Problems solved by technology

[0004] In the prior art, when audio processing is performed, various audio data are processed by a DSP processor in a preset manner. When multi-channel audio processing is performed, DSP cannot realize parallel processing, and the processing efficiency is low. All kinds of audio data are processed by a DSP processor according to the preset method, but in fact, different types of audio data have their own characteristics, and the same processing method is adopted for all audio, so that the effect of the processed audio data is not ideal

Embodiment 1

[0024] Embodiment 1. An audio processing method, the flow chart of which is as follows figure 1 shown, including:

[0025] A1, receiving audio data;

[0026] In the embodiment of the present invention, receiving audio data may be received through a System On Chip (System On Chip, SOC) system bus, such as an Advanced High-performance Bus (Advanced High-performance Bus, AHB).

[0027] A2, select an audio processing channel; the audio processing channel includes a preset number of audio processing units.

[0028] In the embodiment of the present invention, several audio processing channels are preset for processing received audio data, and the multiple audio processing channels may be the same, that is, realize the same function, or different, that is, realize different functions. There are many ways to select an audio processing channel, such as selecting randomly, selecting according to the load situation, and in some implementations, selecting according to the type of audio ...

Embodiment 2

[0034] Embodiment 2, an audio processing method, the flow chart is as follows figure 2 shown, including:

[0035] B1, receiving audio data;

[0036] B2, selecting an audio processing channel according to the type of the audio data; the audio processing channel includes a preset number of audio processing units;

[0037] In the embodiment of the present invention, for different types of audio data, a differentiated processing method is adopted. Specifically, a number of audio processing channels are preset, and each audio processing channel contains a preset number of audio processing units. A processing unit is a device that can perform certain audio processing functions, such as filtering unit, resampling unit, gain adjustment unit, etc.

[0038] The following example illustrates:

[0039] For the received audio data, first determine the type of audio data, which can be classified in many ways, for example: audio signal input from a microphone, voice signal from a communi...

Embodiment 3

[0052] Embodiment 3, an audio processing device, the structural diagram is as follows image 3 As shown, it includes: receiving unit 310, arbitration unit 320, and audio processing channel 1 to audio processing channel N (N belongs to an integer, N>1)

[0053] a receiving unit 310, configured to receive audio data;

[0054] An arbitration unit 320, configured to select an audio processing channel X for the audio data received by the receiving unit 310 according to the type of the audio data, where X belongs to [1, N];

[0055] In the embodiment of the present invention, the arbitration unit 320 selects an audio processing channel, which can be selected according to the type of audio data received by the receiving unit 310, so as to realize differentiated processing of different types of audio data; Priority assigns audio processing channels to audio data.

[0056] The audio processing channel includes a preset number of audio processing units, and the audio processing units ...

Abstract

The invention discloses an audio treatment method and an audio treating device. In one embodiment of the invention, when audio data is received, an audio treating passage is selected fro the audio data based on the type of the audio data; the audio processing passage comprises preset number of audio processing units; the preset number of audio processing units of the audio treating passage carry out resampling treatment and gain adjustment treatment for implementing audio treatment, because of a plurality of audio processing passages are provided, parallel treatment to a plurality of audio data is implemented, audio treating efficiency is raised, and simultaneously a plurality of audio treating passages are interdependent, thereby enhancing anti-fault capability of the system, further more, audio effect after treating is good because of the a plurality of treating passages treats audio data of distinct types distinctively.

Description

technical field [0001] The invention relates to the technical field of audio processing, in particular to an audio processing method and an audio processing device. Background technique [0002] In a media music playback device, a very important job is to process the audio source signal, so as to obtain a better auditory effect. Commonly used processing techniques include resampling, gain adjustment, sound mixing, and sound effect processing. [0003] In the prior art, audio processing is generally performed by a digital signal processor (Digital Signal Processor, DSP). When performing audio processing, the DSP obtains audio source data from the system memory, performs corresponding processing through the pre-installed audio processing software, and then writes it back to the system memory. [0004] In the prior art, when audio processing is performed, various audio data are processed by a DSP processor in a preset manner. When multi-channel audio processing is performed, ...
