# 代码简明规范 |
|
||||
## Dart / Flutter |
|
||||
1. 风格统一 |
|
||||
• 严格遵循 Effective Dart 格式与命名惯例。 |
|
||||
2. 日志与调试 |
|
||||
• 禁止 print；仅在异常场景调用 logger.e(...)。 |
|
||||
3. 业务逻辑 |
|
||||
• 默认使用 GetX（状态、路由、依赖注入等），避免手写 StatefulWidget。 |
|
||||
4. 异常处理 |
|
||||
• 不写重试逻辑，失败即返回错误。 |
|
||||
• 谨慎使用 try-catch；优先通过类型系统与空安全防御。 |
|
||||
5. 代码演进 |
|
||||
• 任何改动都应 “小步、安全”，杜绝一次性大改或过度设计。 |
|
||||
|
|
||||
## 原生层（Android / iOS） |
|
||||
1. 配置不可改 |
|
||||
• 禁止修改 SDK、NDK、JDK 与 iOS 构建配置。 |
|
||||
2. Kotlin DSL |
|
||||
• 原生实现一律采用 Kotlin + 协程，遵守 Kotlin 最佳实践。 |
|
||||
• 不写 Java 代码。 |
|
||||
|
|
||||
## 通用要求 |
|
||||
1. 不自动执行 |
|
||||
• 生成脚本/代码不得包含 flutter run 等执行指令。 |
|
||||
2. 并发优先级 |
|
||||
• 并发场景首选 Kotlin 协程；仅在 Flutter 端按需使用 Dart Future / Stream。 |
|
||||
3. 语言 |
|
||||
• 与用户交流、注释及文档一律使用中文。 |
|
||||
• 不要自己创建总结文档。 |
|
||||
|
|
||||
宗旨：保持极简，先跑通业务，再考虑优化。 |
|
||||

# 项目架构概述 |
|
||||
DeepSound是一个基于Flutter和GetX构建的多平台语音应用，具有语音合成、语音识别、语音聊天等功能。 |
|
||||
|
|
||||
## 总体架构 |
|
||||
- 采用GetX状态管理框架 |
|
||||
- 遵循模块化设计，各功能模块相对独立 |
|
||||
- 使用依赖注入实现组件解耦 |
|
||||
- 多语言支持，使用GetX国际化方案 |
|
||||
|
|
||||
## 主要目录结构 |
|
||||
- lib/core: 核心组件、工具和通用功能 |
|
||||
- lib/data: 数据模型、服务和提供者 |
|
||||
- lib/modules: 功能模块，按业务划分 |
|
||||
- lib/routes: 路由定义和管理 |
|
||||
- local_plugins: 本地插件，提供原生功能支持 |
|
||||
|
|
||||
# 核心模块说明 |
|
||||
## 语音处理 |
|
||||
- 火山语音服务: 提供语音识别和合成核心能力 |
|
||||
- Azure语音服务: 提供备选的语音识别和合成能力 |
|
||||
- 离线TTS支持: 在线语音合成失败时的备选方案 |
|
||||
|
|
||||
## 聊天功能 |
|
||||
- 基于OpenAI的对话功能 |
|
||||
- 支持语音输入、文字输入和语音输出 |
|
||||
- 支持多种角色和语音类型 |
|
||||
|
|
||||
## 用户系统 |
|
||||
- 支持多种登录方式：Firebase、Google、Facebook |
|
||||
- 用户资料管理和设置 |
|
||||
- 主题切换和语言设置 |
|
||||
|
|
||||
## 蓝牙配对 |
|
||||
- 支持蓝牙设备发现和连接 |
|
||||
- 提供简化的配对流程 |
|
||||
- 设备管理和状态监控 |
|
||||
|
|
||||
## 音频处理 |
|
||||
- 音频录制和播放 |
|
||||
- 支持波形显示 |
|
||||
- 音量控制和音频质量设置 |
|
||||
|
|
||||
# 技术栈 |
|
||||
- Flutter: UI框架 |
|
||||
- GetX: 状态管理和依赖注入 |
|
||||
- Firebase: 用户认证和后端服务 |
|
||||
- WebSocket: 实时通信 |
|
||||
- SQLite: 本地数据存储 |
|
||||
- 原生插件: 语音识别、合成和蓝牙功能 |
|
||||
|
|
||||
# 插件说明 |
|
||||
- jieli: 杰理蓝牙设备连接和控制插件 |
|
||||
- volcano_speech: 火山语音服务插件，提供语音识别和合成 |
|
||||
- azure_speech: 微软Azure语音服务插件 |
|
||||
- open_ai_service: OpenAI服务插件，提供AI对话能力 |
|
||||
- speech_to_text: 通用语音识别插件 |
|
||||
|
|
||||
# 环境配置 |
|
||||
- 环境变量通过.env文件管理 |
|
||||
- 支持不同环境的配置切换 |
|
||||
- 敏感信息不应直接硬编码在代码中 |

# JL OPUS Plugin |
||||
|
|
||||
|
基于杰理音频编解码库的Flutter插件，提供OPUS音频格式的解码功能。 |
||||
|
|
||||
|
## 功能 |
||||
|
|
||||
|
- 支持OPUS文件解码为PCM格式 |
||||
|
- 支持OPUS数据流解码 |
||||
|
- 支持多种采样率和通道配置 |
||||
|
- 支持带协议头/不带协议头的OPUS数据 |
||||
|
|
||||
|
## 引入方式 |
||||
|
|
||||
|
在pubspec.yaml中添加依赖： |
||||
|
|
||||
|
```yaml |
||||
|
dependencies: |
||||
|
jl_opus: |
||||
|
path: ./local_plugins/jl_opus |
||||
|
``` |
||||
|
|
||||
|
## 使用方法 |
||||
|
|
||||
|
### 初始化插件 |
||||
|
|
||||
|
```dart |
||||
|
import 'package:jl_opus/jl_opus.dart'; |
||||
|
|
||||
|
final jlOpus = JlOpus(); |
||||
|
``` |
||||
|
|
||||
|
### 解码OPUS文件 |
||||
|
|
||||
|
```dart |
||||
|
Future<void> decodeOpusFile() async { |
||||
|
final inPath = '/path/to/input.opus'; |
||||
|
final outPath = '/path/to/output.pcm'; |
||||
|
|
||||
|
// 创建解码选项 |
||||
|
final option = OpusOption( |
||||
|
hasHeader: false, // 是否有协议头 |
||||
|
channel: 1, // 通道数：1=单声道，2=立体声 |
||||
|
sampleRate: 16000, // 采样率 |
||||
|
packetSize: 40, // 数据包大小（仅当hasHeader=false时生效） |
||||
|
); |
||||
|
|
||||
|
try { |
||||
|
// 开始解码文件 |
||||
|
final outFilePath = await jlOpus.decodeOpusFile(inPath, outPath, option); |
||||
|
print('解码成功: $outFilePath'); |
||||
|
} catch (e) { |
||||
|
print('解码失败: $e'); |
||||
|
} |
||||
|
} |
||||
|
``` |
||||
|
|
||||
|
### 解码OPUS数据流 |
||||
|
|
||||
|
```dart |
||||
|
Future<void> decodeOpusStream() async { |
||||
|
// 监听解码后的PCM数据 |
||||
|
jlOpus.decodedDataStream.listen((pcmData) { |
||||
|
print('收到解码后的PCM数据: ${pcmData.length} 字节'); |
||||
|
// 处理解码后的PCM数据 |
||||
|
}); |
||||
|
|
||||
|
// 创建解码选项 |
||||
|
final option = OpusOption( |
||||
|
hasHeader: false, |
||||
|
channel: 1, |
||||
|
sampleRate: 16000, |
||||
|
packetSize: 40, |
||||
|
); |
||||
|
|
||||
|
// 开始解码数据流 |
||||
|
final success = await jlOpus.startDecodeStream(option); |
||||
|
if (success) { |
||||
|
print('开始解码数据流'); |
||||
|
|
||||
|
// 写入OPUS数据进行解码 |
||||
|
final opusData = Uint8List.fromList([/* OPUS数据 */]); |
||||
|
await jlOpus.writeAudioStream(opusData); |
||||
|
|
||||
|
// 数据处理完成后停止解码 |
||||
|
await jlOpus.stopDecodeStream(); |
||||
|
} |
||||
|
} |
||||
|
``` |
||||
|
|
||||
|
### 监听事件 |
||||
|
|
||||
|
```dart |
||||
|
void listenToEvents() { |
||||
|
jlOpus.eventStream.listen((event) { |
||||
|
switch (event.event) { |
||||
|
case 'onStart': |
||||
|
print('开始${event.type == "file" ? "文件" : "流"}解码'); |
||||
|
break; |
||||
|
case 'onComplete': |
||||
|
print('完成${event.type == "file" ? "文件" : "流"}解码'); |
||||
|
if (event.filePath != null) { |
||||
|
print('输出文件: ${event.filePath}'); |
||||
|
} |
||||
|
break; |
||||
|
case 'onError': |
||||
|
print('解码错误: [${event.errorCode}] ${event.errorMessage}'); |
||||
|
break; |
||||
|
} |
||||
|
}); |
||||
|
} |
||||
|
``` |
||||
|
|
||||
|
### 资源释放 |
||||
|
|
||||
|
```dart |
||||
|
Future<void> disposePlugin() async { |
||||
|
await jlOpus.dispose(); |
||||
|
print('插件资源已释放'); |
||||
|
} |
||||
|
``` |
||||
|
|
||||
|
## 注意事项 |
||||
|
|
||||
|
1. OPUS解码需要正确设置参数，特别是采样率和通道数必须与原始音频匹配 |
||||
|
2. 使用前请确保jl_audio_decode_V2.0.0_20005.aar包已添加到libs目录 |
||||
|
3. 本插件仅支持Android平台 |
