T28 - Intelligent Acoustic Interfaces for High-Definition 3D Audio

Danilo Comminiello, Sapienza University of Rome - Rome, Italy

This tutorial aims at introducing a new paradigm for interpreting 3D audio in acoustic environments. Intelligent acoustic interfaces involve both sensors for data acquisition and signal processing methods with the aim of providing a high-quality 3D audio experience to a user. The tutorial explores the motivations for 3D intelligent interfaces. In that sense, the recent standardization of the MPEG-H has provided an incredible boost. Then, how to design 3D acoustic interfaces is analyzed, involving ambisonics and small arrays. Moreover, the main methodologies are introduced for the processing of recorded 3D audio signals in order to "provide intelligence" to interfaces. Here, we leverage the properties of signal processing in the quaternion domain. Finally, some examples of 3D audio applications are shown involving intelligent acoustic interfaces.
