How to make and add a custom sound on TikTok

How your own original TikTok sounds can make you go viral

To make your custom sound go viral on TikTok, you need to upload a video with original audio. Once you post it, other users can click on your audio, listen to it, and decide if they want to use it in their own videos. The more people who use your sound, the more likely it is to spread and get noticed, which can help you go viral.

The audio in your video is visible to others, and they can see how many people have already used it, watch those videos, and save the sound so they can use it in their own content.

If your new sound is funny, relatable, or catchy (like a catchy song remix, a mashup, or a memorable quote from a movie or show) it could quickly become part of a trend. As more creators use your sound, it can gain momentum and reach a larger audience, making you go viral as the creator of the sound.

How to upload a custom sound to TikTok:

1. Open the TikTok app and tap the “+” button at the bottom to start a new video.
2. Record a video or upload one from your camera roll that you want to use as your sound.
3. Tap “Sounds” at the bottom of the screen, go to “My Sounds,” and tap “Add Sound.”
4. Choose your audio by uploading a video or screen recording from your device or recording it directly in the app.
5. Give your sound a name, add a description, and decide if you want to make it public or keep it private.
6. Hit “Save” to add your sound to your “My Sounds” library.
7. When you’re ready to use your sound, select it from your library, and don’t forget to add hashtags and descriptions to help others find it!

QUICK TIP: If you only want to save your sound without making the video public, set the Who can watch this video option to Only me. On this same page, you can also edit the sound name, add a caption, include hashtags and mentions, and adjust the visibility settings as needed.

How to record a video with an original sound on TikTok:

1. Open the TikTok app and tap the “+” button to start a new video.
2. In a place without background noise, hold down the record button while speaking, singing, or making the sound you want to use.
3. Finish the recording, apply any sound effects you like, and TikTok will automatically save the audio with the video.

Here’s how to record an original sound on Capcut:

1. Open CapCut, tap “New Project,” and pick the video you want to edit.
2. If you want to mute the original audio, tap the Mute button (this step is optional).
3. Tap “Audio” at the bottom, then select “Voiceover.”
4. Press and hold the record button to add your sound, then release it when you’re done. Tap the checkmark to save it.
5. Drag the voiceover to the right spot on the timeline or adjust the volume if needed. If you want to add more recordings, just repeat the steps. 
6. When you’re done, tap ‘Export’ in the top-right corner. Choose ‘Export without watermark’ to share it straight to TikTok, or just tap ‘Export’ to save it to your device first and share it later.

How to edit your TikTok sound

Editing your sound keeps it clear, engaging, and ready to use in your videos. You can make edits directly on TikTok or with external tools.

Here’s how to edit a TikTok sound using TikTok’s Editing Tools:

1. After recording your video, go to the “Adjust Clips” option to refine your sound timing.
2. Use the volume feature to balance your original sound with any background music.
3. Add effects like echo or reverb to enhance your audio if needed.

Here’s how to edit a TikTok sound using external editing apps:

1. Import your sound into an audio editing app like CapCut or any other online editor.
2. Trim unnecessary parts, adjust the volume, or apply effects.
3. Save the final version of your audio file.

How to do a voiceover on TikTok:

1. Open TikTok, tap the “+” button, and either record a new video or upload one from your device. Once you’re done, tap the checkmark to go to the editing screen.
2. On the right side of the editing screen, tap the down arrow and select the “Voice” button (it looks like a microphone).
3. Move the white line to go through the frames in the video and spot where you want your voiceover to start. Press and hold the ‘Record’ button while speaking into your microphone. If you make a mistake, you can re-record any part of the video until it sounds right.
4. If you decide you don’t want the original sound from your video, uncheck the “Original sound” option at the bottom left of your screen. Then, tap “Done” at the bottom left to preview your voiceover with the video.
5. Once you’re happy with your voiceover, tap “Save” to return to the editing screen. From there, you can add text, effects, or other final touches. When everything is ready, tap “Next” to write your caption and upload your video.

Examples of sounds that go viral on TikTok:

1. Music mashups
2. Lines from popular TV shows
3. Relatable evergreen lines

1. Music mashups

EXAMPLE: The Chappell Roan and Phantom of the Opera mashup

The best TikTok sound mashups:

A. Pair sounds that make SO much sense together

B. Pair sounds that make (seemingly) NO sense together

For this one, we went with the second option, with this creative mashup of Chappell Roan’s “Pink Pony Club” with The Phantom of the Opera. But this is exactly why this dramatic pairing has gone viral, giving users an interesting (and humorous) way to add a theatrical twist to real-life scenarios. Think of it like an expectations vs. reality type of situation:

The dramatic rise in The Phantom of the Opera section matches the end reveal, creating a hilarious and over-the-top effect.

But that’s not the only way people use this sound. Here are some other creative takes users tried with it:

• “Me the second the weather gets slightly chilly,” embracing a heavier, autumnal aesthetic that matches the dramatic element of the mashup.
• ‘Me loving that my daughter has my same type of humor…Her telling the TSA agent she doesn’t know who I am,” showing the struggles of parenting.
• “Coming to your room after the event and forgetting how you left it.” Well, we all know what this one feels like.

This is one of those popular sounds that is also perfect for spooky season, with plenty of creators using it as a transition for a dramatic Halloween costume change. 

2. Lines from popular TV shows

EXAMPLE: Look at this OMG*

When did reality TV become so *well* real? For context, this snippet comes from Keeping Up with the Kardashians and it goes like: 

Kris: Look at this!

Friend: Perfect! Oh my God! 

Kris: Isn’t it great?

Friend: Kris!
Kris: I know, it’s my dream!

Friend: I have goosebumps everywhere. This is out of this world!

And then it goes on about something birthday-related, but we didn’t go that far. However, this is why this sound makes complete sense. If you have a product, a service, or something you made that you’re really proud of, you can easily showcase it via this sound. For reference, check out this example:

This way, you can save yourself the awkwardness of becoming overly promotional. Just add context to your video as a text overlay so your audience understands what you’re promoting. 

3. Relatable evergreen lines

EXAMPLE: I am obsessed with this

What’s that one thing that you really like, maybe a little too much?  We’re not here to judge, as long as it doesn’t hurt anyone. But we have a TikTok sound that can work for you, and it goes like this: “People think I’m obsessed with this, but I’m OK with it, I am obsessed with this. And I think this is an obsession that doesn’t hurt anyone.”
