upHear Microphone Processing

Unleash the True Potential of any Microphone

When integrated into a device, upHear Microphone Processing guarantees an exceptional audio experience that will keep users connected and engaged. Designed to seamlessly adapt to varying acoustic conditions, however challenging they may be, our technology gives users the choice of what they want to hear and what they don’t.
upHear Microphone Processing offers a variety of technologies covering a broad range of use cases – from removing background noise to extracting a specific voice or capturing immersive audio.

(Multichannel) Echo Control

For easy barge-in and high-quality communication via smart speakers.


Improved intelligibility and SNR of far-field voice pickup.

Noise Reduction

Focus on the voice without being distracted by background sounds and noise.


Improved intelligibility and comfort in reverberant rooms.

Automatic Gain Control

Capture the user's speech from any distance with constant loudness.

Spatial Upmix

Increases the spatial resolution of the recorded immersive sound.

Wind Noise Reduction

Perceiving optimum speech quality even in windy outdoor environments.

Audio Zoom

Realtime focus on specific sources or genera-tion of immersive spatial sound.

AI-based Noise Reduction

Advanced noise reduction capabilities meet low-complexity AI: upHear AI-Based Noise Reduction enables high-class performance while keeping a low complexity and energy footprint, which results in low battery consumption. Its compatibility with standard CPUs and DSPs omits any need for specialized costly GPUs or NPUs. The technology is deployable on edge devices or even in cloud services.
Despite its low demands on the hardware side, upHear AI-Based Noise Reduction delivers astonishing functionality: its adjustable intensity puts it into the hands of the user, how much of the background noise they want removed, giving them the ability to find the optimal balance between voice signals and ambience. The low processing delay enables interruption-free natural conversation. upHear AI-based Noise Reduction can be used at the sending as well as the receiving end. The technology is available as a standalone module and therefore can easily be used with any acoustic front end.

Typical Application Scenarios
