Melody Extraction in Music Audio Signals by Melodic Component Enhancement and Pitch Tracking

چکیده
This extended abstract is for the “Audio Melody Extraction” contest of MIREX2009. We describe an algorithm that estimates the melody line from a music audio signal. The algorithm is comprised of two stages: melodic component enhancement and melody line tracking. Only a few researchers used this approach because of difficulties of the melody enhancement. Our enhancement algorithm focuses on temporal vaiability of melodic source, e.g., vibrato of singing voice, violin, etc. After enhancement, we estimate the melody line by a simple tracking algorithm. The method is evaluated in MIREX2009, and it is confirmed that the method is effective if the melody is played by singing voice, especially in low SNR conditions.

متن کاملStatistical Characterisation of Melodic Pitch Contours and its Application for Melody Extraction
In this paper we present a method for the statistical characterisation of melodic pitch contours, and apply it to automatic melody extraction from polyphonic music signals. Within the context of melody extraction, pitch contours represent time and frequency continuous sequences of pitch candidates out of which the melody must be selected. In previous studies we presented a melody extraction alg...
متن کاملApplications of a Semi-automatic Melody Extraction Interface for Indian Music
Automatic extraction of the melody from polyphonic music recordings is a challenging problem for which no general solutions currently exist. We present a novel interface for semi-automatic melody extraction with the goal to provide highly accurate pitch tracks of the lead voice with minimal user intervention. Audio-visual feedback facilitates the validation of the obtained melodic contour, and ...
متن کاملImproving Polyphonic Melody Extraction by Dynamic Programming Based Dual F0 Tracking
The suitability of optimal path finding methods for vocal melody extraction in polyphonic music is well recognized since they combine local pitch strength and temporal smoothness considerations in a global sense. However, when such single-F0 tracking systems are applied to sound mixtures in which pitched accompaniment is of comparable strength to the singing voice, they suffer from irrecoverabl...
متن کاملMelody Description and Extraction in the Context of Music Content Processing
A huge amount of audio data is accessible to everyone by on-line or off-line information services and it is necessary to develop techniques to automatically describe and deal with this data in a meaningful way. In the particular context of music content processing it is important to take into account the melodic aspects of the sound. The goal of this article is to review the different technique...
