Detailed Description
The present invention will be described in further detail with reference to the attached drawings, and it should be understood 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.
Example 1:
fig. 1 is a schematic process diagram of an audio processing method according to an embodiment of the present invention, where the process includes the following steps:
s101: a target audio is received.
In order to make the auditory sense of music less boring and realize dynamic tuning of a music equalizer, in the embodiment of the invention, different adjustment values are adopted to perform audio tuning processing on sounds with the same frequency at different preset moments.
Specifically, a target audio to be processed is first acquired. Since most of the current music is mixed sound, the music at each moment contains different sounds, and the frequency of each sound is different. In order to better process the audio, the frequency of each sound of the target audio at each preset time needs to be acquired, where the preset time may be preset, and when the preset time is set, the time intervals between any two preset times may be equal or unequal, and may be specifically and flexibly set according to the processing requirement.
S102: and adjusting the sound intensity of the sound with the same frequency in the target audio by adopting different adjusting values at different preset moments.
After each sound at each preset time of the target audio is acquired, the frequency of each sound is determined. Aiming at the sound with the same frequency in the target audio, different adjusting values are adopted at different preset moments to adjust the sound intensity of the sound.
For example, the frequency of a certain sound among the frequencies of the sounds at the first preset time is 68Hz, and the sound intensity of the sound at the frequency is adjusted according to the currently stored adjustment value, and then the currently stored adjustment value is updated so that the updated adjustment value is different from the adjustment value before updating. If the frequency of the sound at the third preset moment still exists at the frequency of 68Hz, the sound intensity of the sound at the frequency is adjusted according to the stored updated adjustment value, and after the adjustment, the currently stored adjustment value corresponding to the frequency is updated.
After the sound intensity adjustment value of the sound of each frequency at each preset time is determined, the corresponding information is stored in the music equalizer corresponding to the target audio, so that the music equalizer can adjust the sound intensity of the sound of each frequency at each preset time in the process of playing the target audio by adopting the corresponding adjustment value. For example, the adjustment value of the sound of 400Hz at a certain preset time is-4 dB, and when the adjustment is performed, the sound intensity of the sound of 400Hz is reduced by 4dB at the preset time by the music equalizer.
According to the embodiment of the invention, aiming at the sound with the same frequency in the target audio, different adjustment values are adopted for adjustment at different preset moments, so that compared with the prior art in which a fixed adjustment value is adopted at each preset moment, the effect of dynamic tuning is achieved, and the music auditory experience of a user is improved.
Example 2:
in order to improve the efficiency of audio processing, on the basis of the foregoing embodiment, in an embodiment of the present invention, before adjusting the sound intensity of the sound with different adjustment values at different preset times for the sound with the same frequency in the target audio, the method further includes:
judging whether the frequency is a preset target frequency or not according to each frequency in the target audio;
if yes, the subsequent steps are carried out.
If not, the sound intensity of the sound of the frequency is not adjusted.
In order to adjust the sound of the frequency to be adjusted in a targeted manner, and further improve the efficiency of audio processing, in the embodiment of the present invention, a target frequency is preset, and the target frequency may be one or more, and generally more.
After each frequency at a preset moment in the target audio is identified, whether the frequency is the target frequency or not is judged for each frequency, specifically, whether the frequency is a preset certain target frequency or not is judged, whether the difference value between the frequency and the preset certain target frequency is within a preset range or not is judged, if the frequency is the preset certain target frequency or the difference value between the frequency and the preset certain target frequency is within the preset range, the frequency can be judged to be the target frequency, and the sound intensity of the sound of the frequency is adjusted.
And if the frequency is judged not to be the target frequency, the sound intensity of the sound of the frequency is not adjusted.
As shown in fig. 2, for a schematic diagram of a music equalizer provided in an embodiment of the present invention, target frequencies of the music equalizer are 68Hz, 165Hz, 400Hz, 972Hz, 2kHz, 6kHz, and 14kHz, respectively, when the music equalizer is used to tune target audio, it is explained that the music equalizer can adjust sound intensities of sounds of these frequencies, and when adjusting, an adjustment value of each target frequency determined according to each preset time is adjusted.
In the embodiment of the invention, the target frequency is preset, and only the audio corresponding to the target frequency is adjusted during audio processing, so that the audio processing efficiency is improved.
Example 3:
in order to achieve a better audio processing effect, on the basis of the above embodiments, in an embodiment of the present invention, adjusting the sound intensity of the sound with different adjustment values at different preset times for the sound with the same frequency in the target audio includes:
the method comprises the steps of determining a first target adjustment mode adopted at the last preset time aiming at least two preset adjustment modes, taking the next adjustment mode of the first target adjustment mode as a target adjustment mode corresponding to the current preset time according to the preset circulation sequence of each adjustment mode, and adjusting the sound intensity of the sound according to the adjustment value corresponding to the sound of the frequency in the target adjustment mode, wherein the adjustment value of each adjustment mode aiming at the sound of the same frequency is different.
In order to achieve a better audio processing effect, in the embodiment of the present invention, at least two adjustment modes are preset for a target audio, and an order in which each adjustment mode is cyclically used is predetermined, for example, 5 adjustment modes may be preset, which are: adjustment mode 1, adjustment mode 2, adjustment mode 3, adjustment mode 4, and the predetermined order of being used cyclically is: adjustment mode 1, adjustment mode 2, adjustment mode 3, and adjustment mode 4.
If the adjustment mode 1 is used for the sound at the first preset time, the adjustment mode 2, the adjustment mode 3 and the adjustment mode 4 are used for the sound at the second preset time, the third preset time and the fourth preset time in sequence. And according to the preset cycle sequence of the adjustment mode, the adjustment mode 1 is continuously used for the sound at the fifth preset time, and each adjustment mode is used at each preset time according to the cycle sequence in turn, so that the adjustment of the sound is realized.
When the target audio is tuned, aiming at each preset time of the target audio, determining an adjustment mode adopted at the last preset time of the preset time, and determining the adjustment mode as a first target adjustment mode. And determining the next adjusting mode of the first target adjusting mode according to the preset circulating sequence of each adjusting mode, and taking the adjusting mode as the target adjusting mode corresponding to the preset moment. And adjusting the sound intensity of the sound at the preset moment by adopting the determined target adjustment mode. For example, if the first target adjustment mode corresponding to the previous preset time of the preset time is the adjustment mode 1, it can be known that the target adjustment mode corresponding to the preset time is the adjustment mode 2 according to the set circulation rule.
If the preset time is the first preset time of the target audio, one of the adjustment modes used in the loop is arbitrarily selected as the target adjustment mode, and preferably, the adjustment mode ranked as the first bit may be determined as the target adjustment mode.
The above-described method for determining the target adjustment mode in the loop method will be described in detail with reference to table 1.
TABLE 1
In tuning the target audio, five adjustment modes as shown in table 1 may be cyclically employed. According to the description of table 1, the preset target frequencies include: 68Hz, 165Hz, 400Hz, 972Hz, 2kHz, 6kHz and 14 kHz.
In order to reduce the complexity of audio adjustment, the target frequency can be divided into three ranges, namely a low range, a middle range and a high range according to the corresponding relationship between the ranges and the frequencies, wherein the low range comprises target frequencies of 68Hz, 165Hz and 400 Hz; the midrange region includes target frequencies of 972Hz and 2 kHz; the treble region includes target frequencies of 6kHz, 14 kHz. The sound intensity of the sound corresponding to the target frequency for each vocal range can be adjusted by using five adjustment modes, wherein each adjustment mode has a different adjustment value for the sound intensity of the sound of the same target frequency, for example, for each target frequency in a bass range, the five adjustment modes are respectively floating within an attenuated range (-12dB to 0dB), directly floating within an attenuated range and an enhanced range (-6dB to 6dB), floating within an enhanced range (0dB to 12dB), and floating within a range between the lowest range and the highest range (12 dB to 12dB), and floating within a range specified by a user.
After the target adjustment mode is determined, the sound intensity of the sound at the target frequency may be adjusted directly according to the adjustment value stored in the target adjustment mode, for example, if the target adjustment mode is adjustment mode 1, and if the frequency of the sound at the preset time is 165Hz, the sound intensity of the sound at the frequency may be adjusted in a manner of floating within the attenuation range (-12dB to 0 dB). Specifically, a value is randomly selected within the attenuated range (-12dB to 0dB) and used as the adjustment value for the frequency, such as-4 dB. And adjusting the sound intensity of the sound with the preset time and the frequency by adopting the adjusting value.
If the target adjustment mode is adjustment mode 2 and the frequency of the sound at the preset time is 165Hz, the sound intensity of the sound at the frequency can be adjusted in such a manner as to directly float (-6dB to 6dB) within the range of attenuation and enhancement. Such as randomly selecting a value within the de-emphasis and enhancement range (-6dB to 6dB) as the adjustment value for the frequency, such as +2dB or-2 dB. And adjusting the sound intensity of the sound with the frequency at the preset moment by adopting the adjusting value.
If the target adjustment mode is adjustment mode 3 and the frequency of the sound at the preset moment is 165Hz, the sound intensity of the sound at the frequency can be adjusted in a floating (0 dB-12 dB) mode within the enhanced range; if the target mode is the adjustment mode 4, for the sound with the frequency of 165Hz, the sound intensity of the sound with the frequency can be adjusted in a mode of exaggerated floating (-12dB to 12dB) between the lowest range and the highest range; if the target mode is the adjustment mode 5, for the sound having the frequency of 165Hz, the sound intensity of the sound having the frequency may be adjusted in a manner of floating within the user-specified range.
In the embodiment of the invention, at least two tuning modes are preset, the target adjustment mode corresponding to the preset time is determined in a recycling mode, and the target adjustment mode is adopted to adjust the sound intensity of the sound at the preset time, so that the effect of dynamic tuning is realized.
Example 4:
in order to achieve a better audio processing effect, on the basis of the above embodiments, in an embodiment of the present invention, adjusting the sound intensity of the sound with different adjustment values at different preset times for the sound with the same frequency in the target audio includes:
determining a target sound zone corresponding to the frequency of each sound at the preset moment according to a preset frequency range corresponding to each sound zone, and determining the sound intensity of the corresponding target sound zone according to the sound intensity of the sound at each frequency;
and aiming at each frequency, determining a target adjustment value after the frequency is updated on the basis of the current corresponding adjustment value of the frequency according to the relation between the sound intensity of the target sound zone and the sound intensities of other target sound zones, and adjusting the sound intensity of the sound of the frequency according to the target adjustment value.
At present, when the sound zones are divided, a plurality of sound zones are divided according to the frequency of sound, in the embodiment of the invention, the sound zones comprise a bass zone, a midrange zone and a treble zone, and different sound frequency ranges are preset for different sound zones. Specifically, the sound having a frequency of 20Hz to 500Hz may be divided into a bass region, the sound having a frequency of 500Hz to 2kHz may be divided into a midrange region, and the sound having a frequency of 2kHz to 10kHz may be divided into a treble region.
After the frequency of each sound of the target audio at each preset time is identified, aiming at each preset time, according to the magnitude of the frequency of each sound at the preset time and the range of the frequency corresponding to each sound zone, determining a target sound zone corresponding to the frequency of each sound at the preset time. For example, the frequencies of the sound at a predetermined time include: and the three frequency values are matched with the frequency range value corresponding to each sound zone by 50Hz, 1kHz and 5kHz, so that a bass zone corresponding to 50Hz, a middle sound zone corresponding to 1kHz and a treble zone corresponding to 5kHz in the sound at the preset moment can be determined.
In the embodiment of the present invention, in order to improve the tuning effect, for each frequency, the adjustment value of the frequency is determined according to the relationship between the sound intensity of the target zone corresponding to the frequency and the sound intensities of the other target zones.
Therefore, it is first required to determine the sound intensity of each target sound zone, because after the frequency of the sound at a certain preset time is determined, the corresponding target sound zone can be determined, and the number of the frequencies included in the same target sound zone at the same preset time may be different, if the frequency included in the target sound zone at the preset time is only one, the sound intensity of the sound at the frequency can be determined as the sound intensity of the target sound zone; if the target sound zone includes at least two frequencies at the preset time, the average value of the sound intensities of the sounds of the at least two frequencies may be used as the sound intensity of the target sound zone, or the maximum value, the minimum value, or any one of the sound intensities of the sounds of the at least two frequencies may be used as the sound intensity of the target sound zone.
Based on the above description, after the sound intensity of the target sound zone corresponding to each frequency is determined, for each frequency, according to the relationship between the sound intensity of the target sound zone corresponding to the frequency and the sound intensities of other target sound zones, the target adjustment value after the frequency update is determined on the basis of the adjustment value currently corresponding to the frequency. For example, if the sound intensity of the target sound zone corresponding to the frequency is respectively greater than the sound intensities of the other target sound zones, 2dB may be added as a target adjustment value based on the current adjustment value of the frequency, that is, if the current adjustment value is +2dB, the updated target adjustment value is +4dB, and the adjustment value corresponding to the currently stored frequency is updated by using the target adjustment value.
Because each frequency may have different sound intensities of the corresponding target sound zone and different relationships with the sound intensities of other target sound zones at different preset times, the target adjustment value of the frequency determined at different preset times is also different for each preset frequency.
Example 5:
in order to further improve the tuning effect, in the embodiments of the present invention, in addition to the above embodiments, the determining, for each frequency, the updated target adjustment value of the frequency based on the adjustment value currently corresponding to the frequency according to the relationship between the sound intensity of the target sound zone and the sound intensities of the other target sound zones includes:
acquiring the sound intensity of each target sound zone at the preset moment;
aiming at the target sound zone corresponding to each frequency, judging whether the sound intensity of the target sound zone is respectively greater than the sound intensity of each other target sound zone;
if so, increasing the current corresponding adjustment value of the frequency by a first preset decibel value, and taking the updated adjustment value as the target adjustment value of the frequency.
In the above embodiments, it is mentioned that, for each frequency, the adjustment value of the frequency is determined according to the relationship between the sound intensity of the target sound zone corresponding to the frequency and the sound intensities of other target sound zones, and in order to further improve the tuning effect, in the embodiments of the present invention, the determination process of the adjustment value is specifically described.
First, for each preset time, according to each frequency of the preset time, determining the sound intensity of each target sound zone at the preset time. And then, aiming at the target sound zone corresponding to each frequency at the preset moment, judging whether the sound intensity of the target sound zone corresponding to the frequency is respectively greater than the sound intensity of each other target sound zone. If yes, the sound of the frequency is considered to be more prominent at the preset moment, and the adjustment value corresponding to the frequency can be adjusted to enable the target audio to have better hearing effect.
In the embodiment of the present invention, for each frequency, a corresponding initial adjustment value is preset, and the initial adjustment values corresponding to different frequencies may be the same or different. If the sound intensity of the target sound zone corresponding to a certain frequency is respectively greater than the sound intensity of each of the other target sound zones, the adjustment value can be updated on the basis of the currently stored adjustment value, and the sound intensity of the sound with the frequency is adjusted by adopting the updated adjustment value. For example, a first preset decibel value may be added to the currently stored adjustment value. That is, if the currently stored adjustment value of the frequency is-6 dB, and the first preset decibel value is +2dB, the target adjustment value corresponding to the frequency is-4 dB.
In this embodiment of the present invention, if the sound intensity of the target sound zone corresponding to the frequency and the sound intensity of the second target sound zone are both less than the sound intensity of the third target sound zone, and the third target sound zone is a low sound zone, determining the updated target adjustment value of the frequency based on the current adjustment value corresponding to the frequency according to the relationship between the sound intensity of the target sound zone and the sound intensities of other target sound zones includes:
if the target sound zone corresponding to the frequency is a middle sound zone, increasing or decreasing the adjustment value corresponding to the frequency by a preset decibel value, and taking the updated adjustment value as the target adjustment value of the frequency;
if the target sound zone corresponding to the frequency is a high sound zone, the adjustment value corresponding to the frequency is reduced by a preset decibel value, and the updated adjustment value is used as the target adjustment value of the frequency.
After the sound intensity of the target sound zone corresponding to each frequency is determined, the relationship between the sound intensity of the target sound zone corresponding to the frequency and the sound intensities of other target sound zones is determined for each frequency, and if the sound intensity of the target sound zone corresponding to the frequency and the sound intensity of the second target sound zone are both less than the sound intensity of the third target sound zone and the third target sound zone is a low sound zone, when the target adjustment value corresponding to the frequency is determined, the relationship can be determined in the following manner.
If the target sound zone corresponding to the frequency is a midrange zone, since in the embodiment of the present invention, the corresponding initial adjustment value is set for the frequency in advance, when the target adjustment value of the frequency is determined, the adjustment value may be updated on the basis of the current preset initial adjustment value, and the updated adjustment value is used as the target adjustment value. For example, the preset initial adjustment value may be increased or decreased by a preset decibel value, and of course, the initial adjustment value may be kept unchanged. In order to ensure the audio tuning effect, each adjusting value is not more than +12 decibels at most and not less than-12 decibels at most.
