S202 is based on the feature frequency response curve, the sample frequency information and the sample timbre information, obtains sample The digital equalising processing curve of this audio and the reverberation parameters of sample audio；
It is understood that the principle of digital equalising processing is：Input signal " X " is established into corresponding output signal " Y ", Y =f (X) includes the function of one and " X " respective frequencies " k " again wherein in this action type of f ().The function of " X " will be corresponded to Expression formula expansion i.e. Y=g (k) * X, wherein g () change with digital equalising parameter regulation.In embodiments of the present invention, The input signal " X " is sample frequency information, the sample timbre information and feature frequency response curve, the frequency " k " For the corresponding frequency values of the feature frequency response curve.Based on above-mentioned handling principle, produces digital equalising and handle curve.Such as Fig. 4 It is shown a kind of digital equalising processing curve, abscissa is frequency, and ordinate is digital equalising parameter, the digital equalising processing Curve is change curve of the digital equalising parameter with frequency.
Meanwhile it being based on the feature frequency response curve, the sample frequency information and the sample timbre information, it can be obtained The reverberation parameters of sample audio.Wherein, the generation of reverberation is since a sound producing body is after sending out sound wave, and sound wave is via sky The surface that gas touches barrier will be reflected, and due to the complexity of actual environment, result in the sound that a source of sound is sent out Sound will produce various echo from all directions, after these sound mix, be formed so-called reverberation.Reverberation First sound is " direct sound wave ", that is, source sound, and dry voice output is called in effect device, is to send out direct arrival from sound The sound of audience's ear and the chief component of sound pressure level.The propagation attenuation of sound pressure level and distance square are inversely proportional, i.e., Distance doubles, and sound pressure level reduces 6dB.Subsequent several apparent sound being separated by out are called " early reflected sound ", again Claim nearly secondary reflection sound, is that the sound that sends out of sound source is reached after ambient interfaces (wall and ceiling, ground) reflect 1~2 time and listened The sound of many ears, the reflected sound reached within 50ms more late than direct sound wave belong to this range, and sound is bigger, brighter It is aobvious, it can reflect source sound in space, ear and distance relation between the walls.The characteristics of reflection is that ear can not It and direct sound wave are distinguished, can only be superimposed them impression.Therefore reflection is to improving sound pressure level harmony The clarity of sound is beneficial.Its propagation attenuation is related with the sound absorption characteristics of reflecting interface.The last one sound is " reverberation sound ", is The multiple reflections sound to 50ms or more more late than direct sound wave.For music, though reverberation sound can increase the richness of music, it But the clarity that sound can be reduced while increasing fullness can make sound send out " dry " when too small, can not be excessive.Reverberation The size of sound is directly related with the sound absorption characteristics of ambient interfaces.
The reverberation parameters may include reverrberation intensity, reverberation time, nephelometric turbidity unit and reverberation density etc..Wherein, reverberation The time uninteresting hair shaft of short sound, long sound is again confused to lose a large amount of details, and the suitable reverberation time can not only beautify Sound covers musical instrument noise, and musical sound fusion can also be made to increase the continuity of loudness and syllable.It should be noted that a sample This audio corresponds to a reverberation parameters.
S203 obtains the sample audio label of the sample audio, is based on equal loudness contour and the sample audio label, The octave characteristic point handled in curve in selected frequency range the digital equalising is adjusted, to obtain each octave The corresponding digital equalising parameter of characteristic point；
Specifically, the sample audio label may include that rock and roll, metal music, folk song and disco etc. are different types of Style of song, and may include at least one sample audio label per class sample audio label, as sample audio label " rock and roll " can be with Including " Art Rock, punk, Post rock, stone roller core etc. " sample audio label.The sample sound for obtaining the sample audio Criterion label, it is to be understood that the sample audio label for obtaining sample audio, based on sample audio label as shown in Figure 2 with The correspondence of sample audio label, you can get the sample audio label of sample audio.For example, sample audio is " grey aunt Ma ", the sample audio label of " Cinderella " they are " popular metal ", then table look-up 2 it is found that " popular metal " belongs to " metal music ", Therefore, the sample audio label of " Cinderella " is " metal music ".
The equal loudness contour be description etc. ring under the conditions of sound pressure level and frequency of sound wave relation curve, be aural signature it One.Pure tone i.e. at different frequencies needs which kind of sound pressure level reached, and could obtain consistent hearing loudness for hearer.Such as Fig. 5 show a kind of pure tone equal loudness contour figure, and abscissa is frequency, and ordinate is sound pressure level.Acoustic pressure is that atmospheric pressure is disturbed The variation generated afterwards, the i.e. overbottom pressure of atmospheric pressure, it is equivalent to pressure change caused by being superimposed a disturbance on atmospheric pressure. Sound pressure level indicates that unit dB is defined as the ratio of acoustic pressure virtual value p (e) to be measured and reference sound pressure p (ref) with symbol SPL Value takes common logarithm, multiplied by with 20.The sound pressure level of different frequency in figure corresponding to every curve is different, but human ear sense The loudness felt is the same, and every curve indicates the variation relation of different loudness side's lower frequencies and sound pressure level.By equal loudness contour It is known that when loudness is smaller, human ear is insensitive to high bass perception for race, and when loudness is larger, high bass perception is gradually clever It is quick.
The digital equalising parameter is exactly to adjust the yield value of signal after the signal of each frequency range in digital equalising processing curve, The digital equalising parameter is corresponded with each octave characteristic point.Wherein, the octave characteristic point, as by discrete frequency Spectrum is divided into frequency range one by one, and so that the upper limiting frequency of each frequency range is doubled than lower frequency limit, (namely frequency is 2:1 frequency The frequency band at interval), to obtain multiple octaves, then characteristic point is taken in each octave respectively.If for example, signal frequency Ranging from 63Hz~16kHz, can be divided into 8 octaves, and respectively 63Hz~126Hz, 126Hz~252Hz, 252Hz~ 504Hz, 504Hz~1.08kHz, 1.008kHz~2.016kHz, 2.016kHz~4.032kHz, 4.032kHz~8.064kHz And 8.064Hz~16kHz, then characteristic point is taken in each octave.It, then will each again if 1/24 octave characteristic point Sound interval is divided into 24 frequency ranges, a 1/24 octave characteristic point of each frequency range as the octave, each 1/24 octave Characteristic point corresponds to a digital balance parameters, is adjusted to the corresponding digital equalising parameter of each 1/24 octave characteristic point, To determine a suitable parameter area for each 1/24 octave characteristic point.

Figure 12 is referred to, for an embodiment of the present invention provides the structural schematic diagrams of another audio effect processing equipment.Such as Figure 12 Shown, the audio effect processing equipment 1 of the embodiment of the present invention may include：Information acquisition unit 11, parameter acquiring unit 12, number Believe according to output unit 13, sample information acquiring unit 14, sample parameter acquiring unit 15, sample parameter adjustment unit 16 and sample Cease storage unit 17.
Sample information acquiring unit 14 is used for collecting sample audio, obtains the feature frequency response curve of the sample audio, and Obtain the sample frequency information and sample timbre information of the sample audio；
It is understood that audio is a kind of important media in multimedia, it is the form of voice signal.As one kind The carrier of information, audio can be divided into voice, music and other sound three types, in embodiments of the present invention, the sample sound Frequency is music, and the sample audio is at least one music for storage of user selected in more songs.For May include much information for one sample audio, such as sample audio data, frequency information, timbre information, Ge Shouming, institute Belong to album, deliver time, total duration, sample audio label etc..Wherein, the sample audio label can be Art Rock, friend Gram, different types of style of song, the sample audio data such as heavy metal, Summoning or folk song be a succession of non-semantic symbolic indication Opaque binary stream, that is, sample audio content, the sample frequency information and sample timbre information are sample The spectral characteristic (frequency domain characteristic of sample audio signal) of this audio.
Feature frequency response refers to generated sound when the sample audio signal that one is exported with constant voltage is connected with system With the variation of frequency and there is a phenomenon where increasing or decaying, this acoustic pressure variation relation curve associated with frequency is known as pressure Feature frequency response curve, as shown in figure 3, abscissa is frequency, ordinate is sound pressure level.In the specific implementation, due to human ear audition Frequency range is 20Hz to 20kHz, therefore the sample audio of 20Hz~20KHz can be acquired by sample information acquiring unit 14 Afterwards, and the spectral characteristic in sample audio in suitable frequency range (such as 50Hz~20kHz) is extracted, it is special according to the frequency spectrum extracted Property draws the feature frequency response curve of the sample audio.
Sample parameter acquiring unit 15, for based on the feature frequency response curve, the sample frequency information and described Sample timbre information obtains the digital equalising processing curve of sample audio and the reverberation parameters of sample audio；
It is understood that the principle of digital equalising processing is：Input signal " X " is established into corresponding output signal " Y ", Y =f (X) includes the function of one and " X " respective frequencies " k " again wherein in this action type of f ().The function of " X " will be corresponded to Expression formula expansion i.e. Y=g (k) * X, wherein g () change with digital equalising parameter regulation.In embodiments of the present invention, The input signal " X " is sample frequency information, the sample timbre information and feature frequency response curve, the frequency " k " For the corresponding frequency values of the feature frequency response curve.Based on above-mentioned handling principle, produces digital equalising and handle curve.Such as Fig. 4 It is shown a kind of digital equalising processing curve, abscissa is frequency, and ordinate is digital equalising parameter, the digital equalising processing Curve is change curve of the digital equalising parameter with frequency.
Meanwhile it being based on the feature frequency response curve, the sample frequency information and the sample timbre information, it can be obtained The reverberation parameters of sample audio.Wherein, the generation of reverberation is since a sound producing body is after sending out sound wave, and sound wave is via sky The surface that gas touches barrier will be reflected, and due to the complexity of actual environment, result in the sound that a source of sound is sent out Sound will produce various echo from all directions, after these sound mix, be formed so-called reverberation.Reverberation First sound is " direct sound wave ", that is, source sound, and dry voice output is called in effect device, is to send out direct arrival from sound The sound of audience's ear and the chief component of sound pressure level.The propagation attenuation of sound pressure level and distance square are inversely proportional, i.e., Distance doubles, and sound pressure level reduces 6dB.Subsequent several apparent sound being separated by out are called " early reflected sound ", again Claim nearly secondary reflection sound, is that the sound that sends out of sound source is reached after ambient interfaces (wall and ceiling, ground) reflect 1~2 time and listened The sound of many ears, the reflected sound reached within 50ms more late than direct sound wave belong to this range, and sound is bigger, brighter It is aobvious, it can reflect source sound in space, ear and distance relation between the walls.The characteristics of reflection is that ear can not It and direct sound wave are distinguished, can only be superimposed them impression.Therefore reflection is to improving sound pressure level harmony The clarity of sound is beneficial.Its propagation attenuation is related with the sound absorption characteristics of reflecting interface.The last one sound is " reverberation sound ", is The multiple reflections sound to 50ms or more more late than direct sound wave.For music, though reverberation sound can increase the richness of music, it But the clarity that sound can be reduced while increasing fullness can make sound send out " dry " when too small, can not be excessive.Reverberation The size of sound and the sound absorption characteristics of ambient interfaces are directly related.
The reverberation parameters may include reverrberation intensity, reverberation time, nephelometric turbidity unit and reverberation density etc..Wherein, reverberation The time uninteresting hair shaft of short sound, long sound is again confused to lose a large amount of details, and the suitable reverberation time can not only beautify Sound covers musical instrument noise, and musical sound fusion can also be made to increase the continuity of loudness and syllable.It should be noted that a sample This audio corresponds to a reverberation parameters.
Sample parameter adjustment unit 16, the sample audio label for obtaining the sample audio, based on equal loudness contour with And the sample audio label, the octave characteristic point handled in curve in selected frequency range the digital equalising are adjusted It is whole, to obtain the corresponding digital equalising parameter of each octave characteristic point；
Specifically, the sample audio label may include that rock and roll, metal music, folk song and disco etc. are different types of Style of song, and may include at least one sample audio label per class sample audio label, as sample audio label " rock and roll " can be with Including " Art Rock, punk, Post rock, stone roller core etc. " sample audio label.The sample sound for obtaining the sample audio Criterion label, it is to be understood that the sample audio label for obtaining sample audio, based on sample audio label as shown in Figure 2 with The correspondence of sample audio label, you can get the sample audio label of sample audio.For example, sample audio is " grey aunt Ma ", the sample audio label of " Cinderella " they are " popular metal ", then table look-up 2 it is found that " popular metal " belongs to " metal music ", Therefore, the sample audio label of " Cinderella " is " metal music ".
The equal loudness contour be description etc. ring under the conditions of sound pressure level and frequency of sound wave relation curve, be aural signature it One.Pure tone i.e. at different frequencies needs which kind of sound pressure level reached, and could obtain consistent hearing loudness for hearer.Such as Fig. 5 show a kind of pure tone equal loudness contour figure, and abscissa is frequency, and ordinate is sound pressure level.Acoustic pressure is that atmospheric pressure is disturbed The variation generated afterwards, the i.e. overbottom pressure of atmospheric pressure, it is equivalent to pressure change caused by being superimposed a disturbance on atmospheric pressure. Sound pressure level indicates that unit dB is defined as the ratio of acoustic pressure virtual value p (e) to be measured and reference sound pressure p (ref) with symbol SPL Value takes common logarithm, multiplied by with 20.The sound pressure level of different frequency in figure corresponding to every curve is different, but human ear sense The loudness felt is the same, and every curve indicates the variation relation of different loudness side's lower frequencies and sound pressure level.By equal loudness contour It is known that when loudness is smaller, human ear is insensitive to high bass perception for race, and when loudness is larger, high bass perception is gradually clever It is quick.
The digital equalising parameter is exactly to adjust the yield value of signal after the signal of each frequency range in digital equalising processing curve, The digital equalising parameter is corresponded with each octave characteristic point.Wherein, the octave characteristic point, as by discrete frequency Spectrum is divided into frequency range one by one, and so that the upper limiting frequency of each frequency range is doubled than lower frequency limit, (namely frequency is 2:1 frequency The frequency band at interval), to obtain multiple octaves, then characteristic point is taken in each octave respectively.If for example, signal frequency Ranging from 63Hz~16kHz, can be divided into 8 octaves, and respectively 63Hz~126Hz, 126Hz~252Hz, 252Hz~ 504Hz, 504Hz~1.08kHz, 1.008kHz~2.016kHz, 2.016kHz~4.032kHz, 4.032kHz~8.064kHz And 8.064Hz~16kHz, characteristic point then is taken in each octave, it, then will each again if 1/24 octave characteristic point Sound interval is divided into 24 frequency ranges, a 1/24 octave characteristic point of each frequency range as the octave, each 1/24 octave Characteristic point corresponds to a digital balance parameters, is adjusted to the corresponding digital equalising parameter of each 1/24 octave characteristic point, So that it is determined that a suitable parameter area.
In the specific implementation, sample parameter adjustment unit 16 selectes the song of partial frequency range in digital equalising processing curve Selected curve is divided into octave one by one, is then based on the parameter information of equal loudness contour in each octave by line Characteristic point is adjusted, and ensures that the digital equalising parameter of each octave characteristic point is in sample audio during the adjustment Variation in parameter area indicated by label, so that it is determined that the digital equalising parameter area of each octave characteristic point.For example, right Curve in digital equalising processing curve shown in Fig. 4 within the scope of 63Hz~16kHz is divided into 8 octaves, then to each times Sound interval takes characteristic point, obtains discrete octave characteristic point as shown in FIG. 6, then corresponding commonly used digital based on sample audio label Balance parameters are adjusted the digital equalising parameter of each discrete octave characteristic point, to determine under the sample audio label Each octave takes the digital equalising parameter area of characteristic point.
