• The present chapter discusses the parameter-based analysis of AE. This is particularly useful in case full waveform recording is not available, or the acquisition rate is not sufficient to allow waveform streaming. Parameter analysis is based on extraction of descriptors that contain most of the waveform information, without however, the need to store the whole number of points, essentially contributing to data management. The different parameters are introduced and their relation to fracture mode as well as their use for process characterization are discussed in detail. In addition, well established indices based on the total AE activity are also discussed to demonstrate the complete arsenal of AE parametric analysis that has proven very useful to researchers and practitioners, in different material systems.
