ZoomVoice software enables emphasizing a voice from target direction and suppressing ambient noises. This software is suitable for accuracy improvement of speech recognition devices and voice recording/communication devices.

  • Beamforming: Reduces noise from other directions (using two microphones)
  • Noise Suppressor: Reduces stationary noise

Product Overview

Features

  • It can be realized with two inexpensive omnidirectional microphones.
  • Original beam forming (directivity formation) and noise suppressor (steady noise reduction) to reduce noise.
  • The maximum amount of noise reduction is 30 dB (approx. 1/30).

Specifications

  • Sampling frequency 16kHz
  • Input data format 16-bit linear PCM (2 channels)
  • Output data format 16-bit linear PCM (1 channel)
  • Strength of beam forming reduction 7 levels of adjustment possible
  • Reduction strength of noise suppressor 7 levels of adjustment possible

Supported MCUs

RZ/G1H, RZ/G1M, RZ/G1N, RZ/G1E, RZ/G1C
