On-line sound event localization and detection for real-time recognition of surrounding environment

Kento Nagatomo et al.

Summary: This paper discusses the online execution of sound event localization and detection (SELD) tasks. Experimental results show the relationship between the latency of an online SELD system and its localization accuracy, while event detection performance decreases in low latency.

SALSA: Spatial Cue-Augmented Log-Spectrogram Features for Polyphonic Sound Event Localization and Detection

Thi Ngoc Tho Nguyen et al.

Summary: The SALSA feature is a novel feature that accurately maps the relationship between signal power and source directional cues in time-frequency domain, effectively solving the issue of overlapping sound sources. Experimental results demonstrate that SALSA features outperform other state-of-the-art features, significantly improving the accuracy of sound event detection and direction-of-arrival estimation when used in FOA and MIC formats.

Sound source localization method by using a single moving microphone and inner product calculation

Xiaodan Zhao et al.

Summary: This paper proposes a simple and cost-effective method for sound source localization by collecting sound pressure signals while a microphone moves at low speed and conducting mathematical research to locate the source, which can effectively eliminate interference and improve localization accuracy.
