Free Tools- LAME for Audacity

LAME is a library that allows some programs to encode MP3 files. LAME is free, but in some countries you may need to pay a license fee in order to legally encode MP3 files. Audacity is a free and open source Audio Editor which allows you to convert ogg to mp3, convert mp3 to ogg, convert vinyls to mp3 or ogg, do any kind of home recording, remove noise, etc.

  To use LAME (or FFmpeg) with Audacity, you can put it anywhere you wantand Audacity will ask you for the location of this file, so you will want to remember where you put it.
