| Abstract: | Microphone sound source localization is a kind of sound source localization technology, picking up sound signal by microphone array, analyzing and processing by digital signal processing. A sound source localization system based on MUSIC algorithm was designed, taking DSP as the controlling core. The processing speed of the system was improved through TMS320C6747 high speed digital signal processor. The design was simplified to better meet the requirements of sound source localization. Test result showed the system had the advantages of real time, high speed, high precision and good reliability. |
