Sound Share: P2P File-Sharing System

Abstract

Numerous types of connectivity are now necessary for hundreds of thousands of intelligent devices, including smartphones, tablets, industrial machinery, and home appliances. The inevitable demand for better connectivity in the IoT era has increased the expectations for even the most basic smart devices to have the capability to process real-time audio and perform intelligent digital signal processing (DSP) on the network's entry point device. This has ultimately paved the way for various innovative market entrants, looking to both challenges and work in tandem with traditional solutions to provide quality data-transmission capabilities. For engineers trying to enable frictionless interactions across an ever-increasing number of connected devices, one technology is now quickly emerging as an interesting connectivity opportunity. Anyone can utilize an ultrasonic beacon nowadays thanks to cell phones with high-frequency-capable speakers and microphones. Data-over-sound allows for the transmission of data by sound waves between any devices which already have a loudspeaker or microphone, which makes it easier for anyone with basic knowledge of how to use a smartphone will be able to communicate with ease. The proposed system will have 2 peers, a receiver, and a sender, whereby converting the session data into audio tones, transmits an offer for a WebRTC connection to the other peer. who wants to connect respond with an audio answer, and the transmitted audio answer is captured by the peer who broadcasted an offer for WebRTC connection, and it is decoded and allows the other peer to connect, and then the connection is established.
