Abstract: An audio processing method is configured to upsample a first head related transfer function (HRTF) into a second HRTF. 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.

Abstract: A computer adapter such as a TV card includes a circuit board to be inserted in an expansion slot of the computer system; a signal transmission connector socket having a first end secured to the circuit board and a second end to be coupled to an external signal transmission connector; a securing plate securable to the computer system and the circuit board, and having a through hole for exposing the second end of the signal transmission connector socket; and an elastic metallic conductive member mounted between the signal transmission connector socket and the securing plate. The elastic metallic conductive member has a crooked cross-section in a certain direction so as to be elastically stretchable in the certain direction, thereby in contact with both of the signal transmission connector socket and the securing plate to accomplish electric connection.
