Design and Construction of Transmission Line Loudspeaker Cabinet
Dobiášovský, Jiří ; Schimmel, Jiří (referee) ; Balík, Miroslav (advisor)
Thesis is dealing with the topic of design and construction of the transmission line loudspeaker enclosures. Theoretical part is focused on speaker choice, its design elements and their influence on parameters of the speaker. Individual parameters of the speaker, mathematical equations for their determination and choice of suitable speaker for transmission line loudspeaker enclosure is furthermore discussed and defined. Principle of transmission line enclosures is discussed together with its advantages and disadvantages compared to other types of enclosures. The individual design elements and their influence on the resulting characteristics of the enclosure are described. In the practical part, with regard to the facts stated in the theoretical part of the work, a suitable speaker is selected and the subsequent design and construction of a variable transmission line speaker is described. This might serve as a teaching aid in future. Part of the work is also a description of procedures for measuring loudspeakers with multiple speakers or resonators.

Audio Data Interpretation in Image and Video
Dobiášovský, Jiří ; Balík, Miroslav (referee) ; Říha, Kamil (advisor)
The content of the thesis is the elaboration of the problem of image and video interpretation of sound data. In the theoretical part, the topic of the sound signal, its properties and the representation of the sound signal in the time and frequency domain are treated first. Furthermore, its digital processing is described and individual communication protocols with which it is possible to transmit audio data or communicate with audio and video devices are described too. Based on the findings from the theoretical part, a suitable system is chosen for 3D generative visualization of the sound signal based on MIDI data or its envelope. A system is created for processing sound data in the DAW and sending it over the local network using a suitable protocol. In the environment chosen for visualization is created a program that receives the sent signals and sorts them appropriately. The process of creating visual effects is described, the method of their use in the visualization of the audio signal and mutual communication between the two programs is demonstrated using suitable examples and pilot project. The system resulting from this work can be used for real-time 3D generative visualization of music data.
