Audio Looper Online
Pi7 Audio Tool - Repeat or extend any audio clip with a smooth, seamless crossfade.
Advanced Options
Need a track that loops cleanly for a meditation session, a video background, a focus playlist, or a sound-design bed? Pi7 Audio Looper repeats your audio or extends it to any target length with a smooth crossfade between repetitions, so the seam is inaudible.
It runs entirely in your browser. No upload, no signup, and no waiting in a queue.
How to Loop Audio in 3 Easy Steps
- Select or drop your audio file (MP3, WAV, M4A, OGG, FLAC and more)
- Pick how to loop: repeat a fixed number of times or extend to a target length in minutes
- Adjust the crossfade slider for a seamless seam, then click Create Loop
That is it. The looped file is built locally and downloaded instantly.
Why Crossfade Matters
Most clips do not start and end on identical waveforms. When you concatenate copies back-to-back, the mismatch creates an audible click or pop at every seam. The crossfade slider blends the end of one repetition into the start of the next over a small window, hiding the seam completely. For most music and ambient material, 0.3 to 1 second works well. For drum loops cut to the bar, 0 (no crossfade) keeps the rhythm tight.
Pro Use Cases
- Meditation and sleep tracks: extend a 2 minute ambient loop to 30 minutes or 1 hour
- Music producers: grab a 4 bar phrase and loop it as a sample for your DAW
- Game and film sound design: build seamless room tones, ambient beds, and SFX loops
- Podcasts and broadcast: stretch a music bed to fill an exact segment length
- Content creators: fit a background track to the length of your video
- Live streamers: build long intro, outro, and wait-screen audio
- Educators: repeat a phrase a fixed number of times for language drills
Advanced Controls for Tighter Output
- Trim source: set start and end points so you loop a specific segment of your file, not the whole thing
- Master fade in: add a smooth ramp at the very beginning of the looped output
- Master fade out: add a smooth tail at the very end of the looped output
- Output format: MP3 at 192, 256, or 320 kbps, or lossless WAV for full fidelity

Is It Safe to Loop Audio Here?
Yes. The whole pipeline runs in your browser using WebAssembly. No file is uploaded, nothing is stored on a server.
Can I Loop a Video to Make a Long Audio Track?
Use the Extract Audio from Video tool first to pull the audio out of your clip, then drop the extracted file into the Audio Looper.
Is There a Limit on Loop Count?
The looper supports up to 60 repetitions per pass. For very long extensions, increase the source length first by trimming a longer segment, or run the loop in two stages.
