  • Patent number: 10827293
    Abstract: 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.

  • Patent number: 10681486
    Abstract: 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.

  • Patent number: 10595122
    Abstract: The disclosure provides an audio processing device, an audio processing method for controlling a plurality of speakers, and a computer program product. The audio processing device includes a memory, a transceiver, and a processor. The memory stores a plurality of modules. The transceiver is wirelessly paired with a plurality of speakers. The processor executes the modules to perform following steps: requesting each of the speakers to output an audio positioning signal; collecting the audio positioning signal from each of the speakers; retrieving a location of each of the speakers relative to the audio processing device according to the audio positioning signal from each of the speakers; adjusting a plurality of audio contents based on the location of each of the speakers relative to the audio processing device; and sending the audio contents to the speakers to control the speakers outputting the audio contents.

  • Patent number: 10382878
    Abstract: 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.

  • Patent number: 10257633
    Abstract: A sound-reproducing method that includes the steps outlined below is provided. A playback sound is generated by applying original audio into a test environment. The playback sound is received to generate received sound data. At least one test environment spatial parameter corresponding to the test environment is calculated according to known audio data related to the original audio and the received sound data. Input audio is modified by applying the test environment spatial parameter thereto to generate reproduced audio.
