The goal of the work is to improve the accuracy and reliability of detecting and recognizing sound sources in the controlled locality by developing new methods for processing audio signals, circuits, algorithms, hardware and software tools for analog-digital (AD) audio location and identification systems. Research methods are modeling of parallel digital scanning processes, search and identification of sound objects using neuro fuzzy technologies and noise-resistant coding, modeling, prototyping and experimental research of receiving, amplifying, AD-conversion devices, adjusting measuring channels. The general structure of the AD-system audio location and identification of objects on the locality has been developed and technical requirements for development directions have been formulated. The analysis of structural, circuit design and algorithmic solutions in the technique of amplification, AC-conversion and signal processing of microphone arrays are performed. Static and dynamic characteristics of measuring channels of AD systems, their influence on the accuracy of the location of sound objects and on the quality of sound fragments are analyzed, new methods for their calibration are proposed and investigated. Low noise high linear current signal amplifiers are investigated. The structures of parallel signal processing with multi-channel scanning, the algorithm and the program of forming directivity diagrams have been developed. A model was designed and manufactured and purchases of electronic and computer components for an experimental sample of the AD-system were made.
