## Overview

A local swing timing processor for drum and rhythmic loops. The tool detects energy onsets, anchors the first transient, and shifts alternate eighth- or sixteenth-note grid positions to the requested swing percentage. At 50% the grid stays straight; higher values delay the offbeat. A deterministic seed controls bounded random timing variation, and FFmpeg retimes the marker-bounded audio segments while preserving pitch as far as its tempo filters allow.

## Inputs

- **Loop audio** (file)
- **Tempo (BPM)** (number)
- **Subdivision** (select)
- **Swing (%)** (number)
- **Amount (%)** (number)
- **Humanize (ms)** (number)
- **Random seed** (number)
- **Detection sensitivity** (select)
- **Output Format** (select)

## When to use

- Add shuffle or triplet-like movement to a straight drum loop.
- Apply lighter or stronger swing to an eighth- or sixteenth-note rhythm.
- Introduce repeatable timing variation with optional seeded humanization.

## How it works

- Upload an audio loop and enter its tempo in BPM.
- The tool detects energy onsets and anchors the first transient.
- Alternate positions on the selected eighth- or sixteenth-note grid are shifted toward the chosen swing percentage.
- FFmpeg retimes marker-bounded audio segments and returns the selected output format.

## Use cases

- Give straight drum loops a classic 66.7% eighth-note shuffle.
- Shape sixteenth-note percussion with controlled, partial swing.
- Compare clean quantized timing with subtle, repeatable humanized variation.

## Frequently asked questions

### What kind of audio can I use?

Use an audio file containing a transient-driven drum or rhythmic loop.

### What does the swing percentage control?

It controls how far alternate grid positions are delayed. At 50%, the timing stays straight; higher values create more swing.

### What is the Amount setting?

Amount controls how strongly the selected swing timing is applied, from 0% to 100%.

### Can I add humanization?

Yes. Set Humanize to a value from 0 to 25 ms for bounded random timing variation. A random seed can make the result repeatable.

### Which output formats are available?

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