Assignee: HUAWEI TECHNOLOGIES CO., LTD.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H | IPC H

Claim 11:
12. The apparatus according to claim 11, wherein the programming instructions when executed further cause the audio signal processing apparatus to:
multiply a first modification factor with a first high-band impulse response corresponding to the third HRTF to obtain a first target HRTF, wherein the first modification factor is greater than 0 and less than 1;
or
multiply a first modification factor with a first high-band impulse response corresponding to the third HRTF to obtain a first temporal HRTF, wherein the first modification factor is greater than 0 and less than 1; and
multiply a third modification factor with each impulse response corresponding to the first temporal HRTF to obtain a first target HRTF, wherein the third modification factor is greater than 1;
or
multiply a first modification factor with a first high-band impulse response corresponding to the third HRTF to obtain a first temporal HRTF, wherein the first modification factor is greater than 0 and less than 1; and
multiply a first value with each impulse response corresponding to the first temporal HRTF to obtain a first target HRTF, wherein the first value is a ratio of a first sum of squares to a second sum of squares, the first sum of squares is a sum of squares of all impulse responses corresponding to the third HRTF, and the second sum of squares is a sum of squares of all impulse responses corresponding to the first temporal HRTF.
