在相关技术中，电子设备在向音频输出设备传输音频数据，以通过接收端设备进行音频播放时，电子设备通常需要先对音源数据进行一系列的编解码处理。示例性地，图1A为相关技术中音频数据传输的示意图。如图1A所示，以电子设备通过蓝牙无线通信，向音频输出设备传输音频数据进行播放为例，电子设备获取音源数据，可先对音源数据进行PCM(Pulse Code Modulation，脉冲编码调制)解码，得到PCM数据，再对PCM数据进行SBC(Sub Band Coding，子带编码)、AAC(Advanced Audio Coding，高级音频编码)等蓝牙音频编码处理，以得到SBC、AAC等编码格式的蓝牙音频编码数据。电子设备可将SBC、AAC等编码格式的蓝牙音频编码数据通过蓝牙无线通信传输给音频输出设备，音频输出设备对BC、AAC等编码格式的蓝牙音频编码数据进行PCM解码，得到PCM数据，再利用DAC(Digital to Analog converter，数模转换器)及AMP(Amplifier for Power，功率放大器)进行数模转换及功率放大，得到模拟数据，从而对模拟数据进行播放。
由于电子设备会先将音源数据解码为PCM数据，再进行SBC、AAC等编码处理，该SBC、AAC等编码处理是有损音频编码技术，从而会导致音源数据的音频品质损失，严重影响音频的播放效果，导致用户无法成功体验到音源数据的无损播放效果。

在本申请实施例中，电子设备直接对音源数据的帧原始音频包进行封装，得到数据格式符合通信协议的目标音频数据包，而不需要对帧原始音频包进行PCM解码及SBC、AAC等编码处理，既可避免帧原始音频包在编解码过程中出现音乐品质损失，又可节省处理时间及功耗，且编包过程简单，节省了电子设备的计算力及消耗的内存等资源，实现了零压缩、低功耗、低延迟的无损品质音频传输。
步骤220，将目标音频数据包经由无线通信信道发送至音频输出设备。
电子设备可将封装得到的目标音频数据包发送给音频输出设备，音频输出设备接收到该目标音频数据包后，可对该目标音频数据包进行解包，得到帧原始音频包，再对该帧原始音频包进行处理，以播放处理得到的音频数据。在一些实施例中，音频输出设备可先从目标音频数据包中提取通信协议的指示部，根据该通信协议的指示部可识别到该目标音频数据包为符合通信协议规定的音频数据包，音频输出设备可再基于通信协议从目标音频数据包中提取帧原始音频包，然后对提取的帧原始音频包进行处理，以播放处理得到的音频数据。由于在整个传输的过程中帧原始音频包不会经历有损压缩编码等过程，因此，音频输出设备能够播放无损音乐品质的音频数据，提高了音频播放效果。
在一些实施例中，音频输出设备可对从目标音频数据包中提取的帧原始音频包进行PCM解码，得到PCM解码数据，再对该PCM解码数据进行数模转换，得到第一模拟数据，并对第一模拟数据进行功率放大，得到第二模拟数据。音频输出设备可输出该第二模拟数据。
