The ACCurate Syncer por Isaac Murtagh

If you've ever tried listening to live radio commentary while watching a sports stream, you know the pain — radio is 20 to 60 seconds ahead of TV. Commentary spoils every try, every goal, every big moment before you've seen it happen.

The ACCurate Syncer fixes this. It delays the iHeart Radio live stream so the audio lines up with what's actually on your screen.

How it works:
1. Open a live stream on iHeart Radio and hit play
2. Click the extension icon to open the syncer
3. Hit pause — the audio mutes and a timer starts counting
4. Wait until the commentary matches your TV picture (usually 20-40 seconds)
5. Hit play — the stream rewinds by exactly how long you waited

That's it. Audio and video are now in sync.

Need to adjust? Use the +5s and -5s nudge buttons to fine-tune the delay. Hit the On Air button to jump back to live at any time.

Built for the Alternative Commentary Collective (ACC) on iHeart Radio, but works with any live stream on the platform. No accounts needed, no data collected, everything runs locally on your device.
