Below in conjunction with specific embodiment, technical scheme of the present invention is described in further detail.
Embodiment 1
The present embodiment is the interactive mode as two mobile phones by bluetooth, give another mobile phone (client) the audio file real-time Transmission of a mobile phone (host), before broadcasting, automatically judge left and right putting position, and just starting to adjust volume and frequency response curve in the short time of playing, to reach the played in stereo effect of better fitness.The concrete scene of the present embodiment as shown in Figure 9.
In the present embodiment, the specific works flow process of two mobile phones comprises:
1) two mobile phones are put on the table according to the position shown in Fig. 9, and host machine adopts bluetooth to be connected with client machine.
2) the two mic of Host machine start working, and client machine sends confirmation sound after bluetooth successful connection; The two mic of Host machine can know client in left side or right side according to the priority arrival order of sound wave, if host machine right side mic first receive sound wave host machine will oneself be made as L channel and play; If host machine left side mic first receive sound wave host machine will oneself be made as R channel and play (automatic discrimination left and right putting position).
3) host machine sends played file (being generally mp3 form) by bluetooth to client machine, and both sides all start decoding and play (with passing with separating) simultaneously.
4) host machine list mic work, record the sound (data of 2-3s) of current broadcasting, be stored in internal memory (comprising left and right acoustic channels) in pulse code modulation (PCM) stream mode, the data of himself broadcast decoder also buffer memory equal time at internal memory;
Wherein, host machine now has five data (suppose host machine sowing put be L channel), respectively: left and right acoustic channels the mixings PCM that L channel source PCM stream, R channel source PCM stream, play parameter (comprising the data such as volume, EQ, self loudspeaker parameters), recording parameter (comprising the data such as volume, self mic parameter) and mic record flows.
5) host machine (suppose host machine sowing put be L channel) is by L channel source PCM stream, play parameter (comprising the data such as volume, EQ, self loudspeaker parameters), recording parameter (comprising the data such as volume, self mic parameter), can obtain the approximation (environmental factor is returned certain interference) of the L channel PCM flow point amount that mic records; The left and right acoustic channels mixing PCM stream of recording according to mic again can be isolated another sound channel PCM flow data that mic records by the principle of stacking of sound wave.
6) the R channel PCM stream that the L channel PCM stream that relatively mic records and mic record, send volume according to difference host machine to client machine and adjust instruction and frequency response curve adjustment instruction, if client machine can return to OK according to this numerical value adjustment, left and right acoustic channels now reaches identical parameters substantially, and the match is successful in stereo playback; If client machine cannot be adjusted (as certain parameter has reached maximum according to this numerical value, cannot continue to increase), can return to Fail, and parameter and the distance value that cannot adjust are returned, host machine is with regard to the play parameter of this parameter adjustment oneself, to reach consistency.
It should be noted that, host machine and client machine can record pair relationhip and corresponding parameter adjustment, just no longer need the flow processs such as PCM comparative analysis when these two equipment coordinate again next time, directly set according to memory host machine and the client machine adjusted.
It should be noted that, more than calculate separate obtain the left and right acoustic channels that mic records method in fact also the simple method of interchangeable one realize, in the time starting to play, first record by mic the initial 2-3 second that L channel is play, record R channel by mic again and play corresponding 2-3 second, this method has been saved the amount of calculation that separates the left and right acoustic channels mixing PCM stream of recording, but because being all former seconds calculates the adjustment time, just start afterwards from the beginning to play, so user experiences generally.
The present invention is not changing under the prerequisite of hardware, realizes the stereo playback of high-quality can have at one's side two equipment time, and needn't remove to buy the active audio amplifier that is not easy to carry again, and has not only saved spending but also saved space.And implementation algorithm of the present invention is simple, the operational capability of current high-end mobile AP can be competent at the analytical calculation in the present invention substantially, thereby practicality and feasibility are higher.
The above, be only preferred embodiment of the present invention, is not intended to limit protection scope of the present invention.
