As shown in fig. 1, the memory 1005, which is a kind of computer storage medium, may include therein an operating system, a network communication module, a user interface module, and an audio adjustment program.
In the audio conditioning apparatus shown in fig. 1, the network interface 1004 is mainly used for connecting to a backend server and communicating data with the backend server; the user interface 1003 is mainly used for connecting a client (user side) and performing data communication with the client; and the processor 1001 may be configured to call the audio adaptation program stored in the memory 1005 and perform the following operations:

and adjusting the working mode of the target terminal according to the equipment noise, and adjusting the audio data based on the adjusted target terminal.
Referring to fig. 2, in an embodiment of the audio adjusting method, the audio adjusting method includes the following steps:
step S10, audio data in a preset time period are obtained, and the audio decibel level of the television is determined based on the audio data;
the embodiment is mainly applied to smart home, and the communication connection of each equipment in the smart home is established based on the internet of things technology, such as the communication connection between smart devices such as a smart television, a smart refrigerator, a smart juice extractor or a smart juice crusher, a smart floor sweeping robot and a smart dust collection robot. Therefore, in this embodiment, as shown in fig. 4, the smart television (an internet of things control device such as a smart speaker) includes an intelligent noise level identification scheduling module, an automatic enhanced speech dialog module, and an automatic audio dialog enhancement display module. The intelligent noise level identification scheduling module automatically adjusts the working mode of the intelligent equipment according to the low-frequency noise, the medium-frequency noise and the high-frequency noise of the environment. The intelligent television automatically adjusts the working modes of other intelligent devices in the current environment according to the noise dynamic state to reduce the noise, and adjusts the relevant volume of the intelligent television so as to improve the influence of the current environment noise on the operation of the intelligent television. Also, in the present embodiment, the noise is equivalent to the noise.
Therefore, in this embodiment, the smart television first determines whether the environmental noise decibel of the current environment is greater than a preset noise decibel (e.g., 30% of the average noise decibel), if the environmental noise decibel is greater than 30% of the average noise decibel, the smart television sets 1 identifier (1, identifier starts the noise level device), and the smart television starts the smart noise level identification scheduling module. At this time, audio data output by a television (i.e., a smart television) within a preset time period can be acquired, for example, the smart television acquires audio data of every 1 second of a wireless network television (the audio of the television itself) microphone unit time and stores the audio data into the memory 11, the smart television extracts the audio frequency and decibels of the memory 11 for 0.5 second and stores the audio frequency and decibels into the memory 12, and the smart television acquires the frequency and decibels (i.e., the audio data) of the memory 12 to determine the audio decibel level of the television. In the present embodiment, the audio decibel levels are preferably divided into 3, but not limited to these 3. If the audio frequency of the current program acquired by the smart television is less than 100Hz and the audio decibel is less than 35 decibels (i.e., the audio frequency and the decibel in the memory 12), the television can start a single low-frequency noise identification scheduling mode; if the audio frequency of the current program obtained by the smart television is greater than or equal to 100Hz but less than 300Hz, and the audio decibel is greater than or equal to 35 decibels but less than 60 decibels (i.e., the audio frequency and the decibels in the memory 12), the television can start a single medium frequency noise identification scheduling mode; if the audio frequency of the current program obtained by the smart tv is greater than or equal to 300Hz but less than 1500Hz, and the audio decibel is greater than or equal to 60 decibels but less than 120 decibels (i.e., the audio frequency and the decibels in the memory 12), the tv may start the single high frequency noise identification scheduling mode. The preset time period can be any time period set in advance by a user, and the audio data comprises the audio frequency and the audio decibel of the television. The audio decibel level may be a range of values of audio decibels.
Step S20, acquiring equipment noise generated by a target terminal corresponding to the television according to the audio decibel level;
in this embodiment, after the audio decibel level of the television is determined, the device noise generated by the target terminal corresponding to the television (i.e., the intelligent device connected to the television, such as an intelligent juice extractor, an intelligent floor-sweeping robot, an intelligent dust-collecting robot, etc.) can be directly obtained according to the audio decibel level. If the audio frequency of the television is less than 100Hz and the audio decibel is less than 35 decibels, the smart television acquires audio data of the intelligent juice extractor or the intelligent juice extractor at the highest gear which normally works per 1 second unit time, and stores the audio data into the memory 22. And acquiring audio data of the intelligent juice extractor or the intelligent juice extractor at the lowest gear which normally works per 1 second in unit time, storing the audio data into the memory 23, subtracting the audio frequency and the audio decibel at the lowest gear in the memory 23 from the audio frequency and the audio decibel at the highest gear in the memory 22 to obtain an audio frequency range and an audio decibel range of the intelligent juice extractor or the intelligent juice extractor, and storing the audio frequency range and the audio decibel range into the memory 24. The smart tv then acquires the frequency of the memory 12 and the frequency of the memory 44 to determine the number of times of the same frequency occurring every unit time of 0.5 seconds, counts 1 every 1 occurrence, accumulatively adds and saves in the memory 33, and determines that the audio data matches the equipment noise of the target terminal (i.e., the smart juicer or the smart shredder) when the number of times in the memory 33 is greater than 1.
When the audio frequency of the television is greater than or equal to 100Hz but less than 300Hz and the audio decibel is greater than or equal to 35 decibel but less than 60 decibel, the smart television acquires audio data of the intelligent floor sweeping robot at the highest gear in normal operation per unit time per 1 second and stores the audio data in the memory 42. And acquiring audio data of the intelligent floor-sweeping robot at the lowest gear in normal operation per 1 second per unit time, storing the audio data into the memory 43, subtracting the audio frequency and the audio decibel at the lowest gear in the memory 43 from the audio frequency and the audio decibel at the highest gear in the memory 42 to obtain an audio frequency range and an audio decibel range of the intelligent floor-sweeping robot, and storing the audio frequency range and the audio decibel range into the memory 44. The smart television then obtains the frequency of the memory 12 and the frequency of the memory 44 to determine the number of times of the same frequency occurring every unit time for 0.5 second, counts 1 every time of occurrence, accumulatively adds and saves in the memory 55, and when the number of times in the memory 55 is greater than 1, determines that the audio data matches the device noise of the target terminal (i.e., the intelligent sweeping robot).
When the audio frequency of the television is greater than or equal to 300Hz but less than 1500Hz, and the audio decibel is greater than or equal to 60 dB but less than 120 dB, the intelligent television acquires audio data of the intelligent dust collection robot at the highest working gear in unit time every 1 second, and stores the audio data into the memory 72. And acquiring audio data of the intelligent dust collection robot at the lowest gear which normally works per 1 second in unit time, storing the audio data into the memory 73, subtracting the audio frequency and the audio decibel of the lowest gear in the memory 73 from the audio frequency and the audio decibel of the highest gear in the memory 72 to obtain an audio frequency range and an audio decibel range of the intelligent dust collection robot, and storing the audio frequency range and the audio decibel range into the memory 74. Then the smart tv acquires the frequency of the memory 12 and the frequency of the memory 74 to determine the number of times of the same frequency occurring every unit time for 0.5 second, counts 1 every 1 occurrence, accumulatively adds and saves into the memory 88, and when the number of times in the memory 88 is greater than 1, determines that the audio data matches the device noise of the target terminal (i.e., the smart robot cleaner). It should be noted that, when there are multiple target terminals, the television acquires the device noise generated by the multiple target terminals meeting the audio decibel level requirement, and the same processing steps are adopted for each target terminal.
And S30, adjusting the working mode of the target terminal according to the equipment noise, and adjusting the audio data based on the adjusted target terminal.
When the audio data is judged to be matched with the equipment noise, the working mode of the target terminal can be adjusted. For example, when the target terminal is an intelligent juice extractor or an intelligent juice crusher and the number of times in the intelligent memory 33 is greater than 1, the working mode of the intelligent juice extractor or the intelligent juice crusher is obtained, and the working mode is adjusted, for example, the gear of the intelligent juice extractor or the intelligent juice crusher is lowered by one gear, the gear for executing the operation of the intelligent juice extractor or the intelligent juice crusher is set, and the identifier 1 is stored in the memory 34. When the target terminal is the intelligent sweeping robot and the number of times in the intelligent storage 55 is greater than 1, the working mode of the intelligent sweeping robot is obtained, and the working mode is adjusted, for example, the gear of the intelligent sweeping robot is lowered by one gear, and the gear for executing the work of the intelligent sweeping robot is set, and the identifier 1 is stored in the storage 66. When the target terminal is the intelligent dust collection robot and the number of times in the intelligent storage 88 is greater than 1, the working mode of the intelligent dust collection robot is obtained, and the working mode is adjusted, for example, the gear of the intelligent dust collection robot is lowered by one gear, the gear for executing the work of the intelligent dust collection robot is set, and the identifier 1 is stored in the storage 99.
And acquiring the identifiers in the memory 34, the memory 66 and the memory 99, summing the identifiers, storing the summed identifiers in the memory 100, and when the sum of the identifiers in the memory 100 is greater than 1, determining that the smart television has started automatic voice dialogue, and then adjusting the audio data. That is, after it is determined that there is an adjustment to the operation mode of the target terminal, the audio data may be adjusted. The audio data may be adjusted by the way that the tv obtains the decibel of the average background audio (i.e., background audio decibel) of the tv microphone voice in 1 second per unit time and stores the decibel of the average white audio (i.e., white audio decibel) of the tv microphone voice in 1 second per unit time in the memory 111, and obtains the decibel of the microphone voice in 1 second per unit time and stores the decibel in the memory 222. The audio decibel in the memory 111 is added to the audio decibel in the memory 222 and divided by 2 to obtain an average audio decibel, the average audio decibel is stored in the memory 333, the background audio decibel in the memory 111 is divided by the average audio decibel in the memory 333 to obtain the ratio of the background audio decibel to the average audio decibel, and the ratio is stored in the memory 444. And when the proportion in the memory 444 is less than 50 percent, it can be determined that the contrast of the background sound is small, and the background sound does not need to be enhanced, so that the background sound field can be started to increase the contrast mode, that is, the television acquires the audio of the played audio contrast part, the gain is increased by 1 time of average audio decibel, and after the gain of the contrast audio increased by 1 time is completed, the identifier 1 is set and stored in the memory 555. If the proportion in the memory 444 is more than 50 percent, it is determined that the contrast of the background sound of the television is mainly human, and the background sound is large and needs to be enhanced, so the background sound action field can be started to increase the contrast mode, that is, the television acquires the audio of the played audio contrast part, the gain is increased by 2 times of average audio decibels, acquires the audio of the played audio background part, the gain is increased by more than 1 time, and after the contrast audio gain increased by 2 times and the background audio is increased, the setting identifier 1 is stored in the memory 666. And displays the distribution in memory 555 or memory 66 in the screen of the television.
In the embodiment, audio data of a television in a preset time period is obtained, and the audio decibel level of the television is determined based on the audio data; acquiring equipment noise generated by a target terminal corresponding to the television according to the audio decibel level; and adjusting the working mode of the target terminal according to the equipment noise, and adjusting the audio data based on the adjusted target terminal. The equipment noise is determined by obtaining the audio decibel level of the television, the working mode of the target terminal is adjusted according to the equipment noise, and the audio data is adjusted, so that the phenomenon that a user needs to manually adjust the sound of the television when the noise exists in the prior art is avoided, the volume of the television can be automatically adjusted according to the noise, and the influence of the noise on the normal operation of the television is avoided.
Further, on the basis of the first embodiment of the present invention, a second embodiment of the audio adjusting method of the present invention is further provided, and this embodiment is step S30 of the first embodiment of the present invention, and a refinement of the step of adjusting the operating mode of the target terminal according to the device noise includes:
step x, detecting whether the audio data is matched with a target noise in the equipment noise;
in the present embodiment, the audio data includes a plurality of audio frequencies, and the device noise also includes a plurality of noise frequencies. Therefore, after the device noise generated by the target terminal and the audio data output by the television are acquired, the audio frequency and the noise frequency acquired in the same time period need to be compared, if the audio frequency and the noise frequency are the same in a certain time period, the noise frequency can be taken as the target frequency, and the noise corresponding to the target frequency is taken as the target noise, so that the matching between the audio data and the target noise in the device noise can be determined.
And y, if the target terminal is matched with the target terminal, adjusting the working mode of the target terminal.
When the audio data is found to be matched with the target noise in the device noise through judgment, the number of the target terminals needs to be determined, and if only one target terminal is needed, the working mode of the target terminal can be directly adjusted, such as gear down-regulation and other operations. However, if there are a plurality of target terminals, it is necessary to determine a terminal that generates target noise and adjust an operation mode of the terminal. However, when the audio data is not matched with the target noise in the device noise, the corresponding prompt message is output to remind the user that the audio data cannot be automatically adjusted.
In the embodiment, when the audio data is matched with the target noise in the device noise, the working mode of the target terminal is adjusted, so that the normal output of the audio data of the television is ensured.
Further, the step of adjusting the audio data based on the adjusted target terminal includes:
step a, acquiring the noise of target equipment generated by an adjusted target terminal, and detecting whether the noise of the target equipment is less than a preset value;
in this embodiment, after the operating mode of the target terminal is adjusted (e.g., the gear mode of the target terminal is adjusted), noise generated by the adjusted target terminal, that is, target device noise is obtained, and whether the adjusted noise affects normal operation of the television is detected, that is, whether the target device noise is smaller than a preset value (which may be any value set in advance by a user) is detected, and different operations are performed according to different detection results.
And b, if so, acquiring an audio decibel proportion occupied by the background audio decibels in the audio data, and adjusting the audio data according to the audio decibel proportion.
And when the noise of the target equipment is found to be smaller than the preset value through judgment, the background audio decibel and the dialogue audio decibel in the audio data can be obtained, the audio decibel proportion occupied by the background audio decibel in the audio data is calculated, and then the audio data is adjusted according to the audio decibel proportion. Wherein the audio data comprises a background audio decibel and a dialogue audio decibel. The background audio decibels may be the decibels of the average background audio of the television microphone per unit time of 1 second in the television. The decibel to white audio may be the average decibel to white audio per unit time of 1 second for a microphone voice in a television. However, if the noise of the target device is greater than or equal to the preset value, it may be determined that the noise of the target terminal still affects the normal operation of the television, and the operation mode of the target terminal needs to be continuously adjusted until the new noise of the target device is greater than or equal to the preset value.
In this embodiment, when the target device noise generated by the other device is smaller than the preset value, the audio data is adjusted according to the audio decibel ratio, so that the accuracy of adjusting the audio data is ensured.
Specifically, the step of obtaining an audio decibel ratio occupied by the background audio decibels in the audio data includes:
step c, acquiring a background audio decibel and a dialogue audio decibel in the audio data, and calculating an average audio decibel according to the background audio decibel and the dialogue audio decibel;
in this embodiment, it is necessary to obtain a background audio decibel and a white audio decibel in the audio data, respectively, then calculate a sum of the background audio decibel and the white audio decibel, divide the sum by 2 to obtain an average value, and use the average value as the average audio decibel.
And d, calculating the proportion between the background audio decibel and the average audio decibel, and taking the proportion as the audio decibel proportion.
After the average audio decibel is obtained through calculation, the proportion between the background audio decibel and the average audio decibel can be calculated, and the proportion is used as the audio decibel proportion to determine the proportion occupied by the background audio decibel in the whole audio data, so that whether enhancement processing needs to be carried out on the background audio is determined.
In this embodiment, the average audio decibel is calculated according to the background audio decibel and the dialogue audio decibel in the audio data, and then the ratio of the background audio decibel to the average audio decibel is calculated and taken as the audio decibel ratio, so that the accuracy of calculating the audio decibel ratio is guaranteed.
Specifically, the step of adjusting the audio data according to the audio decibel ratio includes:
step e, if the audio decibel proportion is smaller than a preset proportion, enhancing the white audio decibel in the audio data;
after the audio decibel ratio is calculated, it is further required to detect whether the audio decibel ratio is smaller than a preset ratio (i.e., an arbitrary ratio value, such as 50%, set by the user in advance). If the audio decibel ratio is smaller than the preset ratio, enhancement processing can be performed on the white audio decibels in the audio data, for example, the white audio decibels are subjected to audio decibels with gain increased by 1 time of average. Note that no enhancement is performed on the background audio decibels at this time.
And f, if the audio decibel ratio is greater than or equal to a preset ratio, respectively enhancing the white audio decibels and the background audio decibels in the audio data.
When the audio decibel ratio is greater than or equal to the preset ratio, the white audio decibel and the background audio decibel in the audio data need to be enhanced respectively. If the television acquires the audio of the dialog part of the played audio (namely, the dialog audio decibels), the gain is increased by 2 times of average audio decibels, and acquires the audio of the background part of the played audio (namely, the background audio decibels), and the gain is increased by more than 1 time.
In this embodiment, the white audio decibels are enhanced when the audio decibel ratio is smaller than the preset ratio, and the white audio decibels and the background audio decibels are enhanced when the audio decibel ratio is greater than or equal to the preset ratio, so that the accuracy of adjusting the audio data is ensured.
Further, the step of obtaining the device noise generated by the target terminal corresponding to the television according to the audio decibel level includes:
step g, determining the noise level generated by a target terminal corresponding to the television according to the audio decibel level;
