Web applications supporting education of audio signals generation and processing
Tkadlec, Vojtěch ; Schimmel, Jiří (referee) ; Rajmic, Pavel (advisor)
The main goal of the diploma thesis was the creation of 3 web applications for interactive support of studying courses in the area of digital signal processing using the programming language JavaScript, the markup language HTML, and the Web Audio API interface. The topics included additive synthesis, ADSR time envelope, amplitude modulation, and approximation of 1D signals using discrete cosine transform. The written part of the thesis also focuses on the tools used for the practical part of the thesis. For better understanding of the topics, four web applications were created, and a separate web application was created specifically for the topic of ADSR envelope.
Design and Realization of Acoustic Treatment of Small Recording Studio
Tkadlec, Vojtěch ; Husník, Libor (referee) ; Schimmel, Jiří (advisor)
This bachelor thesis deals with the topic of acoustic properties of an enclosed space, their detection and modification. The thesis examines the acoustic properties of a small enclosed space, which were determined by simulation using a virtual 3D model and subsequently verified by measurement. After finding out the properties, a substantial part was also devoted to their modification, where the task was to design the acoustic elements so that the resulting length of the reverberation time corresponds to the optimal values for a small recording studio. The design of the elements is followed by their construction, followed by a re-measurement of the space. Furthermore, the work summarizes the principles of modeling and simulation of 3D models.
