Outstanding Audio


This utility leverages a massive deep-learning database to reduce background noise from the microphone and incoming audio, while preserving vocals at the same time. This removes distracting keyboard clatter, mouse clicks and other ambient noises so you can hear and be heard with crystal clarity while gaming or in calls.

*An audio splitter (3.5 mm audio jack Y-cable) is necessary when using a 3.5 mm headset.
