Frequently Asked Questions

What is LTC timecode?

LTC (Linear Timecode) is an audio-encoded SMPTE timecode format used in live production, film, and broadcast to synchronize multiple devices — lighting consoles, video servers, DAWs, and more.

Do I need special hardware?

No. The tool generates downloadable WAV files. Route through any audio output or interface to a timecode reader.

How do I use LTC in my show?

Route the WAV into a spare output on your playback rig (QLab, Ableton, Reaper). Feed that into a timecode reader like a grandMA2/grandMA3 or ChamSys console. It chases the timecode and fires cues automatically.
