Discord used Krisp's audio-filtering technology for its noise-suppression feature added in 2020. Krisp is an audio-processing company whose machine-learning software separates speech from unwanted background sound in real time.
Discord integrated Krisp noise suppression into its desktop app in April 2020, during a period when remote work, online classes, and increased gaming made clear voice communication especially valuable. The feature could reduce sounds such as keyboards, household activity, traffic, and other voices before they reached other participants. It was later added to Discord's mobile app.
Krisp is sometimes confused with a microphone manufacturer, a traditional recording editor, or a general-purpose graphics company. It is a software and audio-processing business, not Audacity, Nvidia, or Dolby. Discord's feature also did not make every call perfectly silent: machine-learning suppression can affect voice quality and works best when distinguishing speech from relatively predictable background noise. Krisp was founded in 2017 by Davit Baghdasaryan and Artavazd Minasyan.
