作为一种可行的实施方式，终端设备在播放音频文件时，若音频文件的数据量较大，或者音频文件的时长较长，可将音频文件按照数据量或时长划分为至少两个音频片段。在播放一个音频片段之前，例如在播放上一个音频片段时，或者在处理音频播放请求时，终端设备可预先读取将要播放的音频片段，检测该音频片段的最大音量差。
S102，若所述最大音量差大于预设差值，确定所述音频片段中音量大于第一预设音量的第一子片段。
本发明实施例中，对于最大音量差大于预设差值的音频片段，还可进一步划分为多个子片段。可选地，若上述音频片段为按照数据量进行划分的，则可按照更小的数据量将上述音频片段划分为多个子片段，例如，可将一个数据量为200KB的音频片段划分为20个大小为10KB的子片段。若上述音频片段为按照时长划分的，则可按照更短的时长将上述音频片段划分为多个子片段，例如，可将一个时长为10s的音频片段划分为5个时长为2s的子片段。
作为一种可行的实施方式，终端设备可存储一预设差值，该预设差值可作为判断上述最大音量差是否达到触发条件的依据。若上述最大音量差大于该预设差值，可触发对上述音频片段的音量调节。
作为一种可行的实施方式，终端设备还可存储第一预设音量的值，第一预设音量的值大于上述最大音量差，例如，若上述最大音量差为70dB，则第一预设音量可以为90dB。本发明实施例中，当最大音量差大于预设差值，并且播放音频的音量大于第一预设音量时，认为音量的变化可能导致用户不适。此时，可从上述音频片段中确定音量大于第一预设音量的第一子片段。
S103，降低播放所述第一子片段的音量。
在一些可选实施例中，可根据所述音频片段的最大音量与所述第一预设音量之间的比值确定第一调节比例；按照所述第一调节比例降低播放所述第一子片段的音量。例如，若所述音频片段的最大音量与所述第一预设音量之间的比值为2:3，则可将播放所述第一子片段的音量调整为原音量的三分之二。
在一些可选实施例中，还可根据所述音频片段的最大音量与所述第一预设音量之间的差值确定第一调节量；按照所述第一调节量降低播放所述第一子片段的音量。例如，若上述音频片段的最大音量与所述第一预设音量之间的差值为10dB，则可将播放所述第一子片段的音量降低10dB。
具体实施中，第一子片段为音量大于第一预设音量的子片段，可能对用户听觉造成伤害。降低播放所述第一子片段的音量，不仅可保护用户的听觉，还可减少功耗。
本发明实施例中，在终端设备播放音频文件时，检测当前读取的所述音频文件的一音频片段的最大音量差，所述最大音量差为所述音频片段的最大音量与最小音量之间的差值；若所述最大音量差大于预设差值，确定所述音频片段中音量大于第一预设音量的第一子片段；降低播放所述第一子片段的音量。采用本发明实施例，可预先降低音频文件中音量过大的音频片段的播放音量，保护用户的听觉，并降低终端设备的音效功耗。

S204，确定所述音频片段中音量小于第二预设音量的第二子片段。
作为一种可行的实施方式，终端设备可存储第二预设音量的值，第二预设音量的值小于第一预设音量的值。其中第二预设音量的值可以是预先设置的固定值，也可以根据当前环境噪音的音量实时设置并存储。若第二预设音量为根据环境噪音的音量设置的，第二预设音量值应大于当前环境噪音的音量。
发明实施例中，当播放音频的音量小于第二预设音量时，认为音量过小可能导致用户无法听清。此时，可从上述音频片段中确定音量小于第二预设音量的第二子片段。
S205，增大播放所述第二子片段的音量。
在一些可选实施例中，可根据所述音频片段的最小音量与所述第二预设音量之间的比值确定第二调节比例；以及，按照所述第二调节比例增大播放所述第二子片段的音量。例如，若所述音频片段的最小音量与所述第二预设音量之间的比值为2:3，则可将播放所述第二子片段的音量调整为原音量的1.5倍。
在一些可选实施例中，可根据所述音频片段的最小音量与所述第二预设音量之间的差值确定第二调节量；以及，按照所述第二调节量增大播放所述第二子片段的音量。例如，若所述音频片段的最小音量与所述第二预设音量之间的差值为10dB，则可将播放所述第二子片段的音量增大10dB。
