Dirt Cheap 3D Spatial Audio

چکیده
The advent of affordable sophisticated audio solutions for the home PC market has paved the way for low-cost true three-dimensional spatial audio, which can produce a sound effect from any 3D position source. The home entertainment market has guided the development of audio solutions for PCs through hardware support for stereo and Dolby R ©Surround Sound versions 4.1, 5.1, and 7.1. However, these solutions provide sound panning only in a planar configuration, typically around the user’s entertainment room. The drivers for these home-market cards (e.g. Direct Sound) do not have support for non-planar configurations. There are other cards and drivers available that provide true 3D spatial audio, but they are geared for the professional user market and have steep price tags over one thousand dollars. We explain how to use inexpensive consumer-level hardware and free software for Linux to build a true 3D spatial audio system.

A Morphological Analysis of Audio-Objects and their Control Methods for 3D Audio
Recent technological improvements in audio reproduction systems increased the possibilities to spatialize sources in a listening environment. The spatialization of reproduced audio is highly dependent on the recording technique, the rendering method, and the loudspeaker configuration. While object-based audio production reduces this dependency on loudspeaker configurations, related authoring to...

SMART-I is a high quality 3D audio-visual interactive rendering system. In SMART-I, the screen is also used as a multichannel loudspeaker. The spatial audio rendering is based on Wave Field Synthesis, an approach that creates a coherent spatial perception of a spatial sound scene over a large listening area. The azimuth localization accuracy of the system has been verified by a perceptual exper...

When it comes to 3D Virtual Environments it is well known that 3D sound is of great importance to the whole interactive experience. The percept of sound is a major counterpart for the eyesight, since it describes the location, the momentum and the attitude towards the listener, of each surrounding entity. The sound can offer precision of spatial perception that cannot be achieved by the eye its...
متن کاملA VR Interface for Collaborative 3D Audio Performance
This paper presents a novel interaction paradigm to support musical performance using spatial audio. This method reduces the interface bottleneck between artistic intent and spatial sound rendering and allows dynamic positioning of sounds in space. The system supports collaborative performance, allowing multiple artists to simultaneously control the audio spatialization. The interface prototype...
متن کاملDeveloping a BIM-based Spatial Ontology for Semantic Querying of 3D Property Information
With the growing dominance of complex and multi-level urban structures, current cadastral systems, which are often developed based on 2D representations, are not capable of providing unambiguous spatial information about urban properties. Therefore, the concept of 3D cadastre is proposed to support 3D digital representation of land and properties and facilitate the communication of legal owners...
