Low Frequency Simulations for Ambisonics Auralization of a Car Sound System
2021 Immersive and 3D Audio: from Architecture to Automotive (I3DA), 2021In this paper, a technique is described for obtaining the High Order Ambisonics (HOA) Impulse Responses (IRs) of an automotive infotainment system, relying on Finite Elements Method (FEM) simulations performed in COMSOL Multiphysics.

Abstract In ambisonics, the number of loudspeakers must be greater than or equal to the requirement of the ambisonic order. On the one hand, if the number of loudspeakers in an ambisonic system satisfies the minimum requirement exactly, localization in the lateral regions can be poor. On the other hand, the use of a large number of loudspeakers in an

IEEE International Conference on Acoustics, Speech, and Signal Processing
Estimating frequency-varying acoustic parameters is essential for enhancing immersive perception in realistic spatial audio creation. In this paper, we propose a unified framework that blindly estimates reverberation time (T60), direct-to-reverberant ...

Ambisonic reproduction of sound
Electronics and Power, 1973Earlier this year, the correspondence columns of Electronics & Power were filled with letters arguing the pros and cons of quadraphonics. One correspondent put forward the view that ambisonic reproduction had decided advantages over quadraphonic reproduction. In this article, Prof. Fellgett expands his views.

Ultra-Low Delay Lossless Compression of Higher Order Ambisonics
IEEE International Conference on Acoustics, Speech, and Signal ProcessingCoding delay has emerged as a significant obstacle to wider adoption of Higher Order Ambisonics (HOA), a promising flexible format employed in representation and coding of spatial audio. Low delay is critical in many applications, such as virtual reality,

Direction and Reverberation Preserving Noise Reduction of Ambisonics Signals
IEEE/ACM Transactions on Audio Speech and Language Processing, 2020Ambisonics encodes the directional information of a sound field w.r.t. a reference position in an efficient and scalable way. However, the sound field might contain undesired noise.

Mapping a room impulse response (RIR) to its Ambisonics representation is not always feasible. However, by adding a weak assumption (i.e., the existence of at least two perpendicular walls in the environment), the Ambisonics representation is restricted ...

Fundamentals of a Parametric Method for Virtual Navigation Within an Array of Ambisonics Microphones
, 2020Fundamental aspects of a method for virtual navigation of a sound field within an array of ambisonics microphones, wherein the subset of microphones to be used for interpolation is determined parametrically, are presented.

Translation of a Higher Order Ambisonics Sound Scene Based on Parametric Decomposition
IEEE International Conference on Acoustics, Speech, and Signal Processing, 2020This paper presents a novel 3DoF+ system that allows to navigate, i.e., change position, in scene-based spatial audio content beyond the sweet spot of a Higher Order Ambisonics recording.
