AI noise cancellation app for virtual meetings, with screen recording and AI-generated meeting minutes.

CrystalSound is an on-device AI audio tool designed to improve virtual meeting quality. Its core feature is bi-directional noise cancellation — removing background noise from both the user's microphone and the incoming audio of other participants. It integrates as a virtual microphone in any conference app (Zoom, Google Meet, etc.) and additionally offers screen and audio recording, automatic meeting minutes generation, keyword and sentiment analysis, and a voice changer. The on-device processing model means audio is not sent to the cloud in the Enterprise plan. Available on Windows, macOS, and Linux. Pricing has a free starter tier and a 7-day free trial for Premium.
