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，给大学的产学研带来了巨大的挑战。技术需求很多，可以在各种应用中找到：普通公众(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，实现高质量的收听体验所需要的主要工作是减少扬声器的干扰、串扰、非线性和其他失真在放大、传播和收听接收器(麦克风或听觉)中的影响。该项目汇集了三家公司，合作伙伴Simdio以及合作伙伴Arteluthe和Boreal Acoustics，他们都在共同开发技术诀窍和创新，以改善高性能音频系统的声音收听。该项目的主要目标是开发创新的方法，以改善工业合作伙伴的高性能音频系统中的收听和声音沉浸。这个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。根据魁北克-里维埃雷大学信号和系统集成S实验室及其合作伙伴多年来积累的专门知识，拟议的算法将提高听力质量，并将确保合作伙伴实现使其在竞争中脱颖而出的技术突破。这些结果将被合作公司用来完善他们的研发技术，并将其用于营销新产品。参与项目的学生将在项目开发的所有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.
