目前录音的保存方式比较单一，普遍采用的方法都是将录音保存为音频文件，再在录音文件的文件名上对文件进行一定的区分。或是用文件名记录通话时间，或是用文件名记录通话号码。采用此种方式保存通话录音，记录的信息往往过于简单，展示起来过于单薄。由于文件名的长度等限制，无法深度保存通话录音信息，而且保密性也不好。在通话时间较久的情况下，经常无法回忆起此通话录音的具体场景。例如，目前双卡移动终端非常普及，用户使用多张卡在移动终端中切换的现象也很常见。移动终端的通话录音现今采用的技术方案无法展示多种的通话信息。

下文中将结合附图对本发明的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
实施例一
本实施例将通话录音的多种信息保存在显示内容中，来实现对通话录音的扩展。文中，录音的多种信息指除音频数据外与录音相关的多种信息，所属录音包括通话录音，通话录音的多种信息包括：通话时间、通话号码、通话时长、通话位置、通话内容等。
本实施例保存通话录音的方法应用于终端，如图1所示，包括：
步骤110，在通话录音过程中，记录所述通话录音的音频数据和多种信息；
本实施例以移动终端为例。在移动终端进行通话时，用户手动选择或自动开始通话录音，在通话录音过程中，移动终端实时记录通话录音的音频数据，如保存在缓存中。记录的音频数据可以是PCM(脉冲编码调制：Pulse Code Modulation)音频数据，但本发明并不局限于此。
在通话录音进行时及结束时，移动终端可以获取通话录音的多种信息。所述多种信息如可以包括以下信息中的至少二种：通话开始时间、通话结束时间、主叫号码、被叫号码、通话时长、主叫位置、被叫位置、主叫联系人、被叫联系人，及经语音识别得到的全部或部分通话内容。
步骤120，将所述音频数据和多种信息保存到文件中，其中，将所述多种信息保存到所述文件的显示内容中。
本实施例中，可以将所述音频数据和多种信息保存到同一文件中。
但在另一实施例中，将所述音频数据和多种信息保存到多个文件中。为了将所述音频数据和多种信息相关联，所述多个文件的文件名至少部分相同。音频数据和多种信息保存到多个文件的方式，包括：多种信息保存到图片文件的显示内容中，而音频数据用音频文件保存；或者，多个文件中的每一文件分别保存所述录音的一部分数据，且多个文件均保存有所述录音的多种信息。
上述保存音频数据和多种信息的文件可以是具有显示内容并可以保存音频数据的文件，在后续的实施例二和实施例三中，分别以图片文件和视频文件为例进行说明。
在图片的显示内容中，多种信息通常可以显示为文本的形式，但也可以显示为其他形式，如通话时间也可以显示为相应的时钟图案，通话地点也可以显示为相应的地图，等等。
可以在通话录音结束后，生成一文件，将缓存的音频数据和多种信息保存在该文件中，也可以在通话录音开始后即生成一临时的文件，将采集的音频数据和多种信息保存在该文件中，通话录音结束后再生成正式文件。
本发明实施例还提供了一种计算机存储介质，所述计算机存储介质中存储有计算机可执行指令，所述计算机可执行指令用于执行上述的方法。
本实施例还提供了一种可保存通话录音的终端，可以是手机等移动终端但不局限于此。如图2所示，该终端包括：
通话录音模块10，设置为在通话录音过程中，记录所述通话录音的音频数据和多种信息；
录音保存模块20，设置为将所述音频数据和多种信息保存到文件中，其中，将所述多种信息保存到所述文件的显示内容中。
可选地，
所述通话录音的多种信息包括以下信息中的至少二种：通话开始时间、通话结束时间、主叫号码、被叫号码、通话时长、主叫位置、被叫位置、主叫联系人、被叫联系人，及经语音识别得到的全部或部分通话内容。
通过将通话录音的多种信息保存在文件的显示内容中，避免了相关技术在文件名中保存通话录音信息时受到的局限，显示内容(如图片显示内容、视频显示内容)本身可以记录很多通话时的相关信息，丰富了通话录音的内容。有利于帮助用户回忆起此通话录音的具体场景，从而改善用户体验。
实施例二
本实施例将通话录音的多种信息保存在同一图片文件中。
本实施例保存通话录音的方法如图3所示，包括：
步骤210，在通话录音过程中，记录所述通话录音的音频数据和多种信息；
本步骤同步骤110。
步骤220，将所述多种信息保存到所述图片文件的显示内容中，将所述音频数据填充到所述图片文件的指定保留段中。
本步骤中，如果指定保留段专用于保存所述音频数据，则根据所述指定保留段是否为空即可判断是否存在音频数据。如果非专用于音频数据，则需要在指定保留段的指定位置添加录音标识符，所述录音标识符用于标识本图片文件为保存通话录音的图片文件。所述指定位置可以是指定保留段数据的首位置和/或尾位置。
将所述音频数据填充到所述图片文件的指定保留段中时，比较音频数据和指定保留段的大小，如果音频数据可以填充到一个指定保留段中，则直接将所述音频数据填充到图片文件的一个指定保留段中；如果音频数据大于指定保留段的大小，需要将所述音频数据分片后，分别填充到图片文件的多个指定保留段中。
在一个示例中，图片文件采用联合图片专家小组(JPEG：Joint Photographic Experts Group)制定的图片格式如JPEG，JPEG2000等格式。所述指定保留段包括一个或多个APP15段，也即将通话录音的音频数据填充到JPEG图片的APP15段。但要说明的是，对于图片格式本发明并不限制，也可以采用其他格式。图片的显示内容可以是静态，也可以是动态的。
通话录音保存完毕后，需要向用户展示所述多种信息并实现对音频数据的播放。本实施例生成的图片文件在打开后还需要对其中的音频数据做提取和播放的处理，这将在实施例四说明。
在另一实施例中，可以将通话录音保存在特定的图片文件中(非通用格式)，使用特定的应用来打开。此时，可以另行定义该图片文件保存音频数据的位置，不需要保存在保留段中。
本发明实施例还提供了一种计算机存储介质，所述计算机存储介质中存储有计算机可执行指令，所述计算机可执行指令用于执行上述的方法。
本实施例还提供一种可保存通话录音的终端，包括：
通话录音模块，设置为在通话录音过程中，记录所述通话录音的音频数据和多种信息；
录音保存模块，设置为将所述多种信息保存到所述图片文件的显示内容中，将所述音频数据填充到所述图片文件的指定保留段中。
可选地，
所述录音保存模块将所述音频数据和多种信息保存到一文件中，还包括：在所述指定保留段的指定位置添加录音标识符，所述录音标识符用于标识本图片文件为保存通话录音的图片文件。
可选地，
所述录音保存模块将所述音频数据填充到所述图片文件的指定保留段中，包括：将所述音频数据填充到所述图片文件的一个指定保留段中；或者，将所述音频数据分片后，分别填充到所述图片文件的多个指定保留段中。
可选地，
所述图片文件采用联合图片专家小组JPEG制定的图片格式，所述指定保留段包括一个或多个APP15段。
可选地，
所述通话录音的多种信息包括以下信息中的至少二种：通话开始时间、通话结束时间、主叫号码、被叫号码、通话时长、主叫位置、被叫位置、主叫联系人、被叫联系人，及经语音识别得到的全部或部分通话内容。
本实施例将通话录音的多种信息保存在图片文件的显示内容中，可以直观地以图片的形式展现通话时间、通话地点、主被叫号码和通话时长等信息。从而帮助用户回忆起此通话录音的具体场景，改善了用户体验
由于本实施例的图片文件与普通的图片文件不同，即使拷贝到别的手机
上也不能正常播放。不熟悉采用本方案手机的可能仅仅以为某通话录音是一张图片而已，这在一定程度上进行了浅度的加密。
实施例三
本实施例将通话录音的多种信息保存在同一视频文件中。
本实施例保存通话录音的方法如图4所示，包括：
步骤310，在通话录音过程中，记录所述通话录音的音频数据和多种信息；
本步骤同步骤110。
步骤320，将所述多种信息保存到一帧或多帧图像的显示内容中，再将所述一帧或多帧图像与所述音频数据拼接，生成所述视频文件。
本步骤生成的视频文件的音频数据即为通话录音的音频数据，图像数据包含通话录音的通话时间、通话号码、通话时长、通话位置等多种信息。这样既扩展了通话录音，又保留了通话录音的通用性。本实施例生成的视频文件是普通的视频文件，即使更换了移动终端，依然可以正常播放。
根据本实施例的方法，用户打开保存通话录音的音频文件时，将播放包含通话时间、主被叫号码和通话时长等信息的图像帧，同时播放通话录音的音频内容。
本发明实施例还提供了一种计算机存储介质，所述计算机存储介质中存储有计算机可执行指令，所述计算机可执行指令用于执行上述的方法。
本实施例还提供一种可保存通话录音的终端，包括：
通话录音模块，设置为在通话录音过程中，记录所述通话录音的音频数据和多种信息；
录音保存模块，将所述多种信息保存到一帧或多帧图像的显示内容中，再将所述一帧或多帧图像与所述音频数据拼接，生成所述视频文件。
可选地，
所述通话录音的多种信息包括以下信息中的至少二种：通话开始时间、通话结束时间、主叫号码、被叫号码、通话时长、主叫位置、被叫位置、主叫联系人、被叫联系人，及经语音识别得到的全部或部分通话内容。
实施例四
本实施例提供一种显示和播放图片形式通话录音的方法，可以对实施例二保存通话录音的图片文件进行显示和播放。
本实施例方法的流程如图5所示，包括：
步骤410，接收到打开图片文件的指令后，解析所述图片文件的内容；
步骤420，确定所述图片文件是否保存通话录音的图片文件，如是，执行步骤440，如否，执行步骤430；
本实施例中，通过以下方式确定所述图片文件是否保存通话录音的图片文件：解析所述图片文件的指定保留段，如所述指定保留段的指定位置有录音标识符，则确定所述图片文件是保存通话录音的图片文件；如所述指定保留段的指定位置没有录音标识符，确定所述图片文件不是保存通话录音的图片文件。
步骤430，显示图片的内容，结束；
步骤440，显示所述图片文件的显示内容，并从所述图片文件的其他内容中提取所述通话录音的音频数据进行播放；其中，所述显示内容包含所述通话录音的多种信息。
本实施例中，是从所述指定保留段中提取所述通话录音的音频数据进行播放。如有一个所述指定保留段的指定位置有录音标识符，从该指定保留段中提取所述通话录音的音频数据并进行播放；如有多个所述指定保留段的指定位置有录音标识符，从该多个指定保留段中分别提取所述音频数据，拼接为一整段数据后进行播放。
在一示例中，所述图片文件采用联合图片专家小组JPEG制定的图片格式，所述指定保留段包括一个或多个APP15段。
可选的，本实施例的上述方法中，以下一种或多种处理是所述终端操作
系统框架层的图片解析库执行的：
解析所述图片文件的指定保留段，如所述指定保留段的指定位置有录音标识符，则确定所述图片文件是保存通话录音的图片文件；
从所述指定保留段中提取所述通话录音的音频数据进行播放；其中，对音频数据进行播放是将音频数据传送给音频播放器进行播放。
通过系统框架层的图片解析库执行上述操作，就可以使用常用的图片应用来打开保存通话录音的图片文件并实现对音频的播放。但本发明不局限于此，在另一实施方式中，上述处理也可以由应用执行，也即提供一个特定的应用，该应用可以实现对保存通话录音的图片文件的图片显示和音频播放，此时无需对操作系统框架层的图片解析库进行改动。
所述通话录音的多种信息包括以下信息中的至少二种：通话开始时间、通话结束时间、主叫号码、被叫号码、通话时长、主叫位置、被叫位置、主叫联系人、被叫联系人，及经语音识别得到的全部或部分通话内容。
根据本实施例的方法，用户打开保存通话录音的图片文件时，将以图片的形式展现通话时间、主被叫号码和通话时长等信息，通话录音的内容则以音频的形式播放。
在另一实施例中，是使用特定的图片文件作为保存通话录音的图片文件。此时，可以通过解析图片文件格式本身而获知该图片文件是保存通话录音的图片文件，而该图片文件中音频数据的保存位置可在文件格式中约定，不一定要保存在保留段中。
本发明实施例还提供了一种计算机存储介质，所述计算机存储介质中存储有计算机可执行指令，所述计算机可执行指令用于执行上述的方法。
本实施例还提供了一种可播放图片形式通话录音的终端，如图6所示，包括：
图片解析模块50，设置为在接收到打开图片文件的指令后，解析所述图片文件的内容；
图片显示和播放模块60，设置为在所述图片解析模块确定所述图片文件
是保存通话录音的图片文件时，显示所述图片文件的显示内容，并从所述图片文件的其他内容中提取所述通话录音的音频数据进行播放；其中，所述显示内容包含所述通话录音的多种信息。
可选地，
所述图片解析模块解析所述图片文件的内容，包括：解析所述图片文件的指定保留段，如所述指定保留段的指定位置有录音标识符，则确定所述图片文件是保存通话录音的图片文件；
所述图片显示和播放模块从所述图片文件的其他内容中提取所述通话录音的音频数据进行播放，包括：从所述指定保留段中提取所述通话录音的音频数据进行播放。
可选地，
所述图片显示和播放模块从所述指定保留段中提取所述通话录音的音频数据进行播放，包括：
如有一个所述指定保留段的指定位置有录音标识符，从该指定保留段中提取所述通话录音的音频数据并进行播放；
如有多个所述指定保留段的指定位置有录音标识符，从该多个指定保留段中分别提取所述音频数据，拼接为一整段数据后进行播放。
可选地，
所述图片文件采用联合图片专家小组JPEG制定的图片格式，所述保留段包括APP15段。
可选地，
所述图片解析模块通过操作系统框架层的图片解析库或应用执行以下处理：解析所述图片文件的指定保留段，如所述指定保留段的指定位置有录音标识符，则确定所述图片文件是保存通话录音的图片文件；和/或
所述图片显示和播放模块通过操作系统框架层的图片解析库或应用完成以下处理：从所述指定保留段中提取所述通话录音的音频数据进行播放；其中，对音频数据进行播放是将音频数据传送给音频播放器进行播放。
可选地，
所述通话录音的多种信息包括以下信息中的至少二种：通话开始时间、通话结束时间、主叫号码、被叫号码、通话时长、主叫位置、被叫位置、主叫联系人、被叫联系人，及经语音识别得到的全部或部分通话内容。
虽然上述实施例均以通话录音为例，但本发明并不局限于通话录音，对于其他录音，也可以用上述实施例的方法来保存和打开，也可以记录很多说话时(不一定是用户通过终端之间的通话)的相关信息，丰富录音的内容。帮助用户回忆起此录音的具体场景。
下面再用几个具体应用中的示例进行说明。
示例一
本示例将通话录音保存为JEPG图片格式，包括：
步骤一、用户在通话时，选择录音，此时移动终端记录开始通话录音时间及通话录音的PCM音频数据；
步骤二、通话结束时，生成一JPEG图片文件，将通话时间、主被叫号码和通话时长等录音通话的多种信息保存在图片的显示内容中；
例如，在android系统上，可以调用Canvas类将通话时间、主被叫号码和通话时长等信息保存在JPEG图片的显示内容中；在IOS系统上，则可以调用Core Graphics将这些信息保存在JPEG图片的显示内容中。
步骤三、在生成的JPEG图片文件的APP15段，填充PCM音频数据。
JPEG定义的部分标记(Marker)见表1：
表1
JPEG标准保留段很多，以上只列出几种。其中的APP 0-15段是JPEG标准预留给应用程序自己使用的标记，比较适合于填充音频数据。
JPEG APP1-15分区的定义见表2：
表2
可以看到，分区数据段最大不超过64k字节，在录音数据超过64k字节大小时，可以采用定义多个APP15段，将音频数据分片后，分别保存在该多个APP15段。可选地，在JPEG图片文件生成完毕后，可以设置一个阀值，
该阀值小于APP15分区的最大宽度64k字节。将通话录音的PCM音频数据的大小与该阀值进行比较，若不超过该阈值，则将此PCM录音数据存储到JPEG图片文件的一个APP15段中；若超过该阈值，则将此PCM音频数据按顺序分片，每个分片的大小均小于等于该阈值，分片后，将每一分片数据依次保存到一个APP15段中。
在每一个APP15段中，用设定的录音标识符标记PCM音频数据。该录音标识符可以为一段特定的字符串：＝_Record_B38787EHK79EH67IKJ，该录音标识符在APP15分区的“详细信息”的首、尾均出现，PCM音频数据填充在该两个录音标识符之间，如图7所示。用于标志PCM音频数据的录音标识符可以将音频数据与其他数据区分开来。
示例二
本示例提供一种显示和播放图片形式通话录音的方法，包括：
步骤一、在终端上打开JPEG图片文件，查找该JPEG图片文件中APP15段是否存在录音标识符，以确定该JPEG图片文件是否为保存通话录音的JPEG图片文件；
本示例中，如果在APP15分区的“详细信息”部分的头和尾都存在录音标识符，则此图片为通话录音。在android系统上，可以在操作系统框架层的JPEG图片解析库中加入对APP15分区的特殊处理，读到APP15段的分区标记即在其中查找录音标识符，如果在APP15分区“详细信息”部分的头和尾均找到录音标识符，则可以确定该JPEG图片文件是保存通话录音的JPEG图片文件。操作系统框架层的JPEG图片解析库可以通知上层应用，该JPEG图片文件是保存通话录音的JPEG图片文件。
如果不是通话录音，则正常打开JPEG图片文件，显示图片。
步骤二、如果存在录音标识符，说明该JPEG图片文件是保存通话录音的JPEG图片文件，首先正常显示图片的显示内容(这里包含了通话时间、主被叫号码和通话时长等多种信息)，同时提取隐藏在APP15段中的录音数据，以音频的形式播放给用户。
提取隐藏在APP15段中的录音数据时，需查找APP15的段数，如果有多段，需逐段提取PCM音频数据，并将PCM音频数据拼接为一整段数据后播放。在android系统上，可以在操作系统框架层的JPEG解析逻辑中完成拼接的工作。在解析完毕后，将PCM音频数据流传送给mediaplayer进行播放。在框架层中完成这些动作，可以减少上层应用的工作。
应当说明的是，上述对APP15段的特殊处理也可以在上层应用中完成。
示例三
本示例将通话录音保存为视频文件。该方法包括：
步骤一、用户在通话时，选择录音，此时移动终端记录开始通话录音时间并开始记录通话录音的PCM音频数据；
步骤二、通话结束时，生成一帧图像，将通话时间、通话号码、通话时长、通话位置等信息保存到该帧图像中；
在另一示例中，也可以生成多帧图像来保存这些信息。
步骤三、将步骤二生成的该帧图像和通话录音的PCM音频数据进行拼接，生成一视频文件。
在一个示例中，拼接为MPEG4视频文件，将生成的该帧图像作为第一帧，将PCM音频数据作为音轨，按照PCM数据的时间长度生成同样长度的视频，在时间维度上，逐帧插值。
本示例将通话录音的音频数据作为生成的视频文件的音频内容，视频内容则用通话时间、主被叫号码和通话时长等信息构建的图像帧填充；完成两者的拼接之后，在播放此视频的时候，除了正常的播放通话录音的音频内容，还可以直观显示通话时间、主被叫号码和通话时长等多种信息。
本领域普通技术人员可以理解上述方法中的全部或部分步骤可通过程序来指令相关硬件(例如处理器)完成，所述程序可以存储于计算机可读存储
介质中，如只读存储器、磁盘或光盘等。可选地，上述实施例的全部或部分步骤也可以使用一个或多个集成电路来实现。相应地，上述实施例中的各模块/单元可以采用硬件的形式实现，例如通过集成电路来实现其相应功能，也可以采用软件功能模块的形式实现，例如通过处理器执行存储于存储器中的程序/指令来实现其相应功能。本发明不限制于任何特定形式的硬件和软件的结合。
本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的精神和范围，均应涵盖在本发明的权利要求范围当中。
上述技术方案避免了相关技术在文件名中保存通话录音信息时受到的局限，显示内容(如图片显示内容、视频显示内容)本身可以记录很多通话时的相关信息，丰富了通话录音的内容。有利于帮助用户回忆起此通话录音的具体场景，从而改善用户体验。
