The majority of existing applications that enable audio communication does not work without an internet connection. This led us to explore the possibilities for implementing an application that would enable users to use audio communication over Wi-Fi Direct protocol. The application, intended for devices with Android operational system, will enable real-time transfers of audio messages. The first step in addressing the problem was to implement an application that enables sending audio by saving to a file. After a successful development, the application was upgraded and developed into the end product. Later, we used both versions of the application to compare the delays.
