Editorial interest 78/100 Selection signal · not a rating of the site

A macOS utility that checks LTC/SMPTE timecode WAV files for jumps, missing frames, dropouts, and signal problems.

Landing page captured for the 2026-09-19 issue.

For: Playback engineers and show-control technicians
Worth noticing: It decodes every frame locally and reports expected versus received timecode at detected jumps.

Field notes

The homepage describes a frame-by-frame validator rather than a timecode generator. Its checks include drop-frame versus non-drop-frame mode, start and end time, missing or duplicate frames, decode dropouts, clipping, and signal level. The stated workflow is local: users drop in a WAV file and read a report, with no account or upload. The site names Ableton Live, Resolume, QLab, lighting consoles, and broadcast systems as surrounding use cases.
