Nearfield binaural synthesis and ambisonics.

چکیده
Ambisonic encodings can be rendered binaurally, as well as for speaker arrays. This process is developed for general high-order Ambisonic encodings of soundfields containing near as well as far sources. For sufficently near sources an error is identified, resulting from the limited field of validity of the freefield harmonic expansion. A modified expansion is derived that can render such sources correctly.

Nearfield Synthesis of Complex Sources with High-order Ambisonics, and Binaural Rendering
A scheme is presented for encoding general complex sources in high-order Ambisonic soundfields, with control over position and orientation. Also reviewed is related work by the author on the binaural rendering of nearfield sources, accounting fully for the physical constraints of this problem. Together these developments provide a means for creating high quality nearfield auditory displays over...
متن کاملSound Field Synthesis Toolbox
An open source toolbox for Sound Field Synthesis (SFS) is introduced. The toolbox is able to numerically simulate sound fields synthesized by SFS methods like Wave Field Synthesis or higher order Ambisonics. Various loudspeaker driving signals for the mentioned methods are provided for 2-, 2.5and 3-dimensional synthesis. The toolbox allows mono-frequent as well as broadband excitation signals. ...
متن کاملEvaluation of sound field synthesis techniques with a binaural auditory model
Wave field synthesis and Ambisonics strive to reconstruct a sound field within a listening area using the interference of loudspeaker signals. Due to the spatial sampling, an error-free reconstruction is not achieved within the entire listening area and consequently, the perceived quality of the reproduction may be impaired. Specifically, sound events may be localized incorrectly and the indivi...
متن کاملAnalysis on the Timbre of Ambisonics Repro- Dution Using a Binaural Loudness Model
Ambisonics are a series of flexible sound reproduction systems that decompose and reconstruct sound field by each order approximation of horizontal Fourier or spatial spherical harmonics decomposition. For a given order reproduction, providing that the product of wave number and the radius of the rendering region is approximately less than the order, the system is able to recreate the target so...
متن کاملAnalysis on the timbre of Ambisonics recording by circular and spherical microphone array using a binaural loudness model
Ambisonics are a series of flexible sound reproduction systems that decompose and reconstruct sound field by each order approximation of spatial harmonics decomposition. Circular or spherical microphone array has been used for Ambisonics recording. For an array with given radius as well as given number and configuration of microphones, the spatial harmonics signals up to certain temporal freque...
