This bachelor’s thesis deals with the creation of two web applications demonstrating the Doppler effect and the comb filter. The aim of the thesis was to create applications suitable for interactive teaching support in topics related to the propagation and processing of sound waves. The applications combine visual and audio elements in order to make these phenomena easier to understand. The thesis first presents the theoretical background of both phenomena. In the case of the Doppler effect, it explains the change in observed frequency caused by the relative motion between a source and a receiver. In the case of the comb filter, it describes its formation by combining a direct signal with a delayed signal, as well as the influence of the delay on the frequency response of the filter. The thesis then describes the functions of the created applications, their user interface, and the logic of the program code. It explains the calculation of the required parameters, the processing of audio signals, and the graphical representation of the simulated phenomena. The applications were created using HTML, CSS, and JavaScript, with the p5.js and Tweakpane libraries. The audio components were programmed using the Web Audio API.
