Riot Games has revealed the technology it used to help deliver clear communication between professional League of Legends players who are competing in a tournament in front of a live audience. The developer took action following an issue concerning noise from the audience at the NA LCS Spring finals at Vegas, who was so loud it created audio issues for players.

In an interview with Yahoo Esports, Riot Games live producer Nick Troop described how they utilized the technology to solve the issue of audience noise interrupting player communication.

Powered by a third-party entity commonly used in broadcast environments for sports like football, hockey, baseball or basketball, the technology uses machine learning to listen to the environment and distinguish between good or bad audio, cutting out the noise from the audience so that players are able to hear one another clearly.

“It’s a vendor that we found from the broadcasting world, and we are utilizing their equipment,” Troop explained in the interview. “We introduced this in the semi-finals in studio… and right away we heard TSM chants from the show. I was eavesdropping from the back to understand what the equipment was doing and it basically went ‘T’, and then the ‘S’ was quieter, and then the ‘M’ didn’t exist because the chant was basically invisible on the headset from there.”

Troop also addressed the open-air booths that the players were seated in during Worlds, referring to them as “competitive integrity shields.” The curved shield-like structures contain three inches of professional-grade sound insulation covered with multi-textured foam, which helps to absorb and break up external noise.

In recent League of Legends news, Riot Games has released an infographic providing an overview of the viewership for this year’s League of Legends World Championship. The company has also just released the final balance changes for patch 6.24, which introduces a number of gameplay tweaks and new champion Camille.
