Speech Analysis for Processing of Musical Signals
Mészáros, Tomáš ; Malenovský, Vladimír (referee) ; Černocký, Jan (advisor)
Hlavním cílem této práce je obohatit hudební signály charakteristikami lidské řeči. Práce zahrnuje tvorbu audioefektu inspirovaného efektem talk-box: analýzu hlasového ústrojí vhodným algoritmem jako je lineární predikce, a aplikaci odhadnutého filtru na hudební audio-signál. Důraz je kladen na dokonalou kvalitu výstupu, malou latenci a nízkou výpočetní náročnost pro použití v reálném čase. Výstupem práce je softwarový plugin využitelný v profesionálních aplikacích pro úpravu audia a při využití vhodné hardwarové platformy také pro živé hraní. Plugin emuluje reálné zařízení typu talk-box a poskytuje podobnou kvalitu výstupu s unikátním zvukem.

Radar-Based Speed Measurement of Sport Projectiles
Bezděk, David ; Široký, Adam (referee) ; Maršík, Lukáš (advisor)
This bachelor's thesis deals with a proposal and implementation of application, that extracts speed information of sport projectiles from radar data. Firstly, there is description of radar, Doppler's effect and especially continuous-wave radar. Then the bachelor’s thesis continues with signal processing issues, after which speed can be calculated.In next part there is a describtion of collecting real data and their evaluation. In the last part there is a summary of the thesis, eventual use of the application and it's possible extensions.

Mobile Application for Learning to Play Drums
Novotný, Jan ; Zemčík, Pavel (referee) ; Beran, Vítězslav (advisor)
This bachelor thesis aims to design and create a mobile application for teaching percussion playing and rhythmic reading training. The application contains several lessons with exercises that are displayed in the form of music notation. It is made possible to play and practice individual exercises accompanied by a metronome. Furthermore, it offers an analysis of the play on the instrument and provides feedback on the quality of playing. The application is developed on the Xamarin platform for use on Android and iOS operating systems. The result of this work is an application that will serve drummers to practice and provide an evaluation of the accuracy of the played exercise and thus will help to improve their playing skills.

Deep learning based sound records analysis
Kramář, Denis ; Říha, Kamil (referee) ; Přinosil, Jiří (advisor)
This master thesis deals with the problem of audio-classification of the chainsaw logging sound in natural environment using mainly convolutional neural networks. First, a theory of grafical representation of audio signal is discussed. Following part is devoted to the machine learning area. In third chapter, some of present works dealing with this problematics are given. Within the practical part, used dataset and tested neural networks are presented. Final resultes are compared by achieved accuracy and by ROC curves. The robustness of the presented solutions was tested by proposed detection program and evaluated using objective criteria.

EEG Analysis During Anaesthesia
Hodulíková, Tereza ; Kolářová, Jana (referee) ; Sadovský, Petr (advisor)
This master's thesis deals with the method of functional examination of brain electric activity. In the first part is description of central nervous system, method of electroencephalography and possible connections. Furthermor the project involves characteristic of EEG signal and its artifacts. It also includes signal processing and list of symptoms, which will be used for an analysis of the EEG during anesthesia. The second part of thesis involves development of application, which allow viewing and proccesing of EEG signal. In conclusion of thesis is carried out unequal segmentation and statistical processing.

Granular Synthesis in Music Production
Pečinka, Pavel ; Glembek, Ondřej (referee) ; Černocký, Jan (advisor)
Cílem této práce je navrhnout a vytvořit aplikaci pro granulární syntézu, využitelnou v hudbení produkci. Aplikace je implementována jako VST3 zásuvný modul s využitím frameworku JUCE a programovacího jazyka C++ a je schopná propojení s programy typu Digital Audio workstation, zkráceně DAW, což jsou programy sloužící jako centrální bod pro hudební producenty, kde mohou mimo jiné vytvářet nové zvuky, provádět mixování skladeb a vytvářet zvukové nahrávky. Tento zásuvný modul je navržen jako sampler a je schopen nahrát zvukový soubor obsahující audio data, která dále využívá pro další zpracování a následné přehrávání. Z vyhodnocení uživatelského testování vyplývá, že je tato aplikace použitelná pro hudební produkci jako nástroj pro granulární syntézu.

Signal processing in ZigBee system
Miloš, Jiří ; Bradáč, Zdeněk (referee) ; Hanus, Stanislav (advisor)
Master's thesis The Signal Processing in ZigBee System is focused on properties of Physical Layer of ZigBee (standard IEEE 802.15.4 - 2003). The work consists of three parts. The first part contains common view on using and properties of ZigBee. The next part focuses on the Medium Access Control Layer and in detail on the Physical Layer. There described signal processing in the Physical Layer in individual radio bands. The last part of the project contains the process of modeling in the MATLAB for both models of system ZigBee (bands 868/915 MHz and 2450 MHz). The last part of thesis deals with the simulations of BER depending on Carrier-to-Noise Ratio. Also examined the coexistence of systems operating in the same or a nearby frequency band. Based on the results of simulations there are given recommendations for the use of the ZigBee system in minimizing BER.
