Fine‐scale observations of spatio‐spectro‐temporal dynamics of bird vocalizations using robot audition techniques

open access: yesRemote Sensing in Ecology and Conservation, 2021
Ecoacoustics needs sophisticated acoustic monitoring tools to extract a wide level of features from an observed mixture of sounds. We have developed a portable acoustic monitoring system called ‘HARKBird’ which consists of a laptop PC and an inexpensive ...

Design exploration and performance strategies towards power-efficient FPGA-based achitectures for sound source localization [PDF]

open access: yes, 2019
Many applications rely on MEMS microphone arrays for locating sound sources prior to their execution. Those applications not only are executed under real-time constraints but also are often embedded on low-power devices.

NMF-weighted SRP for multi-speaker direction of arrival estimation: robustness to spatial aliasing while exploiting sparsity in the atom-time domain

open access: yesEURASIP Journal on Audio, Speech, and Music Processing, 2021
Localization of multiple speakers using microphone arrays remains a challenging problem, especially in the presence of noise and reverberation. State-of-the-art localization algorithms generally exploit the sparsity of speech in some representation for ...

Spheroidal ambisonics: Spatial audio in spheroidal bases [PDF]

open access: yesJASA Express Letters, 2021
Ambisonics is an established framework to capture and reproduce spatial sound fields based on the spherical harmonics representation [Gerzon (1973). J. Audio Eng. Soc. 21(1), 2–10].
