LipSync Test Tool
Sync Audio to Video
$8.99
Catch sync drift before air: test patterns, beeps & flash, timecode display, optional two-phone latency in ms/frames—built for control rooms, trucks & streaming.
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
• Interface – Dark, minimal UI for dimmed galleries, OB trucks, and fast orientation changes.
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.
