Your file never leaves your device. Processed locally in your browser. Nothing is uploaded.

Short files only: up to 30 seconds in, and 60 seconds out. GustKit repeats the sound with FFmpeg aloop, then tries concat if that fails.

How to loop a short audio file

1. Drop one audio file you already have. Video and pictures are refused here. 2. Leave 2 times, or pick more plays. Switch to a target length when you need the file to last a set number of seconds. 3. Press “Loop audio” and play the download from the start.

GustKit runs FFmpeg aloop in this tab and re-encodes the file. If that fails, it concatenates the same file. WAV stays WAV and MP3 stays MP3. The sound repeats from the start. Loop video does the same job for a short clip. This page takes audio only.

A loop is not a longer fade

Add silence inserts quiet time and does not repeat the recording. Change audio speed stretches or shortens one play. Merge audio joins different files. This page repeats one file. A file longer than the limit on the page is refused, because the whole file is re-encoded here.

The audio stays in this tab

The first visit downloads FFmpeg. Later visits reuse the browser cache. GustKit does not fetch audio from a link. Close the tab and the file is gone.

How to hear the repeat before you replace the original

1. Play the download from the start. With 2 times, the opening should come back once. 2. Check the length. It should be about twice the original, or close to the target length you typed. 3. Keep the original until the repeat lands where you expect.

Loop video repeats a short clip. This page repeats audio only. The file type stays the same. Nothing is uploaded.

Frequently asked questions

The download is about twice as long. Did 2 times work?

Yes. Two plays are about twice the original length. The first second of the original is still the first second, and it comes back again.

Can I loop until a clock time?

Yes. Switch Repeat by to a target length and type the seconds. The result stops at that length, even if the last play is cut.

Why is a long recording refused?

The whole file is re-encoded in this tab. Trim it under the limit shown on the page, then loop that piece.

Is the audio uploaded?

No. FFmpeg runs in this tab.

The file is longer and the opening comes back. Did the loop work?

Yes. Each extra play adds about the length of the original, unless you set a target length that cuts the last play.

Can I loop the audio and also change the volume in one step?

No. Loop it first, or change the volume first, then open the other page on the download.
