How to make a looped audio file

Create a reusable sound loop in three steps, with no sign-up or software installation.

  1. 01

    Add audio

    Drop in a file or choose music, ambience, or a sample from your device.

  2. 02

    Choose the range

    Drag either waveform handle, or enter start and end times for precise selection.

  3. 03

    Preview the join

    Listen to the selection and tune the crossfade. A short fade often removes clicks at the loop point.

  4. 04

    作成してダウンロードする

    Choose the repeat count, create the WAV, then preview and download it.

一般的な使用例

Audio loops are useful anywhere a sound bed needs to run continuously and consistently.

Short-form video backgrounds

Make a background segment that can match the duration of a Reel, Short, ad, or product demo.

Games and app sounds

Create smoother ambient beds, menu music, and reusable sound samples.

Podcasts and live streams

Generate looping intros, transitions, or holding-screen music, then combine it with spoken audio.

Meditation and white noise

Let rain, waves, and focus music return gently to the beginning instead of ending abruptly.

Privacy: your audio is never uploaded

The file is read, decoded, and exported in this browser tab. Closing or refreshing the page removes local previews and generated download links; your source audio is not sent to a server.

FAQ

Audio looping FAQ

Will this upload my audio?

No. Selection, preview, and export all run locally in your browser.

Why is the output WAV?

WAV is lossless and broadly compatible, which makes it a good choice for further editing, mixing, or uploading elsewhere. Convert the download afterward if you need MP3, M4A, or OGG.

What crossfade should I use?

Start around 0.03 to 0.15 seconds and listen. Ambient sounds and music often benefit from a short fade; use 0 for material that needs an exact beat.

Can I loop the full audio file?

Yes. Leave the start at 0 and the end at the full duration, then choose a repeat count.

Is there a size limit?

Input files can be up to 500 MB. To keep browser processing reliable, generated WAV files are capped at about 1.5 GB and the editor shows an estimate before you start.
