Abstract

This paper presents the development of a prototype system, which would be able to capture spatial audio scene using a wireless acoustic sensor network (WASN). Sound recording is performed in real-time by microphones embedded in each sensor node. Proposed approach is focused on processing of spatial audio objects instead of multichannel audio representation. It gives the flexibility of sound processing, mastering, and reproduction on different sound systems. This paper discusses key aspects and technologies used to build a prototype system, which are related to time synchronization of captured sounds, wireless protocols, sound source separation, and 3-D audio compression.
