StreamSync

Synchronize two video tabs using shared audio, processed locally in your browser.

StreamSync synchronizes videos in two Chrome tabs using shared audio. This is a beta release for early users. Watch a main broadcast with commentary from another source, or align two recordings of the same event. When both tracks contain shared audio, StreamSync can find the delay and adjust playback. Getting started: 1. Play both videos. They need a shared audio segment and an initial delay of no more than 45 seconds. 2. Open StreamSync on the first tab and connect it as the main stream. 3. Switch to the second tab and click the StreamSync icon. It connects as the additional stream and enables Auto sync. 4. Wait for a match. Turn Auto off if you prefer to use the Sync button. Features: • Automatic and manual synchronization. • Reference stream selection and separate audio output controls. • Audio capture and processing continue when the extension popup is closed. • Stream status, session restart and stop controls. • Interface available in ten languages. Privacy: Audio is compared in browser memory and is not sent to the developer. StreamSync does not use your microphone. Tab titles, URLs and icons are used to display sources and the extension's status. Preferences are saved locally. Loading a page icon may make a request to the corresponding website. StreamSync has no advertising, analytics or account registration. Please note: Both tracks need distinguishable shared audio. Loud speech over a quiet background, different audio tracks or player restrictions may prevent synchronization. The extension uses accessible HTML video players; compatibility with every website, DRM system or live playback mode is not guaranteed. Selected F1 TV and VK Video scenarios have been tested, including recordings with Track FX on F1 TV. These services may require their own accounts and subscriptions. StreamSync does not provide content access or bypass website restrictions. StreamSync is independent and is not affiliated with these services. Click Stop session when you finish. A website error may require reloading the page and reconnecting it. While a correction is active, the player code notices trusted pointer and keyboard input on the connected page to cancel the correction when you intervene. It does not read or record which key was pressed, typed text, pointer coordinates or a click history. Only the technical cancellation state is held in memory; it is not sent to the developer.
