Audio Bluetooth Sync by Guru

Audio Bluetooth Sync solves the common problem of audio-video desync when using Bluetooth headphones or speakers. Many Bluetooth devices introduce a noticeable latency (typically 100–300 ms) that causes the audio to lag behind the video. This extension lets you compensate for that delay by adding a configurable offset to video playback.

How it works: It hooks into the MediaSource API and adjusts the timestampOffset for video buffers, effectively delaying the video track so that it aligns perfectly with the audio coming from your Bluetooth device. The default delay is set to 150 ms, which works well for most modern Bluetooth headphones, but you can fine-tune it from 0 to any value in milliseconds using the popup interface.

Key features:
- Simple number input to set delay in milliseconds.
- Changes are saved locally in your browser's storage.
- Works on all websites that use MediaSource
- Lightweight – no background processes, minimal resource usage.

To use: Click the extension icon in the toolbar, enter your desired delay (e.g., 150), and click Save. The current page will reload to apply the new setting. All other open tabs will also update upon their next reload.

Whether you're watching movies, gaming, or listening to music, Audio Bluetooth Sync ensures your audio and video stay in perfect harmony. Adjust once and forget.
