WLED Audio Sender
Last updated: April 18, 2026
WLED Audio Sender is an open-source application that captures audio from your device’s microphone and sends it over your local network to WLED-compatible LED controllers for real-time audio-reactive lighting effects.
We do not collect, store, or transmit any personal data.
The app requires microphone access solely to:
Audio data is processed entirely on your device and is never recorded, stored, or sent to any external server. Audio samples exist only momentarily in memory during real-time processing.
The app sends UDP multicast packets exclusively to your local network (default address 239.0.0.1:11988). These packets contain only audio analysis data (volume levels, frequency bins) — no raw audio is transmitted.
No data is sent to the internet.
The app does not include any analytics, telemetry, crash reporting, or tracking of any kind.
The app does not use any third-party services that collect user data.
The app stores only your preferences (multicast address, port, and gain control settings) locally on your device using the standard platform preferences API. No data is stored externally.
The app does not collect any data from anyone, including children.
Any changes to this privacy policy will be posted on this page with an updated date.
