步骤101，获取当前的播放条件；
步骤102：根据所获取的播放条件，判断是否符合HiFi播放功能要求；如果符合，则进行步骤103；如果不符合，则进行步骤104；
步骤103，使用HiFi播放功能，播放要播放的音源文件；
步骤104，关闭HiFi播放功能，采用普通播放功能播放要播放的音源文
件。
其中，步骤103使用HiFi播放功能，是指使用HiFi芯片解码输出高质量音频。
步骤101中要获取的当前播放条件，包括：
当前选定的音频输出设备是否支持HiFi播放和要播放的音源文件是否符合HiFi播放的音质要求。
步骤102判断是否符合HiFi播放功能要求，包括：
当所述当前选定的音频输出设备不支持HiFi播放时，判定为不符合HiFi播放功能要求；

或者，结合主流外接耳机或音响设备普通能够达到HiFi播放效果的情
况，简化判断流程为：
当选定的音频输出设备为外接的耳机或音响设备时，则确定该设备支持HiFi播放。
判断要播放的音源文件是否符合HiFi播放的音质要求，表示通过检测音源文件的一个或多个属性，判定音源文件的音质，当音源文件音质好时，使用HiFi播放功能才有实际意义，用户才能听到高保真的播放效果，当音源文件本身音质不好时，即使使用HiFi播放，由于音源文件的限制，用户也无法听到高保真的播放效果，这时，则无需使用HiFi播放功能，使用普通播放。
包括：
将所述音源文件的以下属性中的至少一个与设定的相应标准进行比较后确定是否符合HiFi播放的音质要求；
所述属性包括：采样精度、采样频率和位速。
其中，采样精度决定了记录声音的动态范围，也称为采样位数，它以位(Bit)为单位，如8bit，16bit；8bit可以把声波分为256级，16位可以把声波分为65536级的信号，位数越高，声音的保真度越高；
采样频率，称为采样速度或采样率，定义了每秒从连续的信号中提取并组成离散信号的采样个数，用赫兹(Hz)来表示。通俗的讲采样频率是指计算机每秒采集多少个声音样本，是衡量音源文件的质量标准，采样频率越高声音的还原就越真实自然，声音的保真度就越高；
位速，是指在一个数据流中每秒中能通过的信息量，如音频文件用“128–Kbps MP3”或“64–Kbps WMA”进行描述的情形。Kbps表示“每秒千字节数”，因此数值越大表示数据越多，信息量越大，音质就越好。
对该判定过程举例说明如下：
以采样精度为标准，判断音源文件音质，预设标准为：采样精度等于1bit或大于等于20bit，表示采样精度等于1bit，或者采样精度大于等于20bit的音源文件符合HiFi播放的音质要求；例如，DSD(Direct Stream Digital，直接比特流数字)格式的音源文件，其采样精度等于1bit，是一种成熟的高
音质音源文件。

以位速为标准，判断音源文件音质，预设标准为：位速大于等于1024kpbs，表示位速大于等于1024kpbs的音源文件符合HiFi播放的音质要求。
以采样精度、采样频率和位速为标准，判断音源文件音质，预设标准为：采样精度大于等于16bit，采样频率大于等于44.1kHz和位速大于等于1000kbps这三个条件中至少满足两个(即表示三个属性中至少有两项大于等于设定阈值)，表示当采样精度大于等于16bit且采样频率大于等于44.1kHz的音源文件符合HiFi播放的音质要求；或者，采样精度大于等于16bit且位速大于等于1000kbps的音源文件符合HiFi播放的音质要求；或者，采样频率大于等于44.1kHz且位速大于等于1000kbps的音源文件符合HiFi播放的音质要求；或者，采样精度大于等于16bit且采样频率大于等于44.1kHz且位速大于等于1000kbps的音源文件符合HiFi播放的音质要求。
或者，以采样精度、采样频率和位速为标准，判断音源文件音质，预设标准为：采样精度等于1bit的音源文件符合HiFi播放的音质要求；采样精度不等于1bit时，采样精度大于等于16bit，采样频率大于等于44.1kHz和位速大于等于1000kbps这三个条件中至少满足两个(即表示三个属性中至少有两项大于等于设定阈值)，表示当采样精度大于等于16bit且采样频率大于等于44.1kHz的音源文件符合HiFi播放的音质要求；或者，采样精度大于等于16bit且位速大于等于1000kbps的音源文件符合HiFi播放的音质要求；或者，采样频率大于等于44.1kHz且位速大于等于1000kbps的音源文件符合HiFi播放的音质要求；或者，采样精度大于等于16bit且采样频率大于等于44.1kHz且位速大于等于1000kbps的音源文件符合HiFi播放的音质要求。
本发明实施例中，判断标准中设定的比较阈值，不限于本实施例所例举的数值，可以根据实际音源文件的音质判断的需要相应确定其他数值。

可选的，
设备检测子模块211是设置为：
获取所需选定的音频输出设备的硬件参数，根据硬件参数确定是否支持HiFi播放；
或者，在当选定的音频输出设备为终端集成的喇叭时，确定该音频输出设备不支持HiFi播放；
或者，当选定的音频输出设备为外接的耳机或音响设备时，确定该音频输出设备支持HiFi播放。
所述音质检测子模块212，是设置为：获取所述音源文件的以下属性中的至少一个，将所获得的属性值与预设的相应标准进行比较后确定是否适合符合HiFi播放的音质要求；
所述属性包括：采样精度、采样频率和位速。
其中，音源文件的属性与设定的相应标准进行比较，确定是否符合HiFi播放的音质要求的过程，参见实施一中举例内容。
本领域普通技术人员可以理解上述实施例的全部或部分步骤可以使用计算机程序流程来实现，所述计算机程序可以存储于一计算机可读存储介质中，所述计算机程序在相应的硬件平台上(如系统、设备、装置、器件等)执行，在执行时，包括方法实施例的步骤之一或其组合。
可选地，上述实施例的全部或部分步骤也可以使用集成电路来实现，这些步骤可以被分别制作成一个个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。
上述实施例中的装置/功能模块/功能单元可以采用通用的计算装置来实现，它们可以集中在单个的计算装置上，也可以分布在多个计算装置所组成的网络上。
上述实施例中的装置/功能模块/功能单元以软件功能模块的形式实现并作为独立的产品销售或使用时，可以存储在一个计算机可读取存储介质中。上述提到的计算机可读取存储介质可以是只读存储器，磁盘或光盘等。
本发明实施例通过检测当前的播放条件，判断是否符合HiFi播放功能的条件，并依此控制HiFi播放功能的使用和关闭，即有针对性地有选择地播放可以真正让用户听到HiFi播放效果的播放场景，避免了因设备或文件原因本身已不可能给用户提供HiFi播放效果的情况下盲目采用HiFi播放功能造成不必要的终端的功率消耗，达到了减少耗电，增强终端的续航能力的效果。
