下面对本发明方法实施例进行描述。
请参阅图1，图1是本发明实施例公开的一种音量处理方法的流程示意图。该方法可由装置实施例中描述的用户终端实现。如图1所示，该方法可包括以下步骤。
步骤S101，记录所述音频文件的初始音量输出值为第一输出值。
在一个实施例中，当音频文件需要添加音效时，可记录该音频文件的初始音量输出值为第一输出值。具体的，当用户终端开启需要添加音效的音频文件时，或者用户终端当前正在播放音频文件，当检测到对该音频文件添加音效的操作后，可记录该音频文件的初始音量输出值，并将该音频文件的初始音量输出值作为第一输出值。
步骤S102，当在所述音频文件上添加音效参数时，预先将所述音频文件的音量输出值降低为第二输出值。
在一个实施例中，当在所述音频文件上添加音效参数时，可预先将该音频文件的音量输出值降低为第二输出值。具体的，当需要在该音频文件上添加音效参数时，可预先将该音频文件的音量输出值降低，避免音效突然添加导致的音量输出值过高，影响用户听觉舒适度。其中，将音频文件的音量输出值降低为第二输出值，该第二输出值可为最小输出值，如最小输出值为零；或者，该第二输出值可基于预设的音量增加模型进行确定；或者，该第二输出值可基于当前需要添加的音效参数的音效强度进行确定，若需要添加的音效参数的音效强度强，则该第二输出值相对较小，若需要添加的音效参数的音效强度弱，则该第二输出值相对较大；或者，该第二输出值可基于预设的噪音阈值进行确定，当预设音量输出值的噪音阈值后，第二输出值可确定为小于该噪音阈值的任何值。可选的，噪音阈值能够根据上述音频文件的音频类型或者用户习惯的音量输出值确定，音频类型为摇滚类型，则噪音阈值可预设的相对较高，音频类型为轻音乐类型，则噪音阈值可预设的相对较低；或者用户习惯的音量较大，则噪音阈值可预设的相对较高，用户习惯的音量较小，则噪音阈值可预设的相对较低。
步骤S103，在所述音效参数添加后，将所述音量输出值按照音量增加模型从所述第二输出值逐级调节至所述第一输出值。
在一个实施例中，在音频文件上添加音效参数时，可预先将该音频文件的音量输出值降低至第二输出值，并可按照音量增加模型从第二输出值逐级调节至第一输出值，即将该音频文件降低的音量输出值逐渐恢复至未添加音效参数的初始音量输出值。具体的，将音量输出值按照音量增加模型进行调节，该音量增加模型可为预设的音量增加模型，也可根据不同的音效参数确定不同的音量增加模型。该音量增加模型可为音效参数的添加时长与音量输出值的对应关系曲线，该对应关系曲线可为一次正相关曲线，也可为指数增长曲线或对数增长曲线等，在此，本发明实施例不做限定。或者该音量增加模型也可为音效参数的音效强度与音量输出值的对应关系曲线，随着音效参数的音效强度的逐步增强，音频文件的音量输出值也逐步增强。需要说明的是，本发明实施例并不限定音量输出值在音效参数的添加时长内恢复至第一输出值，音量输出值可在超过上述添加时长的时间内恢复至第一输出值。
本发明实施例中，通过记录音频文件的初始音量输出值，并当在该音频文件上添加音效参数时，预先将该音频文件的音量输出值降低，避免音效增加导致的音量输出值过高，影响用户听觉舒适度。并在所述音效参数添加后，通过将音量输出值按照音量增加模型从降低的第二输出值逐级调节至第一输出值，可在添加音效时使音频文件的音量输出值进行平滑过渡，提升用户听觉舒适度，进而提升用户体验。
请参阅图2，图2是本发明实施例公开的另一种音量处理方法的流程示意图。该方法可由装置实施例中描述的用户终端实现。如图2所示，该方法可包括以下步骤。
步骤S201，记录所述音频文件的初始音量输出值为第一输出值。
在一个实施例中，当音频文件需要添加音效时，可记录该音频文件的初始音量输出值为第一输出值。具体的，当用户终端开启需要添加音效的音频文件时，或者用户终端当前正在播放音频文件，当检测到对该音频文件添加音效的操作后，可记录该音频文件的初始音量输出值，并将该音频文件的初始音量输出值作为第一输出值。
步骤S202，当在所述音频文件上添加音效参数时，预先将所述音频文件的音量输出值降低为第二输出值。
在一个实施例中，当在所述音频文件上添加音效参数时，可预先将该音频文件的音量输出值降低为第二输出值。具体的，当需要在该音频文件上添加音效参数时，可预先将该音频文件的音量输出值降低，避免音效增加导致的音量输出值过高，影响用户听觉舒适度。其中，将音频文件的音量输出值降低为第二输出值，该第二输出值可为最小输出值，如最小输出值为零；或者，该第二输出值可基于预设的音量增加模型进行确定；或者，该第二输出值可基于当前需要添加的音效参数的音效强度进行确定，若需要添加的音效参数的音效强度强，则该第二输出值相对较小，若需要添加的音效参数的音效强度弱，则该第二输出值相对较大；或者，该第二输出值可基于预设的噪音阈值进行确定，当预设音量输出值的噪音阈值后，第二输出值可确定为小于该噪音阈值的任何值。可选的，噪音阈值能够根据上述音频文件的音频类型或者用户习惯的音量输出值确定，音频类型为摇滚类型，则噪音阈值可预设的相对较高，音频类型为轻音乐类型，则噪音阈值可预设的相对较低；或者用户习惯的音量较大，则噪音阈值可预设的相对较高，用户习惯的音量较小，则噪音阈值可预设的相对较低。
步骤S203，获取所述音效参数的音效强度。
在一个实施例中，在该音频文件上添加音效参数的同时，还可获取该音效参数的音效强度。具体的，可通过获取该音效参数的音效强度，基于该音效强度确定第一音量增加模型。其中，音效参数可包括多个音效参数，每个音效参数对应音效强度，可通过检测各音效参数的大小，可整体确定待添加音效参数的音效强度；也可通过确定各音效参数的权重，确定各音效参数对应的音效强度占总体音效强度的比例，进而确定待添加的音效参数的音效强度。当然，还可基于各音效参数对应的音效强度，确定第一音量增加量。
步骤S204，基于所述音效强度，确定与所述音效强度对应的第一音量增加模型。
在一个实施例中，当获取到音效参数的音效强度后，还可基于该音效强度，确定与该音效强度对应的第一音量增加模型。步骤S204可基于以下步骤实现：
在所述音效参数的添加时长内，采集n个预设周期时刻对应的n个音效强度，n为整数；
基于所述采集的n个音效强度，确定对应的n个音量增加量；
基于所述n个音量增加量确定所述第一音量增加模型。
具体的，在将音效参数添加至音频文件上的添加时长内，可采集n个音效强度，即音效参数与添加时长成映射关系，在添加时长的每个时刻，对应一个音效参数，该音效参数可与上一时刻相同，也可与上一时刻不同，形成音效参数曲线，而不同的音效参数，其音效强度也不同。可通过预设采集周期，采集音效参数曲线上的n个音效参数，进而能够获取该n个音效参数的音效强度。或者，当获取到上述音效参数曲线后，根据音效参数与音效强度的对应关系，获取音效强度相对于添加时长的音效强度曲线，即不同的添加时长内的添加时刻，对应可相同或不同的音效强度，进而通过预设的采集周期，采集音效强度曲线上的n个音效强度。
当确定n个音效强度后，可根据该n个音效强度，确定对应的n个音量增加量。具体的，音效强度可与音量增加量成正相关关系，也可与音量增加量成负相关关系。当音效强度与音量增加量成正相关关系时，音效强度越强，音量增加量越大，进而增强了音频文件的输出效果，提升用户体验；或者，当音效强度与音量增加量成负相关关系时，音效强度越强，音量增加量越小，进而平衡了音频文件的输出音量，使音频文件的输出音量更为平滑。上述两种模式还可基于音频文件的类型或者用户倾向的音量输出习惯进行确定，在此不做限定。
当确定n个音量增加量后，可基于该n个音量增加量建立音量增加模型。如通过统计n个音量增加量，确定n个音量增加量形成的曲线趋势，进而基于统计的n个音量增加量确定其对应的数学曲线，该数学曲线即为音量增加模型。
步骤S205，在所述音效参数添加后，将所述音量输出值按照所述第一音量增加模型从所述第二输出值逐级调节至所述第一输出值。
在一个实施例中，当通过上述方式确定第一音量增加模型后，可将音量输出值按照该第一音量增加模型从第二输出值逐级调节至第一输出值。当将音量输出值按照第一音量增加模式调节，并且，音量输出值可通过第一音量增加模型从第二输出值调节恢复至音频文件的初始音量输出值，即第一输出值时，既可避免添加音效时带来的音量输出增加造成的噪音影响，也可突出音频文件的播放效果或者使音频文件的音量输出更加平滑。
本发明实施例中，通过记录音频文件的初始音量输出值，并当在该音频文件上添加音效参数时，预先将该音频文件的音量输出值降低，避免音效增加导致的音量输出值过高，影响用户听觉舒适度。并在所述音效参数添加后，通过将音量输出值按照音量增加模型从降低的第二输出值逐级调节至第一输出值，可在添加音效时使音频文件的音量输出值进行平滑过渡，提升用户听觉舒适度，进而提升用户体验。
请参阅图3，图3是本发明实施例公开的又一种音量处理方法的流程示意图。该方法可由装置实施例中描述的用户终端实现。如图3所示，该方法可包括以下步骤。
步骤S301，记录所述音频文件的初始音量输出值为第一输出值。
在一个实施例中，当音频文件需要添加音效时，可记录该音频文件的初始 音量输出值为第一输出值。具体的，当用户终端开启需要添加音效的音频文件时，或者用户终端当前正在播放音频文件，当检测到对该音频文件添加音效的操作后，可记录该音频文件的初始音量输出值，并将该音频文件的初始音量输出值作为第一输出值。
步骤S302，当在所述音频文件上添加音效参数时，预先将所述音频文件的音量输出值降低为第二输出值。
在一个实施例中，当在所述音频文件上添加音效参数时，可预先将该音频文件的音量输出值降低为第二输出值。具体的，当需要在该音频文件上添加音效参数时，可预先将该音频文件的音量输出值降低，避免音效增加导致的音量输出值过高，影响用户听觉舒适度。其中，将音频文件的音量输出值降低为第二输出值，该第二输出值可为最小输出值，如最小输出值为零；或者，该第二输出值可基于预设的音量增加模型进行确定；或者，该第二输出值可基于当前需要添加的音效参数的音效强度进行确定，若需要添加的音效参数的音效强度强，则该第二输出值相对较小，若需要添加的音效参数的音效强度弱，则该第二输出值相对较大；或者，该第二输出值可基于预设的噪音阈值进行确定，当预设音量输出值的噪音阈值后，第二输出值可确定为小于该噪音阈值的任何值。可选的，噪音阈值能够根据上述音频文件的音频类型或者用户习惯的音量输出值确定，音频类型为摇滚类型，则噪音阈值可预设的相对较高，音频类型为轻音乐类型，则噪音阈值可预设的相对较低；或者用户习惯的音量较大，则噪音阈值可预设的相对较高，用户习惯的音量较小，则噪音阈值可预设的相对较低。
步骤S303，获取所述音效参数的音效模式。
在一个实施例中，当获取待添加的音效参数后，或可获取该音效参数的音效模式。具体的，该音效参数的音效模式可根据音效参数的变化程度确定，若音效参数的变化剧烈，则该音效参数的音效模式为强烈模式；若音效参数的变化平缓，则该音效参数的音效模式为平缓模式。或者，音效参数的音效模式还可结合音频文件进行确定，若音频文件的文件类型为摇滚类型等，则确定增加的音效参数的音效模式的强烈模式，若音频文件的文件类型为轻音乐类型等，则确定以增加的音效参数的音效模式为平缓模式等。
步骤S304，基于所述音效模式，确定与所述音效模式对应的第二音量增加模型。
在一个实施例中，当获取到上述音频参数的音效模式后，还可确定与该音效模式对应的第二音量增加模型。具体的，若确定音频参数的音效模式为平缓模式，则与其对应的第二音量增加模型可为对数增加模型；若确定音频参数的音效模式为强烈模式，则与其对应的第二音量增加模型可为指数增加模型。其中，若音效模式为平缓模式，则音量输出值可与该音效模式相匹配，音量输出值平缓增加进行输出，即在音效添加时长的预设时间补偿内，音量输出值增加的增加量较小；此时，可按照通用的对数增加模型进行音量输出，该对数增加模型可满足音量输出值平缓增加。若音效模式为强烈模式，则音量输出值可与 该音效模式相匹配，音量输出值可以大幅度增加等，即在音效添加时长的预设时间补偿内，音量输出值增加的增加量较大；此时，可按照通用的指数增加模型进行音量输出，该指数增加模型可满足音量输出值的大幅度增加。
步骤S305，在所述音效参数添加后，将所述音量输出值按照所述第二音量增加模型从所述第二输出值逐级调节至所述第一输出值。
在一个实施例中，可通过上述确定的第二音量增加模式调节音量输出值，使其从第二输出值上升至该音频文件的初始音量输出值，即第一输出值。通过音效参数对应的音效模式，可确定与该音效模式对应的第二音量增加模型，从而，音量输出值在避免输出噪声的同时，还能够匹配音效模式，增强音频文件的输出效果。
本发明实施例中，通过记录音频文件的初始音量输出值，并当在该音频文件上添加音效参数时，预先将该音频文件的音量输出值降低，避免音效增加导致的音量输出值过高，影响用户听觉舒适度。并在所述音效参数添加后，通过将音量输出值按照音量增加模型从降低的第二输出值逐级调节至第一输出值，可在添加音效时使音频文件的音量输出值进行平滑过渡，提升用户听觉舒适度，进而提升用户体验。
