It is a multi pitch version of the MELODIA algorithm described in [1].

The approach is based on the creation and characterization of pitch contours, time continuous sequences of pitch candidates grouped using auditory streaming cues. To this end, PitchSalienceFunction, PitchSalienceFunctionPeaks, PitchContours, and PitchContoursMonoMelody algorithms are employed. It is strongly advised to use the default parameter values which are optimized according to [1] (where further details are provided) except for minFrequency, maxFrequency, and voicingTolerance, which will depend on your application.\n"
