I downloaded an album from Bandcamp and it’s a zip file. When I open up the zip file, the individual song I need won’t upload into Audacity. How can I import a singular mp3 file from a zip into Audacity?
Audacity can’t decompress a ZIP file.
Did you un-zip it? If not, right-click (with Windows Explorer) and select “Extract All”. (If you don’t see that option, you may have an older version of Windows and you may need an un-zip utility.)
Windows has had the ability to unzip for 20 years … https://wikipedia.org/wiki/Zip_(file_format)#Implementation
