In the existing technology for playing audio streams, uniform sound effect parameters are adopted for all audio streams. The method of adopting the uniform sound effect parameters cannot simultaneously meet the optimization of the playing effect of different audio streams, for example, in a vehicle-mounted terminal, an antenna of a radio is easily interfered by the vehicle speed or the work of other electronic elements in the vehicle, so that the effect of the radio for playing the broadcast audio signals is poor. At this time, audio algorithm suppression needs to be performed for frequency points that are easily interfered to optimize the playing effect of the broadcast audio signal, and if these frequency points are also suppressed for the multimedia audio signal, the effect of playing the multimedia audio signal is deteriorated. Therefore, in the prior art, a set of sound effect parameters for balancing the playing effects of the broadcast audio signal and the multimedia audio signal are often adjusted in a compromise way, and the respective playing effects are not optimal for the broadcast audio signal and the multimedia audio signal.

Detailed Description
The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.
Example 1
The audio playing control method provided by the embodiment is applied to electronic equipment, and in an audio playing scene, different sound effect parameters are adopted for playing different types of audio data, so that the playing effect of the different types of audio data can be optimal. The electronic device in this embodiment may be a mobile phone, a tablet computer, a PDA (personal digital assistant), a notebook computer, a vehicle-mounted terminal, or the like.
As shown in fig. 1, the audio playing control method provided in this embodiment includes the following steps:
step S101, determining the type of the audio data to be played.
In an alternative embodiment, the types of the audio data to be played include a broadcast audio signal and a multimedia audio signal. The broadcast audio signal refers to an audio signal transmitted by a broadcast station through radio waves, and can be played through a radio application program in the electronic device. The multimedia audio signal is an audio signal stored locally in the electronic device, an audio signal acquired through a network, or an external audio signal acquired through a transmission interface. In the example of the electronic device being a mobile phone, the transmission interface may be a Type-C interface. In the case of the electronic device being a computer, the transmission interface may be a USB interface. In the example of the electronic device being the in-vehicle terminal, the transmission interface may be an AUX interface (audio input interface) or a USB interface. In specific implementation, the multimedia audio signal may be music, voice, sound effect, or the like.
In an optional implementation manner of step S101, if it is detected that a radio application in the electronic device is triggered, it is determined that the type of the audio data to be played is a broadcast audio signal, otherwise, it is determined that the type of the audio data to be played is a multimedia audio signal. In this embodiment, a radio application is installed in the electronic device, and a user can open the radio application by clicking an icon of the radio application. In an alternative embodiment, the radio application is triggered to indicate that the radio application is in a foreground running state.
In another optional implementation manner of step S101, the type of the audio data to be played is determined according to the attribute of the audio data to be played. In this embodiment, the attribute of the audio data to be played includes parameters for characterizing the type of the audio data, and it can be determined whether the type of the audio data to be played is a broadcast audio signal or a multimedia audio signal through the parameters.
And S102, selecting corresponding sound effect parameters according to the type of the audio data to be played.
It should be noted that, in order to improve the effect of the electronic device for playing the audio data, the audio data to be played needs to be processed by using the audio algorithm, and the audio parameter in step S102 is a parameter involved in the audio algorithm.
In an optional embodiment, the sound effect parameter includes at least one of the following: EQ parameters, ALC parameters, AGC parameters. In the present embodiment, the sound effect algorithm is used to implement EQ, ALC and/or AGC functions. The EQ is configured to filter and amplify the audio signal, so as to adjust the gain of the audio signal in each frequency band, where the EQ parameter may be a filtering parameter and/or an amplifying parameter. The ALC is adapted to adjust the gain of the audio signal when the level of the audio signal exceeds a threshold value, and the ALC parameter may be a level threshold parameter. The AGC is used to automatically adjust the gain of the audio signal, and the AGC parameter may be a gain adjustment parameter.
In the present embodiment, for the same electronic device, different types of audio data correspond to different sound effect parameters. In a specific example, the sound effect parameters corresponding to the broadcast audio signal are Para1= { EQ1_ F, EQ1_ P, ALC1_ V, AGC1_ G }, and the sound effect parameters corresponding to the multimedia audio signal are Para2= { EQ2_ F, EQ2_ P, ALC2_ V, AGC2_ G }. Wherein EQ1_ F and EQ2_ F are filtering parameters, EQ1_ P and EQ2_ P are amplifying parameters, ALC1_ V and ALC2_ V are threshold parameters, and AGC1_ G and AGC2_ G are gain adjusting parameters.
It should be noted that, even if the types of audio data are the same for different electronic devices, the corresponding sound effect parameters are usually different due to the difference in the sizes of the electronic devices, the positions of the speakers in the electronic devices, the design of the sound cavities in the electronic devices, and the like.
And S103, playing the audio data to be played according to the sound effect parameters.
In the specific implementation of step S103, the sound effect parameters selected in step S102 are input into the audio hardware of the electronic device, so as to implement playing of the audio data. If the type of the audio data to be played is a broadcast audio signal, the audio effect parameters corresponding to the broadcast audio signal are input into audio hardware of the electronic equipment, and the broadcast audio signal is played after being processed by an audio effect algorithm, so that the playing effect of the broadcast audio signal is optimal. If the type of the audio data to be played is a multimedia audio signal, the audio effect parameters corresponding to the multimedia audio signal are input into audio hardware of the electronic equipment, and the multimedia audio signal is played after being processed by a sound effect algorithm, so that the playing effect of the multimedia audio signal is optimal.
Fig. 2 is a flowchart for illustrating an audio playback control method. As shown in fig. 2, it is detected whether a radio application program in the electronic device is triggered, and if it is detected that the radio application program is triggered, it is determined that the type of the audio data to be played is a broadcast audio signal, and a first sound effect parameter corresponding to the broadcast audio signal is selected, and the broadcast audio signal is played according to the first sound effect parameter. If the radio application program is not detected to be triggered, determining that the type of the audio data to be played is a multimedia audio signal, selecting a second sound effect parameter corresponding to the multimedia audio signal, and playing the multimedia audio signal according to the second sound effect parameter.
Compared with the prior art in which the unified sound effect parameters cannot meet the optimization of the playing effect of different audio data, the present embodiment in which different sound effect parameters are adopted for different types of audio data can optimize the playing effect of each type of audio data, thereby improving the experience of the user in using the electronic device.

In this embodiment, a radio application is installed in the electronic device, and a user can open the radio application by clicking an icon of the radio application. In an alternative embodiment, the radio application is triggered to indicate that the radio application is in a foreground running state.
In another optional embodiment, the determining module 31 is specifically configured to determine the type of the audio data to be played according to an attribute of the audio data to be played. In this embodiment, the attribute of the audio data to be played includes parameters for characterizing the type of the audio data, and it can be determined whether the type of the audio data to be played is a broadcast audio signal or a multimedia audio signal through the parameters.
The selecting module 32 is configured to select a corresponding sound effect parameter according to the type of the audio data to be played.
It should be noted that, in order to improve the effect of the electronic device for playing the audio data, the audio data to be played needs to be processed by using a sound effect algorithm, and the sound effect parameter in the step S102 is a parameter involved in the sound effect algorithm.
In an optional embodiment, the sound effect parameter includes at least one of the following: EQ parameters, ALC parameters, AGC parameters.
In the present embodiment, for the same electronic device, different types of audio data correspond to different sound effect parameters. It should be noted that, even if the types of audio data are the same for different electronic devices, the corresponding sound effect parameters are usually different due to the difference in the sizes of the electronic devices, the positions of the speakers in the electronic devices, the design of the sound cavities in the electronic devices, and the like.
