+# Opus Audio Codec Example
+
+This is a simple example project that demonstrates audio encoding and decoding using the Opus library. The project includes two programs: one for recording audio and encoding it into Opus format, and another for decoding and playing Opus audio.
+
+## Features
+
+- Uses the Opus library for audio encoding and decoding
+- Uses the ALSA library for audio device operations
+- Includes two separate programs: recording and playback
+
+## Build Requirements
+
+- CMake 3.10.0 or higher
+- Opus development libraries
+- ALSA development libraries
+
+## Build Instructions
+
+```bash
+mkdir build
+cd build
+cmake ..
+make
+```
+
+This will build two executable files: `record` and `play`.
+
+## Usage
+
+### Record Audio
+
+```bash
+./record
+```
+
+This records audio from the default audio input device, encodes it into Opus format, and saves it as a file named "record.opus".
+
+### Play Audio
+
+```bash
+./play
+```
+
+This plays the previously recorded "record.opus" file.
+
+## Code Structure
+
+- `record.c` - Recording program containing audio recording and Opus encoding logic
+- `play.c` - Playback program containing Opus decoding and audio playback logic
+- `CMakeLists.txt` - CMake build configuration file
+
+## License
+
+Please refer to the LICENSE file in the project for licensing information.

+# Opus 音频编解码示例
+
+这是一个使用 Opus 库进行音频编解码的简单示例项目。该项目包含两个程序：一个用于录制音频并将其编码为 Opus 格式，另一个用于解码并播放 Opus 音频。
+
+## 特性
+
+- 使用 Opus 库进行音频编码和解码
+- 使用 ALSA 库进行音频设备操作
+- 包含录制和播放两个独立程序
+
+## 构建要求
+
+- CMake 3.10.0 或更高版本
+- Opus 开发库
+- ALSA 开发库
+
+## 构建方法
+
+```bash
+mkdir build
+cd build
+cmake ..
+make
+```
+
+这将构建两个可执行文件：`record` 和 `play`。
+
+## 使用方法
+
+### 录制音频
+
+```bash
+./record
+```
+
+这将从默认音频输入设备录制音频，并将其编码为 Opus 格式，保存为 "record.opus" 文件。
+
+### 播放音频
+
+```bash
+./play
+```
+
+这将播放之前录制的 "record.opus" 文件。
+
+## 代码结构
+
+- `record.c` - 录制程序，包含音频录制和 Opus 编码逻辑
+- `play.c` - 播放程序，包含 Opus 解码和音频播放逻辑
+- `CMakeLists.txt` - CMake 构建配置文件
+
