Overview

Audio Groove Quantizer detects transients in a loop and moves them toward a quarter-, eighth-, or sixteenth-note beat grid, a straight or swing template, or a reference audio groove. Choose the tempo, quantize amount, detection sensitivity, and output format, then download the retimed audio file.

When to use

Tighten uneven drum or percussion hits against a defined BPM and note grid.
Apply light or triplet-like swing to a straight loop while preserving pitch.
Transfer the timing feel of a reference loop to another audio loop.

How it works

1Upload the loop audio and enter its tempo in BPM.
2Select a quarter-, eighth-, or sixteenth-note grid and choose the quantize amount.
3Choose a straight grid, 54% swing, 66.7% swing, or reference audio groove; upload a reference loop when using the reference option.
4The tool detects transients, retimes marker-bounded segments, joins them, and returns an audio file with timing metadata.

Use cases

Correct loose timing in drum, percussion, and rhythmic loop recordings.
Create consistent straight or swung grooves for beat-making and arrangement work.
Match the timing feel of one loop to a reference performance.

Examples

1. Tighten an uneven eighth-note drum loop

Beat producer

Background

A beat producer has a drum loop with hits that fall slightly before and after the intended eighth-note positions.

Problem

The loop needs a tighter rhythm without changing its pitch.

How to use

Upload the drum loop, set the tempo to 120 BPM, choose an eighth-note grid and a straight grid, then render the result as WAV.

Tempo: 120 BPM; Grid: Eighth notes; Quantize amount: 100%; Groove target: Straight grid; Detection sensitivity: Medium; Output: WAV.

Outcome

Detected hits are pulled fully toward the 120 BPM eighth-note grid and returned as a WAV file with timing metadata.

2. Add swing to a straight percussion loop

Music producer

Background

A producer has a straight percussion loop and wants a more relaxed, swung rhythmic feel.

Problem

The loop sounds mechanically straight and needs controlled timing variation.

How to use

Upload the loop, enter its BPM, select an eighth- or sixteenth-note grid, choose Light swing (54%) or Triplet-like swing (66.7%), and adjust the quantize amount.

FAQ

What audio can I upload?

The tool accepts audio files through the audio input. Individual uploads can be up to 100 MB.

Which beat grids are available?

You can use quarter-note, eighth-note, or sixteenth-note grids.

Can I control how strongly the loop is quantized?

Yes. Set the quantize amount from 0% to 100%.

Which groove targets are supported?

Supported targets are a straight grid, 54% light swing, 66.7% triplet-like swing, and a reference audio groove.

What output formats are available?

You can export the retimed loop as MP3, WAV, FLAC, M4A, or OGG Vorbis.

Grid: Eighth notes; Groove target: Light swing (54%); Quantize amount: 60%; Detection sensitivity: Medium; Output: WAV.

3. Transfer timing from a reference groove

Audio editor

Background

An audio editor wants one loop to follow the alternating timing feel of another loop.

Problem

A straight or built-in swing template does not match the desired reference performance.

How to use

Upload the source loop, choose Reference audio groove, add the reference loop, set the tempo and grid, and select an output format.

Groove target: Reference audio groove; Grid: Eighth notes; Quantize amount: 100%; Detection sensitivity: Medium; Output: FLAC.

Outcome

The source loop is retimed using timing residuals detected from the reference groove and exported as a FLAC file.
