Acoustic detection prototype using GCC-Phat on microcontroller

Abstract

This paper presents an acoustic directional detect device’s development and design based on the Generalized Cross-Correlation PHAseTransform (GCC-PHAT) technique. The topic’s primary goal is to build a KIT that supports audio Processing, including a 4- channel Microphone array and a popular microcontroller, STM32FI03c8t6, embedded with GCC-PHAT algorithm to estimate the direction and intensity of the sound source captured. We also have tested, evaluated, and compared the performance with a sound source localization device on the market. The article focuses on data Processing and optimizing computational methods to enhance performance while overcoming the limitation of the microcontroller.
