iMovie is a user-friendly editing program that allows users to crop sound in a few simple steps. iMovie is available on both Mac and iOS devices and offers a range of features for editing audio clips, including trimming, adjusting volume, and changing speed. Users can also detach audio from video clips, allowing for separate editing of the audio component. While iMovie does not support splitting audio clips, there are workarounds, such as editing the audio outside of iMovie and then reassembling the shorter clips within the program. With its intuitive interface and audio editing capabilities, iMovie empowers users to enhance their projects by cropping and refining sound to their desired specifications.

What You'll Learn
Splitting an audio clip
To split an audio clip in iMovie, you must first ensure that there is a visual element or layer "above" the audio clip. This could be an iMovie background or any other type of video clip. This is because iMovie relies on connections between clips, and without a visual layer, the new bit of the audio clip would have nothing to attach to.
Once you have added a visual layer, you can split the audio clip. On a Mac, select the clip in the timeline that you want to split and position the playhead where you want to split the clip. Then, choose Modify > Split Clip. On an iPhone, tap the clip (it will become outlined in yellow), then swipe down over the playhead to split the clip as if you were using your finger to slice through it.
You can also split audio tracks the same way you can split video tracks. To do this, you need to select the point of each split in a project by left-clicking in the timeline, then right-clicking to access the options, which include the split clip. If you do this twice, you will have isolated one section of the audio or video.
Another method for splitting an audio clip is to place your cursor on the audio clip at the beginning of the part that you want to delete. While holding down the 'r' key, drag the cursor along the clip. A yellow box will appear, outlining the range that you want to delete. Press delete on your keyboard to delete the range.
If the split clip option is not working, you can try deleting your preferences. To do this, open iMovie while holding down the Option and Command keys and select to delete preferences in the box that appears. iMovie will then open in a new library. To get back to your projects, reopen your old library. Now see if the Modify/Split Clip procedure works.

Trimming an audio clip
To get started, open your iMovie project and locate the audio clip you want to trim on the timeline. You can then use the playhead (the white vertical line) to identify the exact point where you want to make your cut.
The next step is to use the Trim tool. Simply click on the audio clip to select it, and then click the scissors icon on the clip to activate the Trim mode. Two yellow trim handles will appear at the beginning and end of the selected clip, indicating where you can make your adjustments.
Now, you can start refining the duration of your audio clip. Drag the yellow handles to the desired position to shorten or lengthen the clip. As you do this, you'll see a preview of the waveform, which helps you visualize the audio and make more precise cuts.
Fine-tuning your trim points is easy. If you need to adjust the start or end point in small increments, simply use the left and right arrow keys on your keyboard. This allows for frame-by-frame adjustments, ensuring you get the perfect trim.
Once you're happy with your trimming, click the "Done" button to exit Trim mode. Your audio clip will now be cropped to the exact length you specified.
With these simple steps, you can easily trim audio clips in iMovie, giving you greater control over the timing and duration of your sound.

Adjusting the volume
To adjust the volume of the entire clip, select the clip and then tap the Volume button. You will see a slider that you can move to turn the volume up or down. The percentage of volume change will be visible as you move the slider.
To adjust the volume of only a specific portion of the clip, you can use keyframes. Keyframes are markers that you can add at specific points in a clip to change the volume at those points. In the iMovie app on your Mac, open the clip in the timeline and move the pointer to the volume control (the horizontal line) at the point where you want to add a keyframe. To add a keyframe, hold down the Option key and click the volume control. You will see the pointer change to the Add Keyframe pointer when you can click to add the keyframe. You can add as many keyframes as you want, but you must add at least two to adjust the audio over time, as volume adjustments are made between two keyframes.
Additional Tips
- When adjusting the volume, ensure that the peak sections of the waveform do not turn yellow or red, which indicate distortion and severe distortion (clipping), respectively. If you see red or yellow in the waveform, lower the volume until the entire waveform is green.
- You can also modify the transition into and out of the modified portion by moving the yellow dots on the volume bar. Move the pointer over a dot until it turns into a hand, then drag to lengthen or shorten the transition.
- To play back changes to the selected clip, move the playhead (the red vertical line) to the left of the clip and press the Space bar. Press the Space bar again to stop the playback.
- You can also create a fade-in or fade-out effect by selecting a clip in the Timeline and dragging the fade handle (small circle) at the beginning or end of the clip.

Changing the speed
IMovie is a built-in video editor for Mac, iPad, and iPhone users. It offers a range of editing features, including the ability to change the speed of audio clips.
To change the speed of a clip in iMovie, first, select the clip in the timeline whose speed you want to change. Then, click the Speed button to show the speed controls. From the Speed pop-up menu, choose either Slow or Fast, and click a speed button to set the speed. An icon, either a turtle or a rabbit, will appear on the clip, and a speed slider will appear at the top. Drag the slider to the right to slow down the clip or to the left to speed it up.
If you want to preserve the original pitch of the audio while changing its speed, select the Preserve Pitch checkbox above the viewer. By default, iMovie preserves the pitch of audio clips that are sped up or slowed down. However, if you want to change this, tap the Project Settings button and turn on "Speed changes pitch."
Additionally, you can adjust the speed of specific ranges within a clip. To do this, select a range in the clip by holding down the R key and dragging across the clip. Then, drag the speed slider at the top of the clip to adjust the speed of the selected range.
It's worth noting that iMovie lacks the flexibility to fine-tune the edited soundtrack for built-in media stock. If you're looking for more flexibility in audio editing, you might consider alternatives such as FlexClip, which allows you to change the audio speed up to 8 times and save the edited soundtrack in MP3 format.

Detaching audio from a video clip
To detach audio from a video clip in iMovie, open a movie project and tap on the video clip in the timeline to reveal the inspector at the bottom of the screen. Tap the Actions button and then tap Detach. A new blue-coloured audio clip will appear below the video clip. Now, you can move, delete, or edit the audio clip separately from the video.
You can also move an entire audio clip to a different place in your project. To do this, touch and hold a blue or purple audio clip in the timeline until it pops off the timeline. Then, drag the clip to a new location in the timeline and release.
Additionally, you can trim an audio clip by dragging its ends to the left or right to increase or decrease its length. If you want to split an audio clip, scroll the timeline to position the playhead where you want to split it. Then, tap the clip to reveal the inspector and tap Split. Alternatively, you can tap the clip, swipe down over the playhead to split it, or place your cursor on the audio clip at the beginning of the part you want to delete, and while holding down the R key, drag the cursor along the clip. A yellow box will appear to outline the range to be deleted.
Once you've detached the audio, you can make further adjustments such as changing the volume, speed, pitch, and adding audio effects.
