A Generalized Bandsplit Neural Network for Cinematic Audio Source Separation
Karn N. Watcharasupat, Chih-Wei Wu, Yiwei Ding +6
Cinematic audio source separation is a relatively new subtask of audio source separation, with the aim of extracting the dialogue, music, and effects stems from their mixture. In t…
Preliminary investigation of the short-term in situ performance of an automatic masker selection system
Bhan Lam, Zhen-Ting Ong, Kenneth Ooi +4
Soundscape augmentation or "masking" introduces wanted sounds into the acoustic environment to improve acoustic comfort. Usually, the masker selection and playback strategies are e…
Quantifying Spatial Audio Quality Impairment
Karn N. Watcharasupat, Alexander Lerch
Spatial audio quality is a highly multifaceted concept, with many interactions between environmental, geometrical, anatomical, psychological, and contextual considerations. Methods…
Assessment of a cost-effective headphone calibration procedure for soundscape evaluations
Bhan Lam, Kenneth Ooi, Zhen-Ting Ong +3
To increase the availability and adoption of the soundscape standard, a low-cost calibration procedure for reproduction of audio stimuli over headphones was proposed as part of the…
Do uHear? Validation of uHear App for Preliminary Screening of Hearing Ability in Soundscape Studies
Zhen-Ting Ong, Bhan Lam, Kenneth Ooi +3
Studies involving soundscape perception often exclude participants with hearing loss to prevent impaired perception from affecting experimental results. Participants are typically…
Preliminary assessment of a cost-effective headphone calibration procedure for soundscape evaluations
Bhan Lam, Kenneth Ooi, Karn N. Watcharasupat +4
The introduction of ISO 12913-2:2018 has provided a framework for standardized data collection and reporting procedures for soundscape practitioners. A strong emphasis was placed o…
Deployment of an IoT System for Adaptive In-Situ Soundscape Augmentation
Trevor Wong, Karn N. Watcharasupat, Bhan Lam +4
Soundscape augmentation is an emerging approach for noise mitigation by introducing additional sounds known as "maskers" to increase acoustic comfort. Traditionally, the choice of…
Autonomous In-Situ Soundscape Augmentation via Joint Selection of Masker and Gain
Karn N. Watcharasupat, Kenneth Ooi, Bhan Lam +3
The selection of maskers and playback gain levels in a soundscape augmentation system is crucial to its effectiveness in improving the overall acoustic comfort of a given environme…
AVASpeech-SMAD: A Strongly Labelled Speech and Music Activity Detection Dataset with Label Co-Occurrence
Yun-Ning Hung, Karn N. Watcharasupat, Chih-Wei Wu +4
We propose a dataset, AVASpeech-SMAD, to assist speech and music activity detection research. With frame-level music labels, the proposed dataset extends the existing AVASpeech dat…
SALSA-Lite: A Fast and Effective Feature for Polyphonic Sound Event Localization and Detection with Microphone Arrays
Thi Ngoc Tho Nguyen, Douglas L. Jones, Karn N. Watcharasupat +2
Polyphonic sound event localization and detection (SELD) has many practical applications in acoustic sensing and monitoring. However, the development of real-time SELD has been lim…
End-to-End Complex-Valued Multidilated Convolutional Neural Network for Joint Acoustic Echo Cancellation and Noise Suppression
Karn N. Watcharasupat, Thi Ngoc Tho Nguyen, Woon-Seng Gan +2
Echo and noise suppression is an integral part of a full-duplex communication system. Many recent acoustic echo cancellation (AEC) systems rely on a separate adaptive filtering mod…
SALSA: Spatial Cue-Augmented Log-Spectrogram Features for Polyphonic Sound Event Localization and Detection
Thi Ngoc Tho Nguyen, Karn N. Watcharasupat, Ngoc Khanh Nguyen +2
Sound event localization and detection (SELD) consists of two subtasks, which are sound event detection and direction-of-arrival estimation. While sound event detection mainly reli…
Improving Polyphonic Sound Event Detection on Multichannel Recordings with the Sørensen-Dice Coefficient Loss and Transfer Learning
Karn N. Watcharasupat, Thi Ngoc Tho Nguyen, Ngoc Khanh Nguyen +3
The Sørensen--Dice Coefficient has recently seen rising popularity as a loss function (also known as Dice loss) due to its robustness in tasks where the number of negative samples…
