Wherein, octave can be the spectrum space that frequency doubles occupied by frequency spectrum, for different initial frequency point frequency multiplication occupied by spectrum space be not identical, such as initial frequency point is 100HZ, then an octave is exactly from 100HZ ~ 200HZ, if starting point frequency is 200HZ, then an octave is exactly from 200HZ ~ 400HZ, if starting point frequency is 400HZ, then an octave is exactly from 400HZ ~ 800HZ ... by that analogy.Namely 1/N octave signal arranges 12 frequencies in an octave, is spaced apart 1/12 octave between each, and concrete account form can be as follows:
Such as: from 100HZ ~ 200HZ, and frequency interval is 1/12 octave, if first Frequency point is 1/12=lgx/lg2, lgx=0.3010 × 1/12=0.025, x=1.055, the frequency that first Frequency point is corresponding is 100HZ*1.055=105.5HZ.For second Frequency point 2/12=lgx/lg2, lgx=0.3010 × 2/12=0.0501, x=1.122, the frequency that second Frequency point is corresponding is 100HZ*1.122=112.2HZ, by that analogy.
After the first audio signal preset play by target playback equipment, the microphone of mobile terminal can detect the first audio signal, microphone can by the first audio signal transmission of detecting to the processor of mobile terminal, and the processor of mobile terminal then can determine the parameter value of the target signal parameters of the first audio signal that microphone detects.It is one or more that target signal parameters can comprise in frequency response, level and phase place.Wherein, frequency response also can be called frequency response, for representing the signal magnitude of the first audio signal at this Frequency point; When level can receive this Frequency point for expression arbitrarily, the size of the first audio signal; Phase place may be used for representing the time receiving the first audio signal.Processor can determine the frequency response of each Frequency point in the first audio signal, level and phase place, to carry out subsequent treatment.
In a step 102, according to the parameter value of the target signal parameters determined, determine the calibration adjusted value of target signal parameters.
In force, after the frequency response of each Frequency point in the first audio signal that mobile terminal determination microphone detects, level and phase place, can according to the frequency response of each Frequency point, determine the calibration adjusted value of the frequency response of each Frequency point, according to the level of each Frequency point, determine the calibration adjusted value of the level of each Frequency point, according to the phase place of each Frequency point, determine the calibration adjusted value of the phase place of each Frequency point.
Optionally, can calibrate according to the fiducial value of target signal parameters, accordingly, the processing procedure of step 102 can be as follows: according to the parameter value of the target signal parameters determined, and the fiducial value of the target signal parameters prestored, determine the calibration adjusted value of target signal parameters.
In force, can comprise multiple Frequency point in the first audio signal, mobile terminal can determine the frequency response of each frequency in the first audio signal that microphone detects, level and phase place.For the situation of calibration frequency response, can prestore the fiducial value of frequency response in mobile terminal, this fiducial value can be stored in advance in above-mentioned application program by technical staff, also can be calculated by mobile terminal.After mobile terminal determines the frequency response of each frequency in the first audio signal, can by the fiducial value algorithm preset, calculate the fiducial value of frequency response, the method calculating the fiducial value of frequency response has a lot, such as, can calculate the mean value of the frequency response determined, using the fiducial value of this mean value as frequency response, or in the frequency response determined, determine maximum frequency response value and minimum frequency response value, using the fiducial value of the mean value of the two as frequency response.After the fiducial value of mobile terminal determination frequency response, the difference of the fiducial value that can calculate frequency response and the frequency response value of each Frequency point determined, using the difference the determined calibration adjusted value as frequency response corresponding to each Frequency point.Such as, mobile terminal detects that the frequency response of 1K Frequency point is 20dB, and the fiducial value of frequency response is 25dB, then can determine that the calibration adjusted value of 1K Frequency point is 5dB.In practice, technical staff can arrange the fiducial value of frequency response corresponding to all Frequency points, also can arrange the fiducial value of frequency response corresponding to each Frequency point.
For the situation of calibration level, the fiducial value of level can be arranged by technical staff, and be stored in above-mentioned application program, after mobile terminal determines the level of each Frequency point, can the fiducial value of compute level and the difference of the level value of each Frequency point determined, using the difference the determined calibration adjusted value as level corresponding to each Frequency point.Such as, mobile terminal detects that the level of 1K Frequency point be the fiducial value of the level of 20dB, 1K Frequency point is 25dB, then can determine that the calibration adjusted value of the level of 1K Frequency point is 5dB.In practice, technical staff can arrange the fiducial value of level corresponding to all Frequency points, also can arrange the fiducial value of level corresponding to each Frequency point.
For the situation of calibration phase place, the interval duration that the play time of the first audio signal is corresponding can be prestored in mobile terminal, the play start time point of the first audio signal can be the time point that mobile terminal starts the first audio signal to send to target playback equipment, and then play start time point can be added the time point of interval duration, as the intended recipient time point of microphone.Such as, the play time of the first audio signal is 10: 20: 15, and interval duration is 1S, then the intended recipient time point of microphone is 10: 20: 16.Mobile terminal can prestore the phase place of each Frequency point in the first audio signal in this locality, and then can according to interval duration, obtain the phase place of each Frequency point in the first audio signal after time delay, using the fiducial value of the phase place of each Frequency point in the first audio signal after time delay as phase place.After mobile terminal determines the phase place of each Frequency point, the difference of the fiducial value that can calculate phase place and the phase value of each Frequency point determined, using the difference the determined calibration adjusted value as phase place corresponding to each Frequency point.Such as, mobile terminal detects that the phase place of 1K Frequency point is 3 π/5, and the fiducial value of the phase place of 1K Frequency point is pi/2, then can determine that the calibration adjusted value of the phase place of K Frequency point is 1 π/10.
Optionally, the fiducial value of target signal parameters can be determined according to the type of target playback equipment, corresponding processing procedure can be as follows: the type information obtaining target playback equipment, according to the corresponding relation of the type information the prestored fiducial value corresponding with target signal parameters, determine the fiducial value of the target signal parameters that the type information of target playback equipment is corresponding; According to the parameter value of the target signal parameters determined, and the fiducial value of target signal parameters corresponding to the type information of target playback equipment, determine the calibration adjusted value of target signal parameters.
In force, the type of target playback equipment can be diversified, for home theater, can be divided into: the home theater etc. of the home theater of two sound equipments, the home theater of five sound equipments and seven sound equipments.When the type of target playback equipment is different, the fiducial value of target signal parameters also can be different.User holds after in movement according to the dynamic image in homepage, can click and start to calibrate option, mobile terminal then can receive calibration command, then can display the play the list of types of equipment, user can option corresponding to type (can be called the first kind) corresponding to select target playback equipment, what mobile terminal then can receive the corresponding first kind chooses instruction, the corresponding relation of fiducial value that then can be corresponding with target signal parameters according to the type information prestored, determines the fiducial value of the target signal parameters that the first kind is corresponding.Such as, the fiducial value that can prestore level corresponding to the home theater of two sound equipments in mobile terminal is 50dB, the fiducial value of phase place is 10, the fiducial value of the level that the home theater of five sound equipments is corresponding is 40dB, the fiducial value of phase place is 15, the fiducial value of the level that the home theater of seven sound equipments is corresponding is 30dB, the fiducial value of phase place is 17, then when the type that user chooses is the home theater of five sound equipments, mobile terminal can determine that the fiducial value of the level that the type of target playback equipment is corresponding is 40dB, and the fiducial value of phase place is 15.In the first audio signal that mobile terminal can also detect according to microphone, the frequency response of each Frequency point, determines the fiducial value of frequency response, concrete method and above-mentioned processing procedure similar, repeat no more.
In step 103, in the process of carrying out audio frequency broadcasting, according to the calibration adjusted value of target signal parameters, audio signal to be played is calibrated, the audio signal transmission to be played after calibration is play to target playback equipment.
In force, after the calibration adjusted value of mobile terminal determination target signal parameters, can store the calibration adjusted value of target signal parameters.When user wishes to play certain audio frequency, user can click icon corresponding to this audio frequency, mobile terminal then can receive should the play instruction of audio frequency, obtain the voice data of this audio frequency, obtain audio signal to be played, then according to the calibration adjusted value of target signal parameters, audio signal to be played can be calibrated, audio signal transmission to be played after calibration is play to target playback equipment, as shown in Figure 2.
