"Transport" menu. Turn off "Software Playthrough".

It depends what the pop-up messages are.
The pop-up asking for metadata prior to export can be disabled in Preferences:
"Edit menu > Preferences > Import / Export -> Show Metadata Tags editor before export"

Maybe the forum's admin needs to disable a few old and insecure encryption protocols? The forum, and the other Audacity websites, use highly secure, professional SSL authentication across the board whenever "https://" is used as the web address. So as to avoid breaking compatibility, the ...

This isn't a known issue. Which exact three-section version of Audacity are you using (look in: "Help menu > About Audacity"). Which Audacity " theme " are you using? Do you see an "i-beam" cursor in other applications (such as when over normal text in your web browser)...

If you mean that you want to remove quiet sounds that occur at the exact same time as louder sounds, that may not be possible.
What sort of "noise" do you want to remove?

So the question is: which file is compressed LOSSLESS and which one is LOSSY? Both are lossy. If you want lossless, I'd recommend sticking with 16-bit WAV (compatible with everything), 24-bit WAV (all studios should be able to support this, but 50% bigger than 16-bit, and rather over the top for sp...
