Detailed Description
The embodiment of the application provides a processing method and device for an ear return function and a mobile terminal.
in order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, 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 application.
Example one
as shown in fig. 1, an execution main body of the method may be a terminal device, where the terminal device may be a device such as a personal computer, or may also be a mobile terminal device such as a mobile phone and a tablet computer, and the terminal device may be a terminal device used by a user. The terminal equipment is connected with external equipment, and the terminal equipment and the external equipment both have ear return functions. The method can be used for judging whether the ear return function of the terminal equipment conflicts with the ear return function of the terminal equipment peripheral equipment, determining whether the ear return function of the terminal equipment is started, closing the ear return function of the terminal equipment when the ear return function is determined to be started, and the like. The method may specifically comprise the steps of:
In step S102, a first amplitude of audio data of a predetermined frequency band among currently output audio data is acquired.
The output audio Data (i.e., RX Data) may be audio Data output by the audio output port of the terminal device, and the output audio Data may be transmitted to the terminal device through a wireless network, or may be transmitted to the terminal device through a short-range wireless communication function (e.g., an NFC function or a bluetooth function). The predetermined frequency band may be set according to actual conditions, and the predetermined frequency band may be one frequency band or may include a plurality of different frequency bands. The first amplitude may be a maximum amplitude in the audio data of the predetermined frequency band, or may be an average amplitude of the audio data of the predetermined frequency band, and the energy of the sound corresponding to the audio data may be further determined by the first amplitude.
in practice, the earreturn function is a reminding or prompting means provided for the user to prevent the sound delay in a large space, for example, for the singer, the singer often cannot hear the sound produced by himself at the singing site, so the singer needs to monitor whether the sound produced by himself is off-tune or out-of-tune through earreturn. In addition, when the singer cannot hear the accompaniment or the accompaniment is delayed, the accompaniment is transmitted to the ear of the singer while the ear returns. Since the performance site is not a small room, there is a delay in sound (i.e. the time when the singer hears the accompaniment is often delayed compared with the actual time when the accompaniment is actually performed) or deterioration, so that the accompaniment is sent to the ears of the singer through the return ears to ensure that the singer does not sing wrong beats or getting out of tune. As another example, for the host, the director may direct the host to schedule the associated program via an ear return, such as inserting a commercial, guest entry, or correcting a miscounting. With the continuous development of terminal technology, terminal equipment becomes an essential tool in life and work of people, and the ear return function has the advantages or benefits, so that the function is also arranged in many terminal equipment.
As shown in fig. 2, specifically, for the terminal device, the audio playing and the recording are two different functions, and when the two functions are actually executed, the audio playing and the recording are also respectively executed by two different threads, but there is a corresponding interrupt program between the two threads, so as to facilitate data transmission. When the interrupt program needs to be executed, in the process of processing the digital signal, the audio Data of TX (Transmit) Data can be extracted, and RX (receive) audio Data (audio Data to be played) can be extracted, corresponding addition operation is performed, and then the operation result (i.e. the audio Data of RX Data) is transmitted to the earphone, so that the sound emitted by the earphone can be heard in the earphone.
in practical application, not only the terminal device is provided with the ear return function, but also a plurality of external devices of the terminal device are provided with the ear return function, if the ear return function of the terminal device and the ear return function of the external device of the terminal device are simultaneously started, the sound effect finally heard by the user can be influenced, specifically, as shown in fig. 3, the external device superposes the audio data output by the playback channel and the audio data after the audio data enters the microphone for effect processing, the audio data are superpositioned on the external device again according to a corresponding algorithm, and then the superpositioned audio data are conveyed to the earphone, so that the user can hear the own sound in the earphone. However, as can be seen from fig. 2 and 3, if the ear return function of the terminal device is turned on and the external device also turns on the mixing switch, a loop will appear on the path of the audio data, which results in that the sound is circularly amplified, and the sound generates noise. Therefore, an embodiment of the present application provides a method for processing an ear return function, which may specifically include the following steps:
Based on the above fig. 2, an audio playing application may be installed in the terminal device, wherein the audio playing application provides a karaoke function, and in addition, the terminal device may be provided with an ear return function. When a user needs to use the terminal device to perform karaoke, the audio playing application installed in the terminal device can be started, the starting key with the karaoke function is found in the audio playing application, then the starting key can be clicked, the terminal device can start the karaoke function and send a notification message to a corresponding server, after the server receives the notification message, the server can acquire relevant information (such as room names or room numbers) of currently established or started karaoke rooms and send the information to the terminal device, and the terminal device can display the information. The user can browse the above information, can find a specified room or a room desired to enter from it, and can click to enter the room thereafter. The terminal equipment can obtain the name or number and other identifiers of the room clicked by the user, a karaoke request can be generated according to the identifiers and sent to the corresponding server, and after the server receives the karaoke request, the server can send the related data of the room corresponding to the room identifier contained in the karaoke request to the terminal equipment. The terminal device receives and displays relevant data of the room, such as relevant information, a microphone-up key, song selection items and the like of a K song user in the room, at the moment, the user can select songs, the microphone-up key can be clicked after the selection is completed, and the terminal device can start a microphone or connect a microphone. Meanwhile, the user can connect the earphone with the terminal equipment, the terminal equipment can output the audio Data of the accompaniment of the song selected by the user through the earphone, meanwhile, the microphone of the terminal equipment or the microphone of the external equipment can receive the voice Data of the user, the terminal equipment can superpose or add the received voice Data and the audio Data of the outputted accompaniment, finally, the audio Data to be outputted (namely, RX Data in fig. 2) is obtained, the audio Data to be outputted can be inputted into the earphone through the earphone jack, and therefore the currently outputted audio Data is obtained. Then, spectral analysis may be performed on the currently output audio data, the currently output audio data may be divided into one or more different frequency bins according to a spectral structure of the currently output audio data, and an amplitude of each frequency bin may be calculated as the first amplitude.
In step S104, it is determined whether there is a conflict between the earreturn function of the terminal device and the earreturn function of the external device based on the first amplitude.
In implementation, an amplitude threshold may be set and stored in the terminal device, where, for a case that the first amplitude includes amplitudes of audio data of a plurality of different frequency bands, a corresponding amplitude threshold may be set for each amplitude, or only one amplitude threshold may be set, and the like, which is not limited in this embodiment of the application. After the terminal device obtains the first amplitude of the audio data of the predetermined frequency band in the currently output audio data through the processing of the step S102, the first amplitude may be compared with a preset amplitude threshold, and if the first amplitude is higher than the preset amplitude threshold, it is determined that there is noise in the output audio data, and it may be determined that the external device of the terminal device has started the ear return function. And if the first amplitude is compared with a preset amplitude threshold value, and the first amplitude is determined not to exceed the preset amplitude threshold value, determining that the ear return function of the terminal equipment and the ear return function of the external equipment are not in conflict.
It should be noted that, in the above, whether the ear-return function of the terminal device and the ear-return function of the external device conflict with each other is determined in an amplitude manner, in practical application, whether the ear-return function of the terminal device and the ear-return function of the external device conflict with each other may also be determined in a manner of sound energy corresponding to audio data, specifically, the first amplitude may be squared, the obtained value is multiplied by an energy parameter to finally obtain sound energy corresponding to the audio data, and then, whether the ear-return function of the terminal device and the ear-return function of the external device conflict with each other may be further determined according to a set energy threshold, which may specifically refer to the above related contents, and will not be described herein again.
In addition, for the case that the first amplitude includes the amplitudes of the audio data of a plurality of different frequency bands, a corresponding amplitude threshold may be set for the amplitude of the audio data of each frequency band, when it is determined whether the ear return function of the terminal device and the ear return function of the external device are in conflict, each amplitude in the first amplitude may be compared with its corresponding amplitude threshold, if each amplitude is greater than its corresponding amplitude threshold, it is determined that the ear return function of the terminal device and the ear return function of the external device are in conflict, otherwise, the ear return function of the terminal device and the ear return function of the external device are not in conflict.
in step S106, if there is a conflict between the ear return function of the terminal device and the ear return function of the external device, the ear return function of the terminal device is turned off.
The embodiment of the application provides a processing method of an ear return function, which is applied to a terminal device, the terminal device is connected with an external device, the terminal device and the external device have the ear return function, whether the ear return function of the terminal device conflicts with the ear return function of the external device is judged through a first amplitude of audio data of a preset frequency band in the current output audio data, if the ear return function of the terminal device conflicts with the ear return function of the external device, the ear return function of the terminal device is closed, thus, whether the ear return function of the terminal device and the ear return function of the external device are in an open state simultaneously can be determined only through the first amplitude of the audio data of the preset frequency band in the output audio data, whether the ear return function of the terminal device conflicts with the ear return function of the external device is judged, and when the ear return function of the terminal device conflicts with the ear return function of the external device, and the ear return function of the terminal equipment is closed, so that only the ear return function of the external equipment is used, the generation of noise possibly caused is eliminated, and the output audio data is prevented from being influenced.
example two
As shown in fig. 4, an execution main body of the method may be a terminal device, where the terminal device may be a device such as a personal computer, or may also be a mobile terminal device such as a mobile phone and a tablet computer, and the terminal device may be a terminal device used by a user. The terminal equipment is connected with external equipment, and the terminal equipment and the external equipment both have ear return functions. The method can be used for judging whether the ear return function of the terminal equipment conflicts with the ear return function of the terminal equipment peripheral equipment, determining whether the ear return function of the terminal equipment is started, closing the ear return function of the terminal equipment when the ear return function is determined to be started, and the like. The method may specifically comprise the steps of:
in step S402, a first amplitude of audio data of a predetermined frequency band among currently output audio data is acquired.
The content of the step S402 is the same as the content of the step S102 in the first embodiment, and the specific processing procedure of the step S402 may refer to the related content of the step S102 in the first embodiment, which is not described herein again.
In S404, if the first amplitude is greater than the second amplitude of the reference audio data of the predetermined frequency band in the reference audio data and the first amplitude exceeds a predetermined amplitude threshold, it is determined that the ear-return function of the terminal device and the ear-return function of the external device are in conflict.
The reference audio data may be audio data that does not contain any noise, and the reference audio data may be set or obtained in various ways, for example, initial data of currently output audio data may be used as the reference audio data, or previous frame audio data of currently output audio data may also be used as the reference audio data, and the like. The second amplitude may be a reference amplitude, the second amplitude may be the maximum amplitude in the reference audio data, or may be an average value of the amplitudes of the reference audio data, and the energy of the sound corresponding to the reference audio data may be further determined from the second amplitude.
In an implementation, the terminal device stores therein the reference audio data, and the second amplitude of the reference audio data of a predetermined frequency band in the reference audio data. In addition, an amplitude threshold may be set and stored in the terminal device, where, for a case that the first amplitude includes amplitudes of audio data of a plurality of different frequency bands, a corresponding amplitude threshold may be set for each amplitude, or only one amplitude threshold may be set, and the like, which is not limited in this embodiment of the application. After the terminal device obtains the first amplitude of the audio data of the predetermined frequency band in the currently output audio data through the processing of step S102, the first amplitude may be compared with the second amplitude, and if the first amplitude is smaller than the second amplitude, it may be determined that there is no conflict between the ear return function of the terminal device and the ear return function of the external device, and the detection process may be continuously performed. If the first amplitude is greater than the second amplitude, the first amplitude may be compared with a preset amplitude threshold, and if the first amplitude is lower than the preset amplitude threshold, it may be determined that there is no conflict between the ear return function of the terminal device and the ear return function of the external device, and the above-described detection process may be continuously performed. If the first amplitude is higher than the preset amplitude threshold value, it can be determined that the ear return function of the external device of the terminal device is started, and at the moment, the ear return function of the terminal device is also in a starting state, so that the collision between the ear return function of the terminal device and the ear return function of the external device is caused.
In addition, for the case that the first amplitude includes the amplitudes of the audio data of a plurality of different frequency bands, a corresponding amplitude threshold may be set for the amplitude of the audio data of each frequency band, and when it is determined whether the ear return function of the terminal device and the ear return function of the external device are in conflict, each of the first amplitudes may be compared with its corresponding second amplitude, and for the first amplitude larger than the corresponding second amplitude, the first amplitude is compared with the amplitude threshold, so as to determine whether the ear return function of the terminal device and the ear return function of the external device are in conflict.
it should be noted that, in order to simplify the processing procedure of the ear return function, the reference audio data may be implemented in a variety of ways besides the above-mentioned way, and an optional processing way is provided below, which may specifically include the following: if the reference audio data is the audio data of the previous frame of the currently output audio data, the processing of step S404 may be: and if the first amplitude is larger than the fourth amplitude of the reference audio data of the preset frequency band in the previous frame of audio data, and the first amplitude exceeds a preset amplitude threshold value, determining that the ear-return function of the terminal equipment and the ear-return function of the external equipment conflict.
In addition, the processing for determining that the ear return function of the terminal device and the ear return function of the external device conflict with each other may be implemented in the foregoing manner, and may also include a plurality of different implementation manners, where the following provides another optional implementation manner, and specifically may include the following: and if the difference value between the first amplitude of the audio data of the preset frequency section in the currently output audio data and the second amplitude of the reference audio data of the preset frequency section in the reference audio data exceeds a preset threshold value, determining that the ear return function of the terminal equipment and the ear return function of the external equipment conflict.
In an implementation, a threshold value of the difference between the amplitudes may be set, and the difference between the first amplitude and the second amplitude may be calculated based on the set threshold value. The difference between the first amplitude and the second amplitude may be an average value of a plurality of amplitude differences, or the difference between the first amplitude and the second amplitude may be a minimum value or a maximum value of the plurality of amplitude differences, or the like. After the corresponding difference value is obtained through the calculation, whether the difference value between the first amplitude and the second amplitude is larger than a corresponding preset threshold value or not can be calculated, if the two difference values are larger than the corresponding preset threshold values, it is determined that the ear return function of the terminal device and the ear return function of the external device are in conflict, and otherwise, the ear return function of the terminal device is in a closed state or the terminal device does not have the ear return function and the like.
in S406, the earreturn function of the terminal device is turned off.
after the terminal device turns off the ear return function of itself, it may continue to detect whether the output audio data is recovered to a normal state (i.e., whether the output audio is cyclically amplified), and the corresponding processing manner may be various, and an optional processing manner is provided below, which may be specifically referred to in step S408 and step S410 below.
In S408, next frame audio data of the currently output audio data is acquired, and a third amplitude of audio data of a predetermined frequency band in the next frame audio data is acquired.
in implementation, after the terminal device closes its ear return function, the terminal device may continue to output audio data of the accompaniment of the song selected by the user through the earphone, and at the same time, the microphone or the microphone of the terminal device may continue to receive voice data of the user, and at this time, the terminal device acquires audio data to be input to the earphone jack (i.e., next frame of audio data of currently output audio data). Then, spectral analysis may be performed on next frame audio data of the currently output audio data, the currently output audio data may be divided into one or more frequency bins according to a spectral structure of the next frame audio data, and an amplitude of each frequency bin may be calculated.
In S410, if the third amplitude is greater than the first amplitude and the third amplitude exceeds a predetermined threshold, it is determined that noise data exists in the input data corresponding to the currently output audio data.
In implementation, for the processing procedure of determining that the third amplitude is greater than the first amplitude and the third amplitude exceeds the predetermined threshold, reference may be made to the related content of step S404, which is not described herein again. Since the terminal device has turned off its ear-return function, even if the external device turns on the ear-return function (turns on the mixing switch), the audio data output from the headphone jack should not have audio data that is circularly amplified, and if the third amplitude is greater than the first amplitude and exceeds a predetermined threshold, it may be said that the audio data input into or played by the terminal device has noise or noise, for example, the terminal device receives noise generated by electromagnetic interference of other electronic devices, that is, it may be determined that there is noise data in the input data corresponding to the currently output audio data.
The embodiment of the application provides a processing method of an ear return function, which is applied to a terminal device, the terminal device is connected with an external device, the terminal device and the external device have the ear return function, whether the ear return function of the terminal device conflicts with the ear return function of the external device is judged through a first amplitude of audio data of a preset frequency band in the current output audio data, if the ear return function of the terminal device conflicts with the ear return function of the external device, the ear return function of the terminal device is closed, thus, whether the ear return function of the terminal device and the ear return function of the external device are in an open state simultaneously can be determined only through the first amplitude of the audio data of the preset frequency band in the output audio data, whether the ear return function of the terminal device conflicts with the ear return function of the external device is judged, and when the ear return function of the terminal device conflicts with the ear return function of the external device, and the ear return function of the terminal equipment is closed, so that only the ear return function of the external equipment is used, the generation of noise possibly caused is eliminated, and the output audio data is prevented from being influenced.
