The audio trim is a primitive tool available under the Audio or Add Audio feature on TikTok that allows you to set a different starting point for your video. Before you learn how to use it, it’s important to understand that you can’t trim audio to create a custom mix using the Audio trim feature on TikTok.

Likewise, the sound trim function can only be used if the duration of the sound is longer than the preset time for filming the video. For example, if you have the camera mode set to 30 seconds, but your track is also 30 seconds or shorter, you will not be able to 'trim' the track to start at a different point.

Now that we have that out of the way, let's learn the ins and outs of trimming audio in the TikTok app.

You can add audio to a TikTok before or after you record it. Adding audio before you record gives you the added benefit of filming in better sync with the music or voiceover than if you were to edit the filmed video to match the music later. Let’s take a look at how to add and trim audio on TikTok before you record.
