How to Edit a audio / music / MP3 / Song file

Do you like to edit a portion of a music / audio file like MP3 or want to divide the file into two portions? Do you have a song which is too lengthy to be embedded in your video and want to have only a part of that in your video. Don’t worry, it is too easy to do.

Here is a very easy and quick way to do, with a free music editing software. Let me start with an example. I have an MP3 file below, which is more than 8 minutes in length. But I want only the saxophone music which plays for the first 2 minutes, to embed in one of my videos. So, here is what I did.

The software can be downloaded from the website of Audacity.

1. Go to the link -

2. Click on the download audacity for windows option (select the version you wish)
