Denoiser Box is a compact device designed for real-time enhancement of analog audio signals. It decreases overall noise level, greatly improving speech signal intelligibility.

Denoiser Box is most effective when included in audio recording or transmission channel before the analog signal is converted to digital; e.g. between a microphone and voice-recorder or telephone.

Applications

Police, Technical investigators, Surveillance teams, Private investigators, Forensic labs and other Law Enforcement Agencies: Live sound and speech quality improvement while recording or listening in field conditions.

Highlights
  • Extremely easy to use, all the adjustments are made with a single knob
  • Effectively decreases broadband (industrial, street etc.) harmonic noises and interferences. Adaptive noise filtering algorithms keep speech signal clear and undistorted
  • All kinds of noises and interferences are suppressed due to adaptive stereo filtering algorithms using reference channel
  • Signal bandwidth adjustment
  • Adjustable AGC (Automatic gain control)
  • STC experts provide basic and advanced training in speech enhancement

Specifications

  • Noise suppression depth:
    • 0-24 dB for single-channel filtering
    • 0-40 dB for reference channel stereo filtering
  • Operating time (without battery change) - up to 4 hours.
  • Signal sampling rate:
    • 11 025 Hz for single-channel scheme
    • 8 000 Hz for dual-channel scheme
  • Adjustable signal bandwidth - 200-5000 or 300-3400 Hz.
  • AGC adjustment range:
    • 12 dB input
    • 6 dB output
  • Size: 110x45x113 mm.
