You can trim, delete, or re-record parts of a voice memo directly in the Voice Memos app
The Voice Memos app on iPhone lets you edit recordings without leaving the app or using a computer. You can shorten a memo by cutting the beginning or end, delete a section from the middle, or re-record over a portion you want to change. The edits happen to the file itself — you are not creating a separate version.
The editing tools are basic but functional. You cannot add music, layer multiple recordings, or adjust volume in the middle of a memo. If you need those features, you would move to a more advanced app like GarageBand or Adobe Audition. For trimming, removing silence, or fixing a flubbed sentence, the built-in editor is enough.
Key Takeaways
- Open the memo you want to edit, tap Edit, and use the trim handles at the start and end to cut unwanted sections.
- To delete a section from the middle of a recording, tap Delete and drag across the portion you want to remove.
- You can re-record over a specific part by tapping Resume and choosing to record from a particular point in the memo.
- All edits save automatically to the original file — there is no separate "save" step or undo button after you close the memo.
- If you make a mistake you cannot undo, you can recover the memo from Recently Deleted for 30 days.
How to trim the start or end of a voice memo
Open the Voice Memos app and find the memo you want to edit. Tap it once to play it, then tap the three-dot menu icon in the upper right corner. Select Edit from the menu that appears.
You will see a waveform — a visual representation of the sound in your memo — with two vertical lines at the start and end. These are the trim handles. Tap and drag the left handle to the right to remove silence or words from the beginning. Drag the right handle to the left to cut the end. As you drag, the app shows you how many seconds you are removing. When the handles are where you want them, tap Save.
The trimmed sections are deleted permanently. If you change your mind when ready, you can tap Undo in the edit screen before you close the memo. Once you leave the app, the change is final.
How to delete a section from the middle of a recording
Open the memo and tap the three-dot menu, then Edit. Instead of using the trim handles, tap the Delete button (it looks like a minus sign in a circle, usually in the lower toolbar). The waveform will change to show a selection box in the middle.
Drag the edges of this box to select the exact portion you want to remove — for example, a cough, a long pause, or a sentence you want to redo. The app shows you the start and end time of the selection as you adjust it. When the selection covers only what you want gone, tap Delete again to remove it. The sections before and after the deleted part will join together.
This is useful when you have a good recording overall but need to cut out one mistake or interruption without re-recording the whole thing.
How to re-record part of a voice memo
If you want to fix a specific section rather than delete it, you can re-record over it. Open the memo and tap the three-dot menu, then Edit. Tap Resume (or the play button, depending on your iOS version).
The memo will start playing from the beginning. Listen until you reach the point where you want to start recording over. Tap the Record button (the red circle) to begin recording new audio at that exact moment. The app will record over everything from that point forward, replacing the old audio with your new words.
This is faster than deleting and re-recording separately, because you do not have to line up the timing yourself. The new recording picks up exactly where you stopped the playback.
Understanding the waveform and selection tools
The waveform is a visual map of your recording. Tall peaks represent loud sounds, and flat sections represent silence or very quiet audio. When you are trimming or deleting, you can see exactly where the sound is, which helps you cut at the right spot.
The selection box (when you tap Delete) snaps to the nearest sound boundary by default, so you do not have to be pixel-perfect with your dragging. If the snap is too aggressive and you need finer control, drag more slowly or tap directly on the waveform to set a precise point.
The time display at the bottom of the edit screen shows you the exact start and end time of your selection or trim. If you are removing a specific 5-second section, you can watch the numbers and stop dragging when you hit the right duration.
What happens to your edited memo
When you save an edit, the change applies to the original file. You do not get a choice to save as a new file or keep both versions. If you want to preserve the original, you should duplicate the memo before editing it. To duplicate, tap the three-dot menu on the memo in the list view and select Duplicate.
Edited memos stay in the Voice Memos app in the same folder where you originally saved them. If you delete a memo by mistake, you have 30 days to recover it from the Recently Deleted folder. After 30 days, it is gone permanently.
When to use Voice Memos editing versus other apps
The Voice Memos editor is built for quick fixes: trimming silence, removing a cough, cutting out a wrong sentence. It is fast and does not require learning new software.
If you need to combine multiple recordings, adjust volume levels, add background music, or make more complex edits, move your memo to GarageBand (free on iPhone) or a paid app like Adobe Audition. You can export your memo from Voice Memos and import it into these apps. GarageBand is a good middle ground — more powerful than Voice Memos but still straightforward for basic audio work.
For transcription or converting speech to text, Voice Memos has a built-in transcription feature (on iOS 17 and later) that you can access by tapping the memo and looking for the transcript option. This does not edit the audio itself, but it creates a text version you can read or search.
Frequently Asked Questions
Can I undo an edit after I close the memo?
No. Once you save an edit and close the memo, you cannot undo it within the app. If you made a major mistake, you can recover the memo from Recently Deleted within 30 days, but you will get the deleted version, not a version with the edit undone. Always listen to your edited memo before closing the app if you are unsure about the change.
What if I accidentally delete a memo?
Open Voice Memos, scroll to the bottom, and tap Recently Deleted. You will see memos deleted in the last 30 days. Tap Edit, select the memo you want, and tap Recover. After 30 days, memos in Recently Deleted are erased permanently.
Can I edit a memo on my Mac if I started on iPhone?
Voice Memos syncs across devices if you use iCloud. A memo you edit on iPhone will show the edited version on your Mac. However, the Mac version of Voice Memos has fewer editing tools than iPhone — you can trim but not delete sections from the middle or re-record. For complex edits, do them on iPhone first.
Does editing a voice memo change the file size?
Yes. Trimming or deleting sections removes that audio data, so the file becomes smaller. Re-recording adds new audio, so the file may stay the same size or grow, depending on how much you recorded over. The file size updates automatically after you save.
Can I edit a memo I recorded in a different app?
No. The Voice Memos editor only works on files created in Voice Memos. If you recorded in another app, you would need to edit it in that app or import it into a universal editor like GarageBand.
