Our system is able to visualize the signals of mechanical and electrical resonances and their spectra in real time. We give a brief description of the system, and show some examples of electrical and mechanical resonance experiments that are supported by the system. The theoretical background, experimental set-up, component selection and digital signal processing are all discussed, and more detailed information (building instructions, software download) is provided on a dedicated web page ( www.noise.inf.u-szeged.hu/edudev/RealTimeAnalysisOfResonances/ [http://www.noise.inf.u-szeged.hu/edudev/RealTimeAnalysisOfResonances/] ). The experimental set-up can support the undergraduate and graduate education of students of physics, physics education and engineering by means of experimental demonstrations and laboratory exercises. The very low cost, high efficiency and transparent system provides a scalable experimental environment that can be easily built in several instances.1 aMakan, Gergely1 aKopasz, Katalin1 aGingl, Zoltán  uhttps://tisat.inf.u-szeged.hu/publication/real-time-analysis-of-mechanical-and-electrical-resonances-with-open-source-sound-card-software
