In this article the effective method of a single commercial extracting from a advertising block and its recognition using only the audio signal is presented. Proposed algorithm uses a multidimensional orthogonal audio signal representation for a track parametrization. Simulation results for poor commercial audio signal recording conditions and comparison with the known methods are presented. The proposed solution gives a recognition at the level of 98%. This is the result better than the popular methods based on spectral analysis.
