The aim of this bachelor's thesis is to design and develop an Android application for musicians. The theoretical part, is conceived as an introduction to the theory of sound. Firstly, I describe the architecture of Android and the individual components that make it up. There are subsequent chapters exploring the sound from its inception, through the process of converting to digital form, to a description of the individual interfaces for the recording and processing from within the environment of an Android system. The practical part, is devoted to designing and developing an application that serves as a tool for practicing playing a musical instrument. The application consists of various features such as: tuner, metronome and an EarTrainer. To understand the component of a tuner it has been necessary to study a theory needed to support the main functionality of calculating the frequency of the recorded audio signal. For this reason, this thesis is also a theoretical introduction to the Fourier transformation. The last part of this thesis is focusing on how the tuner compares with the calculation accuracy of other competitors. Finally, The application was published for the Google Play store.
