音频插件方案

1. LV2
2. vsti
3. SDL2 自研发技术（SimpleLoops i）(仿FL i 插件格式）

The issue lists three audio plugin architectures (LV2, VSTi, and a custom SDL2-based format) but provides no specific implementation details or code pointers. Research would start by examining the existing SimpleLoops codebase for any audio plugin infrastructure, then comparing the listed technologies to understand integration requirements. 'Done' would be a design proposal or prototype, but the scope is large and undefined.
