HOW IT WORKS

From microphone to chat in four steps.

Choose the microphone

Select the headset or microphone you want to use as the physical input.

Shape the voice

Voice Studio, AI Noise Suppression, echo and additional filters process the voice locally.

Mix the music

Start the playlist and control the music/microphone balance with volume controls and the crossfader.

Output virtually

The finished mix is delivered to the chat or voice application as a virtual microphone.

Local voice processing with control over the signal path.

RNNoise voice cleanup runs locally on the Windows PC. Your microphone audio does not need to be sent to an external AI service for neural noise suppression.

Local RNNoise

Neural noise suppression runs directly on the device.

Virtual routing

You choose the physical microphone and virtual output used by the application.

Headphone monitoring

Listen to the final mix locally before and during use.

Device-based license

The device identifier is SHA-256-derived instead of transmitting the plain MachineGuid.
