Embodiment approach

[0074] 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:

[0075] Step 201: Input the first stereo audio signal into a high-pass filter for filtering to obtain a first high-frequency signal.

[0076] 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.

[0077] Optionally, the terminal filters the first stereo sound through a 4th-order IIR high-pass filter to obtain the first high-frequency signal.

[0078] Step 202, according to the first high-frequency signal, ...

Abstract

The application discloses a processing method and device of an audio signal, and a terminal, and belongs to the field of the audio processing. The method comprises the following steps: acquiring 5.1 sound track audio signal; acquiring HRTF data corresponding to each virtual soundbox in the 5.1 virtual soundbox according to the coordinate of the 5.1 virtual soundbox in the virtual environment; processing the corresponding sound track audio signal in the 5.1 sound track audio signal according to the HRTF data corresponding to each virtual soundbox, thereby obtaining the processed 5.1 sound trackaudio signal; and synthesizing the processed 5.1 sound track audio signal as the stereo sound audio signal. After processing the 5.1 sound track audio signal according to the HRTF data of each 5.1 virtual soundbox, the processed sound track audio signal is synthesized to obtain the stereo sound audio signal, and a user can play the 5.1 sound track audio signal only through a normal earphone or soundbox, and the good playing tone can be acquired.

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] 5.1 channels include: front left channel, front right channel, front center channel, rear left channel, rear right channel, a total of 5 channels, and 0.1 channel. 0.1 channel is also called low-frequency channel or subwoofer channel. [0003] Many movies use 5.1-channel audio signals for audio recording and playback. In the related technology, the user needs to purchase a speaker device supporting 5.1 channels, input the 5.1 channel audio signal to the audio playback device and the power amplifier device, and then the power amplifier device outputs the audio signals of each channel to the 5.1 channel speaker respectively device to play. [0004] However, when the user does not have a speaker device supporting 5.1 channels, the 5.1 channel audio signal cannot be played....
