Your audio content will now be loaded into Audacity. For this example, I have used a music recording but the content can be any audio. Audacity supports all the main file types including WAV, MP3, and AIFF.

How To Trim Audio In Audacity

Whether it be the recording of a song, podcasts, interviews, or any other type of content, you will have to trim your audio to make sure there is no dead space at the beginning or end of the audio. With the recording of a song, this might be a count-in that is no longer needed.

With a podcast, it may be a delay before the speaking begins.

Either way, trimming down unnecessary parts will make sure your content is delivered more concisely. There are two ways to trim audio. First, we will look at trimming the beginning or end of your audio.

How To Individually Trim Beginning or End

  1. Firstly click on the Selection Tool or alternatively press F1. The Selection Tool has been circled on the graphic below and looks like the ‘I’ found in word processing
    selection tool
  2. Before you cut you may want to zoom in for improved accuracy. This action can be done by pressing Ctrl + 1 on the keyboard or clicking View, Zoom then Zoom In from the top menu. Also, the Zoom button can focus on a part of your audio.For this example, I will cut the end of the audio. As you can see there is plenty of dead space that needs to be deleted. Simply highlight the unwanted audio with the Selection Tool by clicking the left cursor on your mouse, and drag to the required length.

  3. Next, click on Edit, Remove Special and Split Delete or press Ctrl + Alt + K. The highlighted audio will now be removed.

How To Trim Both Beginning and End Simultaneously

  1. If you want to trim audio at both beginning and end at the same time, this can be done by the use of the Trim Audio feature. For this, you want to use the Selection Tool to highlight the audio that you want to keep. To ensure that you like this selection you can listen to the selection by pressing the SpaceBar or click the play button.

  4. With the Time Shift Tool engaged, use the left mouse to drag your recording to your required time. A yellow line will appear when snapped to the very beginning.

  5. For an even further professional finish, you may want to try the Fade In or Fade Out feature. Highlight the area you want to Fade In or Out using the Selection Tool. Then go to Effect and click Fade In or Fade Out. If you are tidying the beginning of your audio go to Fade In and if you are fading out the end, use Fade Out.

How To Cut In Audacity

Cutting audio is important if you have an error in the middle of your production.

This can be an unwanted section, or you may want to delete errors or mechanical noise. For this example, I will be using a vocal recording. Load your audio file as outlined in the ‘How to Use Audacity’ section. To cut audio in Audacity follow these two steps.

  1. Using the Selection Tool button, left click on your mouse and drag over the error or area that you want to cut. You will see the selected area highlighted darker. To adjust, use the Finger Tool to drag in or out. Playback the area to make sure it is the correct part you want to delete.

  2. Press the delete key on your keyboard. Or click Edit then Delete on the top menu.

How To Split Tracks In Audacity

You may want to try the Audacity split track option to cut your audio.

This is a good option if you want to add a gap in your audio. This can be used to add space for an interlude such as a jingle or an advert. Once your audio is split into two parts it can be dragged apart to leave a space or simply deleted.

Using The Selection Tool, Select Where You Would Like To Split The Audio

  1. Open the Edit menu then click Clip Boundaries followed by Split. A dark line will appear where the audio file has been split into two.
    click Clip Boundaries
  2. Press the Time Shift Tool to drag a gap into the audio.
