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, the audio frequency of a mobile phone (host)Transmitting file in real time is given another mobile phone (client), automatically judges left and right putting position before broadcasting, andIn the short time that has just started to play, adjust volume and frequency response curve, broadcast to reach the stereo of better fitnessPut effect. 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 and client machine adopt bluetooth to connectConnect.
2) the two mic of Host machine start working, and client machine sends confirmation sound after bluetooth successful connection; HostThe two mic of machine can know client in left side or right side according to the priority arrival order of sound wave, if host machineRight side mic first receive sound wave host machine will oneself be made as L channel play; If host machine left side mic first receivesTo sound wave host machine will oneself be made as R channel play (automatic discrimination left and right putting position).
3) host machine sends played file (being generally mp3 form) by bluetooth to client machine, the while twoLimit all starts decoding and plays (with passing with separating).
4) host machine list mic work, records the sound (data of 2-3s) of current broadcasting, with pulseCoded modulation (PCM) stream mode is stored in internal memory (comprising left and right acoustic channels), the number of himself broadcast decoderAccording to also buffer memory equal time at internal memory;
Wherein, host machine now has five data (suppose host machine sowing put be L channel), respectively: a left sideChannel source PCM stream, R channel source PCM stream, play parameter (comprise volume, EQ, self loudspeaker ginsengThe data such as number), recording parameter (comprising the data such as volume, self mic parameter) and mic left side of recordingR channel mixing PCM stream.
5) host machine (suppose host machine sowing put be L channel) by L channel source PCM stream, play ginsengNumber (comprising the data such as volume, EQ, self loudspeaker parameters), recording parameter (comprise volume, self micThe data such as parameter), (environmental factor is returned can to obtain the approximation of the L channel PCM flow point amount that mic recordsThere is certain interference); The left and right acoustic channels mixing PCM stream of recording according to mic again can be former by the stack of sound waveReason is isolated another sound channel PCM flow data that mic records.
6) the R channel PCM stream that the L channel PCM stream that relatively mic records and mic record, according to poorValue host machine sends volume to client machine and adjusts instruction and frequency response curve adjustment instruction, if client machine can be pressedOK is returned in numerical value adjustment like this, and left and right acoustic channels now reaches identical parameters substantially, stereo playbackBe made into merit; If client machine cannot (as certain parameter has reached maximum, cannot continue according to the adjustment of this numerical valueIncrease), can return to Fail, and parameter and the distance value that cannot adjust are returned, host machine is adjusted with regard to this parameterWhole oneself play parameter, to reach uniformity.
It should be noted that, host machine and client machine can record pair relationhip and corresponding parameter adjustment,When these two equipment coordinate again next time, just no longer need the flow processs such as PCM comparative analysis, directly according to noteRecall host machine and the client machine adjusted of setting.
It should be noted that, above calculating separates that to obtain the method for the left and right acoustic channels that mic records in fact also interchangeableA kind of simple method realizes, and in the time starting to play, first records 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 and has been separated the left and right acoustic channels of recordingMix the amount of calculation of PCM stream, but owing to being all former seconds to calculate the adjustment time, just start from the beginning afterwardsPlay, so user experiences generally.
The present invention is not changing under the prerequisite of hardware, realizes high-quality solid can have at one's side two equipment timeSound playback, and needn't remove again to buy the active audio amplifier that is not easy to carry, not only save 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 this substantiallyAnalytical calculation in invention, thus practicality and feasibility are higher.
The above, be only preferred embodiment of the present invention, is not intended to limit protection model of the present inventionEnclose.
