The smartphones, as high computing multifunctional devices have become widespread by today. The so called "Android" open-source mobile operation system strongly supports the development of compatible applications with their freely available written materials.

In this thesis, the potential of acoustic localization on these devices is under consideration, which commonly requires specific devices. The aim is to develop a software, that can localize an audio source without using any other resource than the smartphones.

The structure of the Android compatible programs and the resources of a smartphone are discussed in particular, due to its high effects on the barriers and the accuracy of the earlier stated task.

The developed program is based on the so called Time Difference of Arrival (TDoA) method. The measurements of the needed data are carried out with the microphones of the devices.

At the end of the work, the obtained results of the developed software are examined and the weaknesses, along with the potential ways of improvements are discussed.
