Abstract: A method of and system for increasing the reliability of signal detection, that includes receiving at least one audio recording comprising at least one sound marking signal and performing waveform analysis on the sound marking signal to determine whether the sound marking signal is fragmented into a plurality of signal portions. If the sound marking signal is fragmented into a plurality of signal portions, the method further includes confirming that portions of the fragmented sound marking signal possess characteristics of a sinusoidal signal.
