具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例提供了一种音频文件传输方法、装置和音频接收方法和装置，上述方法和装置可以实现将个人PC机、移动电话等用户终端设备中的音频文件提供给蓝牙耳机、蓝牙音箱等蓝牙设备，并在蓝牙设备端实现音频文件的存储，以下举例说明上述方法和装置的应用环境。
图1是本发明实施例提供的音频文件处理系统的应用环境的示意图；其中， 图1(a)、图1(b)和图1(c)示出了三种通过用户终端设备20向蓝牙设备10提供音频文件的应用场景，其中，所述应用场景还可以包括用户(图中未示出)，所述用户可以通过任何合适的类型的、一种或者多种用户交互设备与用户终端设备20和蓝牙设备10交互，例如，这些用户交互设备可以是鼠标、按键、遥控器、触摸屏、体感摄像头或者智能可穿戴设备，通过输入指令控制用户终端设备20和蓝牙设备10进行一种或者多种操作，如音频播放操作。
所述用户终端设备可以是任何合适的，提供一个或者多个音频内容的各类型用户终端设备，例如，智能手机、平板电脑、MP3播放器、个人电脑、手提电脑、个人音响、CD机或者其它智能/非智能终端设备。用户终端设备耦合至至少一个用于存储音频数据的存储介质中，这些存储介质可以是用户终端设备内的存储器，也可以是互联网上的存储介质，并从存储介质中获取音频文件。此外，该用户终端设备还可以是一种或者多种电子设备的组合，例如，智能手机以及与其连接的模数转换器(DAC)。
蓝牙设备可以是任何合适的，具有播放音频数据能力及存储能力的设备，例如，蓝牙耳机、蓝牙音箱或者其它合适类型的扬声器组。图1(a)示出了通过个人PC机向蓝牙音箱提供音频数据的场景。所述图1(b)示出了通过个人PC机向蓝牙扬声器提供音频数据的场景，图1(c)示出了通过移动电话向蓝牙耳机提供音频数据的场景。
其中，用户终端设备可以通过内部集成或者外部的蓝牙模块或者蓝牙芯片实现与蓝牙设备的连接。当两台具有蓝牙功能的设备建立连接时，它们会获取对应设备提供的协议。只有使用相同协议的设备才能交换数据。
在蓝牙通信中，具有蓝牙功能的设备不需要实现全部的蓝牙规范。为了支持不同的蓝牙设备之间的兼容，在蓝牙规范中定义了一些应用层协议(profile)，其用以定义具有蓝牙功能的设备之间如何实现一种连接或者应用。
其中，A2DP(Advenced Audio Distribution Profile高级蓝牙音频传输模型协议)属于上述的蓝牙协议profile中的一个子集。用于传输高质量音乐文件数据的协议堆栈和使用方法，A2DP是专门为使用蓝牙传送立体声音频而制定。
HFP(Hands Free Profile)，HFP只能传输单声道加密音频，相比于A2DP，传输质量要差得多。A2DP能传输(16bits，44.1kHz)的音频，而HFP只能传输(8bits，8kHz)的音频，HFP可用于传输语音信号。
BLE(Bluetooth low energy)，属于蓝牙低功耗协议，主要用于进行短时间小数据传输。
用户终端设备可以根据用户指令，与蓝牙设备之间建立蓝牙连接，其中，用户终端设备可以通过第一蓝牙音频传输协议(例如A2DP协议或者HFP协议)向蓝牙设备传递音频数据，而通过第二蓝牙传输协议(例如BLE协议)向蓝牙设备传递与音频数据相关的音频信息(例如，音乐的名称、演唱者或者演奏者的姓名、音乐类别以及语音发出者等)。根据所述音频信息在蓝牙设备的存储器中建立音频文件夹，并将所述音频数据存储在所述音频文件夹中，实现音频文件在蓝牙设备的存储。
本发明实施例并不限于以上蓝牙协议，在实际应用中，可以根据需要采用其他合适的蓝牙协议用于传输音频数据和采用其他合适的协议用于传输音频信息。
在集成蓝牙芯片的用户终端设备播放音频文件时，蓝牙芯片可以通过脉冲编码调制(PCM)有线CODEC接口(例如标准硬件立体声PCM接口)接收音频信号(所述音频信号可以为MP3格式或者其他格式)，对所述音频信号进行解码，输出PCM音频裸数据。由于PCM音频裸数据需要很大的带宽，即低效又费电，不适合无线传输，因此需要对PCM音频裸数据进行音频编码对其进行压缩，之后，将压缩的音频数据进行分包，组合成符合蓝牙传输协议的音频数据。在采用A2DP协议的场合，即组合成A2DP音频数据帧，例如frame1、frame2……frameN。蓝牙设备收到传输过来的经过压缩和分包的音频数据后，可以直接将经过压缩和分包的音频数据存储在音频文件夹里，需要播放的时候再进行解码；也可以经过解码处理后，再将音频数据存储在音频文件夹中。
在A2DP协议中，满足A2DP协议的音频编码格式有SBC(Sub Band Coding次频带编码)、AAC(Advanced Audio Coding，高级音频编码)以及Apt-X等格式。其中，SBC编码格式的编码率44.1kHz双声道最大为328kbit/s，AAC编码格式的编码率可达320kbit/s，Apt-X编码格式的编码率可达352kbit/s。
下面结合具体实施例对本发明实施例作进一步阐述。
图2为本发明实施例提供的一种音频文件传输方法流程示意图。本发明实施例的一种音频文件传输方法可由图1所示的各种用户终端设备执行，如图2所示，所述方法包括：
201：以第一蓝牙音频传输协议传输所述音频文件的音频数据至蓝牙设备；
在实际应用中，所述用户终端设备将音频数据通过第一蓝牙音频传输协议，比如A2DP,发送给蓝牙设备的操作可以采用多种方式触发，例如，当用户建立用户终端设备和蓝牙设备之间的连接后，打开用户终端设备的音频播放器，此时，用户终端设备将会把音频数据发送到蓝牙设备。
在本发明实施例中，音频文件的音频数据可以是由用户终端设备，比如，智能手机，将音频文件的MP3格式转化为PCM格式，并将PCM格式编码为SBC、AAC、Apt-X等格式，并将各种格式的音乐分成一帧一帧，比如，frame1、frame2……frameN,然后通过A2DP将各帧音频数据传输至蓝牙设备，比如，蓝牙耳机。
202：以第二蓝牙传输协议传输所述音频文件的音频信息至蓝牙设备。
在本发明实施例中，用户终端设备在发送音频数据的同时，或者前后间隔一段时间将与所述音频数据对应的音频信息发送到蓝牙设备。
在本发明实施例中，用户终端设备可以播放存储在用户终端设备本地的音频文件，并在通过A2DP传输音频文件的音频数据的过程中，以第二蓝牙传输协议传输所述音频文件的音频信息至蓝牙设备，也可以在线播放网络音频文件，并将音频文件中的音频数据与音频信息分别以A2DP及BLE传输至蓝牙设备，其中，第二蓝牙传输协议为BLE,音频信息用于建立音频文件夹，音频信息可以包括歌曲名称、歌手名称和/或歌曲类别，而且，音频信息与音频数据属于同一音频文件。
在本发明实施例中，用户终端设备也可以在线播放网络音频文件，并将音频文件中的音频数据与音频信息分别以A2DP及BLE传输至蓝牙设备。
本发明实施例，通过第一蓝牙音频传输协议传输音频文件的音频数据并通过第二蓝牙传输协议传输音频文件的音频信息至蓝牙设备，以提供音频文件给蓝牙设备，从而丰富音频文件的播放方式，提升用户体验。
图3为本发明实施例提供的另一种音频文件传输方法流程示意图；所述方法亦可由图1所示的各种用户终端设备执行，如图3所示，所述方法包括：
301：以第二蓝牙传输协议传输缓存开始指令至蓝牙设备。
在本发明实施例中，为了提高音频数据在蓝牙设备的存储速度，可以将音频数据先存入缓存，比如，静态随机存取存储器SRAM中，蓝牙设备将音频数据 存入缓存的操作可由用户终端设备端进行控制，用户终端设备在发送音频数据的同时，或者前后间隔一段时间，向蓝牙设备发送缓存开始指令，蓝牙设备接收到音频数据和缓存开始指令后，将所述音频数据存储在缓存中。
302，以第一蓝牙音频传输协议传输所述音频文件的音频数据至蓝牙设备。
在本发明实施例中，可以在以BLE传输缓存开始指令后，以A2DP传输音频数据，在此情况下，蓝牙设备将接收到的音频数据缓存。当然，也可以先以A2DP传输音频数据，然后通过BLE传输缓存开始指令，此时，再将接收的音频数据存储至缓存。
303、以第二蓝牙传输协议传输缓存结束指令至蓝牙设备。
在本发明实施例中，当缓存的音频数据达到预设静态随机存取存储器的存储容量时，或者，音频文件的音频数据传输完成，可以通过BLE传输缓存结束指令至蓝牙设备，蓝牙设备在收到缓存结束指令时终止音频数据在缓存中的存储。
304、以第二蓝牙传输协议传输所述音频文件的音频信息至蓝牙设备。
在本发明实施例中，为了将音频数据存储至音频文件夹，可以在发送音频数据的同时或前后间隔一段时间，也可以在发送缓存开始指令的同时或前后间隔一段时间，或者，在发送缓存结束指令的同时或前后间隔一段时间，通过BLE发送音频信息至蓝牙设备。
需要说明的是，在本发明实施例中，上述各步骤301、302、303、304之间并不必然存在一定的先后顺序，本领域普通技术人员，根据本发明实施例的描述可以理解，不同实施例中，上述各步骤301、302、303、304可以有不同的执行顺序。同时，对于缓存开始指令及缓存结束指令在不同的实施例中，可以同时存在，也可以仅存在一种指令，比如，可以发送缓存开始指令及缓存结束指令，也可以仅发送缓存结束指令或缓存开始指令。
在本发明实施例中，所述方法还包括：
接收通信事件，并根据预先设置的优先级确定是否响应所述通信事件。
在本发明实施例中，用户终端设备在播放音频文件过程中，可以接收通信事件，比如，来电或者即时消息，对于不同的通信事件，可以预先设置优先级，用于确定是否响应相应的通信事件，比如，来电的优先级高于音频文件播放优先级，则当在播放音频文件过程中，如果接收到来电事件，可以终止音频文件 的传输，而响应该来电事件。当然，也可以设置通信事件的优先级低于音频文件的传输，比如，即时消息的优先级低于音频文件的播放优先级，则当在播放音频文件过程中，如果接收到即时消息，则可以不终止音频文件的传输。
本发明实施例，通过第一蓝牙音频传输协议传输音频文件的音频数据并通过第二蓝牙传输协议传输音频文件的音频信息至蓝牙设备，以提供音频文件给蓝牙设备，从而丰富音频文件的播放方式，提升用户体验，同时，通过传输缓存开始指令以及缓存结束指令有利于控制音频数据的存储，以提高音频数据的传输速度。
图4为本发明实施例提供的一种音频文件接收方法流程示意图，所述可以由图1所示的各种蓝牙设备执行，如图4所示，所述方法包括：
401：以第一蓝牙音频传输协议接收音频文件的音频数据。
在本发明实施例中，蓝牙设备可以通过A2DP接收用户终端设备发送的音频文件音频数据，该音频数据包含多个数据帧。
402：以第二蓝牙传输协议接收所述音频文件的音频信息。
在本发明实施例中，蓝牙设备可以通过BLE接收用户终端设备发送的音频文件的音频信息，音频信息用于建立音频文件夹，音频信息可以包括歌曲名称、歌手名称和/或歌曲类别，而且，音频信息与音频数据属于同一音频文件。
需要说明的是，在本发明实施例中，上述步骤401、402之间并不必然存在一定的先后顺序，本领域普通技术人员，根据本发明实施例的描述可以理解，不同实施例中，上述步骤401与402可以有不同的执行顺序。
本发明实施例，通过第一蓝牙音频传输协议接收音频文件的音频数据并通过第二蓝牙传输协议接收音频文件的音频信息至蓝牙设备，以便于蓝牙设备存储音频文件，从而丰富音频文件的播放方式，提升用户体验。

505、以所述第二蓝牙传输协议接收缓存结束指令。
在本发明实施例中，当缓存的音频数据达到预设静态随机存取存储器的存储容量时，或者，音频文件的音频数据传输完成，可以通过BLE传输缓存结束指令至蓝牙设备，蓝牙设备在可以通过BLE接收缓存结束指令时，终止音频数据在缓存中的存储。
需要说明的是，在本发明实施例中，上述步骤501、502、503、504、505之间并不必然存在一定的先后顺序，本领域普通技术人员，根据本发明实施例的描述可以理解，不同实施例中，上述步骤501、502、503、504、505可以有不同的执行顺序，同时，对于缓存开始指令及缓存结束指令在不同的实施例中， 可以同时存在，也可以仅存在一种指令，比如，可以接收缓存开始指令及缓存结束指令，也可以仅接收缓存结束指令或缓存开始指令。
本发明实施例，通过第一蓝牙音频传输协议接收音频文件的音频数据并通过第二蓝牙传输协议接收音频文件的音频信息至蓝牙设备，以便于蓝牙设备存储音频文件，从而丰富音频文件的播放方式，提升用户体验。同时，通过接收缓存开始指令以及缓存结束指令有利于控制音频数据的存储，以提高音频数据的传输速度，而且，将音频文件存储至音频文件夹，方便用户直接通过蓝牙设备播放音频文件。
为进一步说明本发明音频文件传输方法及音频文件接收方法实施例，下面结合具体的应用场景对本发明音频文件传输方法及音频文件接收方法进行举例说明。该具体应用场景为通过手机向蓝牙耳机进行音乐播放，如图6所示，为本发明实施例手机和蓝牙耳机之间的音频文件处理工作流程示意图，该应用实施例具体包括:
1、手机通过音乐APP播放音乐文件，如播放一首MP3格式歌曲；
2、手机将MP3格式转化为PCM格式；
3、手机的蓝牙IC将PCM格式编码为SBC、AAC、Apt-X等格式，并将该格式的音乐分成一帧一帧的，如frame1、frame2……frameN；
4、手机发送开始缓存指令给蓝牙耳机，将frame1、frame2……frameN的音乐通过A2DP传输至蓝牙耳机，蓝牙耳机接收frame1、frame2……frameN并缓存于其Memory内。在此先存入Memory中而不直接缓写入歌曲文件夹内，是因为Memory为SRAM(静态随机存取存储器)，存储快，节省时间且节省功耗；
5、手机将本首歌的音乐信息(如歌曲名称、歌手名称、歌曲类别等)通过BLE传输至蓝牙耳机；并在蓝牙耳机的存储器内建立歌曲文件夹，如以歌手名称命名为文件夹名称；存储器为eMMC或TCard或UFS；
可选的，该步骤可与第4步骤同时进行。
6、当Memory中存储到一定数量的音乐帧时，蓝牙耳机开始将Memory中存有的音乐帧一帧一帧地写入歌曲文件夹中。
7、当音乐帧发送到最后一帧时，手机发送终止缓存指令给蓝牙耳机，蓝牙耳机将终止缓存写入歌曲文件夹中，从而终止缓存；
8、在另外一个实施例中，不用通过缓存，直接将第4步骤的音乐帧一帧一 帧通过A2DP写入歌曲文件夹中。
