Introduction

These are the results for the 2006 running of the Audio Melody Extraction task set. For background information about this task set please refer to the Audio Melody Extraction page.

The aim of the MIREX audio melody extraction evaluation is to identify the predominant melody pitch contour from polyphonic musical audio. The task consists of two parts: Voicing detection (deciding whether a particular time frame contains a "melody pitch" or not), and pitch detection (deciding the most likely melody pitch for each time frame). We structure the submission to allow these parts to be done independently, i.e. it is possible (via a negative pitch value) to guess a pitch even for frames that were being judged unvoiced. The algorithms were tested on two datasets, the MIREX2005 dataset, consisting of 25 sound files, and the ADC2004 dataset, consisting of 20 sound files, both across different music styles. Moreover, each of these datasets were split into two groups: those files in which the predominant melody is sung, and those in which the predominant melody is nonvocal.

dressler = Karin Dressler
ryynanen = Matti Ryynänen and Anssi Klapuri
poliner = Graham Poliner and Daniel P. W. Ellis
sutton = Christopher Sutton, Emmanuel Vincent, Mark D. Plumbley and Juan P. Bello
brossier = Paul Brossier

  • Brossier does not do voiced/unvoiced detection.
  • Sutton's algorithm is designed for sung/vocal melody extraction.
