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.
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 2. Click “File” > “Import” > “Audio…” or press Ctrl + Shift + I on the keyboard to open the "Import audio" dialog box
Step 3. Locate the Mp3 file on your computer and double click it, it will import the file automatically and create a new "region" in the Audacity timeline
Step 4. Press the spacebar to start and stop audio playback
You can also use the "transport controls" in the top left corner of the window.
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
Step 6. Click “Edit” to use most of the other functions like “Split Delete”, “Join”, “Duplicate”, and “Silence Audio”
Step 7. Experiment with these and other functions on the toolbar to perform similar editing tasks
- Click the “Trim” button to keep only the selected part and delete the rest of the audio.
- Click the “Silence” button to stop playing the selected part of the audio without also removing it from the timeline.
Step 8. Add effects to your audio file by clicking the “Effect” menu and then one of the effects from the submenu such as “Change Pitch”
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.
