What is Ultra Edge technology in Cricket?
Cricket uses UltraEdge technology, which uses real-time ball tracking and sound analysis to help make more accurate choices about dismissals, especially for LBW (leg before wicket) and caught-behind appeals.
For finding edges, Ultra edge is a more advanced form of Snickometer. British computer scientist Allan Plaskett came up with the idea for the Snickometer in the UK and used it in 1999.
The International Cricket Council (ICC) found the cutting-edge technology to be safe to use after testing and making sure it was correct. Engineers at the Massachusetts Institute of Technology (MIT) have put this system through many tests.
Mics are put inside the stumps, and different cameras are set up on the field and around the ground for this technology to work. When a ball hits a bat, it makes a certain sound that the wicket mics pick up, and the tracker screen shows.
It is common for UltraEdge to work with the Decision Review System (DRS). It uses cameras and microphones set around the field to track the ball. The system keeps track of the ball’s path and records sound waves, which help determine if the ball hit the bat or anything else before it was caught or hit the stumps.
The goal of adding this technology to Cricket is to improve decision-making and cut down on human error, especially when it’s hard to see clearly what will happen with an on-field choice.
How does Ultra Edge technology work in Cricket?
For Cricket, UltraEdge technology mostly uses a lot of carefully placed cameras and microphones around the field to record sound and video. To make things easier to understand, here’s how UltraEdge works:
1. Ball Tracking Cameras:
Around the cricket field, high-speed cameras keep an eye on the ball at all times.
These cameras take many pictures every second, which lets us get a good look at the ball’s path and direction.
2. Microphones:
You can also find sensitive mics near the stumps and other important spots on the field.
Music comes from these microphones, like when the ball hits the pad or other equipment or goes by the bat.
3. Data Integration:
Real-time data integration from the ball-tracking cameras and mics gives a full picture of how the ball interacts with the bat and other parts.
4. Software for analysis:
Specialized software works on the combined data to ensure the audio and video sync.
To find out exactly when the ball hit the bat or other object, algorithms look at the frames from the cameras and the audio signals that go with them.
5. Display of Results:
The analyst then shows the third judge or on-field umpires the results, which are usually in the form of a graph that shows when and where the ball hit the ground.
Who invented Ultra Edge, and when did Cricket start using it?
DRS (Decision Review System) made UltraEdge, a system that is part of the larger DRS used in Cricket. Individuals did not create DRS or UltraEdge. Instead, it developed over time as technology improved and people worked together.
The International Cricket Council (ICC) officially adopted the Decision Review System in Test cricket in 2008. It includes technologies like Hawk-Eye, which tracks the ball, and UltraEdge, which tracks the sound. The goal was to cut down on umpiring mistakes and make choices made on the field more accurate.
People usually talk about something other than who invented or developed UltraEdge, which results from technical advances and help from many companies and sports technology experts.
DRS, including UltraEdge, has been used in other types of Cricket since it was first introduced in Test cricket. It is now also used in One Day Internationals (ODIs) and Twenty20 Internationals (T20Is), and different cricket boards use it for their games and tournaments.

Use Of Snickometer For Ultra Edge Review In Cricket
Snickometer, commonly known as Snicko, is a system used in cricket to determine whether the ball edged[a] the bat, for a potential dismissal such as a catch or leg before wicket. It does this by showing a frame-by-frame replay of the footage of the ball passing the bat alongside a waveform displaying the soundwave of an oscilloscope connected to a sensitive microphone near the stumps.
The word “Snickometer” comes from the sound the ball makes when it hits the edge of the bat and the word “odometer,” which means “meter.”
To give you a quick idea of how it works:
1. Audio Sensors: The system grabs sounds from the game with sensitive microphones near the stumps and sometimes on the fielders.
The ball can make a unique sound if it hits the bat when it comes close to it (analysis of sound signals). The Snickometer looks at these sound messages and figures out what they mean.
2. Graphical Representation: After that, the system makes a picture often shown on TV screens during shows. There is a visual track of the audio signals over time in this image.
3. Time Match: The Snickometer is often time-matched with camera footage of the game. Anyone can watch the moment the ball hits the bat and hear any sounds that go with it.
4. Help With Making Decisions: The Snickometer doesn’t make decisions alone, but it helps match officials and watchers to decide if there is a nick. For example, Hot Spot uses infrared cameras to find the pressure and heat when the ball hits the bat.
Can Ultra Edge make wrong decisions?
This can also go wrong sometimes, just like any other device.
The first glitch might happen when the sound wave lengths increase before the ball hits the bat. This might happen because the mic picked up sounds from outside while the ball was thrown.
When the bat hits both the ground and the ball simultaneously, a second glitch can happen. In this case, the sound that the bat hears can be confusing. The third glitch can happen when the ball hits both the body and the bat at the same time. Sound lengths can become distorted because of this.
