There's an article about the Noise Reduction algorithm on the Audacity wiki: https://wiki.audacityteam.org/wiki/How_Audacity_Noise_Reduction_Works Note that this article is quite old, and is about an older version of the Noise Reduction effect, so some details may be slightly different, but the basi...

The only "controller track" that Audacity has (at present) is the "Time Track".
For changing pitch without changing the speed, Audacity has two effects:

No, Audacity doesn't have that feature. You would need to add a command to set the cursor position. Note that normal batch processing acts on the entire file. To apply an edit / effect on just part of the files, you need to use commands to "select" the appropriate part - see the "Fade...

Depending on you Desktop environment, you may find some of the suggestions in this article helpful: https://www.addictivetips.com/ubuntu-linux-tips/enable-hidpi-scaling-on-linux/ (Personally I use XFCE, but my display is a relatively modest 1920x1080, so while some of the fonts are a bit small, it i...

All it does for me is open up Audacity with no pop up window with permission to access microphone. For me, the pop-up appeared when I clicked the record button for the first time. After that, I still need to launch Audacity from a Terminal window, but there's no more prompting for access to the mic...

If you need sound / Silence finder to be sample accurate, it would be relatively easy to modify the plug-ins so that the process every sample instead of blocks. These plug-ins are just plain text files, so it's quite possible for anyone to make the necessary modifications - no need for "compili...

You should hear the difference in 20-20000 range How do you know that the "difference" isn't due to Noise Reduction working better at the lower sample rate? The reason why this is probably the case, is that the frequency band of the noise profile are much narrower (more specific) at lower...

Sound / Silence finder plug-ins are not sample accurate. They analyze the audio in small blocks rather than sample by sample. This is because they are "Nyquist plug-ins" and for Nyquist, looping through every sample would be rather slow whereas looping through the selection is small blocks...

I've just noticed a bug!
The filter has positive gain. This means that it amplifies sound in the pass-band.

Fix to follow.

Audacity 2.3.3 is a 64-bit app. It requires a 64-bit version of macOS.
