Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

How to cancel out room noise when speaking?
My favourite free denoiser for room noise https://github.com/nbickford/REAPERDenoiser . Combined with a gate for voiceover can be v effective.
- is it normal for a condenser to make this much background noise. gain is cranked pretty high. focusrite Scarlett and se2200

I know this is a stupid easily solved question
https://github.com/Nbickford/REAPERDenoiser says hold my pint. As good as RX in many cases.

Trying to use voice-denoise to remove background room noise
The best denoiser results require you to sample just the hiss by itself. They then try to remove that noise from the recording. The RX one has a setting for this. This free one from Neil Bickford also does a fantastic job , far better than ReaFIR subtract https://github.com/nbickford/REAPERDenoiser

Noise Reduction glitches
Try this instead. Far better denoiser than ReaFIR. Simple to use too. https://github.com/nbickford/REAPERDenoiser

Isolate a certain sound from a noisy video? Description in comments
I don't think you can get a really good result, the sounds overlap in the frequency spectrum too much. This is the best free denoiser I know. Far better than ReaFIR and can sometimes be better than RX. Worth a try. V easy to use. https://github.com/Nbickford/REAPERDenoiser

ReaFIR question
The best free denoiser I've come across is a JSFX one coded by computer scientist Neil Bickford. It's easy to use and often gives better results than commercial ones, like RX9. Far better than ReaFIR for this. https://github.com/nbickford/REAPERDenoiser

Audacity 3.4 – New Musical Features
The time stretch algorithm is implemented in https://github.com/audacity/audacity/blob/master/libraries/l... particularly functions _time_stretch and _process_hop. It looks to me like a classic phase vocoder with vertical phase coherence (c.f. https://en.wikipedia.org/wiki/Phase_vocoder).
The basic idea is this. For a time-stretch factor of, say, 2x, the frequency spectrum of the stretched output at 2 sec should be the same as the frequency spectrum of the unstretched input at 1 sec. The naive algorithm therefore takes a short section of signal at 1s, translates it to 2s and adds it to the result. Unfortunately, this method generates all sorts of unwanted artifacts.
Imagine a pure sine wave. Now take 2 short sections of the wave from 2 random times, overlap them, and add them together. What happens? Well, it depends on the phase of each section. If the sections are out of phase, they cancel on the overlap; if in phase, they constructively interfere.
The phase vocoder is all about overlapping and adding sections together so that the phases of all the different sine waves in the sections line up. Thus, in any phase vocoder algorithm, you will see code that searches for peaks in the spectrum (see _time_stretch code). Each peak is an assumed sine wave, and corresponding peaks in adjacent frames should have their phases match.

If you are able to build from source, you could download the latest source code, or the latest release version source code, and manually apply the patch.

Custom Themes for 3.1+?
FWIW: We'll be ditching the atlases for 3.4 most likely, in favor of having themes work like they do in source anyway: With individual PNGs for the icons and a Colors.txt containing all the color definitions. With that, custom themes would be much easier to author and also would stop breaking every time we introduce a new icon.

Audacity 3.3.1 on Tumbleweed is freaking out
https://github.com/audacity/audacity/issues/4639 this bug mentions everything, I guess it's Audacity after all. To be fixed in 3.3.2
- Tumbleweed, most Audacity "Generate" functions are broken

One-click monitoring in Audacity 3.3.1?
No there isn't. I searched in vain for a workaround, and then checked the Audacity issues and found this: https://github.com/audacity/audacity/issues/3385
