Acoustic testing and source mapping software

Classical algorithms of sound source localization with beamforming, TDOA and high-resolution spectral estimation.

Open-source acoustic drone detection. It hears the propellers, not the radio, so it works against fibre-optic FPV aircraft that emit no signal at all.

This is the public repository for eigenvector-based SALSA features for polyphonic sound event localization and detection.

some Matlab examples of microphone array beamforming

FP-AUD-SMARTMIC1 provides a firmware running on STM32 which acquires audio signals of four digital MEMS microphones, elaborates them by means of embedded DSP libraries and streams the processed audio to both an USB host and a loudspeaker. Please check st.com where a more recent version of the software might be available.

A list of toolboxes for acoustical beamforming.

This project uses Acoular to implement an acoustic camera for the miniDSP UMA-16 microphone array, with optional integration of a transformer model.

BSc Thesis: Acoustic source localization embedded system to estimate direction of sound arrival using time difference between sound wave arrival to 4 microphones.

ESP32-S3 four-microphone sound radar using I2S, TDOA, TFT direction display, and a web tuning dashboard.

This was a project that I did for my course. The project finds the direction of arrival and displays it using polar plots. If you have any queries, feel free to contact me. The codes were written using MATLAB 2017 and LabVIEW 2015
