Abstract: Binaural Ambisonic rendering is widely used in immersive applications such as virtual reality due to its sound field rotation capabilities. An issue of low-order Ambisonics is that interaural level differences (ILDs), a crucial cue for horizontal localisation, are often reproduced lower than they should be, which reduces lateralisation. This paper introduces a simple method for Ambisonic ILD Optimisation (AIO), aiming to bring the ILDs produced by binaural Ambisonic rendering closer to those of head-related impulse responses (HRIRs). AIO is evaluated using first-order Ambisonics versus a reference dataset of HRIRs for all locations on the sphere using estimated ILD, perceptual spectral difference and horizontal plane localisation. Results show an overall improvement in all tested metrics.

AB - Binaural Ambisonic rendering is widely used in immersive applications such as virtual reality due to its sound field rotation capabilities. An issue of low-order Ambisonics is that interaural level differences (ILDs), a crucial cue for horizontal localisation, are often reproduced lower than they should be, which reduces lateralisation. This paper introduces a simple method for Ambisonic ILD Optimisation (AIO), aiming to bring the ILDs produced by binaural Ambisonic rendering closer to those of head-related impulse responses (HRIRs). AIO is evaluated using first-order Ambisonics versus a reference dataset of HRIRs for all locations on the sphere using estimated ILD, perceptual spectral difference and horizontal plane localisation. Results show an overall improvement in all tested metrics.
