/Spectrogram-correlation-tutorial

This method uses 2-D template matching to detect a sound signal. The first step is to convert the sound signal into a spectrogram (2-d image) with suitable resolution. Than we need to define a template (also called a kernel) and slide it over the spectrogram to calculate the correlation score (between 0 and 1). All peaks above a certain threshold are than marked as detections.
