3D Room Geometry Inference from Multichannel Room Impulse Response using Deep Neural Network

no code implementations19 Jan 2024 Inmo Yeon, Jung-Woo Choi

Room geometry inference (RGI) aims at estimating room shapes from measured room impulse responses (RIRs) and has received lots of attention for its importance in environment-aware audio rendering and virtual acoustic representation of a real venue.

Noisy-ArcMix: Additive Noisy Angular Margin Loss Combined With Mixup Anomalous Sound Detection

no code implementations10 Oct 2023 Soonhyeon Choi, Jung-Woo Choi

Unsupervised anomalous sound detection (ASD) aims to identify anomalous sounds by learning the features of normal operational sounds and sensing their deviations.

RGI-Net: 3D Room Geometry Inference from Room Impulse Responses in the Absence of First-order Echoes

no code implementations4 Sep 2023 Inmo Yeon, Jung-Woo Choi

However, the conventional RGI technique poses several assumptions, such as convex room shapes, the number of walls known in priori, and the visibility of first-order reflections.

DeFTAN-II: Efficient Multichannel Speech Enhancement with Subgroup Processing

no code implementations30 Aug 2023 Dongheon Lee, Jung-Woo Choi

In the proposed split dense blocks extracting spatial features, a pair of subgroups is sequentially concatenated and processed by convolution layers to effectively reduce the computational complexity and memory usage.

Divided spectro-temporal attention for sound event localization and detection in real scenes for DCASE2023 challenge

no code implementations5 Jun 2023 Yusun Shul, Byeong-Yun Ko, Jung-Woo Choi

Localizing sounds and detecting events in different room environments is a difficult task, mainly due to the wide range of reflections and reverberations.

Inter-channel Conv-TasNet for multichannel speech enhancement

no code implementations8 Nov 2021 Dongheon Lee, Seongrae Kim, Jung-Woo Choi

In this study, we propose an end-to-end time-domain speech enhancement network that can facilitate the use of inter-channel relationships at individual layers of a DNN.
