and if it's on TikTok, just download a video that uses the audio, open a new project in capcut or inshot. and import the videos you want to use. now import the video that you downloaded, right click and extract the audio. now using the sound wave on the timeline, you can easily match up your clips to the beat.

When you upload your own music to TikTok, use music that is paid for (royalty-free, Creative Commons, or licensed through a performing rights organization), or stitch together your video on top of another creator's video, these are all considered legal uses of sound on TikTok, and you will not be penalized.

The easiest way to create new audio to be used on TikTok is to simply record a TikTok. Any sound picked up in the recording of your TikTok — such as your voice or the use of an instrument — will automatically be made into a new sound when your TikTok is published.
