A Generalized Bandsplit Neural Network for Cinematic Audio Source Separation

1 code implementation5 Sep 2023 Karn N. Watcharasupat, Chih-Wei Wu, Yiwei Ding, Iroro Orife, Aaron J. Hipple, Phillip A. Williams, Scott Kramer, Alexander Lerch, William Wolcott

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.

Assessment of a cost-effective headphone calibration procedure for soundscape evaluations

1 code implementation24 Jul 2022 Bhan Lam, Kenneth Ooi, Zhen-Ting Ong, Karn N. Watcharasupat, Trevor Wong, Woon-Seng Gan

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 global ``Soundscape Attributes Translation Project'' (SATP) for validating ISO/TS~12913-2:2018 perceived affective quality (PAQ) attribute translations.

Do uHear? Validation of uHear App for Preliminary Screening of Hearing Ability in Soundscape Studies

1 code implementation16 Jul 2022 Zhen-Ting Ong, Bhan Lam, Kenneth Ooi, Karn N. Watcharasupat, Trevor Wong, Woon-Seng Gan

Hence, in this study, we investigate the effectiveness of the uHear app, an iOS application, as an affordable and automatic alternative to a conventional audiometer in screening participants for hearing loss for the purpose of soundscape studies or listening tests in general.

Preliminary assessment of a cost-effective headphone calibration procedure for soundscape evaluations

no code implementations10 May 2022 Bhan Lam, Kenneth Ooi, Karn N. Watcharasupat, Zhen-Ting Ong, Yun-Ting Lau, Trevor Wong, Woon-Seng Gan

Preliminary experiments found that calibration with the OCV method differed significantly from the reference binaural recordings in sound pressure levels, whereas negligible differences in levels were observed with the HATS calibration.

Autonomous In-Situ Soundscape Augmentation via Joint Selection of Masker and Gain

no code implementations29 Apr 2022 Karn N. Watcharasupat, Kenneth Ooi, Bhan Lam, Trevor Wong, Zhen-Ting Ong, Woon-Seng Gan

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 environment.

Deployment of an IoT System for Adaptive In-Situ Soundscape Augmentation

no code implementations29 Apr 2022 Trevor Wong, Karn N. Watcharasupat, Bhan Lam, Kenneth Ooi, Zhen-Ting Ong, Furi Andi Karnapi, Woon-Seng Gan

Soundscape augmentation is an emerging approach for noise mitigation by introducing additional sounds known as "maskers" to increase acoustic comfort.

Improving Polyphonic Sound Event Detection on Multichannel Recordings with the Sørensen-Dice Coefficient Loss and Transfer Learning

no code implementations22 Jul 2021 Karn N. Watcharasupat, Thi Ngoc Tho Nguyen, Ngoc Khanh Nguyen, Zhen Jian Lee, Douglas L. Jones, Woon Seng Gan

The S{\o}rensen--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 significantly exceeds that of positive samples, such as semantic segmentation, natural language processing, and sound event detection.
