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

音频技术引起了公众的极大兴趣，对工业和大学的研究提出了巨大的挑战。技术需求众多，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，实现高质量聆听体验所需的主要工作是减少放大、传播和聆听接收器（麦克风或听觉）中的干扰、串扰、扬声器的非线性和其他畸变的影响。该项目汇集了三家公司，合作伙伴Simaudio和合作者Arteluthe和Boreal Acoustics，共同开发技术和创新，以改善高性能音频系统的声音聆听。该项目的主要目标是开发创新方法，以改善工业合作伙伴高性能音频系统的听力和声音沉浸感。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来解决听众提出的复杂动态和非线性系统的主要挑战。根据法国三河流域大学的信号与系统<e:1>实验室多年来积累的专业知识及其合作，拟议的算法将提高倾听的质量，并确保合作伙伴取得技术突破，使其在竞争中脱颖而出。这些成果将被合作公司用来完善他们的研发技术，并推广新产品。参与项目的学生将在项目开发的各个阶段与合作伙伴进行讨论。

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.
