# 202008projects IR / Impulse Response 使用扫描

## 结论

- 已新增扫描脚本：`scan_rpp_ir_usage.py`
- 已生成 JSON 报告：`reamixed_project_files/202008projects/ir_usage_report.json`
- 扫描结果：
  - 共扫描 `13` 个 `RPP`
  - 其中 `6` 个项目目录包含本地 `IR / Impulse Responses`
  - 这 `6` 个项目都确实在工程中调用了本地 IR
  - 共发现本地 IR 文件 `18` 个，已被引用 `18` 个

## 为什么“不用连 REAPER 也能查”

- 普通媒体源引用会直接写在 `.rpp` 的 `FILE "..."` 行里
- `ReaVerb` 这类插件的 IR 路径通常藏在插件状态块里
- 该状态块在 `.rpp` 中通常表现为：
  - 一个 `<VST "VST: ReaVerb (Cockos)" ...>` 头
  - 后面若干行 `base64` 文本
  - 解码后能在二进制里找到形如 `/.../Impulse Responses/...wav` 的真实路径字符串

## 实际例子

- `reamixed_project_files/202008projects/XYBERSAW_EricRacy_Higher_Mix/EricRacy_Higher_Mix.RPP:954`
- 同一插件块后续几行里存的是 `base64`
- 解码后可提取出：
  - `Impulse Responses/MRV_RV_AbbeyPlate.wav`
