Background
The quality of the audio can be embodied by the code rate, the higher the code rate is, the higher the quality of the audio is, the higher the required network speed is, and the better the listening feeling is brought to the user. With the popularization of mobile traffic, a larger network speed can be guaranteed even under the condition of using the traffic. Therefore, the flow is no longer the main reference factor influencing the bitrate selection of the online audio by the user. However, in the prior art, the code rate switching manner for the online audio is still switched based on the used network, and generally, when the online audio is switched from the WIFI environment to the mobile network, the code rate of the online audio is switched to a relatively low code rate.

In a second aspect, a mobile terminal is provided, including: the first judgment module is used for judging whether the environmental volume exceeds a threshold volume or not according to the environmental volume acquired by the microphone; the acquisition module is used for acquiring the network speed of the mobile terminal if the environmental volume exceeds a threshold volume; and the switching module is used for switching the currently played online audio into the online audio with a first code rate if the network speed is less than a first threshold value, wherein the first code rate is less than the code rate of the currently played online audio.

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 some, not all, embodiments of the present invention. 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.
First embodiment
The first embodiment of the invention provides a method for switching the quality of online audio. The method is used for the mobile terminal. As shown in fig. 1, the method specifically includes the following steps:
step S101: and judging whether the ambient volume exceeds a threshold volume or not according to the ambient volume acquired by the microphone.
The quality of the online audio can be embodied by code rate, and the higher the code rate is, the higher the quality of the online audio is, and the better listening feeling can be brought to a mobile terminal user. However, in a noisy environment, even if the code rate of the online audio is high, the mobile terminal user cannot obtain a good listening feeling due to the interference of the environment. Generally, whether it is a noisy environment can be determined by the volume of the environment. Therefore, whether the environmental volume exceeds the threshold volume is judged through the step, so that corresponding processing can be carried out according to the judgment result.
If the ambient volume exceeds the threshold volume, the mobile terminal is in a quieter environment, for example, when the mobile terminal is in a quiet office or home, the code rate of the online audio does not need to be switched, and the online audio is continuously played at the current code rate.
Step S102: and if the environmental volume exceeds the threshold volume, acquiring the network speed of the mobile terminal.
The higher the code rate of the online audio, the larger the online audio file is, and the higher the requirement on the network speed is. Therefore, if the ambient volume exceeds the threshold volume, and the current environment of the mobile terminal is a noisy environment, the mobile terminal user is difficult to obtain a better listening feeling. Under the condition, if the network speed is lower, the online audio with lower code rate can be played, so that the network speed can be reasonably distributed, and if the flow networking is adopted, the flow can be saved, and the hearing of the mobile terminal user cannot be influenced. If the network speed is higher, the network speed can support the simultaneous operation of various tasks needing the network speed, and the code rate of the online audio can be kept to be played continuously.
Specifically, in the process of online audio playing, the network speed can be read at intervals by calling a judgment network speed interface class (for example, android traffic classes) of the mobile terminal, so as to determine the current network speed.
Step S103: and if the network speed is less than a first threshold value, switching the currently played online audio into the online audio with the first code rate.
And the first code rate is smaller than the code rate of the currently played online audio. The first threshold value can be set by a mobile terminal system or by a mobile terminal user according to the actual situation. If the network speed currently used by the mobile terminal is less than the first threshold, the network speed is low, so that the influence on other tasks due to the fact that the playing of the online audio occupies more network speed is avoided, or the waste of the traffic when the traffic networking is used is avoided, and the code rate of the online audio can be switched. The online audio may include online audio with multiple code rates, and the currently played online audio is switched to the online audio with the first code rate as long as the currently played online audio is not the online audio with the lowest code rate, so that the online speed occupied by the online audio is ensured to be the minimum, and the flow is saved. Specifically, the first code rate may be the lowest code rate, or may be a first code rate that is switched to a more appropriate code rate according to the network speed.
To sum up, the method for switching the quality of the online audio according to the first embodiment of the present invention switches the currently played online audio to the online audio with the smaller first code rate by comprehensively considering two factors, namely the environmental volume and the network speed, when the environmental volume exceeds the threshold volume and the network speed is smaller than the first threshold, so that the occupied network speed is the minimum without reducing the hearing of the mobile terminal user, and the traffic can be saved when the traffic networking is used.
Second embodiment
The second embodiment of the invention provides a quality switching method of online audio. The method is used for the mobile terminal. As shown in fig. 2, the method specifically includes the following steps:
step S201: and judging whether the currently played audio is online audio.
If the audio is not online, namely the audio stored locally in the mobile terminal, the occupation of network speed or the consumption of flow cannot be involved. Typically, locally stored audio also has no other bitrate audio available for switching. Therefore, if the currently played audio is not the online audio, the code rate cannot be switched, and the subsequent steps are not required.
Step S202: and if the currently played audio is the online audio, judging whether the currently played online audio comprises the online audio with different code rates.
In order to realize the switching of the online audio with different code rates of the embodiment, the online audio needs to include the online audio with different code rates. Therefore, whether the online audio provides the online audio with other switchable code rates can be judged through the step. The online audio may include online audio with multiple bitrate rates, such as a normal bitrate rate, an HQ bitrate rate, an SQ bitrate rate, and the like. If the online audio only has the online audio with one code rate, the online audio with different code rates can not be switched, and subsequent steps are not required.
Step S203: and if the currently played online audio comprises online audio with different code rates, judging whether the currently played online audio is the online audio with the lowest code rate.
The step can judge whether the online audio is the online audio with the lowest code rate. If the online audio is the lowest-bit-rate online audio, the switching is not needed.
Step S204: and if the currently played online audio is not the online audio with the lowest code rate, acquiring the environmental volume through a microphone.
If the online audio is not the online audio with the lowest code rate, the noisy degree of the environment needs to be considered to determine whether the online audio needs to be switched to the online audio with the smaller code rate. Therefore, whether the environment volume is enough to influence the hearing of the mobile terminal user can be judged by acquiring the environment volume of the environment where the mobile terminal is currently located.
Step S205: and judging whether the ambient volume continuously exceeds the threshold volume within a first preset time.
The ambient volume may be greater than the threshold volume at one moment and less than the threshold volume at other moments. In this case, the environment should not be considered a noisy environment, and the hearing of the user of the mobile terminal is not continuously affected. Therefore, the environment is regarded as a noisy environment only by collecting the volume of the environment higher than the threshold volume once, which affects the hearing of the mobile terminal user and is inaccurate. To avoid such a false determination, the volume of the environment is required to continuously exceed the threshold volume for a first predetermined time to indicate that the environment is a noisy environment. The threshold volume can be set by the mobile terminal system or by the mobile terminal user according to the actual situation.
Step S206: and if the environmental volume exceeds the threshold volume, acquiring the network speed of the mobile terminal.
The higher the code rate of the online audio, the larger the online audio file is, and the higher the requirement on the network speed is. Therefore, if the ambient volume exceeds the threshold volume, and the current environment of the mobile terminal is a noisy environment, the mobile terminal user is difficult to obtain a better listening feeling. Under the condition, if the network speed is lower, the online audio with lower code rate can be played, so that the network speed can be reasonably distributed, and if the flow is adopted for listening to songs, the flow can be saved, and the listening feeling of a mobile terminal user can not be influenced. If the network speed is higher, the network speed can support the simultaneous operation of various tasks needing the network speed, and the code rate of the online audio can be kept to be played continuously.
Specifically, in the process of online audio playing, the network speed can be read at intervals by calling a judgment network speed interface class (android traffic classes) of the mobile terminal, so that the current network speed is determined.
Step S207: and if the network speed is less than the first threshold value, prompting the mobile terminal user to switch the online audio into the online audio with the first code rate.
And the first code rate is smaller than the code rate of the currently played online audio. The first threshold value can be set by a mobile terminal system or by a mobile terminal user according to the actual situation. If the network speed currently used by the mobile terminal is less than the first threshold, the network speed is low, so that the situation that the playing of the online audio occupies more network speed and affects other tasks is avoided, or the situation that the traffic is wasted when the traffic networking is used is avoided, and a user of the mobile terminal can be prompted to switch the online audio into the online audio with the first code rate. The first code rate may be the lowest code rate, or may be the first code rate that is switched to be more appropriate according to the network speed.
Specifically, the mobile terminal user can be prompted to switch in a pop-up window mode.
And if the switching operation of the mobile terminal user is received within the second preset time after the prompt is sent, performing step S208. If the switching operation of the mobile terminal user is not received within the second preset time after the prompt is sent, step S209 is performed.
Step S208: and switching the online audio into the online audio with the first code rate based on the switching operation of the mobile terminal user.
After receiving the prompt, the mobile terminal user can perform an operation of confirming the switching by touching the switching graphic button or by pressing the mechanical button. After receiving the switching operation, the mobile terminal can switch the online audio into the online audio with the first code rate, so that the network speed occupied by the online audio is ensured to be minimum, and the flow is saved.
Step S209: and automatically switching the online audio into the online audio with the first code rate.
The prompt issued in step S207 may be a delay message. If the mobile terminal user does not actively respond within the second preset time, namely the mobile terminal does not receive the switching operation of the mobile terminal user, the mobile terminal responds to the delay message and automatically switches the online audio into the online audio with the first code rate, so that the network speed occupied by the online audio is minimum, and the flow is saved.
To sum up, the code rate switching method for the online audio according to the second embodiment of the present invention switches the online audio to the online audio with the smaller first code rate by comprehensively considering two factors, namely, the environmental volume and the network speed, under the condition that the environmental volume continuously exceeds the threshold volume within the first preset time and the network speed is less than the first threshold, so that the occupied network speed is the minimum under the condition that the hearing of the mobile terminal user is not reduced, and the traffic can be saved when the traffic networking is used.
Third embodiment
A third embodiment of the present invention provides a mobile terminal. Preferably, the mobile terminal of this embodiment may be, but is not limited to, a mobile phone, a tablet computer, MP3/MP4, a Personal Digital Assistant (PDA), a car computer, and the like. As shown in fig. 3, the mobile terminal 300 specifically includes the following modules:
the first determining module 301 is configured to determine whether the ambient volume exceeds a threshold volume according to the ambient volume acquired by the microphone.
The quality of the online audio can be represented by the code rate, and the higher the code rate is, the higher the quality of the online audio is, which can bring better hearing to the user of the mobile terminal 300. However, in the case of a noisy environment, even if the quality of the online audio is high, the user of the mobile terminal 300 cannot obtain a good listening feeling due to the interference of the environment. Generally, whether it is a noisy environment can be determined by the volume of the environment. Therefore, whether the environmental volume exceeds the threshold volume is judged through the module, and corresponding processing can be carried out according to the judgment result.
If the ambient volume exceeds the threshold volume, the mobile terminal 300 is in a quieter environment, for example, when the mobile terminal 300 is in a quiet office or home, the switching of the code rate of the online audio is not required, and the online audio is continuously played at the current code rate.
An obtaining module 302, configured to obtain a network speed of the mobile terminal 300 if the ambient volume exceeds a threshold volume.
The higher the code rate of the online audio, the larger the online audio file is, and the higher the requirement on the network speed is. Therefore, if the ambient volume exceeds the threshold volume, and the current environment of the mobile terminal 300 is a noisy environment, the user of the mobile terminal 300 is difficult to obtain a better listening feeling. In this case, if the network speed is low, the on-line audio with low code rate can be played, so that the network speed can be reasonably distributed, and if the traffic networking is adopted, the traffic can be saved, and the listening feeling of the user of the mobile terminal 300 cannot be influenced. If the network speed is higher, the network speed can support the simultaneous operation of various tasks needing the network speed, and the code rate of the online audio can be kept to be played continuously.
Specifically, in the process of playing the online audio, the network speed can be read at intervals by calling the network speed interface class (android traffic classes) of the mobile terminal 300, so as to determine the current network speed.
The switching module 303 is configured to switch the currently played online audio to an online audio with a first code rate if the network speed is less than a first threshold.
And the first code rate is smaller than the code rate of the currently played online audio. The first threshold may be set by the mobile terminal 300 system, or may be set by the user of the mobile terminal 300 according to actual conditions. If the network speed currently used by the mobile terminal 300 is less than the first threshold, it indicates that the network speed is slow, so as to avoid that playing the online audio occupies a large network speed and affects other tasks, or avoid wasting the traffic when using traffic networking, and this module can switch the code rate of the online audio. The online audio may include online audio with multiple code rates, and the module switches the currently played online audio to the online audio with the first code rate as long as the currently played online audio is not the online audio with the lowest code rate, so as to ensure that the online speed occupied by the online audio is the minimum and save the flow. Specifically, the first code rate may be the lowest code rate, or may be a first code rate that is switched to a more appropriate code rate according to the network speed.
To sum up, the mobile terminal 300 according to the third embodiment of the present invention comprehensively considers two factors, namely, the ambient volume and the network speed, so that when the ambient volume exceeds the threshold volume and the network speed is less than the first threshold, the currently played online audio is switched to the online audio with the smaller first bitrate, so that the occupied network speed is the minimum without reducing the hearing of the user of the mobile terminal 300, and the traffic can be saved when the traffic is used for networking.
Fourth embodiment
A fourth embodiment of the present invention provides a mobile terminal. Preferably, the mobile terminal of this embodiment may be, but is not limited to, a mobile phone, a tablet computer, MP3/MP4, a Personal Digital Assistant (PDA), a car computer, and the like. As shown in fig. 4, the mobile terminal 400 specifically includes the following modules: a first judging module 401, an obtaining module 402 and a switching module 403. The functions of the modules are the same as those of the third embodiment, and are not described again here.
Preferably, the mobile terminal 400 further includes:
the second determining module 404 is configured to determine whether the currently played audio is an online audio before the step of determining whether the ambient volume exceeds the threshold volume according to the ambient volume acquired by the microphone.
If the audio is not online, that is, the audio stored locally in the mobile terminal 400, the occupation of the network speed or the consumption of the traffic will not be involved. Typically, locally stored audio also has no other bitrate audio available for switching. Therefore, if the currently played audio is not the online audio, the code rate cannot be switched, and the subsequent process is not needed.
The third determining module 405 is configured to determine whether the currently played online audio includes online audio with different code rates if the currently played audio is online audio.
In order to realize the switching of the online audio with different code rates of the embodiment, the online audio needs to include the online audio with different code rates. Therefore, whether the online audio provides the online audio with other switchable code rates can be judged through the module. The online audio may include online audio with multiple bitrate rates, such as a normal bitrate rate, an HQ bitrate rate, an SQ bitrate rate, and the like. If the online audio only has the online audio with one code rate, the online audio with different code rates can not be switched, and the subsequent process is not needed.
Preferably, the mobile terminal 400 further includes:
a fourth determining module 406, configured to determine whether the currently played online audio includes online audio with different code rates, and if the currently played online audio includes online audio with different code rates, determine whether the currently played online audio is the online audio with the lowest code rate.
The module can judge whether the online audio is the online audio with the lowest code rate. If the online audio is the lowest-bit-rate online audio, the switching is not needed.
Preferably, the first determining module 401 includes:
the first obtaining sub-module 4011 is configured to obtain, through the microphone, the ambient volume if the currently played online audio is not the online audio with the lowest code rate.
If the online audio is not the online audio with the lowest code rate, the noisy degree of the environment needs to be considered to determine whether the online audio needs to be switched to the online audio with the smaller code rate. Accordingly, it may be determined whether the ambient volume is sufficient to affect the hearing of the user of the mobile terminal 400 by obtaining the ambient volume of the environment in which the mobile terminal 400 is currently located.
The determining sub-module 4012 is configured to determine whether the ambient volume continuously exceeds the threshold volume within a first preset time.
The ambient volume may be greater than the threshold volume at one moment and less than the threshold volume at other moments. In this case, the environment should not be considered a noisy environment and will not continuously affect the hearing of the user of the mobile terminal 400. Therefore, the environment is considered to be a noisy environment only by collecting the ambient volume once above the threshold volume, which may affect the hearing of the user of the mobile terminal 400 and is inaccurate. To avoid such a false determination, the volume of the environment is required to be continuously greater than the threshold volume for a first preset time period to indicate that the environment is a noisy environment. The threshold volume may be set by the mobile terminal 400 system or may be set by the user of the mobile terminal 400 based on the actual situation.
Whether the environment in which the mobile terminal 400 is located affects the hearing of the user of the mobile terminal 400 may be determined by the sub-modules described above.
If the ambient volume exceeds the threshold volume, the obtaining module 402 performs the step of obtaining the network speed of the mobile terminal 400.
If the volume of the environment exceeds the threshold volume, and the current environment of the mobile terminal 400 is a noisy environment, the user of the mobile terminal 400 is difficult to obtain a better listening feeling. In this case, if the network speed is low, the online audio with a low code rate can be played, so that the network speed can be reasonably distributed, and if the flow is adopted for listening to songs, the flow can be saved, and the listening feeling of the user of the mobile terminal 400 cannot be influenced. If the network speed is higher, the network speed can support the simultaneous operation of various tasks needing the network speed, and the code rate of the online audio can be kept to be continuously played
Preferably, the switching module 403 includes:
the prompting submodule 4031 is configured to prompt the user of the mobile terminal 400 to switch the online audio to the online audio with the first code rate if the network speed is smaller than the first threshold.
And the first code rate is smaller than the code rate of the currently played online audio. The first threshold may be set by the mobile terminal 400 system, or may be set by the user of the mobile terminal 400 according to actual conditions. If the network speed currently used by the mobile terminal 400 is less than the first threshold, it indicates that the network speed is slow, so as to avoid that playing the online audio occupies a large network speed and affects other tasks, or avoid wasting the traffic when using traffic networking, and prompt the user of the mobile terminal 400 to switch the online audio into the online audio with the first code rate. The first code rate may be the lowest code rate, or may be the first code rate that is switched to be more appropriate according to the network speed.
Specifically, the prompt sub-module 4031 may prompt the user of the mobile terminal 400 to perform handover in a pop-up window manner.
The first switching sub-module 4032 is configured to, if the switching operation of the user of the mobile terminal 400 is received within the second preset time after the prompt is sent, switch the online audio to the online audio with the first code rate based on the switching operation of the user of the mobile terminal 400.
The user of the mobile terminal 400 may perform an operation of confirming the switching by touching the switching graphic button or by pressing the mechanical button after receiving the prompt. After the mobile terminal 400 receives the switching operation, the first switching sub-module 4032 may switch the online audio to the online audio with the first code rate, so as to ensure that the online audio occupies the minimum network speed and save the traffic.
And the second switching sub-module 4033 is configured to automatically switch the online audio to the online audio with the first code rate if the switching operation of the user of the mobile terminal 400 is not received within a second preset time after the prompt is sent.
The prompt issued by the prompt sub-module 4031 may be a delayed message. If the user of the mobile terminal 400 does not actively respond within the second preset time, that is, the mobile terminal 400 does not receive the switching operation of the user of the mobile terminal 400, the second switching sub-module 4033 will respond to the delay message and automatically switch the online audio to the online audio with the first code rate, so as to ensure that the online speed occupied by the online audio is minimum and save the flow.
To sum up, the mobile terminal 400 according to the fourth embodiment of the present invention, by comprehensively considering two factors, namely, the ambient volume and the network speed, switches the online audio to the online audio with the smaller first code rate when the ambient volume continuously exceeds the threshold volume within the first preset time and the network speed is less than the first threshold, so that the occupied network speed is the minimum without reducing the hearing of the user of the mobile terminal 400, and the traffic can be saved when the traffic networking is used.
