ICASSP 2024: Robust DOA estimation from deep acoustic imaging

This board detects the direction of sound with 4-pdm mems mic using GCC-PHAT algorithm.

BSc Thesis: Design of Sound Source Localization System Based on FPGA and MEMS Microphone.

Pysoundlocalization aims to localize stationary and moving sound sources in polyphonic, noisy environments using sensors placed around the sound source(s). The library offers ready-for-use implementations to support sound source localization based on time difference of arrival (TDoA) and multilateration.

Official repository for the research paper "Sound Source Localization in a 3D Multi-Surface Environment Using Learning-Based Methods", performed in the Human & Robot Interaction Laboratory of the University of Tehran.

A local, fully offline sound-awareness assistant for hearing impairments. Uses on-device Sound Event Detection (SED), Direction-of-Arrival (DOA) estimation, and a local LLM to surface real-time radar alerts in a Tauri + React desktop UI.

Multi-track audio timebase estimation, alignment and clock-drift correction for recordings from independent devices. TimeMap abstraction, GCC-PHAT fine alignment, drift/changepoint estimation, multi-track graph solver, validation, Adobe Audition SESX export, and a dedicated MP4 wireless-microphone channel-sync pipeline.

iOS app that helps people with single-sided deafness localize sound using the iPhone's multi-microphone array. GCC-PHAT direction estimation, CROS passthrough, Apple Watch companion.
