The first HRTF defines first audio feature values distributed at first intersection nodes in a spherical coordinate system over audio frequencies. The first intersection nodes are arranged with a first spatial resolution in the spherical coordinate system. The first HRTF is upsampled into the second HRTF by a spherical convolutional neural network model. The second HRTF defines a plurality of second audio feature values distributed at second intersection nodes in the spherical coordinate system over the audio frequencies. The second intersection nodes in the second HRTF are arranged with a second spatial resolution higher than the first spatial resolution of the first intersection nodes in the first HRTF."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Audio processing method and electronic apparatus","description":"An audio processing method is configured to upsample a first head related transfer function (HRTF) into a second HRTF.
