3D Audiosense

A System for Virtual Sound Stage Reconstruction Using Wireless Sensor Networks 

Main goal:
The project's main objective was to create a prototype system that would capture spatial audio scenes using a distributed wireless sensor network. ​


Features:

• Sound recording is performed in real-time by microphones embedded in each sensor node. 
• Audio processing and coding will be performed externally or inside the wireless sensor network.
• This process is optimized considering signal correlation and all the hardware limitations of the constrained sensor nodes. 
• The system will be highly mobile and easily deployable as all the sensors will be battery-operated and can self-organize using their wireless interfaces. 

Use case scenarios:

• AudioSense can significantly improve the listening experience through high-density 3D audio coding and spatial sound scene reconstruction. 
• Additionally, AudioSense can support flexible manipulation of sound scenes at the receiver side, allowing for its rendering with a traditional set of surround sound loudspeakers and an advanced higher-order ambisonic or a wavefield synthesis system. Therefore, the user will be immersed in his favorite music performance, documentary, sport event, and live TV broadcast.
