Detailed Description
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. It is to be understood that the embodiments described are only a few embodiments of the present application and not all 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.
Referring to fig. 1, fig. 1 is a first flowchart illustrating an audio playing method according to an embodiment of the present disclosure.
The audio playing method comprises the following steps:
Specifically, when the mobile terminal receives an incoming call or a message from another person, the prompt message is played according to a preset volume value set by a user on a setting interface of the mobile terminal. The mobile terminal may be a mobile phone, a tablet computer, a notebook computer, a personal digital assistant, and the like, and various application programs, such as applications having an entertainment function (e.g., a video application, an audio playing application, a game application, and reading software), and applications having a service function (e.g., a map navigation application, a dining application, and the like), are stored in the mobile terminal.
The prompt may be an audible prompt or a vibratory prompt, such as: a voice prompt message generated through a speaker of the mobile terminal, or a vibration prompt message generated by a vibration motor of the mobile terminal through vibration. It should be noted that if the prompt message is a vibration prompt message, since the volume values of the vibration prompt messages generated by different vibration frequencies are different, playing the vibration prompt message according to the preset volume value is to play the vibration prompt message according to the preset vibration frequency.
And 102, recording the prompt information in the playing process to obtain the current scene audio file.
When the prompt information is played according to the preset volume value, the mobile terminal records the prompt information played in the current scene, and certainly, if the user is in the operation scene, the user can also record external sounds except the mobile terminal.
Specifically, taking an operating system of the mobile terminal as an Android system (Android) as an example, the prompt information during recording and playing can be recorded through an interface of an Android development kit (Android SDK). And calling or triggering the interface of the Android SDK to record the prompt message played in the current scene every time the mobile terminal receives an incoming call or a message.
And 103, extracting the frequency spectrum characteristic of the current scene audio file, and judging whether the extracted target frequency spectrum characteristic value is within a preset frequency spectrum characteristic value range.
Specifically, the preset spectral feature value range is a spectral feature value range obtained by extracting spectral features of a preset audio file. In order to determine whether the current scene of the user is a noisy environment, it is necessary to ensure that the preset audio file is recorded by the mobile terminal in a quiet environment, and the mobile terminal must play the same prompt information as in step 101 in the quiet environment, otherwise, different prompt information cannot be compared according to the extracted spectral feature value.
The spectral feature extraction may adopt a fourier transform (FFT) algorithm to convert the acquired audio file into a frequency domain, thereby obtaining a frequency distribution characteristic. Referring to fig. 2, fig. 2 is a frequency distribution characteristic diagram obtained by recording vibration prompt information played by a mobile terminal in a quiet environment and extracting spectral features. As shown in fig. 2, in a quiet environment, the feature values of the sound generated when the mobile phone starts playing the vibration prompt message are 260Hz, 518Hz, and 775Hz, and since the frequency spectrum fluctuation of the mobile phone on different material surfaces (such as wood, plastic, glass, etc.) is ± 10Hz, taking the prompt message as the vibration prompt message as an example, if the frequency spectrum feature values of the current scene audio file are within 250Hz to 270Hz, 508Hz to 528Hz, and 765Hz to 785Hz, it is indicated that the current environment where the mobile terminal is located is the quiet environment; if the frequency spectrum characteristic value of the current scene audio file is not within 250 Hz-270 Hz, 508 Hz-528 Hz and 765 Hz-785 Hz, the current environment where the mobile terminal is located is a noisy environment.
In order to improve the accuracy of the mobile terminal in determining the current scene, the preset audio time of the preset audio file may be determined first, and when the prompt information in the playing process is recorded in step 102, the recording is also performed according to the preset audio time. Therefore, recording the prompt information in the playing process to obtain the current scene audio file includes:
and recording the prompt information in the playing process according to the preset duration to obtain the current scene audio file.
And step 104, if the target frequency spectrum characteristic value is not within the range of the preset frequency spectrum characteristic value, adjusting the preset volume value based on the preset audio file, and playing the preset audio file according to the adjusted volume value.
Specifically, if the target spectrum characteristic value is not within the preset spectrum characteristic value range, it indicates that the mobile terminal is currently in the noisy environment, and the preset volume value needs to be adjusted, so that the user can hear the sound emitted by the terminal in the noisy environment. The adjustment mode can be that the maximum amplitude value of a preset audio file recorded by the mobile terminal in a quiet environment is searched, and the maximum decibel value of the audio file coding mode is determined. For example: if the maximum amplitude of the audio file is preset to be A and the encoding mode of the audio file is PCM-8 BIT, it can be determined that the maximum decibel value allowed by the encoding mode is 27128, the ratio of the maximum decibel value to the maximum amplitude value is determined to be
It is determined to amplify the preset volume value
And (4) doubling. Therefore, adjusting the preset volume value based on the preset audio file includes:
acquiring the maximum amplitude of the preset audio file, acquiring a target amplitude, and acquiring a target coding mode of the audio file;
determining the maximum decibel value of the target coding mode to obtain a target decibel value;
determining an adjustment multiple according to the target decibel value and the target amplitude;
and adjusting the preset volume value according to the adjusting multiple.
The maximum amplitude is used for amplification, and distortion can be avoided after sound amplification.
In addition, if the target spectrum characteristic value is within the preset spectrum characteristic value range, which indicates that the mobile terminal is currently in a quiet environment, the prompt information may be played in a normal manner, for example, a speaker is used for playing a song, or a vibration motor is used for vibrating to prompt the user through vibration and sound. Thus, the method further comprises:
and if the target frequency spectrum characteristic value is within the preset frequency spectrum characteristic value range, playing prompt information according to a preset volume value.

And calling or triggering the interface of the Android SDK to record the prompt message played in the current scene every time the mobile terminal receives an incoming call or a message.
Specifically, in order to improve the accuracy of the mobile terminal in judging the current scene, the preset audio time of the preset audio file may be determined first, and the prompt information in the playing process is recorded according to the preset audio time.
The spectral feature extraction may adopt a fourier transform (FFT) algorithm to convert the acquired audio file into a frequency domain, thereby obtaining a frequency distribution characteristic. Under a quiet environment, the characteristic values of sound generated when the mobile phone starts to play the vibration prompt information are 260Hz, 518Hz and 775Hz, and the frequency spectrum fluctuation of the mobile phone on different material surfaces (such as wood, plastic, glass and the like) is +/-10 Hz, so that the prompt information is taken as the vibration prompt information as an example, if the frequency spectrum characteristic values of the current scene audio file are within 250 Hz-270 Hz, 508 Hz-528 Hz and 765 Hz-785 Hz, the current environment where the mobile terminal is located is the quiet environment; if the frequency spectrum characteristic value of the current scene audio file is not within 250 Hz-270 Hz, 508 Hz-528 Hz and 765 Hz-785 Hz, the current environment where the mobile terminal is located is a noisy environment.

Specifically, if the target spectrum characteristic value is not within the preset spectrum characteristic value range, it indicates that the mobile terminal is currently in the noisy environment, and the preset volume value needs to be adjusted, so that the user can hear the sound emitted by the terminal in the noisy environment. The adjustment mode can be that the maximum amplitude value of a preset audio file recorded by the mobile terminal in a quiet environment is searched, and the maximum decibel value of the audio file coding mode is determined. For example: if the maximum amplitude of the audio file is preset to be A and the encoding mode of the audio file is PCM-8 BIT, it can be determined that the maximum decibel value allowed by the encoding mode is 27128, the ratio of the maximum decibel value to the maximum amplitude value is determined to be
