sft.ltc~

A simple Max external for encoding and decoding SMPTE timecode (LTC).

• Switch between auto, encode, and decode mode.
• Set the timecode via hours, minutes, seconds, frames — or directly in milliseconds.
• Supports the most common framerates:
  • 23.97 fps
  • 24 fps
  • 25 fps
  • 29.97 fps
  • 29.97 fps (DF)
  • 30 fps.
• Outputs both the raw LTC signal and the decoded timecode list (hh mm ss ff fps drop).

Great for syncing audio, video, lights, or testing SMPTE workflows inside Max.

⚠️ Note: In Max, audio is pull-based — make sure the LTC input is also routed to an audio object (like dac~, meter~, or record~) so that decoding works properly.

Built on the libltc library by Robin Gareus and derives from a Max external by Matthias Kronlachner, originally inspired by work from Mattijs Kneppers.
