Perceptual evaluation of multi-dimensional spatial audio reproduction.
Perceptual differences between sound reproduction systems with multiple spatial dimensions have been investigated. Two blind studies were performed using system configurations involving 1-D, 2-D, and 3-D loudspeaker arrays. Various types of source material were used, ranging from urban soundscapes to musical passages. Experiment I consisted in collecting subjects' perceptions in a free-response...
متن کاملPerceptual Evaluation of Spatial Audio: Where Next?
From the early days of reproduced sound, engineers have sought to reproduce the spatial properties of sound fields, leading to the development of a range of technologies. Two-channel stereo has been prevalent for many years; however, systems with a higher number of discrete channels (including rear and height loudspeakers) are becoming more common and, recently, there has been a move towards lo...
متن کاملPerceptual Spatial - Audio Coding
A novel technique for the perceptual coding of spatial audio is presented. This coding technique allows individualized 3D audio presentation and exploits the dichotomous roles of the lowfrequency interaural timing and level difference cues versus the high-frequency spectral cues in human sound localization. The high-frequency spectral cues are modified to match the acoustics of the listener’s o...
متن کاملSpatial Audio Reproduction: Towards Individualized Binaural Sound
INTRODUCTION The compact disc (CD) format records audio with 16-bit resolution at a sampling rate of 44.1 kHz. This format was engineered to reproduce audio with fidelity exceeding the limits of human perception, and it works. However, sound is inherently a spatial perception. We perceive the direction, distance, and size of sound sources. Accurate reproduction of the spatial properties of soun...
متن کاملVirtual audio Reproduction Engine for Spatial Environments
Topic of this paper is an interactive sound reproduction system to create virtual sonic environments and visual spaces, called Virtual Audio Reproduction Engine for Spatial Environments (VARESE). Using VARESE, Edgard Varèse’s Poème électronique was recreated within a virtual Philips Pavilion. The system draws on binaural sound reproduction principles including spatialization techniques based on...
