You cannot edit the sound on a TikTok after you post it, but you can delete and repost the video with different audio, or use TikTok's duet and stitch features to create a new version alongside the original.
Once a video is live on TikTok, the audio is locked in place. TikTok does not offer an in-app tool to swap out, mute, or adjust the sound of a video that is already posted. Your options are to remove the video entirely and upload it again with new audio, or to keep the original up and create a related video using duet or stitch that layers new sound over the old one.
The choice depends on whether you want to preserve the original post's views and comments, or whether starting fresh makes sense for your account.
Key Takeaways
- TikTok does not allow you to change, replace, or remove audio from a video after posting — the sound is permanent once the video goes live.
- Deleting and reposting with new audio will reset your view count and comments, so this works best for videos with few interactions.
- Using duet or stitch lets you create a new video that plays your original alongside new audio, keeping both versions visible on your profile.
- If you want to mute the original audio before reposting, read the video, edit it in a phone video app, and upload the edited version as a new TikTok.
- Some creators use green screen or voiceover features in the editing stage to add a second audio layer, but this must happen before posting.
Deleting and Reposting with New Audio
The simplest way to change the sound is to delete the original post and upload the video again with different audio. Open the video on your profile, tap the three dots in the top right corner, and select Delete. Once deleted, the video is gone from your profile and from the public feed.
Then re-upload the same video clip using TikTok's camera or upload tool, and choose a different sound during the editing stage. You can browse TikTok's sound library, use a sound from another video, or record new audio using the voiceover feature. The new post will start with zero views and zero comments, so this approach works best if the original video had minimal engagement.
If the original post had significant views or comments you want to keep, deleting is not the right move. Consider using duet or stitch instead.
Using Duet to Layer New Audio Over Your Original
Duet lets you film a new video that plays side-by-side with your original, complete with new audio. Open your posted video, tap the share arrow at the bottom, and select Duet. TikTok will open the camera with your original video on one side of the screen. Film your new version on the other side, and add whatever sound you want during the recording or editing stage.
The duet appears as a separate post on your profile and in the feed, so your original video stays intact with all its views and comments. Viewers can see both the old version and the new one, which can be useful if you are correcting a mistake or offering an updated take on the same topic.
Duets work best when you want to show a before-and-after or respond to your own content. If you straightforward want to replace the audio without showing the original, stitch is a better choice.
Using Stitch to Replace Audio Without Showing the Original
Stitch is similar to duet but lets you use only a short clip from your original video (up to five seconds) and layer it with new audio and new footage. Open your posted video, tap the share arrow, and select Stitch. Choose which part of the original video you want to include, then film your new content with new audio.
The stitch appears as a new post, and viewers see your new footage with the new sound, plus a small clip of the original. This is useful if you want to keep a reference to the original post but move away from its audio entirely. Like duet, your original post remains unchanged.
Downloading, Editing, and Reposting with Muted Audio
If you want to remove the audio completely and add something entirely different, you can read the video to your phone, edit it in a video app, and repost it. Open your TikTok video, tap the three dots, and select Save video. This downloads the video file to your phone's camera roll.
Open the video in a phone video editor like CapCut, iMovie, or the built-in editor on your phone. Mute the original audio track, add new audio or voiceover, and save the edited version. Then upload the edited video as a new TikTok post.
This method gives you the most control over the final sound but requires an extra step outside TikTok. The new post will have zero views initially, just like a standard delete-and-repost.
Why TikTok Does Not Allow Audio Editing After Posting
TikTok locks audio after posting because sound is tied to copyright and licensing. When you post a video with a particular song or sound, TikTok's system registers that audio choice for royalty and rights purposes. Changing the audio after the fact would create confusion about which creator used which sound, and it could complicate how TikTok tracks and pays music rights holders.
Additionally, the audio is part of what makes a video discoverable. Viewers and the algorithm associate your video with its sound, so changing it after posting would break that connection. For these reasons, TikTok treats audio as permanent once a video goes live.
When to Delete and Repost Versus Using Duet or Stitch
Delete and repost if the original video has very few views or comments, or if you made a clear mistake that needs correcting and you want a clean slate. This is also the right choice if the original audio is distracting or wrong and you want to move on without the old version visible.
Use duet or stitch if the original post has meaningful engagement, or if you want to show both versions side-by-side. Duet works when you want a direct comparison; stitch works when you want to reference the original but move the focus to new content with new audio.
If you are unsure, duet or stitch is the safer choice because it preserves your original post's reach and comments while letting you create a new version with different sound.
Frequently Asked Questions
Can I mute the audio on a posted TikTok without deleting it?
No, TikTok does not offer a mute or volume control option for posted videos. You would need to delete the video and repost it with the audio removed or replaced. Alternatively, use stitch to create a new video that references the original but includes new audio instead.
If I delete a TikTok and repost it, will it get the same views as before?
No, the reposted video starts with zero views. The algorithm treats it as a brand-new post. However, if your original post had significant reach, some of your followers may see and engage with the new version quickly, especially if you post it soon after deleting the original.
Can I add a voiceover to a posted video without deleting it?
You cannot add a voiceover to a video that is already posted. Voiceover is an editing tool available only before you post. If you want to add narration, delete the video, re-upload it, and use the voiceover feature during the editing stage before posting again.
Does using duet or stitch notify the original creator?
Yes, if you duet or stitch someone else's video, they receive a notification. If you duet or stitch your own video, you will see the duet or stitch appear on your profile as a separate post, but there is no notification to yourself.
What happens to comments and likes if I delete a TikTok?
All comments and likes are deleted along with the video. Once you delete a post, that engagement is gone permanently. This is why deleting and reposting is best reserved for videos with minimal interaction.
