Negative values represent the algorithm's pitch estimate for segments estimated as non-voiced, in case the melody is in fact present there.Ī 2D time-frequency representation of pitch salience over time on a cent scale. Non-voiced segments are indicated by zero or negative frequency values. Each row of the output contains a timestamp and the corresponding frequency of the melody in Hertz. The first (Melody) is computed by the "MELODIA - Melody Extraction" plug-in and the rest by the "MELODIA - Melody Extraction (intermediate steps)" plug-in: MELODIA offers 4 different types of output. The MELODIA vamp plug-in has been made possible by the kind support of the entities mentioned in the acknowledgements.Īudio file in a format supported by your Vamp host (e.g. We would highly appreciate if scientific publications of works partly based on the MELODIA plug-in cite the above publication. Gómez, " Melody Extraction from Polyphonic Music Signals using Pitch Contour Characteristics", IEEE Transactions on Audio, Speech and Language Processing, 20(6):1759-1770, Aug. Both plug-ins are included in a single MELODIA library file available for Windows, OSX and Linux.įull details of the algorithm can be found in the following paper: The former provides the main output of MELODIA (the pitch of the predominant melody), whilst the latter provides visualisations of the intermediate steps calculated by the algorithm (see Input/Output below for further details). The pitch of the melody when it is presentĪ non-scientist friendly introduction to Melody Extraction as well as the algorithm, including graphs and sound examples, can be found on: extractionįor computational reasons, MELODIA is composed of two vamp plug-ins: "MELODIA - Melody Extraction" and "MELODIA - Melody Extraction (intermediate steps)".When the melody is present and when it is not (a.k.a.More specifically, it implements an algorithm that automatically estimates the fundamental frequency corresponding to the pitch of the predominant melodic line of a piece of polyphonic (or homophonic or monophonic) music. The MELODIA plug-in automatically estimates the pitch of a song's main melody.
