How to Crop MP3 on Windows/Mac

Learning some basic audio editing tips is necessary if you want to make a high-quality audiobook, podcast, music album, or some other audio project. An impressive and engaging audio work can greatly improve the listener's experience and grow your audience indirectly. Editing audio files include a lot of details, such as shortening or lengthening the audio, adjusting the volume, adding effects, etc. 

In our previous post, we've introduced how to edit audio files in detail, so in this guide, we will mainly focus on cropping, one of the most often used skills while editing audio files. 

Tips: If you haven't gotten your audio files prepared, you can record your voice on a computer first, and then follow this guide to crop your audio files. 

Method 1. How to Crop MP3 with an MP3 Cropper

The first method we'd like to recommend is to use this free and user-friendly MP3 cropper - EaseUS MakeMyAudio. It is a 9-in-1 tool that can meet almost all editing needs, one of which is to crop MP3 files. While cropping an audio file, you can adjust the speed and volume of your MP3 files, add Fade In/Out to smooth the audio transitions, or add effects to change the voice of your audio files. Anyway, it has almost all the capabilities you could expect from an MP3 cropper. 

Besides being an MP3 cropper, it also has the ability to do many other editing jobs, such as:

• Cut audio clips and join multiple audio files
• Convert audio files between different formats
• Extract audio from video files
• Edit ID3 tags
• Create ringtones for iPhone
• Extract audio from CD
• Create audio CDs from your favorite music

If you want to give it a try, you can download it on your computer and then follow this simple tutorial to crop MP3 files. 

Step 1. Open EaseUS MakeMyAudio on your computer and click "Cutter" to move on.

Step 2. Click "Add Files" to upload the audio files you want to edit. 

Step 3. Once you've imported files, you can set the output format and output folder. Then, click "Cut" from the top menu to open the editing page. 

Step 4. On the editing page, you can set the start and end time of the track, adjust its speed, change the voice, or adjust the volume. After making changes, click "OK" to finish the process.

Method 2. How to Crop MP3 Online

Another convenient option to crop MP3 is to use some online audio cutters, which are websites that offer some editing services. By using such tools, you don't have to install any programs. That may sound convenient, but they also have shortcomings, and the most obvious one is their limited features. To keep the browser running smoothly, the web developer won't add many tools to its site. 

So, you can give up this option if you want to make some complex trim. While if just want to crop an MP3 at once, you can use either of the following online audio cutters to crop your MP3 songs. 

1. TwistedWave Audio Editor
