Résumé

Real-time auralization systems have been developed for room acoustic simulations. For high quality spatial rendering, many of these systems have used binaurual rendering. This paper presents the implementation of a real-time room acoustics auralization system using an array of 157 loudspeakers. The room acoustic model uses a combination of an iterative image-source model and feedback delay networks to create the reflections and reverberation. Higher-order Ambisonics (HOA) is used to generate spatial room impulse responses. The speaker array uses a density grid of 50 cm and covers the walls and ceiling of a treated listening room. A distributed network system has been used to create the auralization. All software components of this system are Open-Source. In this paper, we introduce this system and discuss about the synchronous estumation of 157 audio signals.
