Development of a software for panoramic video and audio recordings with microphone arrays

Abstract

Dense microphones array is certainly one of the most promising technology not only for environmental noise analysis, but also for 3D audio recordings, where 3D stands for a complete spatial description of the event recorded.

During last years at the Industrial Engineering Department of Università degli Studi di Parma (IED) with the collaboration of the spinoff AIDA srl., a new meta-theory was developed that provides a framework capable of representing all the known microphones array, based on the model of Virtual Microphones. The strict collaboration with the Centro Ricerca ed Innovazione Tecnologica (CRIT, Research Center and Technology Innovation) of RAI, the national Italian television broadcasting company, quickly individuates some key applications of this technology that conduct to the realization of some ad-hoc dense arrays and of a software to manage all the acquisition and post-processing system.

In this PhD thesis work a detailed description of the software, named 3D VMS, will be given, preceded by an introduction about the current state of the art of this technology.
