Sound Cleaner: Real-time noise suppression software

Overview

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
