Class-Incremental Learning for Sound Event Localization and Detection
Ruchi Pandey, Manjunath Mulimani, Archontis Politis +1
This paper investigates the feasibility of class-incremental learning (CIL) for Sound Event Localization and Detection (SELD) tasks. The method features an incremental learner that…
SynthSOD: Developing an Heterogeneous Dataset for Orchestra Music Source Separation
Jaime Garcia-Martinez, David Diaz-Guerra, Archontis Politis +3
Recent advancements in music source separation have significantly progressed, particularly in isolating vocals, drums, and bass elements from mixed tracks. These developments owe m…
Gaunt coefficients for complex and real spherical harmonics with applications to spherical array processing and Ambisonics
Archontis Politis
Acoustical signal processing of directional representations of sound fields, including source, receiver, and scatterer transfer functions, are often expressed and modeled in the sp…
Reference Channel Selection by Multi-Channel Masking for End-to-End Multi-Channel Speech Enhancement
Wang Dai, Xiaofei Li, Archontis Politis +1
In end-to-end multi-channel speech enhancement, the traditional approach of designating one microphone signal as the reference for processing may not always yield optimal results.…
Speaker Distance Estimation in Enclosures from Single-Channel Audio
Michael Neri, Archontis Politis, Daniel Krause +2
Distance estimation from audio plays a crucial role in various applications, such as acoustic scene analysis, sound source localization, and room modeling. Most studies predominant…
Sound Event Detection and Localization with Distance Estimation
Daniel Aleksander Krause, Archontis Politis, Annamaria Mesaros
Sound Event Detection and Localization (SELD) is a combined task of identifying sound events and their corresponding direction-of-arrival (DOA). While this task has numerous applic…
Perceptually-motivated Spatial Audio Codec for Higher-Order Ambisonics Compression
Christoph Hold, Leo McCormack, Archontis Politis +1
Scene-based spatial audio formats, such as Ambisonics, are playback system agnostic and may therefore be favoured for delivering immersive audio experiences to a wide range of (pot…
Neural Ambisonics encoding for compact irregular microphone arrays
Mikko Heikkinen, Archontis Politis, Tuomas Virtanen
Ambisonics encoding of microphone array signals can enable various spatial audio applications, such as virtual reality or telepresence, but it is typically designed for uniformly-s…
