Based on above-mentioned mobile terminal hardware configuration and communication system, each embodiment of the inventive method is proposed.
With reference to Fig. 3, in one embodiment, the method for this multi-channel sound collection comprises:
Step S101, master mobile terminal and at least one secondary mobile terminal connect, and carry out system time calibration;
In the present embodiment, master mobile terminal and secondary mobile terminal can be all mobile phone or computer etc., and in collection sound source data process, by a station terminal as master mobile terminal, other terminal is as secondary mobile terminal.Master mobile terminal and secondary mobile terminal all only support a microphone, and the quantity of master mobile terminal only has one, and secondary mobile terminal then can have one or more, and the present embodiment only has one to be described for secondary mobile terminal.
In the present embodiment, wifidirect can be set up between master mobile terminal with secondary mobile terminal and be connected.System time between terminal is generally different, therefore, before master mobile terminal and secondary mobile terminal carry out multi-channel sound collection, first master mobile terminal and secondary mobile terminal are connected, initiated to connect by master mobile terminal, such as both set up wireless wifi connection etc.Then, whether the system time of both judgements is identical, if the same do not need to carry out time calibration, otherwise needs to carry out time calibration.After calibration, master mobile terminal is identical with the system time of secondary mobile terminal.
In the present embodiment, Time synchronization technique (as gps time simultaneous techniques, internet time simultaneous techniques etc.) can be passed through and carry out time calibration, obtain the time difference between master mobile terminal and secondary mobile terminal, and both system times are adjusted to consistent.
Step S102, gather in the process of same sound source data at master mobile terminal and at least one secondary mobile terminal, described master mobile terminal gathers the first sound source data, and receives the second sound source data of at least one secondary mobile terminal collection;
In the present embodiment, master mobile terminal and at least one secondary mobile terminal gather same sound source data, and the sound source data of master mobile terminal collection is the first sound source data, and the sound source data of secondary mobile terminal collection is the second sound source data.Second sound source data, after collecting the second sound source data, is transferred on master mobile terminal by secondary mobile terminal, is received the second sound source data of secondary mobile terminal transmission by master mobile terminal.
Step S103, carries out multichannel synthesis by described first sound source data and the second sound source data, obtains multichannel source data.
In the present embodiment, in master mobile terminal, after the second sound source data receiving secondary mobile terminal, master mobile terminal intercepts the first sound source data and the second sound source data according to the time difference starting to gather, part identical in both interceptings carries out multi-channel data synthesis, obtains multichannel source data.
Wherein, secondary mobile terminal will collect the second sound source data (comprising acquisition time stamp etc.) and be sent on master mobile terminal, such as, set up wifidirect between master mobile terminal with secondary mobile terminal to be connected, then the second sound source data is sent to master mobile terminal by secondary mobile terminal.At master mobile terminal, not at once the first sound source data is saved in multichannel file after collecting the first sound source data, but the first sound source data is cached in internal memory.Waiting receive the second sound source data that secondary mobile terminal sends after, the second sound source data received equally first is buffered in internal memory, consider that the time that both start to gather may be different, therefore need to compare according to both timestamp time of carrying out, abandon in master mobile terminal and secondary mobile terminal the sound source data failing simultaneously to collect, i.e. nonsynchronous sound source data for the previous period, intercept corresponding sound source data, this sound source data as each sound channel is synthesized, equally, at the end of collection, abandon in both the sound source data failing simultaneously to collect, encode according to set file layout afterwards, finally be written in multichannel file, obtain multichannel source data.
Such as when secondary mobile terminal only has one, the first sound source data and the second sound source data sound source data as left and right acoustic channels can be synthesized, obtain two-channel sound source data.
In the present embodiment, when using master mobile terminal and secondary mobile terminal to carry out multi-channel sound recording, such as, when carrying out binaural sound recording, breach two microphone recording in the past and need to depend on condition terminal must being supported two microphones, user only can support the terminal of single microphone by use two, realize real two microphone recording.Further, owing to using two station terminals, the microphone when gathering for gathering sound source data can not as the restriction by distance a station terminal, and user can regulate according to demand voluntarily, reaches good two microphone recording effects.
Compared with prior art, the present embodiment gathers same sound source data by using master mobile terminal and at least one secondary mobile terminal, master mobile terminal and secondary mobile terminal all only support a microphone, like this when multitrack recording, the second gathered sound source data is sent to master mobile terminal by secondary mobile terminal, in both the first sound source data that self gathers by master mobile terminal intercepts with the second sound source data, identical part carries out multichannel synthesis, obtain multichannel source data, real multichannel effect can be reached, and, no matter be master mobile terminal or secondary mobile terminal, all only has a microphone, therefore, when multitrack recording, the distance of microphone is not by the restriction of terminal, user can regulate according to demand voluntarily, reach good multitrack recording effect.
In a preferred embodiment, as shown in Figure 4, on the basis of the embodiment of above-mentioned Fig. 3, above-mentioned steps S103 comprises:
Step S1031, subtracts each other the beginning acquisition time of the first sound source data and the beginning acquisition time of the second sound source data and obtains time difference;
