This paper presents an acoustic directional detect device’s development and design based on the Generalized Cross-Correlation PHAseTransform (GCCPHAT) 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, STM32F103c8t6, embedded with GCC-PHAT algorithm to estimate the direction and intensity of the sound source captured. |
