Abstract
This paper presents an Android application for real-time audio communications over local wireless (Wi-Fi) networks. The system implements low-latency voice communication between Android devices over a local Wi-Fi network, covering audio capture, encoding, transmission via UDP/RTP, and playback. Performance measurements demonstrate the viability of real-time audio communications using commodity Android devices without external infrastructure.
