Timbre and emotion are two of the most important aspects of musical sounds. Both are complex and multidimensional, and strongly interrelated. Previous research has identified many different timbral attributes, and shown that spectral centroid and attack time are the two most important dimensions of timbre. However, a consensus has not emerged about other dimensions. This study will attempt to i...

The present study uses the envelope modulation spectrum (EMS) measure to assess the effect of language, speaking style, and age on rhythm. Three experiments using a weighted mean of the EMS called the spectral centroid were conducted. The first examined rhythm in English and Croatian across conversational and clear speaking styles. The second experiment compared rhythmic characteristics of mono...

synthetic aperture radar (sar), which has been widely used for earth remote sensing, provides high resolution, day-and-night and weather-independent images for a multitude of applications. design of sar sensors has had some considerations, associated to sar systems issues (microwave propagation, antenna, orbit design and etc.). altitude and attitude errors of sar sensor have a direct effect on ...

This paper reconfirms that talker identity can be transmitted across languages. Talker discrimination was examined in the ABX paradigm, where the stimuli A and B were utterances by different talkers in the same language and the stimulus X was an utterance by either of A or B in the different language. The average hit rate of this discrimination task was as high as 0.89. The mutual distance matr...

This paper presents an experiment on sound tracing, meaning an experiment on how people relate motion to sound. 38 participants were presented with 18 short sounds, and instructed to move their hands in the air while acting as though the sound was created by their hand motion. The hand motion of the participants was recorded, and has been analyzed using statistical tests, comparing results betw...

Music conveys emotions by means of pitch, rhythm, loudness, and many other musical qualities. It was recently confirmed that timbre also has direct association with emotion, for example, that a horn is perceived as sad and a trumpet heroic in even isolated instrument tones. As previous work has mainly focused on sustaining instruments such as bowed strings and winds, this paper presents an expe...

A simplex-centroid design for q mixture components comprises of all possible subsets of the q components, present in equal proportions. The design does not contain full mixture blends except the overall centroid. In real-life situations, all mixture blends comprise of at least a minimum proportion of each component. Here, we introduce simplex-centroid designs which contain complete blend...

This paper investigates the dependence of perceived timbral brightness on pitch and spectral centroid for single notes and pairs of simultaneous notes. In both cases, brightness is better correlated with the spectral centroid fc than with the ratio of fc to the pitches of the notes.

A method for improving centroid-based clustering is suggested. The improvement built on diversification of the k-means++ initialization. algorithm claimed to be a better version k-means tested by computational set-up, where dataset size, number features, and clusters are varied. statistics obtained testing have shown that, in roughly 50 % instances cluster, outputs worse results than with rando...
