—The following article addresses a software package developed for working with data obtained during monitoring the detection of material defects via the acoustic emission (AE) method. Timely detection of cracks allows to prevent contingencies and accidents at early stages. This paper describes the architecture of this software, as well as the used calculation methods, provides visualized results of their work, and compares them with other analysis methods. The innovation of this work is the use of the moving window method for AE data analysis. Obtained results indicate the practical importance and relevance of our research in this area.
