The MIREX (Music Information Retrieval Evaluation eXchange) framework provides a common set of data to evaluate and compare a vast variety of MIR systems. 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(More)
In this paper, a new approach for pitch estimation in polyphonic musical audio is presented. The algorithm is based on the pair-wise analysis of spectral peaks. The idea of the technique lies in the identification of partials with successive (odd) harmonic numbers. Since successive partials of a harmonic sound have well defined frequency ratios, a possible(More)
This extended abstract outlines an efficient approach for the extraction of multiple fundamental frequencies (F0) from polyphonic musical audio. The algorithm consists of three analysis steps. At first a multi-resolution spectral analysis is performed on the audio signal. Then, the most salient pitches are identified using a pitch extraction algorithm,(More)
This paper describes the submission to the MIREX 06 (Music Information Retrieval EXchange) Audio Cover Song task delivered by Fraunhofer IDMT. A method to detect cover songs by comparing the most salient melodies of musical pieces is proposed, based on the assumption that cover versions of one song contain the same melody. To this end, the predominant(More)
The subject of this work is the study of how rhythmical description of music can be included in Music Information Retrieval works, but from a more musical point of view. The goal is to provide a suitable representation of rhythm and explore how useful it can be for many different applications. This new representation is based on the so called Rhythm(More)
We investigated the effects of semantic predictability on children's preservation of the /t/-/d/ phonemic voice contrast in American English. In Experiment 1, a total of 36 seven-, nine-, and twelve-year-olds produced minimal pairs differing in intervocalic /t/ and /d/ in semantically biasing and semantically neutral passages. The seven-year-olds preserved(More)
