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...

This paper proposes an algorithm to estimate the melody pitch line (the most dominant pitch sequence) of a given polyphonic audio based on melody range estimation and pitch candidate extraction using a harmonic structure model similar to that proposed by Goto. This paper defines melody pitch candidate as a list of pitch candidates that produces the best-fit harmonic models to the polyphonic aud...

PROMS, a computer-music service under development at the University of Bonn, Germany, aims at designing and implementing PROcedures for Music Search. This paper discusses an eÆcient algorithm for searching a music pattern, e.g., a melody or a sequence of chords, in a large database of polyphonic music, given in a score-like format. Our algorithm is a variant of the now classic inverted le index...

This paper describes our submission to the audio melody extraction evaluation addressing the task of identifying the melody pitch contour from polyphonic musical audio. It shall give an overview about the algorithm and a discussion of the evaluation results. The presented algorithm is a derivative of our submission to MIREX’06. Major changes between the two versions are highlighted and the impa...

in the science of operation research and decision theory, selection is the most important process. selection is a process that studies multiple qualitative and quantitative criteria, related to the science of management, which are mostly incompatible with each other. the multi criteria selection of a renewable energy portfolio is one of the main issues considered in multi criteria literature. i...

This paper considers the proposed algorithm submitted to theMusic Information Retrieval Evaluation eXchange(MIREX) 2011 “AudioMelody Extraction” task. The proposed melody pitch extraction algorithm can be divided into three steps: (1) a spectral analysis using variable length window, (2) a pitch candidate estimation, and (3) a pitch sequence identification. In the first step, the short-time Fou...

The most dominant source in audio is usually perceived as melody. The estimation of it’s fundamental frequency can be treated as melody estimation. The task become difficult when the polyphony of the audio is high. To determine the most dominant source in human perception, perceptual properties have to be accounted. In this algorithm, we applied psychoacoustic property to the data to estimate t...

This paper describes the proposed algorithm submitted to the MIREX 2009 “Audio Melody Extraction” task. The algorithm addresses the task of extracting the predominant melody pitch from a polyphonic audio signal. The algorithm extracts the melody pitch in three steps. In the first step, transient analysis is performed on the polyphonic audio signal to determine the analysis frame length, and the...

cost optimization of the reinforced concrete cantilever soil retaining wall of a given height satisfying some structural and geotechnical design constraints is performed utilizing harmony search and improved harmony search algorithms. the objective function considered is the cost of the structure, and design is based on aci 318-05. this function is minimized subjected to design constraints. a n...
