There are some limitations using wifi, bluetooth or QR code when we communicate two devices on medical, rural or factories environment. In contrast, the communication via sound has interesting advantages over these technologies. In this paper we propose a comparative analysis of technologies for Audio Data Transmission (ADT). We analyze different ADT technologies that we selected validating some features such as the date of the last update or the support for Android operative systems. Subsequently, we tested two Android mobile applications using ADT technologies: Quiet and SinVoice. Also, we used two profiles for each technology: audible and inaudible. The applications send and receive a string as a byte array, and also they capture the delivery time in milliseconds. Then, we evaluated the results obtained through a comparative analysis in terms of distance, quantity of transmitted bytes and the time of sending and receiving of the information. The final results show the delivery time measurements of the technologies for each proposed scenario summarizing in tables and graphs.
