Locator Metadata WAV Exporter

Ableton Live Extension that renders an Arrangement selection and writes WAV cue marker metadata from locators.

Requirements

• Ableton Live Suite with Extensions SDK support.
• Ableton Extensions SDK 1.0.0-beta.0.
• Node.js compatible with the Ableton Extensions CLI.

Behavior

• Run from an AudioTrack Arrangement time selection.
• Uses the selected time range as the rendered WAV range.
• Writes every locator inside that range as a WAV cue marker.
• Writes each locator name into the WAV LIST/adtl labels.
• Writes the marker WAV to this extension's private storage folder.

Use

1. Select an Arrangement range on an audio track.
2. Place locators inside the selected range.
3. Right-click the selected range on the audio track.
4. Choose Export WAV With Locators.

The Extension uses renderPreFxAudio(), so it renders the selected audio track pre-effects. The exported file path is printed to the extension log.

Output Location

The exported WAV is saved in the extension's private storage folder. This is a per-extension folder managed by Ableton Live, not the same folder as your Live Set, Downloads folder, or Desktop.

After exporting, check the extension log for a line like this:

Exported locator WAV: /path/to/render-locators.wav

That log line shows the exact file path to the rendered WAV.

Setup

Download the Ableton Extensions SDK from Ableton and copy these two archives into vendor/:

• ableton-extensions-sdk-1.0.0-beta.0.tgz
• ableton-extensions-cli-1.0.0-beta.0.tgz

Then install dependencies:

npm install

Development

npm run build
npm run package

The package command creates locator-metadata-wav-exporter.ablx.

This repository does not redistribute the Ableton Extensions SDK archives. Get them from the official Ableton SDK download.
