S14、将待播放音频数据发送至音频播放模块进行播放。S14. Send the audio data to be played to the audio playback module for playback.

例如，电子设备的操作系统存储有多种音效算法：立体声音效算法、重低音音效算法、摇滚音效算法、小房间音效算法、大房间音效算法、礼堂音效算法、清新田园风音效算法、热情沙漠风音效算法等。For example, the operating system of an electronic device stores a variety of sound effect algorithms: stereo sound effect algorithm, subwoofer sound effect algorithm, rock sound effect algorithm, small room sound effect algorithm, large room sound effect algorithm, auditorium sound effect algorithm, fresh pastoral sound effect algorithm, warm desert wind Sound algorithm, etc.

响应于音频播放请求，确定待播放的初始音频数据为xxx歌曲和初始音频数据的请求音效类型为立体声，从多种音效算法中确定与请求音效类型相匹配的目标音效算法为立体声音效算法，采用立体声音效算法对xxx歌曲进行音效处理，得到待播放音频数据，最后将待播放音频数据发送至音频播放模块进行播放，用户就可以听到带立体声音效的xxx歌曲。In response to the audio playback request, determine that the initial audio data to be played is the xxx song and the requested sound effect type of the initial audio data is stereo, and determine from a variety of sound effect algorithms that the target sound effect algorithm that matches the requested sound effect type is a stereo sound effect algorithm, using The stereo sound effect algorithm performs sound effect processing on the xxx song to obtain audio data to be played, and finally sends the audio data to be played to the audio playback module for playback, and the user can hear the xxx song with stereo sound effect.

本实施例通过确定待播放的初始音频数据及其请求音效类型，从操作系统存储的多种音效算法中确定与请求音效类型相匹配的目标音效算法，采用目标音效算法对初始音频数据进行音效处理，得到待播放音频数据进行播放，支持应用层的各个平台从操作系统调用音效算法，实现系统内置音效，即实现音效在车辆控制系统内全局生效，实现各个平台音效统一。In this embodiment, by determining the initial audio data to be played and its requested sound effect type, a target sound effect algorithm that matches the requested sound effect type is determined from various sound effect algorithms stored in the operating system, and the target sound effect algorithm is used to perform sound effect processing on the initial audio data , obtain the audio data to be played, and support each platform of the application layer to call the sound effect algorithm from the operating system to realize the built-in sound effect of the system, that is, to realize the global effect of the sound effect in the vehicle control system, and to realize the unified sound effect of each platform.

由于支持应用层的各个平台从操作系统调用音效算法，应用层的各个平台无需自己部署音效算法，在需要使用音效算法处理播放音频数据时，可以从操作系统调用音效算法对音频数据进行音效处理并播放。Since each platform that supports the application layer calls the sound effect algorithm from the operating system, each platform of the application layer does not need to deploy the sound effect algorithm by itself. play.

具体实施时，每一音效算法设有对应的音效标识，电子设备还存储有音效类型与音效算法的对应关系。其中，音效标识为操作系统中的参数UUID，UUID的值表征对应的音效算法。During specific implementation, each sound effect algorithm is provided with a corresponding sound effect identifier, and the electronic device also stores the corresponding relationship between the sound effect type and the sound effect algorithm. Wherein, the sound effect identifier is a parameter UUID in the operating system, and the value of the UUID represents the corresponding sound effect algorithm.

参照图2，步骤S11包括：With reference to Fig. 2, step S11 comprises:

S111、响应于音频播放请求，从音频播放请求中获取待播放的初始音频数据和初始音频数据的请求音效类型。S111. In response to the audio play request, acquire initial audio data to be played and a requested sound effect type of the initial audio data from the audio play request.

音频播放请求可以但不限于是用户通过各个平台选择预播放的音频和音频类型而生成的，生成的音频播放请求携带对应于预播放的音频的初始音频数据和音频类型，或者音频播放请求携带对应于预播放的音频的音频获取地址和音频类型，例如：用户在音频播放请求中请求使用音效类型“立体声”播放音频“xxx歌曲”，或者用户在音频播放请求中请求使用音效类型“立体声”播放www网址的音频“xxx歌曲”。The audio playback request can be, but not limited to, generated by the user selecting the pre-played audio and audio type through each platform, and the generated audio playback request carries the initial audio data and audio type corresponding to the pre-played audio, or the audio playback request carries the corresponding The audio acquisition address and audio type of the pre-played audio, for example: the user requests to use the sound effect type "stereo" to play the audio "xxx song" in the audio play request, or the user requests to use the sound effect type "stereo" to play in the audio play request Audio "xxx song" from www url.

步骤S12包括：Step S12 includes:

S121、从操作系统获取请求音效类型与音效标识的对应关系。S121. Obtain the correspondence between the requested sound effect type and the sound effect identifier from the operating system.

请求音效类型与音效标识的对应关系可以根据实际需求自行配置，并将配置好的对应关系存储于操作系统，以供音效处理时使用。The corresponding relationship between the requested sound effect type and the sound effect identifier can be configured according to actual needs, and the configured corresponding relationship can be stored in the operating system for use in sound effect processing.

S122、根据对应关系，确定对应于请求音效类型的目标音效标识，以目标音效标识对应的音效算法作为目标音效算法。S122. Determine the target sound effect identifier corresponding to the requested sound effect type according to the corresponding relationship, and use the sound effect algorithm corresponding to the target sound effect identifier as the target sound effect algorithm.

例如，假设UUID的值为10的音效算法为立体声音效算法，响应于音频播放请求，从音频播放请求中获取待播放的初始音频数据为xxx歌曲以及初始音频数据的请求音效类型为立体声，从操作系统获取请求音效类型与音效标识的对应关系，根据对应关系，确定对应于请求音效类型的目标音效标识为10，目标音效标识为10对应的音效算法为立体声音效算法，以立体声音效算法作为目标音效算法，采用立体声音效算法对xxx歌曲进行音效处理，得到待播放音频数据，最后将待播放音频数据发送至音频播放模块进行播放，用户就可以听到带立体声音效的xxx歌曲。For example, assuming that the sound effect algorithm whose UUID value is 10 is a stereo sound effect algorithm, in response to the audio play request, the initial audio data to be played is obtained from the audio play request as xxx song and the requested sound effect type of the initial audio data is stereo, from the operation The system obtains the corresponding relationship between the requested sound effect type and the sound effect identifier, and according to the corresponding relationship, determines that the target sound effect identifier corresponding to the requested sound effect type is 10, and the sound effect algorithm corresponding to the target sound effect identifier of 10 is a stereo sound effect algorithm, and the stereo sound effect algorithm is used as the target sound effect The algorithm uses the stereo sound effect algorithm to perform sound effect processing on the xxx song to obtain the audio data to be played, and finally sends the audio data to be played to the audio playback module for playback, and the user can hear the xxx song with stereo sound effect.

本实施例通过从音频播放请求中获取待播放的初始音频数据及其请求音效类型，根据请求音效类型与音效标识的对应关系，确定对应于请求音效类型的目标音效标识，以目标音效标识对应的音效算法作为目标音效算法，采用目标音效算法对初始音频数据进行音效处理，得到待播放音频数据进行播放，支持应用层的各个平台从操作系统调用音效算法，实现系统内置音效，即实现音效在车辆控制系统内全局生效，实现各个平台音效统一。In this embodiment, the initial audio data to be played and the requested sound effect type are obtained from the audio playback request, and the target sound effect identifier corresponding to the requested sound effect type is determined according to the corresponding relationship between the requested sound effect type and the sound effect identifier, and the target audio effect identifier corresponding to the target audio effect identifier is determined. The sound effect algorithm is used as the target sound effect algorithm. The target sound effect algorithm is used to perform sound effect processing on the initial audio data, and the audio data to be played is obtained for playback. It supports each platform of the application layer to call the sound effect algorithm from the operating system to realize the built-in sound effect of the system, that is, to realize the sound effect in the vehicle. The control system takes effect globally to realize the unified sound effect of each platform.

具体实施时，在调用操作系统存储的音效算法之前，通过反射机制将目标音效标识的值写入操作系统的AudioEffect的实例中，修改后的AudioEffect的实例用于被操作系统和/或电子设备的应用程序调用，以对初始音频数据进行音效处理。During specific implementation, before calling the sound effect algorithm stored by the operating system, the value of the target sound effect identifier is written into the instance of the AudioEffect of the operating system through a reflection mechanism, and the modified AudioEffect instance is used by the operating system and/or the electronic device Called by the application to perform sound effects processing on raw audio data.

其中，由于AudioEffect的实例是隐藏不公开的，操作系统管理音效标识(UUID)，如果不是基于Framework层编译的应用程序均无法将自定义的目标音效标识的值写入操作系统的AudioEffect的实例中，从而无法完成设置自定义音效算法。Among them, since the instance of AudioEffect is hidden and undisclosed, the operating system manages the audio effect identifier (UUID), and the application program compiled based on the Framework layer cannot write the value of the customized target audio effect identifier into the instance of AudioEffect of the operating system , so that the setting of the custom sound effect algorithm cannot be completed.

以Java为例，Java反射机制是在运行状态中，对于任意一个类，都能够知道这个类的所有属性和方法；对于任意一个对象，都能够调用它的任意一个方法和属性；这种动态获取的信息以及动态调用对象的方法的功能称为java语言的反射机制(注意关键词：运行状态)换句话说，Java程序可以加载一个运行时才得知名称的class，获悉其完整构造，并生成其对象实体、或对其成员变量赋值、或调用其方法。这种“看透class”的能力称为反射。Taking Java as an example, the Java reflection mechanism is in the running state. For any class, you can know all the properties and methods of this class; for any object, you can call any of its methods and properties; this dynamic acquisition The information and the function of dynamically calling the method of the object are called the reflection mechanism of the java language (note the keyword: running state). In other words, a Java program can load a class whose name is known only at runtime, learn its complete structure, and generate Its object entities, or assign values to its member variables, or call its methods. This ability to "see through classes" is called reflection.

在本实施例中，通过反射机制将目标音效标识的值写入操作系统的AudioEffect的实例中，修改后的AudioEffect的实例可以被操作系统调用，也可以被电子设备的应用程序调用，来对初始音频数据进行音效处理。In this embodiment, the value of the target sound effect identifier is written into the AudioEffect instance of the operating system through the reflection mechanism, and the modified AudioEffect instance can be called by the operating system or by the application program of the electronic device to update the initial The audio data is processed with sound effects.

具体实施时，参照图3，在步骤S12之后，音效处理方法还包括：During specific implementation, with reference to Fig. 3, after step S12, the sound effect processing method also includes:

S15、将目标音效算法设置为默认音效算法。S15. Set the target sound effect algorithm as a default sound effect algorithm.

S16、在当前接收到的音频播放请求包括初始音频数据并且不包括请求音效类型时，采用默认音效算法对初始音频数据进行音效处理，得到待播放音频数据。S16. When the currently received audio playback request includes initial audio data and does not include the requested sound effect type, perform sound effect processing on the initial audio data by using a default sound effect algorithm to obtain audio data to be played.

本实施例中，在接收到的音频播放请求包括请求音效类型时，会将该请求音效类型对应的目标音效算法设置为默认音效算法，使用默认音效算法进行音效处理，如果后续的音频播放请求都不包括请求音效类型，即不发起变更默认音效算法，那么操作系统会一直保持默认音效算法不变，始终使用默认音效算法进行音效处理。In this embodiment, when the received audio playback request includes the requested sound effect type, the target sound effect algorithm corresponding to the requested sound effect type will be set as the default sound effect algorithm, and the default sound effect algorithm will be used for sound effect processing. If the requested sound effect type is not included, that is, if the default sound effect algorithm is not changed, the operating system will always keep the default sound effect algorithm unchanged, and always use the default sound effect algorithm for sound effect processing.

在一个实施例中，电子设备为车载终端，参照图4，音效处理方法还包括：In one embodiment, the electronic device is a vehicle-mounted terminal. Referring to FIG. 4, the sound effect processing method further includes:

S17、获取车载终端所属于的车辆的当前道路信息。S17. Obtain current road information of the vehicle to which the vehicle-mounted terminal belongs.

S18、在当前道路信息表征当前路段拥堵或路况湿滑时，选取默认音效算法为轻柔舒缓的音效算法。S18. When the current road information indicates that the current road section is congested or the road condition is slippery, select a soft and soothing sound effect algorithm as the default sound effect algorithm.

本实施例中，将音效处理方法应用到车载终端，在获取到的当前道路信息表征当前路段拥堵或路况湿滑时，选取默认音效算法为轻柔舒缓的音效算法，以缓解车辆内部人员由于路况导致的不良情绪。In this embodiment, the sound effect processing method is applied to the vehicle-mounted terminal. When the obtained current road information indicates that the current road section is congested or the road condition is wet and slippery, the default sound effect algorithm is selected as a soft and soothing sound effect algorithm, so as to relieve the pain caused by the road conditions caused by the personnel inside the vehicle. bad mood.

具体实施时，参照图5，音效处理方法还包括：During specific implementation, with reference to Fig. 5, the sound effect processing method also includes:

S19、获取播放记录。S19. Obtain a playback record.

S20、根据播放记录设置默认音效算法。S20. Set a default sound effect algorithm according to the playback record.

例如，根据电子设备的音效播放记录，将最近x天内使用次数最多的音效算法设置默认音效算法，或者，将最近x天内累计使用时长最长的音效算法设置默认音效算法，或者，将最近x天内单次使用时长最长的音效算法设置默认音效算法等。For example, according to the sound effect playback records of electronic devices, set the sound effect algorithm that has been used the most times in the last x days as the default sound effect algorithm, or set the sound effect algorithm that has been used for the longest cumulative time in the last x days as the default sound effect algorithm, or set the sound effect algorithm that has been used the most in the last x days The sound effect algorithm with the longest single use time sets the default sound effect algorithm, etc.

本实施例中，根据播放记录设置默认音效算法，即按照用户喜好和习惯进行设置，可以节省用户用于设置操作的时间。In this embodiment, the default sound effect algorithm is set according to the playback record, that is, the setting is performed according to the user's preferences and habits, which can save the user's time for setting operations.

例如，假设UUID的值为10的音效算法为立体声音效算法，响应于音频播放请求，从音频播放请求中获取待播放的初始音频数据为xxx歌曲以及初始音频数据的请求音效类型为立体声，从操作系统获取请求音效类型与音效标识的对应关系，根据对应关系，确定对应于请求音效类型的目标音效标识为10，目标音效标识为10对应的音效算法为立体声音效算法，以立体声音效算法作为目标音效算法，采用立体声音效算法对xxx歌曲进行音效处理，得到待播放音频数据，最后将待播放音频数据发送至音频播放模块进行播放，用户就可以听到带立体声音效的xxx歌曲。For example, assuming that the sound effect algorithm whose UUID value is 10 is a stereo sound effect algorithm, in response to the audio play request, the initial audio data to be played is obtained from the audio play request as xxx song and the requested sound effect type of the initial audio data is stereo, from the operation The system obtains the corresponding relationship between the requested sound effect type and the sound effect identifier, and according to the corresponding relationship, determines that the target sound effect identifier corresponding to the requested sound effect type is 10, and the sound effect algorithm corresponding to the target sound effect identifier of 10 is a stereo sound effect algorithm, and the stereo sound effect algorithm is used as the target sound effect The algorithm uses the stereo sound effect algorithm to perform sound effect processing on the xxx song to obtain the audio data to be played, and finally sends the audio data to be played to the audio playback module for playback, and the user can hear the xxx song with stereo sound effect.

本实施例通过从音频播放请求中获取待播放的初始音频数据及其请求音效类型，根据请求音效类型与音效标识的对应关系，确定对应于请求音效类型的目标音效标识，以目标音效标识对应的音效算法作为目标音效算法，采用目标音效算法对初始音频数据进行音效处理，得到待播放音频数据进行播放，支持应用层的各个平台从操作系统调用音效算法，实现系统内置音效，即实现音效在车辆控制系统内全局生效，实现各个平台音效统一。In this embodiment, the initial audio data to be played and the requested sound effect type are obtained from the audio playback request, and the target sound effect identifier corresponding to the requested sound effect type is determined according to the corresponding relationship between the requested sound effect type and the sound effect identifier, and the target audio effect identifier corresponding to the target audio effect identifier is determined. The sound effect algorithm is used as the target sound effect algorithm. The target sound effect algorithm is used to perform sound effect processing on the initial audio data, and the audio data to be played is obtained for playback. It supports each platform of the application layer to call the sound effect algorithm from the operating system to realize the built-in sound effect of the system, that is, to realize the sound effect in the vehicle. The control system takes effect globally to realize the unified sound effect of each platform.

具体实施时，处理器通过反射机制将目标音效标识的值写入操作系统的AudioEffect的实例中，修改后的AudioEffect的实例用于被操作系统和/或电子设备的应用程序调用，以对初始音频数据进行音效处理。During specific implementation, the processor writes the value of the target sound effect identifier into the instance of the AudioEffect of the operating system through the reflection mechanism, and the modified instance of AudioEffect is used to be called by the operating system and/or the application program of the electronic device to modify the original audio The data is processed with sound effects.

其中，由于AudioEffect的实例是隐藏不公开的，操作系统管理音效标识(UUID)，如果不是基于Framework层编译的应用程序均无法将自定义的目标音效标识的值写入操作系统的AudioEffect的实例中，从而无法完成设置自定义音效算法。Among them, since the instance of AudioEffect is hidden and undisclosed, the operating system manages the audio effect identifier (UUID), and the application program compiled based on the Framework layer cannot write the value of the customized target audio effect identifier into the instance of AudioEffect of the operating system , so that the setting of the custom sound effect algorithm cannot be completed.

以Java为例，Java反射机制是在运行状态中，对于任意一个类，都能够知道这个类的所有属性和方法；对于任意一个对象，都能够调用它的任意一个方法和属性；这种动态获取的信息以及动态调用对象的方法的功能称为java语言的反射机制(注意关键词：运行状态)换句话说，Java程序可以加载一个运行时才得知名称的class，获悉其完整构造，并生成其对象实体、或对其成员变量赋值、或调用其方法。这种“看透class”的能力称为反射。Taking Java as an example, the Java reflection mechanism is in the running state. For any class, you can know all the properties and methods of this class; for any object, you can call any of its methods and properties; this dynamic acquisition The information and the function of dynamically calling the method of the object are called the reflection mechanism of the java language (note the keyword: running state). In other words, a Java program can load a class whose name is known only at runtime, learn its complete structure, and generate Its object entities, or assign values to its member variables, or call its methods. This ability to "see through classes" is called reflection.

在本实施例中，通过反射机制将目标音效标识的值写入操作系统的AudioEffect的实例中，修改后的AudioEffect的实例可以被操作系统调用，也可以被电子设备的应用程序调用，来对初始音频数据进行音效处理。In this embodiment, the value of the target sound effect identifier is written into the AudioEffect instance of the operating system through the reflection mechanism, and the modified AudioEffect instance can be called by the operating system or by the application program of the electronic device to update the initial The audio data is processed with sound effects.

具体实施时，在处理器从多种音效算法中确定与请求音效类型相匹配的目标音效算法之后，处理器将目标音效算法设置为默认音效算法。During specific implementation, after the processor determines a target sound effect algorithm that matches the requested sound effect type from multiple sound effect algorithms, the processor sets the target sound effect algorithm as a default sound effect algorithm.

在处理器当前接收到的音频播放请求包括初始音频数据并且不包括请求音效类型时，处理器采用默认音效算法对初始音频数据进行音效处理，得到待播放音频数据。When the audio playback request currently received by the processor includes initial audio data and does not include the requested sound effect type, the processor uses a default sound effect algorithm to perform sound effect processing on the initial audio data to obtain audio data to be played.

本实施例中，在接收到的音频播放请求包括请求音效类型时，会将该请求音效类型对应的目标音效算法设置为默认音效算法，使用默认音效算法进行音效处理，如果后续的音频播放请求都不包括请求音效类型，即不发起变更默认音效算法，那么操作系统会一直保持默认音效算法不变，始终使用默认音效算法进行音效处理。In this embodiment, when the received audio playback request includes the requested sound effect type, the target sound effect algorithm corresponding to the requested sound effect type will be set as the default sound effect algorithm, and the default sound effect algorithm will be used for sound effect processing. If the requested sound effect type is not included, that is, if the default sound effect algorithm is not changed, the operating system will always keep the default sound effect algorithm unchanged, and always use the default sound effect algorithm for sound effect processing.

具体实施时，电子设备为车载终端，处理器获取车载终端所属于的车辆的当前道路信息。During specific implementation, the electronic device is a vehicle-mounted terminal, and the processor acquires current road information of the vehicle to which the vehicle-mounted terminal belongs.

在当前道路信息表征当前路段拥堵或路况湿滑时，处理器选取默认音效算法为轻柔舒缓的音效算法。When the current road information indicates that the current road section is congested or the road condition is wet and slippery, the processor selects the default sound effect algorithm as a soft and soothing sound effect algorithm.

本实施例中，将音效处理方法应用到车载终端，在获取到的当前道路信息表征当前路段拥堵或路况湿滑时，选取默认音效算法为轻柔舒缓的音效算法，以缓解车辆内部人员由于路况导致的不良情绪。In this embodiment, the sound effect processing method is applied to the vehicle-mounted terminal. When the obtained current road information indicates that the current road section is congested or the road condition is wet and slippery, the default sound effect algorithm is selected as a soft and soothing sound effect algorithm, so as to relieve the pain caused by the road conditions caused by the personnel inside the vehicle. bad mood.

具体实施时，处理器获取播放记录。During specific implementation, the processor acquires the playback record.

处理器根据播放记录设置默认音效算法。The processor sets the default sound effect algorithm according to the playback record.

例如，根据电子设备的音效播放记录，将最近x天内使用次数最多的音效算法设置默认音效算法，或者，将最近x天内累计使用时长最长的音效算法设置默认音效算法，或者，将最近x天内单次使用时长最长的音效算法设置默认音效算法等。For example, according to the sound effect playback records of electronic devices, set the sound effect algorithm that has been used the most times in the last x days as the default sound effect algorithm, or set the sound effect algorithm that has been used for the longest cumulative time in the last x days as the default sound effect algorithm, or set the sound effect algorithm that has been used the most in the last x days The sound effect algorithm with the longest single use time sets the default sound effect algorithm, etc.

本实施例中，根据播放记录设置默认音效算法，即按照用户喜好和习惯进行设置，可以节省用户用于设置操作的时间。In this embodiment, the default sound effect algorithm is set according to the playback record, that is, the setting is performed according to the user's preferences and habits, which can save the user's time for setting operations.

具体实施时，音效处理方法还包括：During specific implementation, the sound effect processing method also includes:

通过云服务端更新音效算法。Update the sound effect algorithm through the cloud server.

本实施例可以对自定义的音效算法进行更新，提供了丰富操作系统存储的音效算法的一种具体实施方式。This embodiment can update the self-defined sound effect algorithm, and provides a specific implementation manner of enriching the sound effect algorithm stored in the operating system.
