Discord launches noise suppression for its mobile app

Voice, video, and text communication service Discord is launching noise suppression for mobile audio calls. That means no one will notice if you’re taking a walk in a windy park during a meeting — or making noises in the toilet.

Based on the publicly available Krisp machine-learning-based audio filtering technology, Discord’s app will now filter out noise. The machine learning algorithm looks for sounds that are common background noises in calls and then stops them from being passed on to the audio compression technology, which in turned is based on the Opus audio codec. Discord’s platform depends on both Krisp and Opus to provide high-quality audio for more than 100 million monthly active users, who also use the platform’s video and text chat features.
