  • Publication number: 20220164159
    Abstract: A method for playing audio, applicable to a terminal and including: displaying a virtual scene acquired based on a real scene; acquiring a corresponding position of the terminal in the virtual scene by mapping a position of the terminal in the real scene to the virtual scene; adjusting a volume parameter of at least one virtual sound box based on a relative positional relationship between the at least one virtual sound box and the terminal in the virtual scene; and playing audio based on the volume parameter of the at least one virtual sound box.

  • Patent number: 11315582
    Abstract: A method for recovering audio signals, a terminal and a storage medium are provided. The method includes: buffering an audio signal sampled at a preset number of sampling points each time, and then performing frequency spectrum analysis on the sampled audio signal by FFT; when it is determined that the audio signal is compressed, filtering a frequency point; recovering high-frequency signals based on audio signals before the frequency point; and performing phase recovery on the high-frequency signals. Thus, compressed high-frequency signals in the audio signals may be recovered.

  • Patent number: 11272304
    Abstract: The present disclosure provides a method for playing audio data, and belongs to the field of computer technology. The method includes: in a process of playing audio, partitioning left-channel audio data of the audio into audio data of a preset number of frequency sub-bands and partitioning right-channel audio data of the audio into audio data of the preset number of frequency sub-bands; calibrating the left-channel audio data of respective frequency sub-bands with left-channel calibration parameter values of respective frequency sub-bands to obtain left-channel audio data to be played; calibrating the right-channel audio data of respective frequency sub-bands with right-channel calibration parameter values of respective frequency sub-bands to obtain right-channel audio data to be played; and playing, over a left channel, the left-channel audio data to be played, and playing, over a right channel, the right-channel audio data to be played.

  • Patent number: 11039261
    Abstract: An audio signal processing method. The audio signal processing method includes: acquiring a first stereo audio signal; splitting the first stereo audio signal into 5.1-channel audio signals; obtaining processed 5.1-channel audio signals by processing the 5.1-channel audio signals based on a speaker box parameter of a three-dimensional surround 5.1-channel virtual speaker box; and synthesizing the processed 5.1-channel audio signals into a second stereo audio signal.

  • Publication number: 20200112812
    Abstract: The present disclosure discloses an audio signal processing method and device, a terminal and a storage medium and belongs to the field of audio processing technology. The audio signal processing method includes: acquiring a first stereo audio signal; splitting the first stereo audio signal into 5.1-channel audio signals; processing the 5.1-channel audio signals based on a speaker box parameter of a three-dimensional surround 5.1-channel virtual speaker box to obtain processed 5.1-channel audio signals; and synthesizing the processed 5.1-channel audio signals into a second stereo audio signal. Since the first stereo audio signal is split into the 5.1-channel audio signals, the 5.1-channel audio signals are processed and synthesized into the second stereo audio signal, and the second stereo audio signal is played by a double-channel audio playback unit, a user may enjoy a 5.1-channel audio stereo effect.
