In this paper, we investigate the problem of real-time poly-phonic music transcription by employing non-negative matrix factorization techniques and the β-divergence as a cost function. We consider real-world setups where the music signal arrives incrementally to the system and is transcribed as it unfolds in time. The proposed transcription system is(More)
In this article we report on listener categorization of meaningful environmental sounds. A starting point for this study was the phenomenological taxonomy proposed by Gaver (1993b). In the first experimental study, 15 participants classified 60 environmental sounds and indicated the properties shared by the sounds in each class. In a second experimental(More)
While many psychoacoustic studies have found that listeners can recover some causal properties of sound-generating objects (such as the material), comparatively little is known about the causal properties of the sound-generating actions and how they are perceived. This article reports on a study comparing the performance of listeners required to identify(More)
The influence of listener's expertise and sound identification on the categorization of environmental sounds is reported in three studies. In Study 1, the causal uncertainty of 96 sounds was measured by counting the different causes described by 29 participants. In Study 2, 15 experts and 15 nonexperts classified a selection of 60 sounds and indicated the(More)
It is commonly observed that a speaker vocally imitates a sound that she or he intends to communicate to an interlocutor. We report on an experiment that examined the assumption that vocal imitations can effectively communicate a referent sound and that they do so by conveying the features necessary for the identification of the referent sound event.(More)
The aim of the study is to transpose and extend to a set of environmental sounds the notion of sound descriptors usually used for musical sounds. Four separate primary studies dealing with interior car sounds, airconditioning units, car horns and closing car doors are considered collectively. The corpus formed by these initial stimuli is submitted to new(More)
This paper reports on an approach to the design of continuous sonic feedback in tangible interfaces, and on quantitative evaluation methods intended to guide such design tasks. The issues it addresses may be of central relevance to areas of the emerging discipline of sonic interaction design that have begun to address the unique problems of designing sound(More)
In this paper, we investigate the problem of real-time detection of overlapping sound events by employing non-negative matrix factorization techniques. We consider a setup where audio streams arrive in real-time to the system and are decomposed onto a dictionary of event templates learned off-line prior to the decomposition. An important drawback of(More)
Despite being a promising and lively playground, sound design is not a discipline as solid and established as visual or product design. We believe that the reason is to be found in the lack of design-oriented measurement and evaluation tools. The Eu-ropean project CLOSED (Closing the Loop Of Sound Evaluation and Design) aims at providing a(More)
We would liketodedicate this article to the memory of our colleague Suzanne Winsberg Summary This paper is the second of at wo-part study of the quality of car horn sounds. It aims to provide insights into the design of newsounds. It is based on the assumption that hearing acar horn sound warns road users because theyr ecognize the sound of ac ar horn, i.e.(More)
