Embodiment approach

[0116] Please refer to figure 2 , which shows a flow chart of a method for processing an audio signal provided in an exemplary embodiment of the present application, the method is applied to a terminal with an audio signal processing function, and the method is figure 1 An optional implementation of step 102 in the embodiment, the method includes:

[0117] Step 201: Input the first stereo audio signal into a high-pass filter for filtering to obtain a first high-frequency signal.

[0118] The terminal filters the first stereo audio signal into the high-pass filter to obtain a first high-frequency signal, where the first high-frequency signal is a superposition signal of the first left-channel high-frequency signal and the first right-channel high-frequency signal.

[0119] Optionally, the terminal filters the first stereo sound through a 4th-order IIR high-pass filter to obtain the first high-frequency signal.

[0120] Step 202, according to the first high-frequency signal, ...

Abstract

The invention discloses an audio signal processing method and apparatus, and a terminal, and belongs to the technical field of audio processing. The method comprises the following steps: obtaining a first stereo audio signal; splitting the first stereo audio signal into 5.1 channel audio signals; performing signal processing on the 5.1 channel audio signals according to sound box parameters of a three-dimensional surrounding 5.1 virtual sound box to obtain processed 5.1 channel audio signals; and synthesizing the processed 5.1 channel audio signals into a second stereo audio signal. Accordingto the audio signal processing method and apparatus disclosed by the invention, by splitting the first stereo audio signal into the 5.1 channel audio signals, processing and synthesizing the 5.1 channel audio signals into the second stereo audio signal, and playing the second stereo audio signal via a double-channel audio playing unit, so that a user obtains a stereo effect of 5.1 channel audio, the problem of relatively poor stereoscopic effect because only the two-channel audio signals are played in related art is solved, and the stereo effect of audio playing is improved.

Description

technical field [0001] The present application relates to the technical field of audio processing, and in particular to an audio signal processing method, device and terminal. Background technique [0002] In related technologies, an audio playback device plays a binaural audio signal through an audio playback unit such as a binaural earphone or a loudspeaker so that a user can obtain a stereo effect. Wherein, the two-channel audio signal is an audio signal superimposed by the left channel audio signal and the right channel audio signal, the left channel part of the audio playback unit plays the left channel audio signal, and the right channel part of the audio playback unit plays the right sound channel audio signal, the user obtains a three-dimensional sense of hearing through the phase difference between the left channel audio signal played by the left channel part and the right channel audio signal played by the right channel part. [0003] In the related art, the audio...
