Patent number: 10827293Abstract: A sound reproducing method used in sound reproducing apparatus that includes the steps outlined below is provided. A sound signal is generated with a 3D sound generating process according to listener data and sound data. Pre-recorded sound data is retrieved to further generate a target distance function corresponding to the sound distance. A fixed head-related transfer function corresponding to a fixed distance is retrieved. A target head-related transfer function corresponding to the sound distance is generated by adapting the target distance function to the fixed head-related transfer function. The sound signal is reproduced by multiplying the sound signal by the target head-related transfer function.Type: GrantFiled: October 15, 2018Date of Patent: November 3, 2020Assignee: HTC CorporationInventors: Chun-Min Liao, Yan-Min Kuo, Li-Yen Lin, Chi-Tang Ho, Tien-Ming Wang, Tsung-Yu Tsai, Yen-Chieh Wang, Shuo-Yen Lin

Patent number: 10681486Abstract: A method for obtaining Hi-Res audio transfer information is provided. The method is applicable to the electronic device having a processor. In the method, a first audio signal is captured and converted from the time domain into in the frequency domain to generate a first signal spectrum. Then, a regression analysis is performed on an energy distribution of the first signal spectrum to predict an extended energy distribution according to the first signal spectrum, and head-related parameters are used to compensate for the extended energy distribution to generate an extended signal spectrum. Finally, the first signal spectrum and the extended signal spectrum are combined into a second signal spectrum which is converted from the frequency domain into the time domain to generate a second audio signal including Hi-Res audio transfer information.Type: GrantFiled: October 18, 2018Date of Patent: June 9, 2020Assignee: HTC CorporationInventors: Tien-Ming Wang, Li-Yen Lin, Chun-Min Liao, Chi-Tang Ho, Yan-Min Kuo, Tsung-Yu Tsai

Patent number: 10382878Abstract: A sound reproducing method used in sound reproducing apparatus that includes the steps outlined below is provided. A sound signal with a three-dimensional (3D) sound generating process is generated according to listener data and sound data. Whether a sound source position is within a target region relative to a listener position within a virtual environment is determined according to the listener data and the sound data. The sound signal is multiplied by an adjusting function to enhance peaks and valleys of the sound signal while maintaining a behavior of the sound signal when the sound source position is within the target region. The sound signal is reproduced.Type: GrantFiled: October 17, 2018Date of Patent: August 13, 2019Assignee: HTC CorporationInventors: Yan-Min Kuo, Chun-Min Liao, Li-Yen Lin, Chi-Tang Ho, Tien-Ming Wang, Tsung-Yu Tsai
