+# Open-XiaoAI Stereo
+
+不同型号的小爱音箱组立体声。
+
+## 功能
+
+- 在小爱音箱上独立运行，无需服务端部署
+- 支持不同型号的小爱音箱局域网组立体声
+- 支持蓝牙播放和小爱音箱自带的音乐播放
+- 支持局域网内主从设备服务发现自动连接
+- 支持主从节点“热拔插”，自动切换声道
+- 支持前向纠错(FEC)和丢包补偿(PLC)
+
+## 快速开始
+
+> [!NOTE]
+> 以下操作需要先将小爱音箱刷机， 然后 SSH 连接到小爱音箱。👉 [教程](../../docs/flash.md)
+
+首先，分别在两台设备上配置主从和声道。
+
+```shell
+# 首先确保配置文件路径存在
+mkdir -p /data/open-xiaoai || true
+
+# 如果你想让左边的小爱音箱作为主音源
+echo master left > /data/open-xiaoai/stereo.conf # 在左边的小爱音箱上执行
+echo slave right > /data/open-xiaoai/stereo.conf # 在右边的小爱音箱上执行
+
+# 如果你想让右边的小爱音箱作为主音源
+# echo master right > /data/open-xiaoai/stereo.conf # 在右边的小爱音箱上执行
+# echo slave left > /data/open-xiaoai/stereo.conf # 在左边的小爱音箱上执行
+```
+
+配置完成后，分别在两台设备上运行下面的启动脚本即可。
+
+```shell
+curl -sSfL https://gitee.com/idootop/artifacts/releases/download/open-xiaoai-stereo/init.sh | sh
+```
+
+如果你想要开机自启动，运行以下命令重启小爱音箱即可（需要先按上面的步骤配置主从设备和声道）。
+
+```shell
+# 下载 boot.sh 到 /data/init.sh 开机时自启动
+curl -L -o /data/init.sh https://gitee.com/idootop/artifacts/releases/download/open-xiaoai-stereo/boot.sh
+
+# 重启小爱音箱
+reboot
+```
+
+## 注意事项
+
+- 不支持同步音量大小（不同型号设备的音量基准不同，请手动调整）
+- 不支持多路音频混音（同时播放多个音频听起来像是信号故障、静音卡顿）
+- 目前只支持小爱音箱 Pro（LX06）和小米智能音箱 Pro（OH2P）这两个机型（需要刷机）
+- 从设备会主动同步主设备的音源，反之不支持（建议禁用从设备的麦克风和操作，防止音频叠加）
