Editing an Mp3: 9 Steps (with Pictures)

Mp3 is an audio encoding format used as a standard for digital audio compression and is the most common file format for playing and storing audio files on common media players. MP3 files can be easily modified using audio file editing software such as encoding or decoding, creating mixtapes, trimming or fading a song, and normalizing volume levels. This article will walk you through the whole process of using audio editing software so that you can edit an Mp3 file yourself.


Edit an MP3 File Step 1

Step 1. Download an audio editor

Free open source software like Audacity is a good choice for this example. Most other audio editors and DAWs have the same capabilities for editing Mp3 files.

  • Go to the Audacity download page and click on the operating system of your choice. The latest Beta release is usually easy to use, but it is also possible to choose the most stable and tested version. Use the Beta version for the latest operating systems such as Windows 8, 7 and Mac OS X 10.6.
  • Double-click the Audacity installer you downloaded and follow the installation instructions.

Step 5. To select a specific part of the audio file, click and drag the mouse from the beginning to the end of the audio part you want to save in the timeline

This selects a portion of the audio to edit.

Click the scissors in the toolbar to “cut” or remove the audio portion from your selection. This method can be used, among other things, to remove parts of the music, reducing the length of the audio file

Edit an MP3 File Step 9

Step 9. Click on “File” and then on the option “Export” or “Export selection” to be able to export your edited file from Audacity

Note that “Export” will export the entire audio file from the Audacity timeline. “Export selection” only exports the current audio selection. Both options may be useful, depending on the type of edit you've applied. NOTE – Until you have purchased the software, you can only save the edited file in the.wav format. For saving as an.mp3 file you will have to look for free tools, which are available everywhere.
