Description

From the listing uploaded by “appupdater”.

Ultrasonic communication (UC) is increasingly used for data exchange between mobile phones and other devices, as well as for location-based services. UC is attractive because it is inaudible and very low-threshold in terms of the hardware required (only microphone and speaker required). Today, there exist several proprietary solutions for UC on the market, which are developed by companies in a closed source form. SoniTalk is a novel open and transparent protocol for ultrasonic communication between devices such as smartphones, TVs, and IoT devices. Thereby SoniTalk gives the user full control over her privacy by a fine grained permission system. The SoniTalk Demo App demonstrates the use of the SoniTalk SDK for communication over sound. The default setting uses (near) ultrasonic frequencies.
