LAME lets programs encode MP3 files. In some countries you may need to pay a license fee to legally encode MP3 files.
Audacity is a free, open source audio editor for recording, converting, noise removal, and more. I’ve used it for years; check out my music.
When you first export MP3 in Audacity, you’ll be asked to locate the LAME/FFmpeg libraries. Remember where you place them.
