Tracking melody in polyphonic audio. MIREX 2008
Pablo Cancela · 2008
In this work a melody extraction technique is introduced to the MIREX 2008 campaign. The task’s objective consists in estimating the pitch of the main melody in polyphonic audio. The proposed method is based in three separate modules. The first one evaluates the presence of quasi-stationary harmonic sources in a frame level based approach. Next, sources are tracked using the output of the first step, obtaining a set of pitch contours. In the last step, it is decided whether or not each contour at each time is part of the main melody.
