Abstract: A method for improving sound quality of a speaker includes: performing frequency division on an input signal of the speaker to obtain a first low-frequency input signal and a first high-frequency input signal, where the input signal is a time domain signal; performing transient detection on the first low-frequency input signal to determine whether the first low-frequency input signal is a transient signal; if the first low-frequency input signal is a transient signal, performing signal envelope modulation on the first low-frequency input signal to obtain a second low-frequency input signal; determining an output signal of the speaker based on the second low-frequency input signal and the first high-frequency input signal, where a startup voltage of the second low-frequency input signal is higher than a startup voltage of the first low-frequency input signal, and loudness of the second low-frequency input signal is greater than loudness of the first low-frequency input signal.

Abstract: Embodiments of this application provide an audio processing method and system, and an electronic device. The method includes: in response to a play operation of a user, performing spatial audio processing on an initial audio clip in a source audio signal to obtain an initial binaural signal, and playing the initial binaural signal; receiving a setting of the user for a rendering effect option, where the rendering effect option includes at least one of the following: a sound image position option, a distance perception option, or a spatial perception option; and performing spatial audio processing on an audio clip subsequent to the initial audio clip in the source audio signal based on the setting, to obtain a target binaural signal.
