:Analysis of the acoustic scene in multisource reverberant environments based on advanced sound field reconstruction techniquesAbstract:
This research arises from the recent developments in compact representation of the acoustic field. This convenient characterization and the acoustic transducers price drop enable the adoption of a large number of sensors for analyzing the acoustic scene.
As a consequence, new applications are rapidly emerging, stressing the need of facing different questions. In particular, the conflicting issues of spatial resolution and scene coverage arise in the analysis of acoustically complex environments. Hence, advanced signal processing techniques are needed to overcome this set of problems. Recently, the geometric parametrization of the plenacoustic information has emerged as a convenient tool for describing complex acoustic scenarios. This representation, combined with a priori knowledge about the environment allows the adoption of a super-resolution description of the acoustic scene.
It is foreseen the use of this representation to overcome the problems of working in highly challenging acoustic environments i.e. the analysis of the sound field.
Noteworthy, the possibility of working in acoustically complex environments allows us to describe real applicative scenarios to the benefit of a wide range of applications: e.g. the use of advanced sound field reconstruction techniques is desired in fields like virtual reality, studio recordings and environment monitoring.
Therefore, this approach will yield techniques that can be applied in different sectors, from multimedia to forensic analysis.
