Signal Processing for Spatial Sound Reproduction with Wave Field Synthesis
Wave Field Synthesis is a technique for spatial sound reproduction that overcomes the limitations of classical stereophonic techniques. A thorough analysis of acoustic wave propagation prinicples delivers the technical description in terms of loudspeaker array technology. Suitable signal processing methods convert the source signals into driving signals for each loudspeaker. The suitability of ...
متن کاملCompact Loudspeaker Array for Enhanced Stereophonic Sound Reproduction
This paper illustrates the demonstration of sonic emotion 3D sound technology for compact loudspeaker arrays. The technology combines stereo/5.1 spatial analysis techniques with advanced sound field control techniques based on Wave Field Synthesis for optimum sound rendering of stereo/5.1 content within an extended listening area. sonic emotion offers a complete solution in the form of a chip t...
متن کاملStereophonic Personal Audio Reproduction Using Planarity Control Optimization
Sound field control to create multiple personal audio spaces (sound zones) in a shared listening environment is an active research topic. Typically, sound zones in the literature have aimed to reproduce monophonic audio programme material. The planarity control optimization approach can reproduce sound zones with high levels of acoustic contrast, while constraining the energy flux distribution ...
متن کاملSelective Listening Point Audio Based on Blind Signal Separation and Stereophonic Technology
A sound field reproduction method is proposed that uses blind source separation and a head-related transfer function. In the proposed system, multichannel acoustic signals captured at distant microphones are decomposed to a set of location/signal pairs of virtual sound sources based on frequency-domain independent component analysis. After estimating the locations and the signals of the virtual...
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...
