Online looper for guitar

Tempo and loop

Microphone input

-inf dB

Do this once per setup: the looper plays four beeps and measures how late your gear hears them. Use the output you play through; if that is headphones, set them next to the microphone for the measurement.

Tracks

Session

Quantized recording: the take starts on the next downbeat after a count in, and the loop closes on its own after the number of bars you chose. Play on headphones, or the microphone also picks up the click and the loops already down. The one exception is the offset measurement: the microphone has to hear the beeps, so set the headphones next to it while it measures.

This is a free online looper. Plug in or sit near your microphone, set a tempo, and record a loop of one or two bars that starts on the beat and closes on its own. Then play over it, or record a second part on the other track. It runs in your browser, with no pedal, no account and nothing to install. It sits alongside the rest of our free guitar tools.

Your first loop in two minutes

1. Measure the offset

Once per setup, press Measure the offset with your speakers on. The looper plays four beeps and works out how late your gear hears them. Then put your headphones on.

2. Set tempo and bars

Type a tempo from 40 to 240 BPM, or press Tap in time, and choose one or two bars. Keep it slow the first time: a loop has to be clean, not fast.

3. Record track 1

Press Record. You hear a count of four, the take starts on beat 1, and the loop closes by itself at the end of the last bar and starts playing back.

Now record track 2 over it, or simply play along. Play and Stop all at the top start and stop every track together.

A two track method for guitar

Two tracks are enough for most practice, as long as each one has a job.

Track Job Try
Track 1 The foundation Open chords strummed evenly, or a palm muted part. One or two bars, steady above everything else.
Track 2 The color An arpeggio of the same chords, an offbeat part, or a short melody. It should fill gaps, not cover track 1.

Then improvise over both, live. If you need a part for track 1, our guitar strumming patterns are written out on an eighth note grid, and our chord progressions page gives you the chords to put them on.

Synced or free

Mode What happens
Synced The first loop you record becomes the master loop. Its tempo and length lock, and every later take starts on the master loop's downbeat, so the two tracks stay together.
Free Each track is its own loop, started when you press Play on it. Useful for an idea that does not sit on a grid, or for a file you imported at another tempo.

In synced mode, the tempo field locks once the master loop exists. To change tempo, start a new session.

What each track does

Control What it does
Record Arms the track. A four beat count in, then the take starts on beat 1 and stops on its own after the number of bars you set.
Play and Stop Start or stop this track alone. In synced mode it comes in at the start of the next loop.
Overdub With overdub on, the next take on this track is layered over what is already there instead of replacing it.
Mute and Volume Silence the track, or set its level from nothing to twice its recorded level.
Drop a file Load a WAV, MP3, OGG or M4A file onto the track instead of recording one.

The microphone panel has an input gain and a level meter. The threshold slider only moves a mark on that meter, which turns green above it: use it to see whether you are playing loud enough, it does not start or stop anything. The metronome button turns the click on or off, with an accent on beat 1 you can set from 0 to 1. The count in before a take sounds either way.

The offset field runs from -100 to 500 milliseconds. A positive value moves a take earlier, for gear that hears you late; a negative one moves it later, if you tend to play ahead of the click.

Save and export

Save keeps the session in your browser: tempo, bars, mode and both tracks. Load the last one brings it back, on the same browser and device. Export the mix (WAV) downloads both tracks mixed into one file, one pass of the loop long.

For a drum beat under your loops, the online drum machine runs in another tab. For a full band playing your chords, the backing track generator does that from the chords you type, and the online metronome is there for tightening a part on a plain click before you loop it.

Frequently asked questions

Is this online looper free?
Yes. It runs in your browser, with no account and no download. The browser asks for the microphone the first time you record, and the audio never leaves your computer.
Why do my loops sound late against the click?
Every computer and audio interface adds a delay between the click you hear and the sound that comes back through the microphone. Press Measure the offset once on your setup: the looper plays four beeps, hears them through the microphone, and sets the offset so your next takes line up. It needs speakers, or headphones placed next to the microphone, because the microphone has to hear the beeps. You can also adjust the offset by hand.
Should I play on headphones?
Yes, for recording. On speakers the microphone picks up the click and the loops already playing, and they end up inside your new take. The only time you want sound in the room is the offset measurement.
How many tracks and bars does it record?
Two tracks, each one or two bars long, at a tempo from 40 to 240 BPM. Overdub lets you stack more than one part on a track, so two tracks go further than they sound.
Can I save my loops?
Save keeps the session in your browser's storage, tempo, mode and both tracks included, and Load the last one brings it back on the same browser. Export the mix (WAV) downloads both tracks mixed together as one pass of the loop, ready to share or to drop into a recording program.
Can a looper replace a loop pedal?
At home, for working out a part or a song idea, yes, and it costs nothing. On stage a pedal is still easier: you work it with your foot, and it does not depend on a computer. Plenty of guitarists sketch a loop arrangement here and then rebuild it on their pedal.

Who made this

Guitar Social Club is the work of Yohann Abbou, a guitar teacher in Paris. He teaches adults, which shapes everything here: people with jobs, limited practice time and a clear idea of the songs they want to play. A looper makes the most of that time, because hearing your own part back is the fastest way to know whether it is in time. None of the tools asks you to sign up before it works, and the rest of our free guitar tools work the same way.
