具体实施方式
以下结合附图与具体实施例进一步阐述本发明的优点。
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
在本公开使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开。在本公开和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
智能终端可以以各种形式来实施。例如，本发明中描述的终端可以包括诸如移动电话、智能电话、笔记本电脑、PDA(个人数字助理)、PAD(平板电脑)、PMP(便携式多媒体播放器)、导航装置等等的智能终端以及诸如数字TV、台式计算机等等的固定终端。下面，假设终端是智能终端。然而，本领域技术人员将理解的是，除了特别用于移动目的的元件之外，根据本发明的实施方式的构造也能够应用于固定类型的终端。
参阅图1，为符合本发明实施例中的一种基于智能终端的音效区分方法的流程示意图。本实施例中，当智能终端中存有多个音效且用户希望识别多个音效中是否存在重复音效或确认智能终端中的多个音效是否均为有效音效时，基于本实施例中的音效区分方法可以帮助用户对智能终端中的音效进行验证。具体地，所述音效区分方法包括如下步骤：
S001：当所述智能终端中包含两个或两个以上的当前音效时，所述智能终端的输出设备采用每一所述当前音效对同一音频进行播放；
在一优选实施例中，所述输出设备包括所述智能终端内置的扬声器、喇叭和/或与所述智能终端相连的外接音频输出装置。
当用户需要对智能终端中的多个音效进行验证时，需要进入智能终端的工程模式，并且在工程模式下打开音频记录器。打开后，将待验证的多个当前音效依次应用于同一音频，音频的音频数据与音效数据叠加，智能终端的音频输出设备依次播放具有任一智能终端内的当前音效的同一音频。其中，本实施例中的音效包括智能终端本体内自带的音效，也包括第三方音效，例如：非流行音效、灵魂音效、说唱音效等。例如，智能终端中存在非流行音效、灵魂音效和说唱音效三种当前音效，为验证该三种音效是否相同。智能终端首先在工程模式下打开音频记录器，然后，智能终端的输出设备包括扬声器、耳机、外接喇叭等，对一音频A分别采用非流行音效、灵魂音效和说唱音效中的任一一个音效依次播放。
在一优选实施例中，本发明所提供的区分音效方法可适用于智能终端内置的音频输出设备，也可以适用于与智能终端外接的音频输出设备。具体包括：内置/外接扬声器、喇叭、音响、MP3播放器等。
S002：记录所述音频基于每一所述当前音效播放时的当前波形；
智能终端的输出设备依次播放多个采用不同音效的同一音频后，进一步通过使用音频记录器记录下采用不同音效的同一音频播放时的波形变化，即为当前波形。其中，当前波形与当前音效是一一对应的。每一个当前波形由播放该音效时，处于每一频点的响 度值连接而成。
S003：比较两个或两个以上的所述当前波形在每一频点的响度值是否均相同；
根据步骤S002，智能终端获得同一音频基于每个音效输出后形成的多个当前波形。进一步将该多个当前波形在每一频点的响度值两两之间进行比较，判断两两当前波形之间在每一频点的响度值是否相同。
S004：当两个或两个以上的所述当前波形在每一所述频点的响度值均相同时，判断所述两个或两个以上的所述当前波形对应的所述当前音效相同；
S004’：当两个或两个以上的所述当前波形在任一所述频点的响度值不同时，判断所述两个或两个以上的所述当前波形对应的所述当前音效不同。
本实施例中，对多个当前音效之间的区分是基于将每一当前音效应用于同一音频上输出，通过比较输出后形成的多个当前波形来实现。对于本实施例中的每一个当前波形而言，其以频段为横轴，以响度值为纵轴。故，本实施例是基于每个当前波形中的每一频点上的响度值作为比较依据来判断与每个当前波形对应的当前音效是否相同。因此，当两个或两个以上的当前波形中的每一个频点的响度值均相同时，所述两个或两个以上的当前波形所对应的多个音效均为相同音效。反之，则为不相同的音效。
在一优选实施例中，当所述当前音效相同时，所述智能终端进一步弹出一提示。
基于本实施例中提供的区分音效方法，当智能终端判断存在两个或两个以上相同的当前音效时，智能终端会进一步弹出一提示窗口，提示包括显示相同的当前音效的名称、位置等相关信息，以提示用户存在相同的当前音效。
参阅图2，为符合本发明实施例中的一种基于智能终端的音效区分方法的流程示意图。本实施例中，当所述智能终端中包含两个或两个以上的当前音效时，所述智能终端的输出设备采用每一所述当前音效对同一音频进行播放的步骤中，所述音效区分方法进一步包括：
解析所述音频的音频数据；
获取每一所述当前音效的音效参数；
依次将每一所述音效参数与所述音频数据叠加，以生成播放数据；
依次根据每一所述播放数据播放采用所述当前音效的所述音频。
本实施例中，当智能终端的输出设备将智能终端内的当前音效一一应用于同一音频中，并播放的步骤中进一步包括：
首先，需要对该智能终端中的音频进行解析，以获得该音频的音频数据。该音频数据为需要添加音效的音频数据。获得原始的音频数据后，对于多个待区分的音效，本实施例中的区分方法可以分别依次获得需要采用的每一当前音效的音效参数，包括对每一频点的音频响度值的变化参数。获得音效参数后，进一步将音效参数与音频数据叠加，以输出一采用一当前音效的音频。基于智能终端中有多个当前音效，因此，本实施例中为区分多个当前音效，该音频需与每一当前音效叠加输出。例如，智能终端中有3个当前音效时，该音频需每次分别与1个当前音效叠加，共需输出三次。
参阅图3，为符合本发明实施例中的一种基于智能终端的音效区分方法的流程示意图。本实施例中，记录所述音频基于每一所述当前音效播放时的当前波形的步骤中，进一步包括：
通过一音频记录器采集基于每一所述当前音效播放的所述音频在每一频点的响度值；
根据所述每一频点的响度值，生成所述当前波形。
本实施例中，进一步说明了当前波形是一基于频点和响度值的二维图形。该图形中的每一个点对应的为每一频点时一输出音频具有的响度值。而本实施例中，具体通过一智能终端中一内置的音频记录器来采集每个输出音频在每一个频点的响度值。对每一个 频点的响度值采集完成后，进一步根据采集所得的数据生成该输出音频的当前波形。
参阅图4，为符合本发明实施例中的一种基于智能终端的音效区分***的结构示意图。本实施例中，当智能终端中存有多个音效且用户希望识别多个音效中是否存在重复音效或确认智能终端中的多个音效是否均为有效音效时，基于本实施例中的音效区分***可以帮助用户对智能终端中的音效进行验证。具体地，所述音效区分***包括：输出模块、记录模块、对比模块、判断模块；
所述输出模块，与所述记录模块通讯连接，当所述智能终端中包含两个或两个以上的当前音效时，所述输出模块采用每一所述当前音效对同一音频进行播放；
在一优选实施例中，所述输出模块包括所述智能终端内置的扬声器、喇叭和/或与所述智能终端相连的外接音频输出装置。
当用户需要对智能终端中的多个音效进行验证时，需要进入智能终端的工程模式，并且在工程模式下打开音频记录器。打开后，将待验证的多个当前音效依次应用于同一音频，音频的音频数据与音效数据叠加，输出模块依次播放多个采用任一智能终端内的当前音效的同一音频。其中，本实施例中的音效包括智能终端本体内自带的音效，也包括第三方音效，例如：非流行音效、灵魂音效、说唱音效等。例如，智能终端中存在非流行音效、灵魂音效和说唱音效三种当前音效，为验证该三种音效是否相同。智能终端首先在工程模式下打开音频记录器，然后，输出模块对一音频A分别采用非流行音效、灵魂音效和说唱音效中的任一一个音效依次播放。
在一优选实施例中，本发明所提供的区分音效***可适用于智能终端内置的输出模块，也可以适用于与智能终端外接的输出模块。具体包括：内置/外接扬声器、喇叭、音响、MP3播放器等。
所述记录模块，与所述输出模块、对比模块通讯连接，记录所述音频基于每一所述当前音效播放时的当前波形；输出模块依次播放多个采用不同音效的同一音频后，进一步记录模块中的音频记录器记录下采用不同音效的同一音频播放时的波形变化，即为当前波形。其中，当前波形与当前音效是一一对应的。每一个当前波形由播放该音效时，处于每一频点的响度值连接而成。
所述对比模块，与所述记录模块、判断模块通讯连接，比较两个或两个以上的所述当前波形在同一频点的响度值是否均相同；
基于记录模块，本实施例中的区分音效***获得同一音频基于每个音效输出后形成的多个当前波形。对比模块进一步将该多个当前波形在每一频点的响度值两两之间进行比较，以使判断模块判断两两当前波形之间在每一频点的响度值是否均相同。
当两个或两个以上的所述当前波形在每一所述频点的响度值均相同时，判断模块判断所述两个或两个以上的所述当前波形对应的所述当前音效相同；
当两个或两个以上的所述当前波形在任一所述频点的响度值不同时，判断模块判断所述两个或两个以上的所述当前波形对应的所述当前音效不同。
本实施例中，区分音效***对多个当前音效之间的区分是基于输出模块将每一当前音效应用于同一音频上输出，再由比较模块比较输出后形成的多个当前波形来实现。对于本实施例中的每一个当前波形而言，其以频段为横轴，以响度值为纵轴。故，本实施例中的比较模块是基于每个当前波形中的每一频点上的响度值作为比较依据的，而判断模块基于比较模块的比较结果来判断与每个当前波形对应的当前音效是否相同。因此，当比较模块比较得出两个或两个以上的当前波形中的每一个频点的响度值均相同时，判断模块则判断所述两个或两个以上的当前波形所对应的多个音效均为相同音效。反之，则为不相同的音效。
在一优选实施例中，
所述音效区分***进一步设有一提示模块，所述提示模块与所述判断模块通讯连接；
当所述判断模块判断两个或两个以上的所述当前音效相同时，所述提示模块进一步弹出一提示。
基于本实施例中提供的区分音效***，当判断模块判断存在两个或两个以上相同的当前音效时，进一步通过通讯连接将判断结果发送至提示模块，提示模块会进一步弹出一提示窗口，提示包括显示相同的当前音效的名称、位置等相关信息，以提示用户存在相同的当前音效。
参阅图5，为符合本发明实施例中的一种基于智能终端的音效区分***的结构示意图。本实施例中，所述输出模块进一步包括：
解析单元，解析所述音频的音频数据；
获取单元，获取每一所述当前音效的音效参数；
叠加单元，依次将每一所述音效参数与所述音频数据叠加，以生成播放数据；
播放单元，依次根据每一所述播放数据播放采用所述当前音效的所述音频。
本实施例中，当输出模块将智能终端内的当前音效一一应用于同一音频中，并播放的步骤中进一步包括：
首先，输出模块中的解析单元需要对该智能终端中的音频进行解析，以获得该音频的音频数据。该音频数据为需要添加音效的音频数据。解析单元获得原始的音频数据后，对于多个待区分的音效，进一步地，获取单元可以分别依次获得需要采用的每一当前音效的音效参数，包括对每一频点的音频响度值的变化参数。获取单元获得音效参数后，叠加单元进一步将音效参数与音频数据叠加，最后由播放单元输出一采用一当前音效的所述音频。基于智能终端中有多个当前音效，因此，本实施例中为区分多个当前音效，播放单元输出的音频需通过叠加单元与每一当前音效叠加后方可输出。例如，智能终端中有3个当前音效时，播放单元输出该音频时，叠加单元需每次分别将该音频与1个当前音效叠加，故，播放单元共需输出三次。
参阅图6，为符合本发明实施例中的一种基于智能终端的音效区分***的结构示意图。本实施例中，所述记录模块进一步包括：
采集单元，通过一音频记录器采集基于每一所述当前音效播放的所述音频在每一频点的响度值；
生成单元，根据所述每一频点的响度值，生成所述当前波形。
本实施例中，进一步说明了当前波形是一基于频点和响度值的二维图形。该图形中的每一个点对应的为每一频点时一输出音频具有的响度值。而本实施例中，具体通过记录模块的采集单元中的音频记录器来采集每个输出音频在每一个频点的响度值。采集单元对每一个频点的响度值采集完成后，进一步生成单元根据采集所得的数据生成该输出音频的当前波形。
相比于现有技术，本发明提供的技术方案基于不同音效之间的波形在每一频点的响度变化对多个不同或相近的音效之间加以区分，相比于主观判断，更为合理，精确度更高。
应当注意的是，本发明的实施例有较佳的实施性，且并非对本发明作任何形式的限制，任何熟悉该领域的技术人员可能利用上述揭示的技术内容变更或修饰为等同的有效实施例，但凡未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何修改或等同变化及修饰，均仍属于本发明技术方案的范围内。
