The Fix

Go from guessing millisecond offsets to scientific precision. Calculate the exact delay needed for your specific setup.

Precision Interface

FPS Detection

Automatically detects video frame rates for exact time mapping.

Audio Peak

Transient peak detection marks the exact millisecond of impact.

Waveform Zoom

Frame-by-frame scrubbing for forensic-level sync verification.

Privacy First

100% browser-side. Your test videos never leave your machine.

Technical FAQ

How does the calculation work? +
Load a test video of a “clap” or “snap.” The tool identifies the frame of touch and the audio spike. The difference (in ms) is your offset.
What is FPS Detection for? +
Sync is dependent on video timing. By detecting your recording FPS, we ensure the time-stamps align perfectly with video frames.
Do I need special hardware? +
No. Any camera and mic setup will work. Just record a short test clip and drop it in.
Is it better than manual guessing? +
Yes. Manual guessing often misses by 30-50ms. Our tool gets you to the single-digit millisecond range.
What if my offset varies? +
Hardware can have slight drift. We include a “Running Average” feature to smooth out minor variances across multiple tests.
Where do I put the result? +
Copy the result and paste it into OBS > Advanced Audio Properties > Sync Offset (ms).
Is my video uploaded? +
Never. All processing happens in your browser’s memory using localized storage. We don’t have servers for your video data.
Does it work for 4K video? +
Yes. It handles any resolution supported by your browser’s video engine, including 4K with high bitrates.
