  • Patent number: 12363481
    Abstract: The present application provides an audio processing method and apparatus, a wireless earphone, and a storage medium. A first wireless earphone receives a first to-be-presented audio signal sent by a playing device, and a second wireless earphone receives a second to-be-presented audio signal sent by the playing device; then, the first wireless earphone performs rendering processing on the first to-be-presented audio signal to obtain a first audio playing signal, and the second wireless earphone performs rendering processing on the second to-be-presented audio signal to obtain a second audio playing signal; and finally the first wireless earphone plays the first audio playing signal, and the second wireless earphone plays the second audio playing signal. Therefore, it is possible to achieve technical effects of greatly reducing the delay and improving the sound quality of the earphone since the wireless earphone can render the audio signals independently of the playing device.

  • Publication number: 20230156403
    Abstract: Provided are an audio processing method, apparatus, system and a storage medium. Firstly, a wireless earphone receives a to-be-presented audio signal sent by a playback device in a wireless transmission mode. The to-be-presented audio signal includes an audio signal that has undergone rendering processing performed the playback device, namely a first audio signal, and includes an audio signal that is to be rendered, namely a second audio signal. Then, if the to-be-presented audio signal includes the second audio signal, the wireless earphone performs rendering processing on the second audio signal, to obtain a third audio signal. Finally, the wireless earphone performs subsequent audio playing, according to the first audio signal and/or the third audio signal.

  • Publication number: 20070067166
    Abstract: The present invention provides a method and device of multi-resolution vector quantization (VQ) for audio encoding and decoding used to analyze the audio signal in multi-resolution and quantize the vectors of them. Said method for encoding audio comprises the steps of: adaptively filtering a input audio signal so as to gain a time-frequency filter coefficient and output a filtered signal; dividing vectors of the filtered signal in a time-frequency plane so as to gain a vector combination; selecting the vector to be quantized; quantizing the selected vectors and calculating a quantization residual error; and transmitting a quantized coding task information as a side-information of an encoder to an audio decoder to quantize and encode the quantization residual error. The invention can adaptively filter the audio signal, and adjust the resolutions of time and frequency.
