Abstract (English)

The CARROUSO project addresses the problem how to transfer sound fields, generated at a certain real or virtual space, to another usually remote located space. The system will have an enlarged listening area and will be more flexible in respect to the number and the configuration of loudspeakers. The activities concentrate on the development and implementation of key components for recording, transmission (including coding) and rendering. The transmission and coding will be based on MPEG and digital video broadcasting (DVB) technology.
Objectives:
The main objectives of the CARROUSO project are:1) to specify, develop, implement and validate a new technology that enables to transfer a sound field, generated at a certain real or virtual space, to another usually remote located space, this with full interactive control of its perceptually relevant natural temporal and spatial properties, especially in combination with the transmission of visual data. 2) to specify, develop, implement and validate new modelling, recording, encoding, decoding and rendering techniques for audio signals enabling the aforementioned technology.3) to build a real time demonstrator for the aforementioned technology.4) to define and monitor performance levels of the technology in perceptual experiments using the aforementioned demonstrator.
