Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
One embodiment of the invention discloses a kind of processing method of voice data, and the method can be applied in electronic equipment.
Wherein, electronic equipment can be the equipment such as notebook computer, panel computer, mobile phone.
This electronic equipment comprises N number of dio Output Modules, and the concrete number of dio Output Modules does not limit in the present invention, as long as ensure N >=2.As in the ordinary course of things, electronic equipment comprises the true output effect that 4 dio Output Modules just can ensure sound.
As shown in Figure 1, the method can comprise the following steps:
Step 101: receive original audio data signal, original audio data signal is converted to N channel voiceband data signal;
Wherein, the sound channel number of voiceband data signal after the conversion of original audio output signal and the number of dio Output Modules are consistent.No matter original audio data signal is the sound channel of which kind of type, is all converted into N channel voiceband data signal.Concrete, original audio data signal can comprise stereo, 5.1 sound channels, 7.1 sound channels etc.
It should be noted that, if original audio data signal originally N channel voiceband data signal, then without the need to changing.
Suppose that the number of dio Output Modules is 4, so, then need original audio data signal to be converted to 4 channel audio data-signals.As, original audio data signal is 5.1 sound channels, adopt left (L), in (C), right (R), left back (LS), right back (RS) five direction output sounds, and the original audio data signal of 5.1 sound channels is converted to 4 channel audio data-signals, adopt front left, front right, rear left, rear right four direction output sound.
Step 102: processed N channel voiceband data signal by pre-established acoustic model, generates N road voiceband data signal;
Wherein, acoustic model sets up according to the effect of true people's ear audition, can be determined and the sound channel corresponding to each dio Output Modules by this acoustic model, thus generate a road voiceband data signal corresponding with each dio Output Modules.
It should be noted that, each road voiceband data signal all can comprise the main sound channel voiceband data signal and supplemental channel voiceband data signal that are different from other road voiceband data signals; And the supplemental channel voiceband data signal in each road voiceband data signal is weakened by the supplemental channel voiceband data signal of other road voiceband data signals.
For the ease of understanding, be briefly described for 4 road voiceband data signals, 2 road voiceband data signals specifically comprise the first via voiceband data signal corresponding with the first dio Output Modules, the second road voiceband data signal corresponding with the second dio Output Modules, the three road voiceband data signal corresponding with the 3rd dio Output Modules, the four road voiceband data signal corresponding with the 4th dio Output Modules.The main sound channel voiceband data signal supposing first via audio output signal is " front left " channel audio data-signal, and so the supplemental channel voiceband data signal of first via audio output signal comprises " front right ", " rear left " and " rear right " audio output signals; Accordingly, the main sound channel voiceband data signal of the second road voiceband data signal is " front right " channel audio data-signal, and the supplemental channel voiceband data signal of the second road voiceband data signal comprises " front left ", " rear left " and " rear right " channel audio data-signal; Accordingly, the main sound channel voiceband data signal of the 3rd road voiceband data signal is " rear left " channel audio data-signal, and the supplemental channel voiceband data signal of the 3rd road voiceband data signal comprises " front left ", " front right " and " rear right " channel audio data-signal; Accordingly, the 4th road voiceband data signal is " rear right " channel audio data-signal, and the 4th road voiceband data signal comprises " front left ", " front right " and " rear left " channel audio data-signal.
In this application example, for first via voiceband data signal, the supplemental channel voiceband data signal of first via voiceband data signal, namely " front right ", " rear left " and " rear right " audio output signals are weakened by the supplemental channel voiceband data signal of other road voiceband data signals, accordingly, the supplemental channel of first via voiceband data signal also can weaken the supplemental channel voiceband data signal of other road voiceband data signals accordingly.
Step 103: described N road voiceband data signal is exported respectively to dio Output Modules corresponding thereto.
In acoustic model, each dio Output Modules which voiceband data signal corresponding is all simulated according to actual conditions, therefore, need export each road voiceband data signal to the dio Output Modules corresponding with this road voiceband data signal.The first dio Output Modules as corresponding in first via voiceband data signal, then exported first via voiceband data signal by the first dio Output Modules.
It should be noted that, because the supplemental channel voiceband data signal of each road audio output signal is weakened by the supplemental channel voiceband data signal of other road voiceband data signals, therefore, the effect of the main sound channel audio output signal that each dio Output Modules is exported strengthens, and the master voice audio output signal that different dio Output Modules exports is different, the sound wave exported by utilizing different dio Output Modules is in space and temporal correlation, each dio Output Modules is cooperated with each other, ensure that sound can project from different perspectives.
