async playInterlude(section) {
const duration = this.calculateInterludeDuration(section);
// 生成纯音乐间奏
await this.generateInstrumentalMusic(this.currentInstrument, duration);
// 自动等待间奏结束后继续演唱
}
```
4. 本地数据存储
```javascript
savePresets() {
const presets = {
voice: this.currentVoice,
instrument: this.currentInstrument,
bpm: this.bpm,
emotionProfile: this.emotionProfile
};
localStorage.setItem('ttsPresets', JSON.stringify(presets));
}
```
🎹 使用指南
1. 基础操作流程
1. 选择发音人 - 点击侧边栏选择声音类型
2. 选择乐器 - 选择伴奏乐器
3. 调整情感 - 使用滑块调整情感参数
4. 编辑歌词 - 在编辑器中输入带标记的歌词
5. 播放 - 点击播放按钮开始合成
2. 高级功能使用
· 歌曲结构: 使用 [主歌]、[副歌] 等标记定义结构
· 间奏控制: 使用 等待4小节 等指令控制间奏
· 情感微调: 实时调整情感滑块影响演唱风格
· BPM控制: 调整节奏速度影响整体时长
3. 专业特性
· 自动和声: 系统根据段落自动生成合适的和声
· 情感智能: 情感参数智能影响语音合成和音乐生成
· 段落识别: 自动识别和处理不同歌曲段落
· 可视化反馈: 实时显示音频波形和频谱
这个专业级系统提供了接近商业音乐制作软件的体验,集成了语音合成、音乐制作、情感控制和可视化等高级功能。您可以根据需要进一步扩展数据库、添加更多乐器或优化算法。
