No cuts. Switch at the same moment.
Synthetic demonstration: generated speech and background noise processed through Hush’s Strong filter. Not a recording of a real call. Results vary.
Transcript & how this was made
The demonstration transcript will appear here when the audio is ready.
The same noisy recording is used for both versions. The filtered version is produced by the actual Hush audio filter—not a separate clean take.
A familiar call.
A quieter microphone.
No new number.
No headset to buy.

Allow your microphone, check your sound, then make your call. Filtering starts on.
A few things
worth knowing.
Does it work with my headphones?
Use the headphones or microphone your browser supports. Setup includes a listening test, so you can check your own sound before a call. Different microphones and environments give different results.
Do I keep using WhatsApp?
Your account stays your account. Hush connects as a hosted WhatsApp linked device, and you make or answer filtered calls in Hush. It doesn’t filter ordinary cellular calls or every app on your phone.
Can I lock my phone during a call?
Not in this browser beta. Keep Hush open and your screen on during calls. Switching apps or locking your phone can interrupt audio. A native app is not available yet.
What happens to my data?
The hosted linked device can access your WhatsApp account data, so you need to trust the person operating Hush. Hush does not record your calls. You approve the connection during setup and can revoke it in WhatsApp → Linked devices.
Who can join?
This is an invitation-only beta for family and friends, with room for ten members and up to five simultaneous sound sessions. Access requests are reviewed by the organizer; requesting access doesn’t automatically create an account.
Will it fix a bad connection too?
This version reduces microphone background noise. Recovering damaged or missing speech is a separate research project, not a feature we’re claiming to deliver today.

Leave the noise.
