Embodiment
Embodiment below in conjunction with concrete does further explain to the utility model.
A kind of four-way audio process as shown in Figure 1, that the utility model provides comprises audio frequency input module, input processing module, four-way output processing module and audio frequency output module.
The audio frequency input module comprises digital left channel, digital right channel, simulation L channel and simulation R channel.
Input processing module comprises first input processing unit 11 and second input processing unit 12.
The four-way output processing module comprises first to fourth output treatment channel, and every treatment channel comprises one-level processing unit 211, high pass filter 212 and the two stage treatment unit 213 that is electrically connected successively.One-level processing unit 211 comprises signal mixer, gain controller, phase controller, delay controller and the 5 sections parametric equalizers that are electrically connected successively; Two stage treatment unit 213 comprises 2 sections parametric equalizers, low pass filter, compressor, gain controller, phase controller and silence switch that are electrically connected successively.Said compressor is pressed the compressor of limit mode for adopting RMS.
As improvement, said two stage treatment unit 213 also comprises the signal averaging calculator, and the collection of signal averaging calculator is input to the signal of two stage treatment unit 213 and calculates its mean value.
The audio frequency output module comprises first to fourth channel output end, is electrically connected on the end of first to fourth output treatment channel of above-mentioned correspondence respectively.
As shown in Figure 2, the Audio Signal Processing process of the utility model four-way audio process mainly may further comprise the steps:
The audio signal input: after the external audio signal was linked into the audio frequency input module, digital left channel, digital right channel, simulation L channel and simulation R channel were input to the audio signal of corresponding sound channel in the input processing module.Wherein, Digital left channel is input to first input processing unit 11 and second input processing unit 12 simultaneously; Digital right channel also is input to first input processing unit 11 and second input processing unit 12 simultaneously; The simulation L channel is input to first input processing unit 11, and the simulation R channel is input to second input processing unit 12.
The signal disposed of in its entirety: with first input processing unit 11 is example; Signal selector is according to user's operation; Select in three sound channels of input, the signal of selecting carries out overall gain adjusting, phase adjusted, always delays time that adjusting, denoising and parameter are balanced to be regulated through gain controller, phase controller, delay controller, Noise gate and 5 sections parametric equalizers successively.Second input processing unit 12 is also handled according to same flow process the signal of another sound channel of selecting simultaneously.It should be noted that the signal that first input processing unit 11 and second input processing unit 12 are selected can only be digital signal or analog signal simultaneously.
Four-way output is handled: the audio signal that first input processing unit 11 and second input processing unit 12 are handled back output is input to first to fourth output treatment channel simultaneously.With the first output treatment channel is example; After the two paths of signals that is input to one-level processing unit 211 mixes, carry out balanced adjusting of the gain-adjusted first time, phase adjusted, time-delay adjusting and parameter in the passage through gain controller, phase controller, delay controller and 5 sections parameter balance controllers successively in signal mixer.Through high pass filter 212 filters low interference signals, be input to again in the two stage treatment unit 213 then.In two stage treatment unit 213; Signal carries out balanced adjusting of the parameter second time through 2 sections parametric equalizers; Pass through the low pass filter filters out high-frequency interferencing signal again; Press limit control through compressor again; Prevent that the phenomenon of blasting and sonic boom from appearring in the audio signal of exporting, then successively through gain controller and phase controller carry out the second time gain-adjusted with phase adjusted for the second time, whether control audio signal after this passage is handled for effectively exporting signal through a silence switch at last.Wherein, The pressure limit mode of compressor can be pressed limit for RMS; To this pressure limit mode, can also outside the front of 2 sections parametric equalizers, connect a signal averaging calculator, the collection of signal averaging calculator is input to the signal of two stage treatment unit 213 and calculates its mean value; Again mean value is shown to external circuit, the user can do suitable adjustment to compressor with reference to this mean value.Other three output treatment channel are also handled the signal of corresponding input according to above-mentioned flow process simultaneously.The user can carry out different gains, phase place, time-delay to first to fourth output treatment channel, parameter is balanced and press the limit adjustment, thereby makes the audio signal of each passage output have different audios.
Audio signal output: the audio signal after first to fourth output treatment channel is handled is exported through first to fourth corresponding channel output end respectively.Because the audio signal of each passage output has different audios, so also difference of the audio of the audio signal of exporting at first to fourth channel output end of correspondence, four tunnel audio signals are exported simultaneously, are mixed into different stereophonic effects.
The above embodiment has only expressed a kind of execution mode of the utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection range of the utility model.Therefore, the protection range of the utility model patent should be as the criterion with accompanying claims.
