  • Patent number: 11863952
    Abstract: Audio signals from microphones of a mobile device are received. Each audio signal is generated by a respective microphone of the microphones. First microphones are selected from among the microphones to generate a front audio signal. Second microphones are selected from among the microphones to generate a back audio signal. A first audio signal portion, which is determined based at least in part on the back audio signal, is removed from the front audio signal to generate a modified front audio signal. A second audio signal portion is removed from the modified front audio signal to generate a left-front audio signal. A third audio signal portion is removed from the modified front audio signal to generate a right-front audio signal.

  • Publication number: 20230359430
    Abstract: Media input audio data corresponding to a media stream and microphone input audio data from at least one microphone may be received. A first level of at least one of a plurality of frequency bands of the media input audio data, as well as a second level of at least one of a plurality of frequency bands of the microphone input audio data, may be determined.

  • Publication number: 20230171337
    Abstract: In this application, by using a method for collaborative recording by using a mobile terminal and the true wireless stereo earbud, recording with more complete data amount can be collected, and cooperative noise reduction is performed on a recording signal collected by the mobile terminal and a recording signal collected by the true wireless stereo earbud, so that accuracy and integrity of a human voice signal obtained through separation are higher. Further, in this application, when the true wireless stereo earbud performs recoding in a mode of single-earbud recording, a data amount of the true wireless stereo earbud is relatively small. Therefore, when the mobile terminal receives, through Bluetooth, data sent by the true wireless stereo earbud, excessive occupation of Bluetooth bandwidth of the mobile terminal is avoided, and power consumption of a mobile phone is reduced.

  • Patent number: 11640830
    Abstract: Microphone signals are received from microphones of a computer device. Each microphone signal of the microphone signals is acquired by a respective microphone of the microphones. A previously unselected microphone is selected from the microphones as a reference microphone, which generates a reference microphone signal. An adaptive filter is used to create, based on microphone signals of the microphones other than the reference microphone, predicted microphone signals for the reference microphone. Based on the predicted microphone signals for the reference microphone, an enhanced microphone signal is outputted for the reference microphone. The enhanced microphone signal may be used as microphone signal for the reference microphone in subsequent audio processing operations.
