You can upload your own audio to TikTok in three ways: record sound directly in the app while filming, add audio after you've recorded video, or use audio you've already saved to your phone
TikTok's built-in sounds library is enormous, but sometimes you want to use your own music, voiceover, or audio clip. The method you choose depends on whether you're recording fresh video or working with something you've already filmed, and whether your audio is already on your phone or needs to be captured in the moment.
The most straightforward path is recording sound while you film — TikTok captures whatever audio is happening around you or through your phone's microphone. If you're adding sound to video you've already shot, you'll use the editing tools after you've selected your clip. If you have an audio file saved somewhere else on your phone, you can import it directly into TikTok during editing.
Key Takeaways
- When you film a TikTok video, TikTok automatically records whatever sound is in the room or coming through your microphone unless you mute it.
- To add audio after filming, open the video in the editor, tap the sound icon, and choose to upload audio from your phone's files or record a new voiceover.
- You can only upload audio files that are already saved on your phone — TikTok cannot download audio directly from the internet during the upload process.
- Audio you add becomes part of your video and cannot be separated later, so test the volume and timing before you post.
- Copyright-protected music will trigger TikTok's detection system, and the platform may mute it, add a warning, or restrict who can watch your video.
Recording sound while you film
When you open TikTok's camera and start recording, the app captures audio from your phone's microphone by default. This means any sound in your environment — your voice, music playing, background noise — becomes part of your video automatically. You don't need to do anything extra; TikTok is listening the moment you press record.
If you want to film silently and add sound later, mute the audio before you start recording. Look for the microphone icon in the top right corner of the camera screen and tap it to turn off sound capture. The icon will show a line through it when muting is active. This is useful if you're filming in a noisy place or want to add a voiceover in post-production instead.
The audio quality depends on your phone's microphone and how close you are to the sound source. If you're recording yourself speaking, position your phone close enough that your voice comes through clearly but far enough that you're not picking up wind noise or rustling. For music or other audio playing in the background, make sure the volume is loud enough to be heard clearly in the final video.
Adding audio after you've filmed your video
If you've already recorded video without sound, or you want to replace the audio you captured, you can add it during editing. After you've filmed and the preview screen appears, tap "Next" to move to the editing tools. You'll see several icons at the bottom of the screen — tap the one that looks like a musical note or sound wave.
TikTok will show you options: "Sounds" (the built-in library), "Upload Audio" (to add a file from your phone), and "Record Voiceover" (to add your voice after the fact). If you're adding your own audio file, tap "Upload Audio." Your phone's file manager will open, and you can navigate to wherever your audio file is saved — usually in a Music, Downloads, or Documents folder depending on where you downloaded or saved it.
Once you've selected your audio file, TikTok will import it and place it at the beginning of your video. You can then adjust where the audio starts and stops by dragging the timeline, and you can adjust the volume using the volume slider. If your audio is longer than your video, it will be cut off at the end of the video. If your video is longer than the audio, there will be silence after the audio ends unless you add another sound.
Recording a voiceover or adding audio in real time
If you want to add your own voice or narration after filming, use the "Record Voiceover" option in the sound editor. After you've tapped the sound icon and selected "Record Voiceover," TikTok will play your video and let you record audio while watching it. This is useful for adding commentary, explaining what's happening, or creating a spoken introduction.
Position your phone so the microphone is close to your mouth but not so close that you're creating plosive sounds (the harsh "p" and "b" sounds that can distort audio). Speak clearly and at a consistent volume. TikTok will record your voice and layer it on top of any existing audio in your video — it won't replace the original sound unless you choose to mute it first.
If you make a mistake while recording your voiceover, you can delete it and try again. The voiceover appears as a separate audio track in the editor, so you can adjust its volume independently of any background audio. This means you can record yourself speaking over music, or over the original sound from your video, and control how loud each one is.
Understanding file formats and where to find your audio
TikTok accepts audio files in common formats: MP3, WAV, M4A, and AAC are the most reliable. If you have an audio file in a different format, you may need to convert it before TikTok will recognize it. Free conversion tools like CloudConvert or Audacity can change the format without losing quality.
Your audio file needs to be saved somewhere on your phone that TikTok can access. If you downloaded a song or audio file, it's usually in your Downloads folder. If you recorded audio using your phone's voice recorder app, it's typically in a Recordings or Voice Memos folder. If you're not sure where a file is, use your phone's file manager app to search for it by name.
One important limitation: TikTok cannot download audio directly from the internet during the upload process. If you want to use audio from YouTube, Spotify, or another streaming service, you'll need to download it to your phone first using a separate tool, then import it into TikTok. Be aware that downloading copyrighted music without permission violates the terms of most streaming services and may violate copyright law depending on where you live.
What happens when TikTok detects copyrighted music
If your audio contains copyrighted music, TikTok's detection system will identify it. The platform uses fingerprinting technology that recognizes songs even if they're partially obscured by other sounds. When TikTok detects copyrighted audio, several things can happen depending on the copyright holder's settings.
The copyright holder might allow the music to stay in your video but claim the revenue from any views — meaning you won't earn money from that video even if you're part of TikTok's Creator Fund. They might add a warning label that tells viewers the video contains copyrighted material. In some cases, they might mute the audio entirely, leaving your video silent. Or they might restrict who can watch your video — for example, only allowing it to be seen in certain countries where the copyright holder has licensed the music.
If you're uploading audio you created yourself — a song you wrote and recorded, a voiceover you made, or audio from a royalty-free library — TikTok won't flag it. But if you're using someone else's copyrighted music, expect TikTok to detect it and apply whatever restrictions the copyright holder has set up.
Troubleshooting audio that won't upload or play
If TikTok won't let you upload an audio file, the most common reason is that the file format isn't supported. Check that your file is MP3, WAV, M4A, or AAC. If it's in a different format, convert it first using a free tool.
If the audio uploads but doesn't play, or plays very quietly, the file itself might be corrupted or the volume might be set too low. Try adjusting the volume slider in the editor to maximum. If it's still silent, try uploading a different audio file to see if the problem is specific to that file or a broader issue with your phone or TikTok app.
If your phone's file manager can't find the audio file, make sure it's actually saved on your phone and not just in a cloud storage service like Google Drive or iCloud. Files stored only in the cloud won't appear in TikTok's file picker. Download the file to your phone's local storage first, then try uploading it again.
Frequently Asked Questions
Can I use music from Spotify or YouTube in my TikTok?
Not directly — you'd need to download the audio file to your phone first using a separate tool, then import it into TikTok. However, downloading copyrighted music without permission violates the terms of those services and may violate copyright law. TikTok's built-in sounds library is a safer option for music you want to use.
What if I want to remove the original audio from my video and replace it with something else?
In the editor, tap the sound icon and select your new audio. Before you do, you can mute the original audio by adjusting its volume to zero. This leaves your video silent except for the new audio you're adding. The original audio won't be deleted from the video file itself, but it won't be heard.
Can I use the same audio file in multiple TikTok videos?
Yes. Once you've uploaded an audio file to one video, you can use it in other videos by uploading it again. Each video is independent, so using the same audio in multiple videos won't cause any problems.
Why is my audio out of sync with my video?
This usually happens when you record audio separately from video and they don't line up. In the editor, you can adjust where the audio starts by dragging the timeline. If the audio is consistently off by the same amount, you may need to trim the beginning of the audio or the video to get them to match.
Will TikTok let me monetize a video if I use my own audio?
Yes, as long as the audio is yours or you have permission to use it. If TikTok detects copyrighted music, the copyright holder may claim the revenue instead. Audio you created yourself, or audio from royalty-free libraries, won't trigger copyright claims.
