Method and system for identifying a matching signal

A system for identifying a matching signal from a signal bank comprising a plurality of signals, to a first signal, the system comprising;

• A processor configured to perform the steps of;
• Receiving, by a processor, the first signal and the plurality of signals from signal bank from which a matching signal to the first signal is to be searched;
• Performing, by the processor, a spectral analysis of the first signal and the plurality of signals, the spectral analysis comprising;
• Computing a chromatogram comprising a plurality of frames;
• Splitting each of the plurality of frames into a plurality of pitch classes;
• Analyzing each of the plurality of pitch classes;
• Determining dominant pitch class from the plurality of pitch classes, wherein the dominant pitch class has highest frequency magnitude;
• and
• Matching, by the processor, dominant pitch class of the first signal with dominant pitch class of at least one of the plurality of signals.

A non-transitory computer-readable storage medium providing matching of signals, when executed by a computing device, cause the computing device to:

• Receive a first signal and the plurality of signals from signal bank from which a matching signal to the first signal is to be searched;
• Perform a spectral analysis of the first signal and the plurality of signals, the spectral analysis comprising;
• Computing a chromatogram comprising a plurality of frames;
• Splitting each of the plurality of frames into a plurality of pitch classes;
• Analyzing each of the plurality of pitch classes;
• Determining dominant pitch class from the plurality of pitch classes, wherein the dominant pitch class has highest frequency magnitude;
• and
• Matching dominant pitch class of the first signal with dominant pitch class of at least one of the plurality of signals.
