Portable Acoustic Imaging Array

Portable Acoustic Imaging Array

Overview

The ASAI144 Portable Acoustic Imaging Array is an FPGA-based acoustic front-end module designed for real-time sound visualization and localization.
Equipped with 144 high-performance MEMS microphones, it utilizes advanced beamforming algorithms to transform acoustic signals into dynamic “sound videos,” synchronizing sound and image in real time.

Thanks to the highly optimized acoustic algorithms and FPGA’s parallel computing power, the ASAI144 achieves true high-frame-rate real-time acoustic imaging — ideal for detecting and locating transient noise sources in industrial, R&D, or embedded applications.
