New Neural Operator SPARO Enhances HRTF Upsampling and Personalization

By PulseAugur Editorial · [1 sources] ·

Researchers have developed SPARO, a novel neural operator designed to improve head-related transfer function (HRTF) upsampling and personalization from sparse audio measurements. This method formulates HRTF upsampling as an operator learning problem, projecting sparse measurements onto learned spherical latent modes processed by Transformer blocks. SPARO demonstrated superior performance on the SONICOM dataset, achieving lower log-spectral distortion and interaural level difference errors compared to existing baselines, while also significantly outperforming neural-field methods in reconstruction speed.
