STC-H246
To guarantee the high quality of input and output signal processing, IKAR Lab 3 suite comes equipped with a professional audio device.
Designed to measure parameters and generate electrical signals in the audio frequency range, it is a perfect device when setting up a workstation for digitizing analog audio recordings and forensic examination of audio data
how it works
how IKAR Lab 3 transforms raw audio into evidence
icon_how_it_works1
intelligibility boost
smart algorithms reduce noise and increase the intelligibility of target speech for further analysis
icon_how_it_works2
authenticity check
recordings are investigated to determine if the data had been falsified, tampered with or synthesized
icon_how_it_works3
content extraction
speech recognition converts voice data into text, even from coded and slang-heavy conversations
icon_how_it_works4
speaker identification
speakers are identified by comparing the voiceprint model with an existing sample, independent of the language
