For pattern recognition in acoustic recordings, a recorded signal is decomposed into individual frequency ranges and subsequently transformed for spectral decomposition into at least one coefficient file. Here, a first transformation optimized with respect to the frequency resolution and a second transformation optimized with respect to the time resolution take place in parallel. On the basis of the coefficient file, a harmonic decomposition with pattern assignment is effected. The identified patterns can subsequently be modified and further used, for example, in the form of graphic representation or acoustic playback.
