Loop audio online for free with VoxCraft. Upload a short clip, then either choose how many times it should repeat (2 to 10) or set a target length (up to 20 minutes) and let the tool repeat it until it gets there — no install and no signup on the free tier.
Looping is the quickest way to stretch a short sound to cover a longer section: a few seconds of ambience under a video, a music bed that needs to outlast the narration, a sound effect that should repeat, or a jingle played several times for an intro. In target-length mode the tool does that sum for you and cuts the last repeat exactly at the length you set, so a 30-second clip set to 5 minutes repeats ten times; with a repeat count, the result is simply the clip length times the count.
A repeat is a straight copy placed end to end, so how smooth it sounds depends on the clip. A sound that ends the way it begins loops invisibly; a clip that stops mid-note will click or jump at the join. Trim the clip to a clean start and end first with the trim tool, and use a short fade-out on the final result if you want it to end gracefully.
How it works
- Upload a short clip (MP3, WAV, OGG, M4A or FLAC — 15MB max, 20MB with Pro).
- Pick a mode: repeat a set number of times (2–10), or repeat until a target length in minutes.
- Choose MP3 or WAV and tap Loop.
- Download the single, longer file.
Who uses this
Music beds
Extend a short instrumental so it lasts under a longer voice-over.
Intros and stingers
Repeat a sting for a longer bumper or hold music.
Ambience
Stretch a few seconds of rain, room tone or crowd noise to fill a scene.
Practice tracks
Repeat a phrase or a musical figure several times for practice.
Tips for better results
- For seamless music loops, start with a clip that already ends cleanly on a beat.
- Trim silence off the start and end of the clip first — leftover gaps become audible pauses at every join.
- Target-length mode goes up to 20 minutes for MP3 output (5 minutes for WAV, which is much larger). For something longer, loop the result again.
- Add a fade-out so the last repeat ends smoothly.
Frequently asked questions
How do I repeat an MP3 several times?
Upload the MP3, set the number of repeats with the slider (2–10) and tap Loop. You get one file with the clip repeated that many times.
Can I loop audio to a specific length, like 10 minutes?
Yes — choose "Repeat until a target length", enter the minutes and tap Loop. The last repeat is cut at exactly that length. The maximum is 20 minutes for MP3 output and 5 minutes for WAV.
Max repeats?
10 in repeat-count mode. For longer results use target-length mode, or loop the output again.
How long will the result be?
In repeat-count mode, the clip's length multiplied by the number of repeats. In target-length mode, exactly the length you set.
Why do I hear a click at the join?
The clip doesn't end the way it starts. Trim it to a clean point (ideally at a zero-crossing or after a beat) and try again.
Is it free?
Yes within free-tier limits, with no account required to start.
