Embodiment one
First embodiment of the invention provides a kind of concrete methods of realizing of transducing audio vocal technique, as shown in figure 3, institute
The method of stating comprises the following steps：
Step 301：Acoustical frequency spectrum information is gathered, establishes acoustical frequency spectrum information bank；
In actual applications, because sound is a kind of sound wave with certain frequency of oscillation, and sound wave has frequency of oscillation, shaken
The physical parameters such as width, waveform or characteristic, it is exactly these different parameters and characteristic, just causes sound there are a variety of sense of hearings
Effect.If divided according to the characteristic voice of various musical instruments, there is the different performance shape of four kinds of tone, volume, tone color and figure etc.
Formula, is exactly these different forms, the characteristics of just determining various different musical instrument sounds.Wherein, tone is shaken with electromagnetic wave
Swing a kind of form of frequency dependence, and frequency is directly proportional, frequency is high, then tone is just high, and frequency is low, then tone is also low；Volume is
A kind of form related to the oscillation amplitude of electromagnetic wave, its size is directly proportional to the amplitude of electromagnetic wave, and amplitude is big, volume with regard to big,
Amplitude is small, and volume is also small.Compare from us intuitively for auditory effect, tone height, then the sound hair tip sent, thin, tone
Low, the sound sent seems simple and honest.
And tone color then refers to the sense quality of sound, i.e. people hear the auditory effect of sound, the sound difference of different people
Exactly distinguished by tone color.Equally it is soprano, even if they sing the sound of same first song, Li Guyi and Song Zuying, Ting Zhongyi
Can is listened accurately to distinguish, here it is the effect of tone color.And tone color is determined by the waveform of above-mentioned electromagnetic wave
Fixed.The waveform of standard electromagnetic wave is sine wave, such as the alternating current that our conventional days, and its waveform is exactly a kind of sine of standard
Ripple.But the sound of people, the sound of various musical instruments, and a variety of sound in nature, its waveform be often it is a kind of compared with
For the shape of complexity, exactly these waveforms of different shapes, the tone colors of alternative sounds is just determined.The tone color of sound is except can
To represent (time-domain representation that waveform is sound) by waveform outside, it can also represent that (frequency spectrum is the frequency of sound by sound spectrum
Domain representation), by carrying out Fourier transformation to a bit of waveform of sound, you can obtain the sound audio corresponding to this section of waveform
Spectrum.
Because the sound of same tone color may have a variety of different waveforms, but the frequency spectrum of the sound of same tone color is past
Past is identical, thus the Main Basiss being had different timbres usually using sound spectrum as differentiation alternative sounds.
In the embodiment of the present invention, in order to realize the effect for imitating different people sound, the present invention needs to treat mould in advance
Imitative people carries out sound collection, and the acoustical frequency spectrum information of the user is extracted from the voice data collected, specifically, music
APP can gather the acoustic information of singer in advance, and the acoustical frequency spectrum letter of those singers is extracted from the audio-frequency information collected
Breath；Or active user can also utilize the voice input device of terminal, for example, microphone, the sound of typing oneself, and lead to
Cross music APP the sound of oneself uploads onto the server, to cause server to extract the acoustical frequency spectrum information of the user.
In actual applications, when gathering acoustical frequency spectrum information, it is only necessary to gather 20 basic acoustical frequency spectrums, pass through
This 20 basic acoustical frequency spectrums can be combined into more than 400 kinds of acoustical frequency spectrum combination entirely, so as to pass through this more than 400 kinds of acoustics frequencies
Spectrum is combined to simulate the sound of the user.
