description: This qualification work is dedicated to researching current solutions and methods used in the spectral analysis of musical tracks in real time, and implementing new software that extends the capabilities of a digital workstation in terms of visualization of the sound characteristics of a musical work, and simplifying the process of exploring the behavior of frequencies, the structure of sound and its quality. Little-known mathematical algorithms of signal processing, used for creating spectral analyzers of sound, have also been investigated in the course of work. One of such algorithms is the basis of the software module developed in this work. The proposed theme can be called relevant because development of new solutions for arranging the frequency balance, harmonic analysis and optimization of the overall volume of a musical mix in accordance with generally accepted standards is necessary in order to improve the conditions for creating high-quality sound in all formats and on all possible devices and platforms. The plugin was created in C++ in Microsoft Visual Studio 2019 development environment using the cross-platform JUCE Framework. The paper presents conclusions about the performance of the developed program.
