It allows you to play with the settings and see what effect they are having. If you apply noise reduction with residue enabled, the track you are left with is just the removed audio.
There is no Audacity for iOS. iOS is the operating system for iPhones. iPadOS os the operating system for iPads, and macOS is the operating system for Apple’s computers.
Audacity 3.7.7 is - to my knowledge - the latest release available. Audacity 4 is “alpha software”, incomplete and untested, so you should not do anything “productive” with it.
