Vyhodnocování a vizualizace frekvenčního spektra zvuku

Abstract

The aim of the diploma thesis is to familiarize with methods of processing and evaluating audio signals. For signal processing and evaluation, the ESP32 development kit will be used. Processed signals will be visualized using moving ping-pong balls in a transparent tube, where these balls represent the strength of the signal in different frequency spectra. The signal is divided into three spectra representing sound levels (bass, midrange, treble).
