Audio editing can seem a bit daunting when you’ve never done it. I remember when I got started how it all seemed so foreign.
If you’ve never edited an audio file before, I recommend that you try getting your feet wet using the free audio editor that millions of other folks are using, called Audacity. Audacity has been around for around 20 years (it seems — I used it in the 90’s). It’s not the most advanced software out there, but it’s free and it’s so good that my friends at our Christian Radio station do lots of their voice editing using it — and their stuff sounds GREAT!
