Embodiment 1

[0042] see figure 2 , shows a schematic workflow diagram of the audio processing method provided by the present invention.

[0043] The audio processing method comprises the steps of:

[0044] In step S201, the original audio is obtained.

[0045] It can be understood that: the step of obtaining the original audio includes receiving a user's selection instruction, and reading the selected original audio from an audio storage (such as a music library).

[0046] In step S202, the playing type is obtained, and the original audio is preliminarily adjusted according to its corresponding type parameter.

[0047] It can be understood that obtaining the playback type can be used as an auxiliary step for preliminary adjustment, so that the preliminary adjusted original audio can be equalized in a subsequent step, or this step can be ignored by selecting a custom type.

[0048] Specifically, it includes the following steps:

[0049] (1) Obtain the playback type and generate preset ...

Embodiment 2

[0080] see image 3 , which is a block diagram of the audio processing system provided by the present invention.

[0081] The audio processing system 30 includes: an acquisition module 31 , a type module 32 , a receiving module 33 , an equalization module 34 , an output module 35 , and a mapping information generation module 36 .

[0082] Specifically, the functions of the above modules can be combined image 3 and Figure 4 Be explained. in, Figure 4 The audio processing system 30' is shown as image 3 A detailed schematic diagram of the modules of the audio processing system 30 . Understandably, Figure 4 as a pair image 3 as an example of elaboration and not as a reference to image 3 The limitations of the implementations and the realization of the same effect in a similar manner are all within the spirit of the present invention.

[0083] An acquisition module 31, configured to acquire original audio.

[0084] It can be understood that: the acquisition module ...

Embodiment 3

[0108] see Figure 5 , which is a schematic timing diagram of the audio processing method and the audio processing system provided by the embodiment of the present invention. This embodiment is mainly used to demonstrate the equalization process of the present invention. The audio processing system mainly includes: an acquisition module, a reception module, an equalization module, and an output module.

[0109] In step A, the mapping information generation module automatically generates mapping information during installation, and sends the mapping information to the equalization module.

[0110] The generating process includes: obtaining the number M of built-in frequency bands; and mapping the built-in M frequency bands to the low frequency range, the middle frequency range, and the high frequency range to form the preset mapping information. In this embodiment, the M is taken as an example of 10 common frequency bands.

[0111] Wherein, the preset mapping information inc...

Abstract

The invention provides an audio processing method and an audio processing system. The audio processing method comprises the following steps: obtaining original audio; receiving adjustment parameters from a low audio frequency band, an intermediate audio frequency band and/or a high audio frequency band; according to the adjustment parameters and preset mapping information, scheduling M built-in frequency bands, and carrying out equalization processing in real time on the original audio, wherein the preset mapping information comprises a mapping relation set between the high audio frequency band and the M built-in frequency bands, a mapping relation set between the intermediate audio frequency band and the M built-in frequency bands, and a mapping relation set between low audio frequency band and the M built-in frequency bands; and outputting the audio subjected to the equalization processing. According to the invention, through obtaining the adjustment parameters from low, intermediate and high audio frequency bands and the preset mapping information, audio processing on multiple built-in frequency bands is realized, the operation is simple, and it is ensured that the audio processing is fine and smooth.

Description

technical field [0001] The invention belongs to the field of audio processing, in particular to an audio processing method and an audio processing system. Background technique [0002] The function of the equalizer (EQ, equaliser) is to adjust the gain value of the signal in each frequency band. By modifying the overtone level of each frequency in the sound, it is optimized for a certain type of music and enhances people's feelings. Common ones include: Normal, Rock, Pop, Dance, Classical, Soft, Jazz, Metal, Bass, and Custom. Customization is self-adjustment, there is no fixed mode applied, and the real EQ according to personal preference can satisfy different personal listening preferences. [0003] EQ usually includes the following parameters: F (Frequency, frequency) - this is the parameter used to set the frequency point you want to adjust; G (Gain, gain) - used to adjust the F value you set Gain or attenuation parameters; Q (Quantize, digital conversion) - used to set...
