Upmix B-Format Ambisonic Room Impulse Responses Using a Generative Model

Applied Sciences, 2023
Ambisonic room impulse responses (ARIRs) are recorded to capture the spatial acoustic characteristics of specific rooms, with widespread applications in virtual and augmented reality.

Perceptual evaluation of approaches for binaural reproduction of non-spherical microphone array signals

Frontiers in Signal Processing, 2022
Microphone arrays consisting of sensors mounted on the surface of a rigid, spherical scatterer are popular tools for the capture and binaural reproduction of spatial sound scenes.

Do near-field cues enhance the plausibility of non-individual binaural rendering in a dynamic multimodal virtual acoustic scene?

Acta Acustica, 2021
It is commonly believed that near-field head-related transfer functions (HRTFs) provide perceptual benefits over far-field HRTFs that enhance the plausibility of binaural rendering of nearby sound sources.

On the influence of non-individual binaural cues and the impact of level normalization on auditory distance estimation of nearby sound sources

Acta Acustica, 2021
Nearby sound sources provide distinct binaural cues, mainly in the form of interaural level differences, which vary with respect to distance and azimuth. However, there is a long-standing controversy regarding whether humans can actually utilize binaural

Assessing HRTF preprocessing methods for Ambisonics rendering through perceptual models

Acta Acustica, 2022
Binaural rendering of Ambisonics signals is a common way to reproduce spatial audio content. Processing Ambisonics signals at low spatial orders is desirable in order to reduce complexity, although it may degrade the perceived quality, in part due to the

Dynamic Binaural Rendering: The Advantage of Virtual Artificial Heads over Conventional Ones for Localization with Speech Signals

Applied Sciences, 2021
As an alternative to conventional artificial heads, a virtual artificial head (VAH), i.e., a microphone array-based filter-and-sum beamformer, can be used to create binaural renderings of spatial sound fields. In contrast to conventional artificial heads,

Binaural Rendering with Measured Room Responses: First-Order Ambisonic Microphone vs. Dummy Head

Applied Sciences, 2020
To improve the limited degree of immersion of static binaural rendering for headphones, an increased measurement effort to obtain multiple-orientation binaural room impulse responses (MOBRIRs) is reasonable and enables dynamic variable-orientation ...
