What Is a Looper, and Why Is It Fun?
A looper records a short piece of sound and plays it back in a repeating loop, while you record more layers on top. Beatboxers build entire songs this way: first a drum beat, then a bass line, then chords, then a melody, all stacked live. Guitarists do the same with pedals that cost real money. This free browser tool gives you the same idea with nothing to buy and nothing to install: your microphone, your browser, and as many layers as you like.
The tool is honest about what it is. It is a practice and creativity toy, not a studio recorder. It records through your browser microphone, stores each layer in memory on your own device, and loops the layers together. Nothing is uploaded to any server, and nothing is saved after you close the page. That also means there is no multi-track editing, no effects rack, and no cloud backup. What you get is the joyful core of looping: record, stack, listen, repeat.
How to Record Your First Loop
Press Record a layer and allow microphone access when your browser asks. Clap a steady beat for a few seconds, then press Stop recording. That first layer sets the feel of everything that follows, so keep it steady. Press Play loop and your beat repeats. Now press Record a layer again and hum or play over the beat. Stop, and the new layer joins the loop. Add a third layer, a fourth, and suddenly you have a song built from your own sounds.
Layers of different lengths loop independently. A two-second beat and a four-second melody will line up every four seconds, which creates gentle variation as the loop turns. If you want tight alignment, try to make each layer the same length, or close to it. Count yourself in before you start recording, and keep the tempo steady. Looping rewards rhythm more than fancy playing: a simple, steady layer sounds better than a complicated, wobbly one.
If the Microphone Is Blocked
Browsers guard the microphone carefully, and they should. If you denied access earlier, the browser may keep blocking it until you change the site permission. Look for the microphone icon in your address bar and allow access for this site. If you are on a device with no microphone, or you simply do not want to grant access, press Add a demo tone layer instead. The tool creates a clean synthesized tone layer so you can still try looping, stacking, and clearing layers. It cannot record your voice, but it lets you learn the workflow.
Recording quality depends on your device. A phone microphone in a quiet room gives a clear result. A laptop microphone across a noisy room gives a distant, echoey one. Get close to the microphone, reduce background noise, and avoid shouting, which distorts. If your layers sound muddy, record fewer layers at lower volume rather than many loud ones stacked together.
Ideas for Practice and Play
Use the looper to practice rhythm. Record a metronome-like clap pattern, then practice scales or chords over it. Use it to test harmonies: sing one note, loop it, then sing a third above it and hear the harmony in real time. Use it to write songs: loop a chord pattern by humming, then try three different melodies over it and keep the best one. Teachers use loopers to show students how parts fit together, because hearing your own part repeated makes mistakes and good ideas equally obvious.
Kids love loopers too, because the result is instant. A clap, a hum, a whistle, and suddenly they have made a piece of music. There is no wrong answer, and clearing the layers to start again costs one click. That low-stakes feeling is exactly what makes looping a great first step into music making.
How the Technology Works
When you press record, the browser captures audio with MediaRecorder and stores it as a small audio file in memory. When you stop, the tool decodes that file into raw audio samples and keeps them as a layer. When you press play, each layer is handed to the Web Audio system as a looping buffer source, so all layers start together and repeat until you stop them. All of this happens on your device, in your browser, with no server involved.
Frequently Asked Questions
Why is there a delay before my layer starts? Browsers need a moment to start the microphone and the audio system. Keep your first beat steady and the delay stops mattering after the first loop.
Can I download my loop? This version focuses on live looping rather than exporting. Record your loop with your device screen recorder if you want to keep a performance.
Does it work on a phone? Yes, in a modern mobile browser, with microphone permission granted. Use headphones to avoid feedback, where the microphone picks up the loop from the speaker and re-records it.
Start with one simple layer, stack a second, and enjoy hearing yourself become a one-person band.
