== Description ==

The aim of the MIREX audio melody extraction
evaluation is to identify the melody pitch contour from polyphonic
musical audio. Pitch is expressed as the fundamental frequency of the
main melodic voice, and is reported in a frame-based manner on an
evenly-spaced time-grid.

The task consists of two parts:

* Voicing detection (deciding whether a particular time frame contains a "melody pitch" or not),
* pitch detection (deciding the most likely melody pitch for each time frame).

We structure the submission to allow these parts
to be done independently within a single output file. That is, it is
possible (via a negative pitch value) to guess a pitch even for
frames that were being judged unvoiced. Algorithms which don't
perform a discrimination between melodic and non-melodic parts are
also welcome!
