The purpose of this paper is to provide an overview of sonification research, including the current status of the field and a proposed research agenda. This paper was prepared by an interdisciplinary group of researchers gathered at the request of the National Science Foundation in the fall of 1997 in association with the International Conference on(More)
The real world presents our sensory systems with a continuous stream of undifferentiated information. Segmentation of this stream at event boundaries is necessary for object identification and feature extraction. Here, we investigate the neural dynamics of event segmentation in entire musical symphonies under natural listening conditions. We isolated(More)
音色は「ラウドネスとピッチが同じ二つの音 を、等しい条件で提示した際に、違いが聴取さ れるための特質」と定義される [1]。本稿では、 音の知覚において音色の役割を研究する際に重 要である、音色知覚の多次元性について論じる。 3種類の音色推定手法と、音色知覚との関連性 を比較検討した。 研究の動機として以下の二つが挙げられる。 基礎研究としては、人間がどのように音と言語 を知覚するのか理解し、色覚における三刺激値 モデルと同等な音色知覚モデルを作りたい。そ して応用のためには、よりよい音の分析のため に最節約性を満たす基礎的な音色の数値表現を 見つけたい。 この研究では音色の知覚について、これまで の研究とは異なったアプローチをとる。多次元 尺度法を用いた音色の研究 [2, 3, 4]では、まず(More)
Since 2000, access to antiretroviral drugs to treat HIV infection has dramatically increased to reach more than five million people in developing countries. Essential to this achievement was the dramatic reduction in antiretroviral prices, a result of global political mobilization that cleared the way for competitive production of generic versions of widely(More)
A goal of sonification research is the intuitive audio representation of complex, multidimensional data. The authors present two facets of this research that may provide insight into the creative process. First, they discuss aspects of categorical perception in non-verbal auditory scene analysis and propose that these characteristics are simplified models(More)
We present a hybrid method in which we classify music from a raw audio signal according to their spectral features, while maintaining the ability to assess similarities between any two pieces in the set of analyzed works. First we segment the audio file into discrete windows and create a vector of triplets respectively describing the spectral centroid, the(More)
Raster scanning is a technique for generating or recording a video image by means of a line-by-line sweep, tantamount to a data mapping scheme between one and two dimensional spaces. While this geometric structure has been widely used on many data transmission and storage systems as well as most video displaying and capturing devices, its application to(More)
