How to Trim an Audio Clip with Free Software (WavePad or Audacity)

This emindsca teaches you how to trim an audio clip on a Windows or Mac computer, as well as an Android or iPhone. Audacity provides a free solution for Windows and Mac computers, while WavePad provides a similar experience on your phone or tablet.

Method 1 Using WavePad Audio Editor on Phone or Tablet

1. Download “WavePad Audio Editor” from the Google Play Store or App Store. The app, offered by NCH Software, is highly rated and recommended by users.

2. Launch WavePad. This app’s icon resembles soundwaves. This can be found on one of your Home screens, in your app drawer, or by searching.

If you still have the Google Play or App Store open, choose Open or Launch.

3. Open and select Import from Music Library or Open File. If the audio file is not in your music library, use Open File to navigate to another location on your phone.

Select the file to be edited and press the Enter key.

Before you can proceed, you may need to grant the app a few permissions.

4. Tap Edit. It’s in the editing ribbon above the music wavelength.

5. Make a selection by tapping Trim. If you want the app to automatically trim the silent areas of the audio clip at the beginning or end, select Auto Trim.

Select Trim Silences to instruct WavePad to remove all silences in your audio file based on a threshold you specify.

To trim off the end or beginning of an audio clip, use your finger to mark the first part of the audio clip you want to hear or the last bit of audio in the track, then tap Trim Start or Trim End. Your selection will be used to trim the audio clip.

6. Make a backup of the edited file. Tap File in the upper left corner of your screen, then Save as. Before you save the file, you will be able to change the name and file format. To proceed, press the OK button.

Method 2 Using Audacity on Windows and Mac

1. Audacity can be downloaded from https://www.audacityteam.org/download/. Audacity is free software that can be downloaded and installed on any computer.

If you’re using a Windows computer, for example, click the button on the left side of the page to go to the download page for the most recent version of Audacity for Windows.

As instructed in the text, click the link in the text to begin the download.

To install the downloaded file, run the installed file and then either follow the Wizard or drag-and-drop an icon to your Applications folder.

2. Launch Audacity. This application and programme icon resembles a pair of over-the-ear headphones with sound waves separating the two earpieces. This can be found in your Finder’s Start Menu or Applications folder.

3. Navigate to the File menu. This is visible in the navigation menu above the editing workspace in Audacity, as well as along the top of your screen.

4. Hover your cursor over Import. The menu will expand to include import options.

5. Select Audio. The file browser will launch.

You can also import an audio file by dragging it into the Audacity window. If you do, proceed to the next step.

6. Double-click your audio file to select it. The file will open and you’ll see its waveform.

7. Select the audio you want to keep with your cursor. Click the first section of audio you want to keep, then hold down the Shift key on your keyboard and click the opposite end of the audio you want to keep. The other audio will not be highlighted and will be deleted eventually.

If you need a closer look at the wavelength, use the zoom tools.

8. Click Edit. It’s at the top of the editing space.

9. Click Remove Special and Trim. All the audio that you don’t have selected will be deleted.

If you made a mistake, you can always click the “Undo” or “Redo” buttons in the Edit menu.

10. Save your project. You can go to File > Save to save the Audacity project, but if you want to use the file in other programs, you’ll need to export it.

To export your file, just go to File > Export > Export Audio and select the file format to save it in.
