With the development of intelligent terminal technology, various devices with intelligent large screens enter thousands of households due to intelligence and convenience. The display technology of the intelligent large-screen device is still continuously improved at present, higher-quality film watching experience can be provided for users, but the picture display only affects one aspect of the film watching experience of the users, and besides, the sound playing technology of the intelligent large-screen device is also particularly important. The traditional intelligent large-screen equipment often has the condition of sudden change of volume when a user switches a program source, and the noise generated by sudden increase of the volume easily causes the damage of a loudspeaker, so that the technical problem that the adjusting capacity of the traditional intelligent large-screen equipment is poor when audio is switched is caused.

Referring to fig. 2, fig. 2 is a flowchart illustrating a first embodiment of an audio adjusting method.
A first embodiment of the present invention provides an audio adjusting method, which is applied to a master device, and includes:
step S10, acquiring frequency spectrum information of a target audio frequency, and setting a first audio frequency adjusting parameter of the target audio frequency according to the frequency spectrum information;
in this embodiment, the method is applied to an intelligent terminal having an audio playing function or being externally connected with an audio playing device, such as an intelligent television, a personal computer, a tablet, an intelligent washing machine, and the like. The target audio refers to the audio to be played. It should be noted that, when the intelligent terminal not in the working state is switched to the working state and a certain channel is selected to play, the audio of the program played by the channel is selected, or an audio application is selected to play the audio, or a media video application is selected to play the video, and the audio corresponding to the video is the target audio; and the audio corresponding to the played media file is also the target audio after the switching when the channels, the audio applications and the media video applications are switched at will. The spectrum information may specifically include information related to high and low frequency volume distributions, and the first audio adjustment parameter refers to an audio adjustment parameter derived based on the spectrum information of the target audio, and the audio adjustment parameter may specifically adjust the volume, the high and low frequency volume gains, and the like of the target audio.
Specifically, taking the smart television as an example, if the current user watches programs through the smart television at home, the user clicks to switch channels by using the remote controller, that is, an audio switching instruction is sent to the smart television. The smart television receives the audio switching instruction sent by the user currently, determines the program name of the next channel to be played according to the instruction, and then obtains the frequency spectrum information of the corresponding media file according to the program name so as to calculate the first audio adjusting parameter based on the frequency spectrum information.
Step S20, acquiring the number of audio playing devices, and obtaining a second audio adjusting parameter based on the number of audio playing devices and the first audio adjusting parameter;
in this embodiment, the number of the audio playing devices may specifically refer to the number of devices for playing audio that are built in the intelligent terminal, may also refer to the number of devices for playing audio that are externally connected to the intelligent terminal, or may refer to the number of devices for playing audio that are built in and externally connected to the intelligent terminal. Wherein, when intelligent terminal is intelligent TV, the equipment that is used for playing the audio frequency is the stereo set usually. The second audio adjusting parameter refers to the audio adjusting parameter obtained by adjusting the number of the audio playing devices according to the first audio adjusting parameter.
Specifically, smart electronics is still exemplified. If the smart television detects that the number of the current audio playing devices is 3, the first audio adjusting parameters can be distributed to the 3 audio playing devices in proportion, the specific proportion can be randomly set according to requirements, for example, when the 3 audio playing devices have no obvious difference, the first audio adjusting parameters are uniformly distributed to the audio playing devices in an equal proportion; when one of the 3 audio playing devices is a built-in device and the remaining two are external devices, the method is as follows 4: 3: 3, splitting the first audio adjusting parameter, distributing a plurality of parts to the built-in audio playing equipment, and distributing the rest two parts which are equal to each other to the external audio playing equipment.
And step S30, when the target audio is played, adjusting the target audio according to the second audio adjusting parameter.
In this embodiment, the intelligent terminal already obtains the second audio adjusting parameter before playing the target audio, and when the target audio is played, the intelligent terminal can directly adjust the target audio according to the second audio adjusting parameter, so as to avoid negative effects on a user or equipment due to too large volume or frequency change of the next audio.
Specifically, smart electronics is still exemplified. The user presses a channel switch key on the remote controller with the intention of switching from the current CCTV9 channel to the CCTV1 channel. The intelligent television acquires audio information of a weather forecast program currently played by the CCTV1, sets a first audio adjusting parameter based on the audio information, then acquires that the number of currently-connected audio playing devices is 2, divides the first audio adjusting parameter into half and half, takes half of the first audio adjusting parameter as a second audio adjusting parameter, and sends the second audio adjusting parameter to the connected audio playing devices so that the audio playing devices can adjust the target audio according to the second audio adjusting parameter when playing the target audio.
In the embodiment, by acquiring frequency spectrum information of a target audio, a first audio adjusting parameter of the target audio is set according to the frequency spectrum information; acquiring the number of audio playing devices, and acquiring a second audio adjusting parameter based on the number of the audio playing devices and the first audio adjusting parameter; and when the target audio is played, adjusting the target audio according to the second audio adjusting parameter. Through the mode, the first audio adjusting parameter is set according to the frequency spectrum information of the target audio before the target audio is played, so that the audio adjustment can be matched with the actual frequency spectrum condition of the target audio; further adjusting the first audio adjusting parameters according to the number of the audio playing devices to obtain second audio adjusting parameters, so that the audio adjustment is also adapted to the number of the current audio playing devices; finally, the target audio is adjusted according to the second audio adjusting parameter when the audio is played, dynamic adjustment of the audio parameter to be played in the audio switching process is achieved, negative effects brought to users and equipment due to sudden change of the related audio parameter when the audio is switched are avoided, automatic adjusting capacity of the intelligent large-screen equipment when the audio is switched is improved, and the technical problem that the adjusting capacity of the existing intelligent large-screen equipment is poor when the audio is switched is solved.
Further, a second embodiment of the audio adjusting method of the present invention is proposed based on the above-mentioned first embodiment shown in fig. 2, and in this embodiment, the step S10 includes:
starting switching event detection, and determining the switching type of the switching event when the switching event is detected;
acquiring a frequency spectrum file of a target audio pointed by the switching event, and identifying a high-frequency volume ratio from the frequency spectrum file as the frequency spectrum information;
and setting a first audio adjusting parameter of the target audio by combining the switching type and the high-frequency volume ratio.
In the present embodiment, for convenience of description, the smart phone is taken as an example below. And the intelligent television establishes a thread for detecting a switching event in a normal working state. Wherein the handover event comprises: switching from one program to another; switching from a program to an audio application or vice versa; switching from a program to a media video application or from a media video application to a program; switching from an audio application to a media video application or from a media video application to an audio application. Accordingly, the handover types include: a switch to a type of program, a switch to a type of audio application, and a switch to a type of media video application. The smart television acquires the name of the switched target audio according to the currently detected switching event, and acquires the corresponding frequency spectrum file according to the name. The intelligent television calculates the high-frequency volume ratio, such as 60%, in the spectrum file, and finally, the two factors of the switching type and the high-frequency volume ratio are comprehensively considered to set a first audio adjusting parameter.
Further, the first adjustment parameter includes a high frequency gain attenuation ratio,
setting a first audio adjusting parameter of the target audio in combination with the switching type and the high-frequency volume ratio, including:
searching a high-frequency proportion threshold corresponding to the switching type from a preset type threshold comparison rule;
and when the high-frequency volume ratio exceeds the high-frequency ratio threshold, setting the high-frequency gain attenuation ratio of the target audio frequency as a complementary value of the high-frequency ratio threshold.
In the present embodiment, the high-frequency gain attenuation ratio refers to an attenuation ratio value of the high-frequency volume gain. For example, if the original high-frequency gain is 60% and the attenuation ratio of the high-frequency gain is 50%, the attenuated high-frequency gain is 30%. The preset type threshold comparison rule is the preset corresponding relation between different switching types and high-frequency proportional thresholds. For example, the high frequency proportion threshold corresponding to the switching type of switching to the program is 60%; the high frequency proportion threshold value corresponding to the switching type for switching to the audio application is 50%; the high frequency proportion threshold value corresponding to the switching type for switching to the media video application is 30%. The complementary value of the high frequency scale threshold is a value added to the high frequency scale threshold to 1. For example, if the high frequency scale threshold value i 60%, its complementary value is 40%; if the high frequency ratio threshold is 30%, the complementary value is 70%.
Specifically, if the smart television detects that the current switching type is switching to a program, the high-frequency proportion threshold corresponding to the type is found to be 60% according to the preset type threshold comparison rule. The intelligent television judges whether the high-frequency volume ratio of the audio of the switched program is more than 60%, if so, the intelligent television calculates that the complementary value at the moment is 40%, which means that the high-frequency gain of the target audio is attenuated to the original 40%; if the target audio frequency is not larger than the preset target audio frequency, the intelligent television plays the target audio frequency as usual.
Further, step S20 includes:
detecting the actual operating power of externally connected audio playing devices, and acquiring the number of the externally connected audio playing devices of which the actual operating power is greater than a preset minimum power threshold value to serve as the number of the audio playing devices;
judging whether the number of the audio playing devices is more than 1;
and if so, acquiring an adjustment average value of the first audio adjustment parameter evenly distributed to each externally connected sound box, and taking the adjustment average value as the second audio adjustment parameter.
In this embodiment, the preset minimum power threshold is an operation power value of the audio playing device in a normal operating state. The intelligent television searches externally connected sound boxes and obtains the actual operating power of each sound box. Assuming that 3 external sound boxes exist, the lowest power threshold of the sound boxes is 15W, and the smart television compares the actual operating power of each sound box with 15W to obtain the number of the sound boxes with the actual power larger than 15W. The intelligent television judges whether the number of the sound boxes with the actual power larger than 15W is larger than 1. Assuming that the number of the sound boxes with the actual power larger than 15W is 2, it can be determined that the actual power is larger than 1, and the smart television can halve the high-frequency gain attenuation ratio, that is, the first audio adjustment parameter, for example, if the original high-frequency gain attenuation ratio is 40%, 20% is obtained after halving the high-frequency gain attenuation ratio, and 20% is the second audio adjustment parameter.
Further, after determining whether the number of the audio playing devices is greater than 1, the method further includes:
if not, taking the first audio adjusting parameter as the second audio adjusting parameter when the number of the audio playing devices is 1; or the like, or, alternatively,
and when the number of the audio playing devices is 0, generating and outputting abnormal prompt information.
In this embodiment, if the smart television detects that the number of the sound boxes with the actual power greater than 15W is 1, the first audio adjusting parameter does not need to be processed, and can be directly used as the second audio adjusting parameter; if the intelligent television detects that the number of the sound boxes with the actual power larger than 15W is 01, namely the sound boxes which can play the audio currently do not exist, the intelligent television generates and displays abnormal prompt information to prompt a user that the currently unavailable equipment can play the target audio normally.
In the embodiment, the first audio adjusting parameter is further set by combining the switching type and the high-frequency volume proportion type, so that the setting of the first audio adjusting parameter is more suitable for actual requirements, and the effectiveness of the first audio adjusting parameter is improved; the number of the audio playing devices is classified, and different second audio adjusting parameters are set according to different numbers, so that the difference of audio adjusting requirements under different number conditions is considered, the application range of the audio adjusting device is further expanded, and the effectiveness of the second audio adjusting parameters is improved.
Further, based on the first embodiment shown in fig. 2 described above, a third embodiment of the audio adjusting method of the present invention is proposed. In the present embodiment, step S30 includes:
and when the target audio is played, transmitting the second audio adjusting parameter to an audio power amplifier so as to perform smooth transition adjustment on the target audio based on the audio power amplifier.
In this embodiment, the audio power amplifier and the speaker are internal devices included in the audio equipment. When the intelligent television calculates the second audio adjusting parameter, the second audio adjusting parameter is transmitted to the audio power amplifier of the external sound equipment, so that the audio power method device can attenuate the high-frequency gain of the target audio according to the second audio adjusting parameter and then play the target audio through the sound box, and the switching mode adopted in the switching process is smooth switching so as to improve the user experience.
Further, after step S30, the method further includes:
and generating and displaying an adjusting control of the audio parameter index corresponding to the second audio adjusting parameter, so that a user can autonomously adjust the audio parameter index based on the adjusting control.
In this embodiment, in order to give the user a greater adjustment autonomy to the audio, after the smart television is switched to the next target audio, the audio parameter index corresponding to the second audio adjustment parameter, for example, the adjustment control of the high-frequency gain, the volume, and the like, may also be displayed on the screen, so that the user autonomously adjusts according to his/her own will on the basis of the automatic adjustment of the device. The adjusting control is generally set to be a percentage adjusting progress bar, an increase and decrease adjusting button and the like, and can be optionally set according to actual requirements, and the implementation is not particularly limited.
In this embodiment, smooth transition is further performed when the target audio is switched, so that the switching process is not excessively abrupt, and the audio and video viewing experience of a user is improved; through showing the regulation controlling part that corresponds, provide bigger autonomy for the user, the user can adjust once more on setting up the audio parameter after the automatically regulated according to actual demand or individual preference, has further promoted user experience, has also promoted the intelligence of this application to the audio regulation simultaneously.
