If this FAQ does not answer your questions, feel free to check out the about page for more information.

How can I shorten a song without cutting it?
Submit a song to Audjust and enter the new duration of the song. You can then choose from multiple results that match your requested length. This is helpful if you need to shorten a song to match a video you already edited.
How can I make a song longer seamlessly?
Upload your song to Audjust and type in a longer target length. Instead of looping the whole track back to the start, it repeats sections on natural beats so the longer version flows as one continuous piece, then you preview and export it. The same tool can also shorten a song, just enter a length shorter than the original.
How is this different from Adobe Premiere Pro's Remix?
It's available without download or need to pay. You can also mark parts of the song you dislike and have them removed, giving you more control. You can find more information on our blog: Audjust vs. Adobe Remix
How can I find perfect loops of a song for an edit?
Upload the song to Audjust and let it analyze it. Below the song preview, a list of loops will show and you can select one to download. You can use this loop as background for videos or for an edit.
Is there an easy way to find a loopable sample for FL Studio or Ableton?
Upload the song you want to sample to Audjust and it will show you a list of loops in the song (including start and end times). You can then select it to download the loop.
How can I remove a part of a song without it sounding weird?
You can use Audjust to remove a part of a song seamlessly! After adding it, select the part or parts that you don't like and the algorithm will remove them and try to keep the edit sound natural and without cuts.
How do I shorten a song online for free?
Audjust allows you to shorten (or lengthen!) any song to whatever length you want for free. You can use the website without installing or downloading another app or program.
How can I make a perfectly looping version of a song for TikTok, Instagram Reels, or YouTube Short?
After you upload the song to Audjust, you can drag to select the part you want to loop. Click "repeat" in the menu, choose a result with the loop icon, click export, then select the option to just download the loop.
Is Audjust free to use?
Yes. You can shorten, lengthen, and loop songs for free without an account. Some advanced features are part of an optional premium upgrade.
What audio file formats does Audjust support?
Audjust works with MP3, WAV, M4A, and most other common audio files. Upload the file you want to edit and Audjust analyzes it for you.
Do I need to download or install anything?
No. Audjust runs in your browser, so there is nothing to install and no app to download. It works on both desktop and mobile browsers.
Will my song still flow naturally after editing?
That is the goal. Audjust makes its cuts and joins on the song's beats and section boundaries, so a shortened or extended track avoids the abrupt cuts and awkward fade-outs you usually get from trimming.
