Microphone array backscatter: an application-driven design for lightweight spatial sound recording over the air
Authors: Jia Zhao, Wei Gong, Jiangchuan Liu
Abstract
Modern acoustic wearables with microphone arrays are promising to offer rich experience (e.g., 360° sound and acoustic imaging) to consumers. Realtime multi-track audio streaming with precise synchronization however poses significant challenges to the existing wireless microphone array designs that depend on complex digital synchronization as well as bulky and power-hungry hardware.
