MIDI transducer design and cymbal colour upgrade with artificial components
Pospíšil, Martin ; Buzzi, Mário (referee) ; Jirásek, Ondřej (advisor)
This bachelor thesis deals with MIDI transducer design and cymbal color innovation with artificial components. The goal of the thesis was to design and fabricate a converter that converts audio signals from cymbals to the MIDI standard while capturing the widest dynamic range. Furthermore, a spectral analysis of several types of cymbals was performed and a program was created that adds artificial components such as filtered noise and additive inharmonic clusters to their acoustic color. The result of this work is a working prototype MIDI transducer and a program implemented in NI Reaktor software that allows the creation of acoustic presets with the upgraded cymbal color. The work met the stated objectives and provided a basis for further development in this area.

Experimental electroacoustic musical instrument
Hrdlička, Matěj ; Dlouhý, Dan (referee) ; Indrák, Michal (advisor)
This bachelor thesis deals with the design and construction of an experimental electroacoustic musical instrument inspired by analogue synthesizers from Dubreq -- stylophones. In contrast to the original stylophones, this Stylophone processes the audio signal in digital form. Stylophone contains two independent sound generators, which are two Arduino NANO development boards. In the theoretical part of the thesis, the historical development of the models of the original stylophones is described and the circuitry and sound generation method of the original Stylophone from 1968 is described. The practical part describes the circuit design, PCB, Arduino code and device construction. Also described are the different sounds generated by the instrument, their frequency analysis and a comparison of the sound character of the instrument with the sound analysis of the original Stylophone S1 from Dubreq. The last chapter of the thesis deals with the description of the techniques of playing the Stylophone and their notation.

VST granular plugin with experimental input and output settings
Kalinič, Jan ; Dlouhý, Dan (referee) ; Indrák, Michal (advisor)
This thesis discusses the development of a plug-in module that is able to implement granular synthesis with help of experimental methods of parameter value settings. Graphic designs and schemes were created in the vector graphics editor Inkscape. The separate plug-in was programmed in C++ language using the JUCE framework and VST3 technology. With a use of this module, granular synthesis can be performed over a predetermined sample, but also over the stream of an audio channel of a digital audio station. The module also includes blocks with other types of sound synthesis, which can also be modified in experimental ways. Thanks to its properties, the plug-in can be applied as an effect over one sound channel in the mixing section of an audio station.

FITkit Music Synthesizer
Melichar, Vojtěch ; Minařík, Miloš (referee) ; Vašíček, Zdeněk (advisor)
This bachelor's thesis deals with sound synthesis methods and with design of a synthesizer for FITkit platform. In the first part of the thesis, there are described methods of sound synthesis and the history of sound synthesis is also stated here. Next part contains a brief characteristic of sound chip SID 6581. In the next part of the thesis, there is a design of each part of the synthesizer: oscillator, envelope generator, voice and filter. Then, these components are put together to make up an synthesizer. Correctness of the implementation is verified by a simulation in ModelSim 6.6d. Individual components are simulated separately and then in mayor groups.

Algorithms for Synthesis of Musical Sounds
Novák, Samuel Matyáš ; Heriban, Pavel (referee) ; Roupec, Jan (advisor)
This work concerns the problem of synthesizing musical sounds, specifically the problem of designing oscillator algorithms. The problem is approached from the perspective of function composition and phase distortion. Interpolation polynomials, iteration methods and optimization were employed when designing the necessary functions. Phase accumulator and a sine waveshaping function were constructed. Furthermore, a way of distorting the sine waveform was presented. Finally, a method of synthesizing detuned voices of a sawtooth wave was described.
