A trimmed audio is a song or tune that has been cut to make it shorter. Audio’s are edited in such a way when content creators need a specific sound to match their video upload, and to prevent the audio from not making any sense. The trimmed TikTok audio is a section from a whole tune.

TikTok users need to trim their audio’s in order to match the length of their videos.

How long can a TikTok video be?

A TikTok video can be 15 or 60 seconds long, as well as up to three minutes depending if you are creating, or uploading a video.

Due to the shortness of TikTok videos, it is inevitable that you will need to trim your desired audio’s when posting your content, but why won’t TikTok let you trim your sound?

Why won’t TikTok let me trim my audio?

TikTok won’t let you trim your audio if you are trying to cut the sound to a section that is not available for use. This is not always the case on every audio, however, there are certain songs that do not begin at the very start, so you are unable to complete a unique cut of the audio.

Another reason why TikTok won’t let you trim your audio if you are trying to cut an original audio from the TikTok platform. If you need to use the specific sound, you will need to export the audio into a third party app that will allow you to complete the necessary cuts.

A further reason why TikTok won’t let you cut the sound you want to use is because you may be trying to cut an audio that is already the same length as your video. For example, you have created a 15 second video clip, and you have chosen to attach a 15 second audio.

(Did you know; TikTok users decide within the first second of seeing a video if they want to finish watching it. Your content should therefore grab the viewer as quickly as possible to keep the engagement, and improve the success rate of your upload).

Can I use any sound on TikTok?

Yes, you can use any sound on TikTok, as long as it is one from the apps provided music selection, or it is an original tune directly from you. TikTok has a wide selection of audio’s that you can make use of, so you should not have any issues finding the right sound to include in your video.

If you do not stick to original music when creating your video, there is a possibility that you will use copyrighted music, and your post will be removed by TikTok.

What Happens if You Use Copyrighted Music on TikTok?

If TikTok picks up that your posted video may contain copyrighted music, they can put your upload under review. This means that they will check the audio attached to confirm whether it is copyrighted or not. During this time, your video will not be visible to other TikTok users, and it will not appear on the FYP.

If copyrighted content is confirmed, your video will either be removed, or the audio will be muted so no one will be able to hear it.
