Méthodes d'amélioration de l'écoute sonore dans les systèmes audio haute performance

音频技术吸引了公众的极大兴趣，并对工业和大学的研究提出了巨大的挑战。技术需求很多，可以在各种应用中找到：一般公众（家庭影院系统、便携式多媒体播放器）、汽车和医疗部门（例如助听器）。从数字信号处理的角度来看，实现高质量听音体验所需的主要工作是减少扬声器的干扰、串扰、非线性以及放大、传播和听音接收器（麦克风或听觉）中的其他失真的影响。该项目汇集了三家公司，合作伙伴Simaudio和合作伙伴Arteluthe和Boreal Acoustics，共同开发提高高性能音频系统声音聆听的专有技术和创新。该项目的主要目标是开发创新方法，以改善工业合作伙伴的高性能音频系统的聆听和声音沉浸感。该项目提出了几个原创和创新的方面，包括动态和非线性方法，以解决听众提出的复杂动态和非线性系统的主要挑战。基于魁北克三河大学信号与系统集成实验室多年积累的专业知识及其合作，拟议的算法将提高听力质量，并确保合作伙伴实现技术突破，使其在竞争中脱颖而出。合作伙伴公司将利用这些成果来完善其研发知识和营销新产品。参与该项目的学生将在项目开发的各个阶段参与与合作伙伴的讨论。

Audio technologies attract much interest from the general public and represent great challenges for industry and research in universities. Technological needs are numerous and can be found in various applications: the general public (home theatre systems, portable multimedia players), the automobile and the medical sector (e.g. hearing aids). From the point of view of digital signal processing, the main work required to achieve the high quality listening experience is to reduce the effect of interference, crosstalk, non-linearity of the loudspeakers and other distortions in the amplification, propagation and listening receiver (microphone or auditory). The project brings together three companies, partner Simaudio and collaborators Arteluthe and Boreal Acoustics, all working together to develop know-how and innovations for improving sound listening in high-performance audio systems. The main objective of this project is the development of innovative methods for improving listening and sound immersion in the high-performance audio systems of industrial partners. This project presents several original and innovative aspects, including dynamic and non-linear methods to address the major challenges of complex dynamic and non-linear systems presented by the listener. Based on the know-how accumulated for many years at the Laboratoire de signaux et systèmes intégrés of the Université du Québec à Trois-Rivières and its collaborations, the proposed algorithms will increase the quality of listening and will ensure that partners achieve technological breakthroughs that distinguish them from the competition. The results will be used by partner companies to refine their R & D know-how and to market new products. Students involved in the project will participate in discussions with partners at all stages of the project development.
