Abstract: ABSTRACT: Title: A System and Method for Low-Latency Wireless Audio Transmission Using Smartphone-Based Software-Defined Microphone Architecture Over A Local Area Network The present invention relates to a low-latency wireless audio transmission system implemented using smartphone-based software-defined microphone architecture over a local area network. The system comprises a Host device configured to receive and output audio streams and one or more Joiner devices configured to capture and transmit audio data using a connectionless UDP communication pipeline. The system employs a two-layer architecture comprising a Flutter- based user interface layer and OS-specific native backend modules for audio capture, playback, buffer management, and network communication. Android devices use the AudioRecord and AudioTrack APIs, while iOS devices use the AVFoundation or Audio Unit RemoteIO interfaces. The system further incorporates Multicast DNS- based automatic peer discovery and adaptive jitter buffering for stable multi-stream playback. The invention enables scalable multi-user wireless microphone functionality with reduced end-to-end latency and supports integration with existing public address systems without requiring dedicated RF microphone hardware.
