Quick Answer:
Nowadays, recording life with pictures and videos has become easier than ever before due to the advanced lenses on smartphones, like the iPhone. Moreover, the built-in apps on iPhone and Mac make it easy to edit your multimedia files. The problem is that some users still do not understand how to use the advanced features in the preinstalled apps. Therefore, this guide explains how to do a voiceover with iMovie on iPhones and Mac computers.
For a detailed guide on adding voiceovers on Mac, we have added two guides below, which will cover the step-by-step solution on adding voiceovers on Mac with detailed instructions. We also added an option for users who want to adjust the voice input setting on Mac for a more controlled audio capture.
1. Fire up the built-in video editor on your Mac, go to the Projects panel, and click the Create New button to make a new project. Next, select "Movie" from the dropdown menu.
2. Click the Import Media button and open the video that you want to edit in iMovie. Then drag and drop the video onto the timeline.
3. Next, place the playhead at the beginning point where you want to add the voiceover. Now, either click the Microphone icon at the bottom of the composition panel or choose Record Voiceover from the Window menu.
4. In the pop-up dialog, pull down the Input Source option and select your microphone, and adjust the volume. Click the red Record button and start doing a voiceover on iMovie after the countdown.
5. When the voiceover recording is done, click the Stop button under the composition panel. Your voice will be added to the timeline as a new track. Click Done at the bottom right side of the composition panel.
1. Open System Preferences.
2. In the System Preferences menu, select Sound.
3. Inside the Sound menu, go to Input. Then, choose the input device you want to use for the voiceover. Then, you can adjust the Input Volume by editing the labeled slider.
1. When you want to add a voiceover to iMovie on iPhone, start the preinstalled video editor app, and create a new movie project or open an existing project.
2. Tap the "+" icon, choose Video, and add the video from Camera Roll to iMovie. Preview the video on the timeline and find the beginning position of the voiceover.
3. Tap the "+" icon at the upper left side of the timeline, and choose Voiceover on the context menu. Now, you will be presented with the Ready to Record box.
4. Test your voice and adjust the volume. Once you are ready, tap the Record button to trigger the 3-second countdown.
5. Then record the voiceover, and tap Stop when you are done recording. Pre-listen to the voice recording, tap Accept, and press Done.
With the rise of AI, you don't always have to record your own voice. You can use AI voice generators (like ElevenLabs, Murf AI, or LOVO) to create realistic, studio-quality voiceovers and import them directly into your iMovie project.
1. Generate your voiceover script in your preferred AI voice generator and export the final audio file (preferably in WAV or MP3 format).
2. Open your iMovie project on your Mac.
3. Simply drag and drop the downloaded audio file from your Finder directly into the audio track of your iMovie timeline, positioning it right below your video clip.
Recording a voiceover is only half the battle; making it sound professional is the key. Follow these best practices:
While the built-in Mac or iPhone microphone works, a dedicated USB mic drastically improves audio richness and reduces room echo.
Record in a quiet, carpeted room. Soft furnishings (like curtains or even a closet full of clothes) help absorb sound reflections.
If your recording has a subtle background hiss, select your audio clip in the timeline, click the Noise Reduction and Equalizer icon above the viewer, and check Reduce background noise. Adjust the slider until the hiss disappears without distorting your voice.
The most common reason a voiceover fails to record in iMovie (especially on newer macOS versions like Sonoma or Ventura) is a lack of microphone permissions. If you hit record and the audio meter doesn't move, here is the exact fix:
1. Close iMovie.
2. Click the Apple menu and select System Settings (or System Preferences).
3. Scroll down and click on Privacy & Security.
4. Select Microphone.
5. Find iMovie in the list of applications and toggle the switch to the ON position to grant access.
Even with permissions granted, iMovie might be listening to the wrong device. Click the Voiceover Options icon and ensure your correct microphone is selected.
While iMovie is a fantastic free tool for basic voiceovers within the Apple ecosystem, it falls short if you are using a Windows PC or need to simultaneously mix internal system audio with your microphone.
For creators needing advanced audio routing, noise cancellation, or cross-platform compatibility, AnyMP4 Screen Recorder serves as a robust alternative. It allows for dedicated audio recording with granular control over background noise and microphone enhancement.

If you intend to record a voiceover automatically, click the Take Schedule menu and set it up according to your needs.
