This situation may be due to the platform's automatic rules regarding copyright and content length.
In this guide, we explain the two main reasons why TikTok mutes the audio on your posts.
Account Type: Business vs. Creator
TikTok classifies accounts into two large groups:
Content Creator Accounts
You can use music from TikTok's general catalog.
They have more freedom to use popular sounds or trends.
Commercial or Brand Accounts
They may only use music authorized for commercial use .
If you post a video with music you don't own the rights to , TikTok automatically mutes that content.
Important : TikTok doesn't offer a traditional "whitelist" system. Instead, it works with a safe list , where rights holders can specifically authorize certain business accounts to use their music.
Are you an artist or label? UMW Recordings Inc. can help you request the use of your music on verified or branded accounts.
Video length: Maximum 60 seconds with music
TikTok imposes a length limit on videos containing copyrighted music:
If your video is longer than 60 seconds , TikTok may automatically mute the audio, even if you're using your own song.
This is a measure of protection of licenses and rights.
✅ Recommendation
Keep your music videos under 60 seconds if you're not using original audio recorded directly in the app.
