Parametrizable Music Instrument for Mobile Platforms
Řezáč, Martin ; Mlích, Jozef (referee) ; Černocký, Jan (advisor)
The goal of this thesis is to create an application, which will be primarily used as three-axis parametrizable musical instrument, respectively a modifi ed MIDI controller, suitable for Android devices. Firstly, several products, which are available on the market, are reviewed and the reader is introduced to the problematics of audio synthesis, available technologies and typical Android device potential. The next chapter is dedicated to application design. Few designs are mentioned with focus on the chosen design concept. A part of this chapter is also a speci cation of the original concept, its implementation and advantages/disadvantages. The next part is dedicated to implementation and optiomalization of some of the critical points. Also the tests are evaluated including a survey about application usability. At the end, the whole work is concluded and the further development is outlined.

Software for Digital Mixing Console
Zoň, Robin ; Přinosil, Jiří (referee) ; Schimmel, Jiří (advisor)
This thesis describes the design and implementation of a software for digital mixing console built on the Windows platform. This software is designed to offer real-time multi-channel audio processing using multiple input and output units, signal routing between these units and insertion and management of VST plug-in modules. The software uses an audio interface connected with ASIO technology. The thesis is divided into several applications. Main application which computes audio samples and allows insertion and management of plug-ins is programmed in C++ using JUCE technology. This application can be controlled with its own local graphical interface or with web control interface, which is programmed in TypeScript with the use of React technology. Web interface allows user to control VST plug-in modules with its own custom implementation of plug-in control.

Real-Time Audio Signal Processing in Embedded Computer
Novák, Pavel ; Trzos, Michal (referee) ; Schimmel, Jiří (advisor)
The Bachelor thesis deals with operating systems, particularly with Windows Embedded Standard 7 for built-in computers. The first part of the thesis is focused on the most compact installation development. The second one is oriented on sound card and sound interface ASIO driver installation. The application for the real time sound processing inTone is also described in detail there.

Chord recognition
Soudek, Ondřej ; Glembek, Ondřej (referee) ; Černocký, Jan (advisor)
The goal of this bachelor thesis is to create an application, that will perform a real-time analysis of a signal from electric or acoustic guitar and will recognize a chord or tone, played by user. This document contains basics of music theory and the solution of the problem, as well as the results of testing.

Software Analyzer for Audio Effects
Frenštátský, Petr ; Sysel, Petr (referee) ; Schimmel, Jiří (advisor)
The utilisation of personal computers for a conditioning of audio devices has shown a significant increase, since the digital signal processing (DSP) was introduced. The expansion of the DSP has allowed implementing analyses to obtain frequency and linear characteristics, distortion parameters (THD, THD+N, WHD, SINAD), a rate of crosstalk or a signal-to-noise ratio. In this work a software analyser is developed, which is able to obtain qualitative parameters of hardware audio devices that are connected with a sound card. For an efficient communication between the sound card and the personal computer the ASIO driver is used. The application is capable to measure audio effects that are implemented in VST plug-ins. The software is developed in C++ language and the implemented analyses are based on the AES17 recommendation.
