DBAP - Distance-Based Amplitude Panning
Most common techniques for spatialization require the listener to be positioned at a “sweet spot” surrounded by loudspeakers. For practical concert, stage, and installation applications such layouts may not be desirable. Distance-based amplitude panning (DBAP) offers an alternative panningbased spatialization method where no assumptions are made concerning the layout of the speaker array nor th...
متن کاملHigh order Ambisonic decoding method for irregular loudspeaker arrays
Ambisonics, a sound field synthesis and reproduction technique, has shown promising results in conveying three-dimensional spatialized sound. Ambisonic encodings directly describe the spatial properties of sound fields without reference to the reproduction system. Precise regeneration of a sound field requires a large number of loudspeakers arranged so as to adequately sample all directions; th...
متن کاملUsing Vbap-derived Panning Functions for 3d Ambisonics Decoding
In this contribution we will explain the derivation of panning functions from the vector base amplitude panning (VBAP) technology for 3-dimensional Ambisonics decoding. VBAP turned out to be a robust method for presenting virtual acoustic sources. Each virtual source to be played back using VBAP has to be described by a monophonic signal and a 3-dimensional position as parameter. In opposite to...
متن کاملEvaluation of Distance Based Amplitude panning for spatial audio
Distance-Based Amplitude Panning (DBAP) has recently been proposed as a new technique for panning sound sources in two and three dimensional spaces spaces. In this paper, DBAP is compared with two established alternatives, Ambisonics and Vector-Based Amplitude Panning, both objectively in terms of speaker gains and their variation with source position, and subjectively using listening tests to ...
متن کاملSparse, `1-Optimal Multi-Loudspeaker Panning and its Relation to Vector Base Amplitude Panning
Panning techniques, such as vector base amplitude panning (VBAP) are a widely-used practical approach for spatial sound reproduction using multiple loudspeakers. Although limited to a relatively small listening area, they are very efficient and offer good localisation accuracy, timbral quality as well as a graceful degradation of quality outside the sweet spot. The aim of this paper is to inves...
