LTC WAV Export

LTC WAV Export generates a standalone audio file containing an LTC signal. Use it to burn timecode onto tape, populate a DAW timeline with an LTC reference track, or create a playback file for a device that does not connect directly to LTCast.

Accessing LTC WAV Export

Choose File → Export LTC WAV, or click Export LTC WAV in the Tools tab.

Export parameters

Configure the following options before exporting:

• Start Timecode — the SMPTE address at which the generated LTC begins. A common choice is 00:59:58:00 for a 2-second pre-roll before 01:00:00:00.
• Duration — how many seconds of LTC to generate. Set this to the full length of the show segment plus any desired post-roll.
• Frame Rate — 24, 25, 29.97 DF, or 30 fps. Must match the frame rate of your show.
• Sample Rate — 44100 or 48000 Hz. Match the sample rate of the target system (DAW project, tape machine, or playback device).
• Amplitude — the peak level of the LTC signal in dBFS. -3 to 0 dBFS is typical; consult your console documentation if it specifies an input level for LTC.

Exporting

Click Export. LTCast generates the WAV file offline (no audio plays during generation). When complete, a save dialog appears. Choose a save location and file name.

Output format

The exported file is a stereo WAV with LTC on one channel and silence on the other. This allows a DAW to route the LTC channel to a timecode output while leaving the silence channel available for music or other content if needed.
