Implementation of digital metronome with oversampling in VST technology
Křupka, Aleš ; Přikryl, Lubor (referee) ; Mačák, Jaromír (advisor)
This bachelor’s thesis presents solution to requirement of implementation of digital metronome in VST technology. In the beginning, there is analysis of basic characteristics of digital metronome, that helps to suggest algorithm realizing digital metronome. Algorithm is encapsulated into C++ class with appropriate interface, which is suitable for usage in different technologies of digital sound signal processing. This way encapsulated metronome is implemented in VST technology as plug-in. For this reason, thesis contains a brief introduction to VST software development kit, definitions of its basic methods and way how to do graphical user interface of VST plug-in. For realizing of function enabling choice of any sound loaded from wav file, there is a description of RIFF format, that specifies the format of saving multimedia data into drive. Using this knowledge, the function of loading from wav file is implemented. In order to adjust sampling frequency of loaded sound, thesis deals with problems of sample rate conversion and implements resampling function.

Metronome for the Android Mobile Device
Pomkla, František ; Burget, Radek (referee) ; Bartík, Vladimír (advisor)
The purpose of this project is the implementation of metronome for smartphone with OS Android and smartwatch with OS Tizen. Both applications provide asynchronous functionality of metronome as well as data sharing through Bluetooth connection. These metronome applications should help musicians in music bands. It allows to save specific song's tempo into playlists and than share them via Bluetooth connection with smartwatch application. The smartwatch application produces vibrations instead of click sound. Other smartphone metronome functionality is to scan drum stroke by internal device microphone and compare it with metronome beat. The programming languages C# and Java with SQLite databases were used for implementation.

Development of mobile application for musicians
Novotný, Miroslav ; Pavlíčková, Jarmila (advisor) ; Kutišová, Magda (referee)
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.
