具体实施方式
下面结合附图和实施例对本发明作进一步的详细说明。可以理解的是，此处所描述的具体实施例用于解释本发明，而非对本发明的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与本发明相关的部分而非全部结构。
图1是本发明实施例提供的一种音量调节方法的流程图，本实施例可适用于终端设备播放音源时进行音量调节的情况，该方法可以由本发明实施例提供的终端设备来执行，该终端设备的音量调节装置可采用软件和/或硬件的方式实现，如图1所示，本实施例提供的具体方案如下：
步骤S101、当检测到终端设备进行音源播放时，获取所述音源的音频信息。
终端设备可通过安装的第三方应用程序或系统自带的音视频播放软件进行音源的播放。其中，主要包括音源文件的获取、解码和输出等步骤。示例性的，获取到的音源文件可以是通过网络接收到的组播流，还可以是终端设备本地存储的音视频文件；获取到该音源文件后将其加载到内存缓冲区中；对加载到内 存缓冲区的音源文件进行解码，在解码开始之前，如果该音源文件同时包含有视频数据，需要进行音频数据和视频数据的分离，将分离后的音频数据输入至音频解码器，其中，音频解码器主要用于读取内存缓冲区中的音频数据，得到数字音频信号，并将该数字音频信号转换为模拟音频信号，终端设备的播放器件根据该模拟音频信号进行音频播放。在一个实施例中，当监听到音源播放事件被触发时，确定终端设备开始播放音源，其中，该触发事件可以是检测到的触摸屏中显示的播放按钮被按下，还可以是检测到终端设备的播放器件如喇叭开始播放声音时，确定终端设备进行音源播放。
当检测到终端设备进行音源播放时，获取所述音源的音频信息。在一个实施例中，可对音频解码器解码得到的数字音频信号进行取样，确定该音源对应的音频信息。在另一实施例中，还可以获取当前播放的音源的原始文件，通过对该原始文件的解析确定音源对应的音频信息。在另一实施例中，以Android系统为例，可通过android.media.MediaRecorder类或android.media.AudioRecord类获取音源的音频信息。
步骤S102、依据所述音频信息确定和所述音频信息对应的音频振幅。
振幅指物体震动过程中偏离原来位置的最大距离，人耳听到的声音的响度与音源的振幅相关，振幅越大响度越强。在一个实施例中，可对音频解码器解码得到的数字音频信号进行取样，获取预设时间段T内的振幅信息，其中，该振幅信息可有多个振幅值组成，依据得到的多个振幅值可相应的确定在该预设时间段T内播放的音源的振幅曲线。在另一实施例中，以Android系统为例，可通过android.media.MediaRecorder类或android.media.AudioRecord类获取音源的音频信息后得到对应的振幅大小。在另一实施例中，当步骤S101获取到的音频信息为音源对应的原始文件时，可通过对原始文件进行解析以得到对应的振幅大小。
在一个实施例中，当检测音源播放时，每隔预设时间(如1s、3s或10s)确定一次振幅，或者实时的，对音频信息的每一帧的振幅进行确定。具体的，所述获取所述音源的音频信息包括：获取所述音源的音频帧信息；相应的，依据所述音频信息确定所述音源的振幅包括：依据所述音频帧信息确定所述音源每一帧的振幅。示例性的，当检测到音源播放时，对音源文件进行解析得到音频帧序列，根据音频帧序列的每一帧确定对应的振幅。
步骤S103、依据所述音频振幅的大小分配不同的振幅调整系数，依据所述振幅调整系数对所述音频振幅进行调整。
在一个实施例中，可根据确定的音频振幅的大小确定对应的不同的振幅调整系数，依据所述振幅调整系数对所述音频振幅进行调整。在对音频振幅进行调节的过程中，可通过对包含音频信息的音源文件进行解析，对得到的音频数据中的表征振幅信息的数据进行修改，修改完毕后再进行封装，当缓冲到对应的音源文件并被播放时音频振幅相应的已被修改；还可以是，在音源播放的解码过程中，通过对得到的数字音频信号进行分析得到振幅数据，将该振幅数据乘以对应的调节系数以改变振幅大小，进而对音源的音量进行调节。由此，实现了不改变终端设备系统原有音量的前提下对音源音量的大小进行了调节，调节过程可以在音源文件未进入缓冲区前，以减少播放负载，也可以是针对缓冲区中的音源内容进行调节以提高调节效率。
具体的，所述依据所述音频振幅的大小分配不同的振幅调整系数包括：为大于第一预设阈值或小于第三预设阈值的音频振幅分配第一振幅调整系数，为小于或等于第一预设阈值大于第二预设阈值的音频振幅分配第二振幅调整系数，为小于或等于第二预设阈值大于第三预设阈值的音频振幅分配第三振幅调整系数，其中，所述第一振幅调整系数小于所述第二振幅调整系数，所述第二振幅调整系数小于所述第三振幅调整系数，示例性的，该第一振幅调整系数可以是1，第二振幅调整系数可以是2，第三振幅调整系数可以是1.5，第一振幅阈值可以是-3db，第二振幅阈值可以是-10db，第三振幅阈值可以是-50db，相应的，给出对应关系可以如下表所示：
表1
振幅 调节系数
大于-3db或小于-50db 1
小于-10db大于-50db 2
小于-3db大于-10db 1.5
如表1所示，当音频振幅大于-3db或小于-50db时，不对其增益进行调节；当振幅小于-3db大于-10db时，振幅为高振幅区，为其分配增益系数为1.5，当振幅小于-10db大于-50db时，为中振幅区，为其分配振幅系数为2以显著提高该部分振幅的振幅大小。由上述内容可知，当检测到终端设备播放音源时，对 音频振幅进行自动调节，以得到合适的输出音量，使得用户的听感更加，提高了音量调节效率。
在一个可能的实施例中，可根据音频信息中的最大振幅和平均振幅确定振幅调整系数，在根据振幅调整系数对音频振幅进行调整。示例性的，如果所述最大振幅和所述平均振幅的差值满足预设条件，则依据所述最大振幅和所述平均振幅确定振幅调节系数。示例性的，当最大振幅和平均振幅差值较大时(如0.2db)，未避免播放到较大振幅的音源时音量较大，对较高的振幅进行调节以的降低音量。可选的，若最大振幅和平均振幅之差不满足预设条件，即相差不大，则不对音源的振幅进行调节。
在一个可能的实施例中，还可以预先根据音频振幅以及终端设备当前的音量确定振幅调整系数，再依据该振幅调整系数对音频振幅进行调整，示例性的，终端设备由静音到最大音量总共分为18个可调等级，每个等级对应一个音量值。具体的对应关系如下表所示：
表2
振幅 音量值(等级) 调节系数
大于-3db 5 0.5
小于-3db大于-10db 15 0.8
小于-20db 18 2
如表2所示，当音频振幅大于-3db且当前终端设备音量值较低时，相应的设置调节系数为0.5将音频振幅较高部分降低；当音频振幅小于-3db大于-10db，且当前终端设备音量值适中时，相应的设置调节系数为0.8对位于中振幅区域的音频振幅进行微调；当音频振幅小于-20db且当前终端设备音量值较高时，相应的将音频振幅较低部分进行增大。
图2是本发明实施例提供的另一种音量调节方法的流程图，可选的，在所述依据所述音频振幅的大小分配不同的振幅调整系数之前，还包括：确定所述音频信息中满足预设频率的音频振幅；相应的，所述依据所述音频振幅的大小分配不同的振幅调整系数包括：为所述满足预设频率的音频振幅分配第一振幅调整系数。如图2所示，技术方案具体如下：
步骤S201、当检测到终端设备进行音源播放时，获取所述音源的音频信息。
步骤S202、依据所述音频信息确定和所述音频信息对应的音频振幅。
步骤S203、确定所述音频信息中满足预设频率的音频振幅，为所述满足预设频率的音频振幅分配第一振幅调整系数。
其中，该第一振幅调整系数可以是1，即不对音频振幅的大小进行调节。示例性的，该预设频率可以是300hz，即当检测到音频信息中存在固定频率300hz的振幅，则将其作为噪音，不对其进行振幅调整，以避免将噪音同步放大的问题，同时，也进一步提高了音量调节效率。
图3是本发明实施例提供的另一种音量调节方法的流程图，可选的，在所述依据所述音频振幅的大小分配不同的振幅调整系数之前，还包括：通过身份验证识别信息确定当前终端设备使用者的身份属性，依据所述身份属性确定对应的第一振幅调整信息；相应的，所述依据所述音频振幅的大小分配不同的振幅调整系数包括：依据所述音频振幅的大小、所述第一振幅调整信息确定对应的振幅调整系数。如图3所示，具体包括：
步骤S301、当检测到终端设备进行音源播放时，获取所述音源的音频信息。
步骤S302、依据所述音频信息确定和所述音频信息对应的音频振幅。
步骤S303、通过身份验证识别信息确定当前终端设备使用者的身份属性，依据所述身份属性确定对应的第一振幅调整信息。
在一个实施例中，可通过终端设备的指纹模组对当前用户进行识别，进而依据存储的用户身份属性，如职业、年龄、性别等确定对应的第一振幅调整信息，该第一振幅调整信息可以是一修正系数。示例性的，当确定出的用户年龄较小如小于15岁时，则对应的该第一振幅调整信息可以是0.8，即将原有确定出的振幅调整系数乘以0.8作为修正后的振幅调整系数。
步骤S304、依据所述音频振幅的大小、所述第一振幅调整信息确定对应的振幅调整系数，依据所述振幅调整系数对所述音频振幅进行调整。
由上述可知，在对音频振幅进行调整过程中参考了用户自身的属性，使得音量的调节更加符合用户需求，可根据不同用户适应性的进行调整。
图4是本发明实施例提供的另一种音量调节方法的流程图，可选的，在所述依据所述音频振幅的大小分配不同的振幅调整系数之前，还包括：确定终端设备播放器件的阻抗值，依据所述阻抗值确定对应的第二振幅调整信息；相应的，所述依据所述音频振幅的大小分配不同的振幅调整系数包括：依据所述音频振幅的大小、所述第二振幅调整信息确定对应的振幅调整系数。如图4所示， 具体包括：
步骤S401、当检测到终端设备进行音源播放时，获取所述音源的音频信息。
步骤S402、依据所述音频信息确定和所述音频信息对应的音频振幅。
步骤S403、确定终端设备播放器件的阻抗值，依据所述阻抗值确定对应的第二振幅调整信息。
在一个实施例中，可通过功放芯片检测终端设备中安装的播放器件(如：扬声器)的阻抗值，还可以是通过物理方式检测播放器件的阻抗。该第二振幅调整信息可以为一修正系数。
步骤S404、依据所述音频振幅的大小、所述第二振幅调整信息确定对应的振幅调整系数，依据所述振幅调整系数对所述音频振幅进行调整。
示例性的，假设播放器件的标称阻抗值为x，通过检测得到的阻抗值为1.2x，则相应的第二振幅调整信息可以是1.2，即在为音频振幅分配不同的振幅调整系数时，将分配的振幅调整系数均乘以1.2以作为调整后的振幅调整系数。
由上述可知，在对音源的振幅进行调节过程中，引入播放器件的阻抗值作为确定振幅调节系数的参量之一，避免了播放器件随播放时长的增加阻抗值越来越高进而对正常播放过程中的音量大小产生影响的问题，使得调节后的音量大小更佳符合用户需求，进一步提高了音量调节效果。
图5是本发明实施例提供的另一种音量调节方法的流程图，可选的，在所述依据所述音频振幅的大小分配不同的振幅调整系数之前，还包括：确定终端设备当前所处环境的噪声值，依据所述噪声值确定对应的第三振幅调整信息；相应的，所述依据所述音频振幅的大小分配不同的振幅调整系数包括：依据所述音频振幅的大小、所述第三振幅调整信息确定对应的振幅调整系数。如图5所示，具体包括：

步骤S502、依据所述音频信息确定和所述音频信息对应的音频振幅。
步骤S503、确定终端设备当前所处环境的噪声值，依据所述噪声值确定对应的第三振幅调整信息。
在一个实施例中，可通过终端设备安装的麦克风采集当前所处环境的噪音以确定对应的噪声值。该第三振幅调整信息可以为一修正系数。
步骤S504、依据所述音频振幅的大小、所述第三振幅调整信息确定对应的 振幅调整系数，依据所述振幅调整系数对所述音频振幅进行调整。
示例性的，假设终端设备在安静环境下的噪声值为y，终端设备处于户外或嘈杂环境中时，确定的噪声值为1.5y，则相应的第三振幅调整信息可以是1.5，即在为音频振幅分配不同的振幅调整系数时，将分配的振幅调整系数均乘以1.5以作为调整后的振幅调整系数。
由上论述可知，在对音频振幅进行调节过程中，考虑了噪声对终端设备音量的影响，将确定的噪声值作为确定振幅调节系数的参量之一，使得调节后的音量大小更佳符合用户需求，进一步提高了音量调节效果。
图6是本发明实施例提供的另一种音量调节方法的流程图，可选的，在所述依据所述音频振幅的大小分配不同的振幅调整系数之前，还包括：确定所述音源的音源类型，依据所述音源类型确定对应的第四振幅调整信息；相应的，所述依据所述音频振幅的大小分配不同的振幅调整系数包括：依据所述音频振幅的大小、所述第四振幅调整信息确定对应的振幅调整系数。如图6所示，具体包括：
步骤S601、当检测到终端设备进行音源播放时，获取所述音源的音频信息。
步骤S602、依据所述音频信息确定和所述音频信息对应的音频振幅。

步骤S604、依据所述音频振幅的大小、所述第四振幅调整信息确定对应的振幅调整系数，依据所述振幅调整系数对所述音频振幅进行调整。
由上述可知，在对音频振幅进行调整的过程中，引入了音源类型作为调整修正参量，使得音频振幅的调整更加合理。

步骤S704、依据所述振幅调整系数确定对应的音量调节信息，依据所述音量调节信息对终端设备当前的音量进行调节。
在一个实施例中，根据振幅调节系数确定对应的音量调节信息。示例性的，当振幅调节系数大于1时，则确定对应的音量增大信息，当振幅调节系数小于1时，则确定对应的音量减小信息。具体的，在一个实施例中，该音量增大或音量减小的信息为对应的目标音量值。示例性的，终端设备由静音到最大音量总共分为18个可调等级，每个等级对应一个音量值，该音量减小信息对应的目标音量值可以是3或4，该音量增大信息对应的目标音量值可以是14或15，当确定出的音源振幅偏小时，则相应的将音量值增大至14或15，当确定出的音源振幅偏大时，则相应的将音量值减小至3或4。在另一实施例中，该音量增大或音量减小的信息为对应的音量改变值。示例性的，终端设备由静音到最大音量总共分为18个可调等级，每个等级对应一个音量值，该音量增大信息和音量减小信息对应的音量改变值为3，例如，当前终端设备的音量值为10，当需要增大音量信息时，则在当前音量值的基础上增加3即采用第13级音量进行声音播放，当需要减小音量信息时，则在当前音量值的基础上减小3即采用第7级音量进行声音播放。可选的，在对终端设备的音量进行调节之前，还包括：确定该音源的播放时间，当播放时间大于预设时间时，如30s则采用依据所述音量增大信息或音量减小信息中的音量改变值对所述终端设备当前的音量值进行调节的方式，由此进一步提高了音量调节效率，降低了终端设备的能耗。
由此，在对音源的振幅进行调节的基础上，适应性的对终端设备的播放音量进行调节，进一步增强了调节效果，使得音源播放过程中的音量更佳适中，符合用户需求。
图8是本发明实施例提供的一种音量调节装置的结构框图，该装置用于执行上述实施例提供的音量调节方法，具备执行方法相应的功能模块和有益效果。如图8所示，该装置具体包括：获取模块101、振幅确定模块102、调整系数确定模块103和调整模块104。
其中，获取模块101，用于当检测到终端设备进行音源播放时，获取所述音源的音频信息。
终端设备可通过安装的第三方应用程序或系统自带的音视频播放软件进行音源的播放。其中，主要包括音源文件的获取、解码和输出等步骤。示例性的，获取到的音源文件可以是通过网络接收到的组播流，还可以是终端设备本地存储的音视频文件；获取到该音源文件后将其加载到内存缓冲区中；对加载到内存缓冲区的音源文件进行解码，在解码开始之前，如果该音源文件同时包含有视频数据，需要进行音频数据和视频数据的分离，将分离后的音频数据输入至音频解码器，其中，音频解码器主要用于读取内存缓冲区中的音频数据，得到数字音频信号，并将该数字音频信号转换为模拟音频信号，终端设备的播放器件根据该模拟音频信号进行音频播放。在一个实施例中，当监听到音源播放事件被触发时，确定终端设备开始播放音源，其中，该触发事件可以是检测到的触摸屏中显示的播放按钮被按下，还可以是检测到终端设备的播放器件如喇叭开始播放声音时，确定终端设备进行音源播放。
当检测到终端设备进行音源播放时，获取所述音源的音频信息。在一个实施例中，可对音频解码器解码得到的数字音频信号进行取样，确定该音源对应的音频信息。在另一实施例中，还可以获取当前播放的音源的原始文件，通过对该原始文件的解析确定音源对应的音频信息。在另一实施例中，以Android系统为例，可通过android.media.MediaRecorder类或android.media.AudioRecord类获取音源的音频信息。
振幅确定模块102，用于依据所述音频信息确定和所述音频信息对应的音频振幅。
振幅指物体震动过程中偏离原来位置的最大距离，人耳听到的声音的响度与音源的振幅相关，振幅越大响度越强。在一个实施例中，可对音频解码器解码得到的数字音频信号进行取样，获取预设时间段T内的振幅信息，其中，该振幅信息可有多个振幅值组成，依据得到的多个振幅值可相应的确定在该预设 时间段T内播放的音源的振幅曲线。在另一实施例中，以Android系统为例，可通过android.media.MediaRecorder类或android.media.AudioRecord类获取音源的音频信息后得到对应的振幅大小。在另一实施例中，当步骤S101获取到的音频信息为音源对应的原始文件时，可通过对原始文件进行解析以得到对应的振幅大小。
在一个实施例中，当检测音源播放时，每隔预设时间(如1s、3s或10s)确定一次振幅，或者实时的，对音频信息的每一帧的振幅进行确定。具体的，所述获取所述音源的音频信息包括：获取所述音源的音频帧信息；相应的，依据所述音频信息确定所述音源的振幅包括：依据所述音频帧信息确定所述音源每一帧的振幅。示例性的，当检测到音源播放时，对音源文件进行解析得到音频帧序列，根据音频帧序列的每一帧确定对应的振幅。
调整系数确定模块103，用于依据所述音频振幅的大小分配不同的振幅调整系数。
在一个实施例中，可根据确定的音频振幅的大小确定对应的不同的振幅调整系数，依据所述振幅调整系数对所述音频振幅进行调整。在对音频振幅进行调节的过程中，可通过对包含音频信息的音源文件进行解析，对得到的音频数据中的表征振幅信息的数据进行修改，修改完毕后再进行封装，当缓冲到对应的音源文件并被播放时音频振幅相应的已被修改；还可以是，在音源播放的解码过程中，通过对得到的数字音频信号进行分析得到振幅数据，将该振幅数据乘以对应的调节系数以改变振幅大小，进而对音源的音量进行调节。由此，实现了不改变终端设备系统原有音量的前提下对音源音量的大小进行了调节，调节过程可以在音源文件未进入缓冲区前，以减少播放负载，也可以是针对缓冲区中的音源内容进行调节以提高调节效率。
调整模块104，用于依据所述振幅调整系数对所述音频振幅进行调整。
