Denoiser Box: Real-time noise filtering

Overview

Denoiser Box is an ultra-compact device based on STC award-winning Denoiser DSP board and designed for real-time enhancement of analog audio signal. Denoiser Box decreases overall noise level greatly improving speech signal intelligibility.

Applications

• Police, Technical investigators, Surveillance team, Private investigators, Forensic labs and other Law Enforcement Agencies: live sound and speech quality improvement while recording or listening in field conditions.
• Broadcasting companies: mastering of “live” interviews and reports.
• To reach the most efficiency results it is strongly recommended to filter a signal via Denoiser Box before recording and processing.

Features

• Effectively decreases broadband (industrial, street, etc.) and harmonic noises and interferences. Adaptive noise filtering algorithms keep speech signal clear and undistorted
• Removes noises from:
  • air conditioning
  • PC and office equipment
  • vacuum cleaners
  • radio channel
• Signal bandwidth adjustable
• Adjustable AGC (automatic gain control)
