This paper reports on the types and magnitudes of localization errors of simulated binaural direction cues generated using non-individualized, head-related transfer functions (HRTFs) with different levels of complexity. Four levels of complexity, as represented by the number of non-zero coefficients of the associated HRTF filters (128, 64, 32, 18 non-zero… (More)
Individualised head-related transfer functions (HRTFs) have been shown to accurately simulate forward and backward directional sounds. This study explores directional simulation for non-individualised HRTFs by determining orthogonal HRTFs for listeners to choose between. Using spectral features previously shown to aid forward-backward differentiation, 196… (More)
agent is evaluated in live sessions with music ensembles.
The human binaural system has a number of astonishing capabilities that are essential for the formation of our aural worlds. To mimic these, signal-processing models of the binaural system have been built and are constantly improved. In the following, the current state of the art of these models will be reviewed and their potential with respect to practical… (More)
Although there have been numerous studies investigating subjective spatial impression in rooms, only a few of those studies have addressed the influence of visual cues on the judgment of auditory measures. In the psychophysical study presented here, video footage of five solo music/speech performers was shown for four different listening positions within a… (More)
The acoustic modality is of paramount importance for human inter-individual communication. Consequently , the human auditory system is highly differentiated and able to perform sophisticated tasks such as the identification, recognition and segregation of concurrent sound sources in acoustically adverse conditions – e.g., in reverberant or noisy… (More)
Purpose – The purpose of this paper is to better understand communication between musicians in a free jazz improvisation in comparison to traditional jazz. Design/methodology/approach – A cybernetic informative feedback model was used to study communication between musicians for free jazz. The conceptual model consists of the ears as sensors, an auditory… (More)
