Snickometer — Classic Snicko
The original -detection tool.
How It Works: A single stump-microphone feed is displayed as a rolling waveform. When the ball passes the bat, viewers see whether a sharp audio spike coincides with the video frame.
Snicko vs : Snicko is a broadcast-only graphic; is the -approved, calibrated evolution that's synchronised to sub-frame accuracy and used for match decisions.
Limits: Not accepted for third-umpire decisions in most competitions — its waveform is not calibrated tightly enough to time to the frame of ball-passing-bat.
Technical Breakdown
19-section schemaDefinition
The Snickometer ('Snicko') is the original oscilloscope-style graphic developed by Allan Plaskett and introduced by Channel 4 in 1999, showing a real-time sound waveform alongside slow-motion video.
Tactical Use
Commentators use Snicko to explain marginal calls to viewers; in-match decisions still rely on + Hot Spot.
