Huu? consists of two components: a directional microphone array and an AI denoising module. The mic array captures speech directionally and passes USB audio to the denoising module, which applies neural-network-based noise suppression in real time via NPU — delivering intelligible speech regardless of ambient noise levels.

 

The denoising module also accepts input from other existing USB microphones. In this configuration, directional capture is not available, but full noise suppression still applies — making Huu? compatible with microphone hardware already installed in kiosk or screen environments.

 

When used together with Supersensor, beam direction is updated automatically based on detected speaker position — no manual configuration required.

Core Capabilities:

  • Directional 4-microphone beamforming array
  • 30° – 360° beam coverage, 16 ms real-time steering
  • Acoustic Echo Cancellation (AEC)
  • Automatic Gain Control (AGC, 60 dB range)
  • Driverless USB audio output (class-compliant)
  • Compatible with any external USB microphone
  • AI noise suppression via NPU (RNNoise-based)
  • Effective capture range: 0.3 – 2 m
  • Voice Activity Detection (VAD)
  • Dereverberation processing
  • 3.5mm analog audio output
  • Remote configuration and firmware OTA via SignagePilot
