Design and construction of a simple music synthesizer
Ondryáš, Radek ; Čudek, Pavel (referee) ; Čech, Ondřej (advisor)
This paper deals with the topic of synthesizers. The first part of the paper provides a general description of synthesizers, their history, types, and important components. The next part of this paper focuses on sound generator chip Texas Instruments SN76477, specifically it’s functionality and ways of controlling its functions. The main part of this paper is designing and creating a synthesizer around the SN76477 sound chip and creating a box for the synthesizer from laser cut plywood.

Experimental Hardware Musical Instrument Based on FM Synthesis Controlled by a Contactless Controller
Vejvoda, Zdeněk ; Jirásek, Ondřej (referee) ; Dlouhý, Dan (advisor)
The focus of this bachelor thesis was a design and consequently an assembly of an experimental analog synthesizer. The beginning of the theoretical framework presents the classification of the electroacoustic instruments into subgroups with an emphasis on those which were essential for both the inspiration of the design and for the historical development itself. The subsequent chapter explores the sound synthesis methods and their musical attributes. Afterwards, particular fundamental personae of the history of experimenting with sound and music are mentioned, whose ideas were extracted for the purpose of designing this instrument. The practical part explains the motivation which was present during the work and develops it into a full circuit design. The creative process is supported by explanation of attached diagrams and required calculations. In connclusion, the assembled prototype is presented on a printed circuit board.

Experimental Software Musical Instrument on Android Platform with Ability to Control Parameters by Text Conversion
Rychtecký, Václav ; Indrák, Michal (referee) ; Dlouhý, Dan (advisor)
The purpose of the thesis is to create a mobile application on the Android platform, characterized by creation of sound using a text captured by a built-in camera of the device in combination with synthesizer, sequencer and sampler. The implementation is partly based on a design prepared within a semestral thesis and is divided into several parts. The first part briefly describes the types of syntheses, the Android operating system, the Pure Data programming language, MIDI and the Android library for controlling Pure Data. The second part deals with the design of the application and the third part describes the implementation and especially the functionality of the application which is created using the programming language Kotlin and IDE Android Studio from JetBrains in combination with the language Pure Data.

Experimental hardware musical instrument demonstrating possible means of colour sonification
Rezek, Václav ; Jirásek, Ondřej (referee) ; Dlouhý, Dan (advisor)
The goal of this thesis was to design and build an experimental musical instrument SuperDuperRainbowThing. The experiment nature of which lies in sonification of the colour spectrum. The hardware is built using Arduino microcontroller and a single board computer Raspberry Pi. Software communicates with the hardware via a MIDI protocol and is written in Python programming language and patched in Pure Data graphical environment. The instrument creates a sound output based upon colour selected by the user in real time.

Modular Analog Synthesizer
Jambor, Tomáš ; Vrba, Kamil (referee) ; Schimmel, Jiří (advisor)
The aim of this work is to get acquainted with the principle of modular analog synthesizers and circuit design used in these devices. The subtractive synthesis was chosen like a main method, which is based on a modular design principle. The theoretical part include brief history of synthesizers and electronic musical instruments, review of other methods of synthesis and detailed elaboration of principles and modules used in subtractive synthesis. The practical part of this work is implementation and measuring properties of the module voltage controlled oscillator, voltage controlled filter, low frequency oscillator and voltage controlled amplifier. There is additionally implement calculation and design circuitry for voltage controlled amplifier.

Musical Signal Synthesis on Android
Mikulík, Jan ; Glembek, Ondřej (referee) ; Černocký, Jan (advisor)
The main task of this thesis is to design and implement new synthesizer on mobile platform under Android. The synthesizer generates three types of signals - sine, sawtooth and square. Two types of filters can be applied, low pass and high pass, and their cut-off frequency can be controlled. For the sound interpretation, an AudioTrack API was used. The synthesizer is controlled by zones, where one zone equals one tone. Zones can be selected by the user. For this synthesizer, a simple user interface was created.

DRM signal receiver
Mik, Šimon ; Charvát, Jiří (referee) ; Šnajdr, Václav (advisor)
The master’s thesis deals with the design of DRM (Digital Radio Mondiale) receiver. The block diagram of receiver was chosen and particular blocks were theoretically analyzed. After that followed design and production of each block. The synthesizer was programmed and the receiver properties were verified. The last part of thesis deals with real receiving of DRM broadcast.
