SOUND CLEANER 

Award of International forum “Security and Safety Technologies”

The first prize in audio enhancement contest
organized by AES (Audio Engineering Society)

Application

Police, Forensic labs and other Law Enforcement Agencies; Audio Engineers and Audio Restoration:

• Noise suppression and speech enhancement in low quality recordings
• Text decoding (transcription) of noisy recordings
• Audio pre-processing for identification
• Noise suppression while getting field data

Features

• Sound input from line output and microphones or from sound files and processing
• Saving results in *.wav format
• Real-time noise suppression, changing filtering settings without playback stop
• Automatic report on sound processing for expert’s conclusion
• Preset filtering schemes for typical noises
• Saving filters parameters for further usage
• DirectX support

Highlights

• Efficient suppression of all types of noises and distortions
• Adaptive algorithms of filtering
• Easy to use
• Filers can be combined to process the noisy record simultaneously
• Low quality records processing for further instrumental ID analysis: “weak” formants enhancement

Technical characteristics

Sound Cleaner can be supplied as a separate product or as a part of IKAR-Lab.

• Sound Cleaner contains 19 different modules of speech processing and enhancement:
  • 2 adaptive filters of broadband noises
  • Parametric equalizer
  • Harmonic filter
  • Adaptive inverse filter
  • Amplifier
  • Adaptive filter for tonal noises
  • Impulse noises filter
  • Dynamic filter (weak signal amplifying/weakening, strong signal weakening)
  • Anti-reverberation filter
  • Stereo signal filtering by reference channel
  • Others
• Practical recommendations for noise suppression and text decoding.
