Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, fig. 1 is a schematic flow chart of a method for implementing a vibration effect in an embodiment, where the method for implementing a vibration effect includes the steps of:
In particular, preferences that may be entered by a user may be displayed on a display interface of the device and used to adjust the vibration effects presented by the audio to be processed. Of course, the user may not be able to fully specify all his preferences at the beginning of the selection of the preferences, and thus only a portion of the preferences are selectively entered. The corresponding preference quantization value is obtained by performing quantization processing on the preference selection input by the user, and the quantization processing is to unify indexes of different units or orders of magnitude in the same numerical value range, so that the indexes can be conveniently weighted or compared and the like. And a default preference quantification value or a last preference quantification value of the user is selected for the remaining preference selections. It will be appreciated that if the user is not satisfied with the vibration effect ultimately presented by the device, the process may be returned to re-modify the preference until the user is satisfied with the vibration effect.
In a particular embodiment, the preference selection requiring input includes at least one of a scene preference selection, a music preference selection, a long short duration preference selection, and an extreme preference selection. The scene preference selection is the selection of a user for a specific scene applied when the device vibrates, and specifically may include the selection of scenes such as games, ringtones, videos, songs, and the like. The selection of the song preference is the selection of the audio style by the user, and particularly can comprise the selection of the styles of balladry, rap, pop, electric voice and the like. The long and short vibration preference selection is the preference of a user on the vibration type in the finally and integrally presented vibration effect, the long and short vibration preference selection can be a range value, when the long and short vibration preference value is larger, the part which is expected to be occupied by long vibration is more, and when the long and short vibration preference value is smaller, the part which is expected to be occupied by short vibration is more. The extreme preference selection is a selection that the user desires the vibration effect to be all long vibrations, or desires the vibration effect to be all short vibrations.
There is a particular quantization relationship between the preference selection and the preference quantization value from which the preference selection can be converted to a corresponding preference quantization value.
See table 1:
as shown in table 1, the device stores a preset target quantization relationship for each preference selection, and when any one of the preference selections is subjected to quantization processing, a corresponding preference quantization value can be obtained from the table. In the present embodiment, when the scene preference is selected as "game" or "ring", the scene preference quantization value is 0, and when the scene preference is selected as "video" or "song", the scene preference quantization value is 1; when the preference of the song is selected as slow rhythm song wind such as 'balladry', the preference quantized value of the song wind is small, and when the preference of the song wind is selected as fast rhythm song wind such as 'rap', the preference quantized value of the song wind is large; when the long and short ringing preference selection and the extreme preference selection are a certain input value between 0 and 1, the corresponding long and short ringing preference quantized value and extreme preference quantized value are also the same this input value. Other forms may also exist for setting the quantization relationship, for example, the selection of the long and short ringing preference may be 5 levels from 1 to 5, each level has a corresponding long and short ringing preference quantization value, and of course, other forms are also possible, and no specific limitation is made here.
And 104, identifying the prelude type and the beat type of the audio to be processed, quantizing the prelude type to obtain a prelude quantized value corresponding to the prelude type, and quantizing the beat type to obtain a beat quantized value corresponding to the beat type.

The feature recognition algorithm used in this section belongs to the existing algorithms, and therefore, will not be described in detail. Referring to fig. 2, fig. 2 is a schematic diagram of audio to be processed in an embodiment, and the prelude part, the non-rephotograph, the secondary rephotograph and the rephotograph are shown in fig. 2.
As well as the specific quantization relationship between the preference selection and the preference quantization value, the specific quantization relationship also exists between the prelude type and the prelude quantization value of each melody point, and the specific quantization relationship also exists between the beat type and the beat quantization value of each melody point.
See table 2:
as shown in table 2, the melody point belonging to the "non-prelude" has a prelude quantization value of 0, and the melody point belonging to the "prelude" has a prelude quantization value of 1. The beat quantization value of the melody point belonging to the "non-rephotography" is 0, the beat quantization value of the melody point belonging to the "next rephotography" is 0.5, and the beat quantization value of the melody point belonging to the "rephotography" is 1. Also, the above quantization relationship is taken as an example form, and the present embodiment includes, but is not limited to, the above quantization relationship.
And 106, carrying out quantitative calculation on the preference quantitative value, the prelude quantitative value and the beat quantitative value to obtain an effect type quantitative value of the audio to be processed.
In one embodiment, the quantization calculation process is: firstly, determining a weighted quantization value in the curved wind preference quantization value and the long and short vibration preference quantization value. Those belonging to the weighted quantization values can be used for subsequent quantization calculations, while those not belonging to the weighted quantization values do not have to participate in the subsequent quantization calculations. And then, carrying out quantitative calculation on the weighted quantitative value, the extreme preference quantitative value, the prelude quantitative value and the beat quantitative value through a preset quantitative calculation formula to obtain an effect type quantitative value P. Illustratively, the quantization calculation formula is specifically:
wherein alpha is1To the scene preference quantization value, α2For the quantized value of the camber preference, alpha3For the long and short ringing preference quantization value, alpha4For extreme preference of the quantized value, β1To quantify the value of the prelude, beta2For beat quantization value, m1、m2、m3、m4And m5Is a preset coefficient. Preferably, m is1Has a value of 3, m2Has a value of 0.99, m3Has a value of 2, m4Has a value of 3.01, m5The value of (2).
Referring to fig. 3, fig. 3 is a flow chart illustrating quantization calculation in one embodiment. Illustratively, the scene preference quantization value α1Is 0, the quantization value of the prelude beta1When 0, the weighted quantization value comprises a curvature preference quantization value alpha2And long and short vibration preference value alpha3. The effect type quantization value Pactual satisfies
This actually takes into account only the part in which the calculations are needed.
And 108, converting the effect type quantization value into an effect type value, acquiring a basic vibration signal corresponding to the audio to be processed, generating a target excitation signal according to the basic vibration signal and the effect type value, and exciting the equipment to vibrate by using the target excitation signal.
See table 3:
as shown in table 3, there is a specific quantization relationship between the effect type quantization value and the effect type value, and when the effect type quantization value is an input value between 0 and 1, the corresponding effect type value is the same input value. Also, the above quantization relationship is taken as an example form, and the present embodiment includes, but is not limited to, the above quantization relationship.
In one embodiment, a base vibration signal corresponding to the audio to be processed is retrieved from the effect library, wherein the melody points in the base vibration signal include a long vibration melody point and a short vibration melody point, see fig. 4 and 5, fig. 4 is a schematic diagram of the long vibration melody point in one embodiment, and fig. 5 is a schematic diagram of the short vibration melody point in one embodiment. It can be seen that the long vibration melody point also has a tail, and the long vibration melody point and the short vibration melody point have a difference in vibration duration.
When α is shown in FIG. 3 and Table 34When 0 is taken, the effect type value is
Meanwhile, the method belongs to an extreme short vibration type value, and the time length of each long vibration melody point in the basic vibration signal is reduced so as to meet the time length requirement of the short vibration melody point; when alpha is4When taking 1, the effect type value is
In between, it means that there is no need to change the vibration type of the melody point in the audio to be processed; when alpha is4When taking 2, the effect type value is
Meanwhile, the method belongs to an extreme long vibration type value, and the time length of each short vibration melody point in the basic vibration signal is increased so as to meet the time length requirement of the long vibration melody point.
Further, the effect type value determines the degree of adjustment of the vibration time length in addition to determining whether to change the vibration type of the melody point. Illustratively, the value [0, 1 ] may be taken]Mapping to the adjustment degree of 0-200%, when the effect type value is

The vibration time period T of the original melody point is adjusted to 1.5T. Similar vibration duration adjustment is also performed for the remaining melody points in the base vibration signal, thereby generating the target excitation signal.
