Once you insert an audio clip into your presentation, you may find that it is too long, or there may be parts in the clip that you don't want the audiences to hear. Or maybe you just need a small bit to play -- like the sound of that trumpet blowing! Although you can scrub the clip using the Player Controls bar (highlighted in red within Figure 1, below) to ascertain where you want the clip to begin and end, that option may become monotonous and inaccurate -- and it also looks very unprofessional if you try scrubbing an audio clip right in front of your audience. Fortunately, PowerPoint's Trim Audio option can make this easy for you -- follow these steps to explore how you can trim an audio clip right inside PowerPoint 2013:
- Open your presentation, and navigate to the required slide where you have already
inserted an audio clip. Just select
or double-click the audio clip to bring up the two contextual Audio Tools tabs in the
Ribbon. These two tabs are
Format and Playback -- click the Playback tab to activate
it, as shown in Figure 1 (highlighted in blue).

- Now, within the Audio Tools Playback tab, click the Trim Audio button,
as shown highlighted in red within Figure 2.

- This opens the Trim Audio dialog box, as shown in Figure 3. Notice that
any Bookmarks you may
have added to your audio clip also show up within the dialog box (as shown highlighted in
red within Figure 3, below). If your audio clip has no
Bookmarks, then do not worry -- you can still follow the process mentioned on this page. Additionally, you
will see a sound wave representing your audio track.

Also, do notice green and red markers representing the Start and End positions, highlighted in blue within Figure 3, above. In addition, the positions of these markers at any given time are shown in the Start Time and End Time boxes (highlighted in green within Figure 3, above).
- If you have added
to set your Start and End times, follow further – if not, skip to
Now drag the green and red markers to overlap the bookmarks, as shown in Figure 4, below. Notice that the markers will not snap to your Bookmarks, so try to be as precise as you can.

- If you have no bookmarks added, you will have to first play the audio to ascertain where you want to start
and end the audio clip. Play the audio by clicking the large Play button, highlighted in
red within Figure 5. When you reach the position where you want
to start playing the trimmed audio clip, click the Pause button. Now, go ahead and set this
paused position as the Start position using any of these approaches:
- Place your cursor over the green marker to see the two-headed arrow (highlighted in
blue within Figure 5). Then click and drag the green marker to
the same position where you paused.
- Make a note of the time position, and manually enter the time value within the Start Time
box (highlighted in green within Figure 5).

- Place your cursor over the green marker to see the two-headed arrow (highlighted in blue within Figure 5). Then click and drag the green marker to the same position where you paused.
- After setting the Start position, play the audio again. When the position where you want
to end playing the audio clip is reached, pause the audio. Now, set your End position as well
by either dragging the red marker to the paused position, or by manually entering the time value within the
End Time box.
- Before you trim the clip, preview which parts are included by clicking the Play button
again (highlighted in red within Figure 5, above) -- make
changes if you are not satisfied.
- Once you are happy with the part included in the trimmed audio clip, go ahead and trim by clicking the
OK button, highlighted in red within Figure 6,

- This will take you back to the slide with the trimmed audio clip. Note that although the audio is trimmed,
you have not lost the parts that were trimmed off -- to get them back, or to change the Start
and End points again, just select the audio clip and click the Trim Audio
button again. This will get you to the same Trim Audio dialog that you saw last in
Figure 6, above -- you can actually drag the green and red markers again to their original
positions, and all the trimming will be undone!
Note: You can only edit the start and end points of audio as long as you do not use any of the Compress Media options -- once you compress the audio clips, the trimming will be final, and not editable henceforth.
- Make sure you save your presentation.
