   The new approach to the P-wave arrival time determination based on acoustic emission data from loading experiments is tested. The algorithm used in this paper is built on the STA/LTA function computed by a convolution that speeds up the computation process very much. The picking process makes use of shifting of temporary onset until certain conditions are fulfill and as a main decision criterion on the threshold exceeding of the STA/LTA derivation function is used. The P-wave onset time is determined in a selected interval that corresponds to the theoretical propagation of elastic wave in the rock sample. Results obtained by our algorithm were correlated with data acquired manually and a high order statistic software as well.
