LipSync Test Tool
Sync Audio to Video
$8.99
New QR anchor for long-latency sync tests. Enable QR on the pattern device, keep it in the camera view, and measure flash-to-beep delay precisely — even above 500 ms.
Measure - don't guess!
Lip Sync is a precision tool for broadcast engineers, live production teams, and OB/streaming operators who need to verify and correct end-to-end AV sync across monitors, routers, encoders, and playout—before you go live or between segments.
Key features
• Visual & audio test pattern – On-screen markers, beeps and flash cues so lip offset is obvious in control rooms.
• Customizable setup – Match FPS and tone frequency to your line standard or show format.
• Real-time feedback – Clear Sound early / Video early indicators plus timecode-style readouts in portrait and landscape for quick checks at the desk or in the truck.
• Event log – Recent sync-related events in one place for handover notes or troubleshooting during a show.
• Latency measure mode – Point a second iPhone (camera + mic) at the program monitor for an end-to-end delay readout in milliseconds and frames.
• QR anchor for long delays – Enable QR on the pattern device for frame-guided flash/beep pairing when latency exceeds 500 ms—accurate measurements on high-latency paths up to several seconds.
• Live measurement mode – Keep measuring after the first result; the offset updates continuously until you tap Stop—ideal for watching drift during line checks or while routing changes settle.
• Measurement history – Recent latency results saved in the Measure screen for quick comparison across runs, formats, or signal paths.
• Interface – Dark, minimal UI for dimmed galleries, OB trucks, and fast orientation changes on iPhone and iPad.
Why Lip Sync?
In live shows and broadcast, sync drift shows up as complaints, replays, and lost trust. Lip Sync gives you a repeatable, end-to-end check you can run on any path—not guesswork in the heat of a production.
Ideal for broadcast facilities, live sports and entertainment, houses of worship with IMAG, corporate live events, streaming ops, and systems integrators commissioning live signal chains.
