Audio Looper – Loop and Extend Audio

Repeat a clip a set number of times or to a target length, with a crossfade.

Your files are processed on your device and are never uploaded.

Repeat a song, a beat or any sound as many times as you want – or until it reaches a set length, such as 30 minutes or 1 hour. The looper can repeat the whole file or just one part of it, and blends each repeat into the next with a short crossfade so you do not hear a jump.

How to Loop Audio

  1. Choose your audio – MP3, WAV, M4A or the sound of a video.
  2. Pick how to repeat: Repeat a number of times (enter the number of loops) or Extend to a length (enter the target length in minutes).
  3. Choose the part to loop with Loop from and Loop to, if you only want a section such as a chorus or a drum beat.
  4. Smooth it out: Set a crossfade between repeats and an optional fade out at the end.
  5. Download the looped file.

What People Loop

  • Background music for a video, slideshow, livestream or game that is longer than the song
  • Sleep and study sounds – rain, waves, lo-fi beats – extended to one, two or eight hours
  • Practice tracks: a difficult passage of a song, repeated so you can play along
  • Beats and drum loops for rapping, singing or dance practice
  • Hold music and shop background audio

Getting a Seamless Loop

A loop sounds smooth when its end matches its start. For music, set Loop from and Loop to on the first beat of a bar, so the rhythm continues without a stumble. For sounds like rain or noise, a crossfade of 1–3 seconds hides the join completely. For a beat that already loops perfectly, set the crossfade to 0.

Adding a fade out at the end makes the final repeat finish gently instead of stopping abruptly.

Free, Fast and Private

The looping happens in your browser, so even long files are created without an upload. Your audio stays on your device. If you need ambient sound for sleep, you can also generate it endlessly with the White Noise Generator.

Frequently Asked Questions

How do I loop a song for 1 hour?
Choose the song, select Extend to a length, enter 60 minutes and download. The song is repeated until the file is one hour long.
Can I loop only part of a song?
Yes. Set Loop from and Loop to to the seconds where the part starts and ends, and only that part is repeated.
How do I stop the loop from clicking or jumping?
Add a crossfade of 1–3 seconds between repeats, or start and end the loop exactly on a beat.
What is the longest file I can make?
Several hours is possible on a computer. Long WAV files become very large, so choose MP3 for long loops.
