Bi-directional AI noise cancellation
Removes background noise coming from your microphone and from the other participants on the call, plus acoustic echo and room reverberation.
My Voice Only mode
Isolates your voice and heavily attenuates other speakers in the same room, which is handy in cafés, shared offices and open-plan spaces.
Screen and call recording with meeting minutes
Records screen and bi-directional audio, generates transcripts and automatic titles, then distils smart meeting minutes, keywords and sentiment.
Audio file enhancement
Cleans up existing mp3, wav and flac recordings — useful for podcasts, interviews and voice-overs that were captured in noisy environments.
Works as a virtual microphone in any conferencing app
Appears as a selectable input device in Zoom, Google Meet, Teams and browser apps, so no change of meeting workflow is required.
CrystalSound targets the everyday friction of online meetings: fans, traffic, cafés, shared offices, and the awkward echo that shows up when two people on the same call both use open speakers. Instead of asking you to change tools, it installs a virtual audio device that appears as an extra microphone in Zoom, Google Meet, Microsoft Teams, and browser-based conferencing. From there the app cleans the audio in real time, boosts mic level, and applies echo and room-reverberation suppression.
Beyond cleanup, CrystalSound acts as a lightweight meeting assistant. It records screen and bi-directional audio, produces transcripts and automatic titles, generates smart meeting minutes, and extracts keywords and sentiment so you can see which parts of a call mattered. "My Voice Only" mode isolates your own voice and pushes other speakers down, which is useful in crowded rooms, cafés, and open-plan offices. The product also includes audio-file enhancement for recorded media such as podcasts or interviews you already have on disk.
A notable design choice is privacy-oriented processing: the vendor advertises on-device AI for its noise-cancellation and screen-recording features, with cloud processing reserved for the higher transcription and analysis tiers. Audio-editing extras round out the app — pitch shift, reverb and a robotic voice effect — and audio files can be improved even if the original video is not a live meeting.
