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效添加方法的流程示意图。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，获取需要添加音效的音频数据。
在一个实施例中，首先获取需要添加音效的音频数据。其中，该音频数据可从音频文件中获取，也可从视频文件中获取。本发明实施例不做限定。其中，该获取的音频数据为需要添加音效的音频数据，该音频数据可为音频文件或视频文件中的整体文件数据，也可为其中部分音频数据，即对原始的音频数据进 行截取等操作，以获取需要添加音效的音频数据。其中，该音频数据的时长可大于或等于待添加音效的添加时长。
步骤S102，将n组音效强度调节值依次添加至所述音频数据上，使得音频数据的音效逐渐增强至待添加音效的音效强度值，所述n为正整数。
可选的，步骤S102的具体实现方式可为：
将n组音效强度调节值依次且独立地添加至所述音频数据，所述n组音效强度调节值从弱到强变化，所述第n组音效强度调节值为所述待添加音效的音效强度值。
具体的，n组音效强度调节值的排序顺序为从弱到强，即第一组音效强度调节值最弱，例如为零，第n组音效强度调节值最强。并且，第n组音效强度调节值为待添加音效的音效强度值。其中，第一组音效强度调节值的确定以及n的数值可根据音频数据的输出效果的强度等级决定，若音频数据输出效果的强度等级高，则确定第一组音效强度调节值较弱且n的数值较大，例如，可确定第一组音效强度调节值为0、n为20等；若音频数据输出效果的强度等级低，则可确定第一组音效强度调节值较强且n的数值较小，例如第一组音效强度为待添加音效的音效强度值的20％且n＝5，则可尽快平滑的完成音效添加。当获取到需要添加音效的音频数据时，可将n组确定的音效强度调节值依次独立的添加至音频数据上，其中，可预设添加周期，该预设添加周期可根据音频数据的输出时长或者其他因素确定。每个添加周期添加一组音效强度调节值，并且当添加完该组音效强度调节值后，在下一添加周期未到期的时长内，保持该组音效强度调节值，当添加周期到期时，即清除该组音效强度调节值，在音频数据上添加下一组音效强度调节值，即每次添加的音效强度调节值都是单独生效的。即实现了逐步平缓的增加音效强度，避免在添加音效时产生的音效噪音。
可选的，步骤S102的具体实施方式还可为将待添加音效的音效强度值分为上述n组音效强度调节值，该n组音效强度调节值的总和为该待添加音效的音效强度值，并将该n组音效强度调节值依次叠加至该音频数据上。该实施方式的具体实现方法可参见图2～图4所示实施例。
本发明实施例中，通过获取需要添加音效的音频数据，并将n组音效强度调节值依次添加至所述音频数据上，使得音频数据的音效逐渐增强至待添加音效的音效强度值。能够实现平缓的添加音效的音效强度，从而避免在添加音效时产生的音效噪音，提升了用户体验。
请参阅图2，图2是本发明实施例公开的一种音效添加方法的流程示意图。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，获取需要添加音效的音频数据。
在一个实施例中，首先获取需要添加音效的音频数据。其中，该音频数据可从音频文件中获取，也可从视频文件中获取。本发明实施例不做限定。其中，该获取的音频数据为需要添加音效的音频数据，该音频数据可为音频文件或视 频文件中的整体文件数据，也可为其中部分音频数据，即对原始的音频数据进行截取等操作，以获取需要添加音效的音频数据。其中，该音频数据的时长可大于或等于待添加音效的添加时长。
步骤S202，将待添加音效的音效强度值分为n组音效强度调节值，所述n组音效强度调节值的总和为所述音效强度值，n为整数。
在一个实施例中，当获取到需要添加音效的音频数据后，可将待添加音效的音效强度值分为n组音效强度调节值，其中，n组音效强度调节值的总和为该音效强度值。具体的，待添加音效中可包括至少一个音效参数，并且每个音效参数对应一个音效强度值。当待添加音效中包括多个音效参数时，将待添加音效中的每个音效参数对应的音效强度值分为n组音效强度调节值。将每个音效参数对应的音效强度值分为n组音效强度调节值的方式可相同，也可根据具体的音效参数确定不同的划分方式。如某些音效参数基于对音频数据输出噪音的影响不同，其划分为n组音效强度调节值的方式也不同。
当然，同一音效参数对应的音效强度值基于应用场景的不同，也可确定相同或不同的分为n组音效强度调节值的方式。如将音效强度值均等值划分为n组音效强度调节值，即音效强度值＝n*音效强度调节值；又如将音效强度值划分为n组不同的音效强度调节值，该n组不同的音效强度调节值可逐组增加，也可逐组减小。当然，该n组不同的音效强度值还可根据其他的参数确定不同的变化趋势，在此本发明实施例不做限定。
步骤S203，将所述n组音效强度调节值依次叠加至所述音频数据上。
在一个实施例中，当将待添加音效的音效强度分为n组音效强度调节值后，可将该n组音效强度调节值依次添加至上述获取的音频数据上，且在后添加的音效强度与之前添加的所有音效强度叠加生效，即添加的音效强度调节值是叠加生效的。具体的，由于该n组音效强度调节值均小于整体的音效强度值，从而，将该n组音效强度调节值依次添加至音频数据上可避免整体音效强度值增加至音频数据上导致的音频输出噪音。能够将音效平滑的添加至音频数据上。其中，该n组音效强度调节值可按照调节值由大到小或由小到大的顺序添加至音频数据上，当然，该n组音效强度调节值也可根据其他参数依次添加至音频数据上，如根据音频数据的音频强度或者音频数据的音频类型等，当某一时刻音频数据的音频强度高，则该时刻对应的一组音效强度调节值可设置相对较小，以避免产生噪音，或者在音频输出强度允许的范围内，设置该时刻对应的一组音效强度调节值相对较大，以辅助增强该时刻高音频强度的音频数据。当然，上述判断设置音效强度调节值为较大或为较小，还可结合音频类型，若音频类型为平缓类型，如音频数据为轻音乐等，则可设置该组音效强度调节值为较小，以更平缓的方式添加音效；若音频类型为强烈类型，如音频数据为摇滚乐等，则可设置该组音效强度调节值为较大，以在音频输出强度允许的范围内，突出音频数据的输出效果。当然，n组音效强度调节值还可以其他方式依次添加至音频数据上，在此本发明实施例不做限定。
需要说明的是，本发明实施例仅提供了一种步骤S201与步骤S202的执行顺序；当然，步骤S201与步骤S202的执行顺序并不仅限于本发明实施例所述的一种情况，步骤S201可在步骤S202执行后执行，步骤S201与步骤S202也可并列执行，在此，本发明实施例不做限定。
本发明实施例中，通过获取需要添加音效的音频数据，并将n组音效强度调节值依次添加至所述音频数据上，且每次添加的音效强度调节值与之前添加的音效强度调节值叠加，使得音频数据的音效逐渐增强至待添加音效的音效强度值。能够实现平缓的添加音效的音效强度，从而避免在添加音效时产生的音效噪音，提升了用户体验。
请参阅图3，图3是本发明实施例公开的另一种音效添加方法的流程示意图。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，获取需要添加音效的音频数据。
在一个实施例中，首先获取需要添加音效的音频数据。其中，该音频数据可从音频文件中获取，也可从视频文件中获取。本发明实施例不做限定。其中，该获取的音频数据为需要添加音效的音频数据，该音频数据可为音频文件或视频文件中的整体文件数据，也可为其中部分音频数据，即对原始的音频数据进行截取等操作，以获取需要添加音效的音频数据。其中，该音频数据的时长可大于或等于待添加音效的添加时长。
步骤S302，将待添加的音效强度值分为n组相同的音效强度调节值；或者，将所述待添加的音效强度值分为n组逐组递增的音效强度调节值；或者，将所述待添加的音效强度值分为n组逐组递减的音效强度调节值，所述n为正整数。
在一个实施例中，可将待添加的音效强度值分为n组等值的音效强度调节值；或者，将待添加的音效强度值分为n组逐组递增的音效强度调节值；或者，将待添加的音效强度值分为n组逐组递减的音效强度调节值。其中，上述几种划分待添加的音效强度值的方法中，n组音效强度调节值的总和为待添加音效强度值。
具体的，n的数量确定可基于待添加音效的添加时长，若待添加音效的添加时长较长，则确定n取值较大，以实现更加平滑的添加音效强度，若待添加音效的添加时长较短，则确定n取值较小。其中，可将待添加的音效强度值分为n组等值的音效强度调节值，即在每个添加时刻或添加步长时，向音频数据添加的音效强度相同，从而保证平缓的添加音效，可避免音效添加的过程中产生噪音。或者，可将待添加的音效强度值分为n组逐组递增或者n组逐组递减的音效强度调节值。可选的，n组逐组递增或逐组递减的音效强度调节值可为等差数列，即第i+1组与第i组的音效强度调节值的差值相同，该差值可为正值，即形成n组逐组递增的音效强度调节值，该差值也可为负值，即形成n组逐组递减的音效强度调节值。其中，可根据不同的应用场景确定不同的划分方式，若在添加音效的添加时长内音频数据的音频强度逐渐变弱，则音效强度值可划分 为n组逐组递增的音效强度调节值，若一年数据的音频强度逐渐变强，则音效轻度至可划分为n组逐渐递减的音效强度值，以避免音效添加期间产生的音效噪音。
步骤S303，将所述n组音效强度调节值依次叠加至所述音频数据上。
在一个实施例中，将根据上述方式分出的n组音效强度调节值依次叠加至音频数据上。具体的，若将待添加的音效强度分为n组逐组递增的音效强度调节值，则该n组音效强度调节值以递增的方式叠加至音频数据上；若将待添加的音效强度分为n组逐组递减的音效强度调节值，则该n组音效强度调节值以递减的方式依次叠加至音频数据上。若在添加音效的添加时间段内预设了添加步长，则在每个添加步长对应时刻上叠加一组音效强度调节值。
本发明实施例中，通过获取需要添加音效的音频数据，并将n组音效强度调节值依次添加至所述音频数据上，使得音频数据的音效逐渐增强至待添加音效的音效强度值。能够实现平缓的添加音效的音效强度，从而避免在添加音效时产生的音效噪音，提升了用户体验。
请参阅图4，图4是本发明实施例公开的又一种音效添加方法的流程示意图。该方法可由装置实施例中描述的用户终端实现。如图4所示，该方法可包括以下步骤。
步骤S401，获取需要添加音效的音频数据。
在一个实施例中，首先获取需要添加音效的音频数据。其中，该音频数据可从音频文件中获取，也可从视频文件中获取。本发明实施例不做限定。其中，该获取的音频数据为需要添加音效的音频数据，该音频数据可为音频文件或视频文件中的整体文件数据，也可为其中部分音频数据，即对原始的音频数据进行截取等操作，以获取需要添加音效的音频数据。其中，该音频数据的时长可大于或等于待添加音效的添加时长。
步骤S402，确定所述音频数据的音频强度值。
在一个实施例中，当获取到对应的音频数据后，还可确定该段音频数据的音频强度值，其中，该段音频强度值为音频数据的初始强度值，即未调节前的音频强度值，当叠加音效强度后，会得到调节后的音频强度值。
步骤S403，在所述待添加音效的添加时间段内，按照预设的添加步长采集n组音频强度值。
在一个实施例中，根据确定的音频数据的音频强度值，将待添加音效的音效强度值分为与其对应的n组音效强度调节值。上述方式可通过步骤S303～步骤S305实现。具体的，在待添加音效的添加时间段内，按照预设的添加步长采集n组音频强度值，即预设的添加步长确定了添加音效的时间点，通过采集n组音频强度值，可确定该n组音频强度值对应的音效强度调节值。如一组音频强度值高，则为了避免添加产生噪音，确定该组音频强度值对应的音效强度调节值较小，或者，在产生噪音的阈值范围内，确定该组音频强度调节值较大，以增强音频输出效果。
步骤S404，确定所述音频数据的音频类型。
在一个实施例中，还可确定音频数据的音频类型，该音频类型可分为平缓类型、强烈类型等，用以表示音频数据的输出效果。需要说明的是，该音频数据的音频类型为获取的该段音频数据的音频类型，并不一定代表整段音频文件的音频类型。可通过整体判断该段音频数据的音频强度，以确定该段音频数据的音频类型。若整体音频强度强，则音频类型为强烈类型，若整体音频强度弱，则音频类型为平缓类型。
步骤S405,根据所述音频类型确定所述n组音频强度值对应的n组音效强度调节值。
在一个实施例中，可根据确定的音频数据的音频类型，确定n组音频强度值对应的n组音效强度调节值。具体的，若音频数据的音频类型确定出为强烈类型，则音频强度值与音效强度调节值在输出的音频强度不产生噪音的范围内，成正相关关系，即音频强度值越高，则该组对应的音效强度调节值越大；若音频数据的音频类型确定出为平缓类型，则音频强度值与音效强度调节值成负相关关系，即音频强度值越高，则该组对应额音效强度调节值越小。
本发明实施例中，可根据音频数据的音频类型及音频强度确定与其对应的n组音效强度调节值，进而，在避免产生音效噪音的基础上，能够增强该音频数据的输出效果，进一步提升用户体验。
