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 considers a particle filter based algorithm to extract melody from a polyphonic audio in the short-time Fourier transforms (STFT) domain. The extraction is focused on overcoming the difficulties due to harmonic / percussive sound interferences, possibility of octave mismatch, and dynamic variation in melody. The main idea of the algorithm is to consider probabilistic relations betwee...

BACKGROUND Adverse events from Melody valve implantation may be catastrophic. To date a role for three dimensional rotational angiography of the aortic root (3DRAA) during Melody valve implantation has not been established. OBJECTIVES To describe the role of 3DRAA in the assessment of Melody valve candidacy and to demonstrate that it may improve outcomes. METHODS All patients who underwent ...

Language and music, two of the most unique human cognitive abilities, are combined in song, rendering it an ecological model for comparing speech and music cognition. The present study was designed to determine whether words and melodies in song are processed interactively or independently, and to examine the influence of attention on the processing of words and melodies in song. Event-Related ...

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 problem of automatic melody line identification in a MIDI file plays an important role towards taking QBH systems to the next level. We present here, a novel algorithm to identify the melody line in a polyphonic MIDI file. A note pruning and track / channel ranking method is used to identify the melody line. We use results from musicology to derive certain simple heuristics for the note pru...

This paper focuses on automatic melody transcription in a situation where a chord transcription is already available. Given an excerpt of music in audio form and a chord transcription in symbolic form, the task is to create a symbolic melody transcription that consists of note onset times and pitches. We present an algorithm that divides the audio into segments based on the chord transcription,...

BACKGROUND Follow-up of transcatheter pulmonary valve replacement (TPVR) with the Melody valve has demonstrated good short-term and long-term outcomes, but there are no published studies focused on valve performance in the Contegra bovine jugular vein conduit. METHODS AND RESULTS This is a retrospective, multicenter study of the short- and intermediate-term outcomes of Melody TPVR within the ...

This extended abstract briefly describes the ThinkIT Speech Lab’s submission to the query-by-singing/humming task of MIREX 2007. Our system adopts a three-level framework for retrieving the target song. In such framework, different searching stages employ different melody representations, including acoustic representation for melody scoring, symbolic representation for melody filtering and sent...

Pitch perception is fundamental to melody in music and prosody in speech. Unlike many animals, the vast majority of human adults store melodic information primarily in terms of relative not absolute pitch, and readily recognize a melody whether rendered in a high or a low pitch range. We show that at 6 months infants are also primarily relative pitch processors. Infants familiarized with a melo...
