🏗️ Phase 2: Architect (Permanent Tool)

For Podcasters/Editors.

Engineering Prompt:

**Role:** Python GUI Developer (PyQt6 Specialist)
**Task:** Create "Universal Audio Extractor" Desktop App

**Objective:** A batch tool to extract high-quality audio tracks from video collections.

**Tech Stack:**
* Language: Python 3.10+
* GUI Library: PyQt6 (Cross-platform)
* Processing: FFmpeg
* Packaging: PyInstaller

**Functional Requirements:**
1.  **UI Layout (PyQt6):**
    *   **Source:** Drag-and-drop area for video files or folders.
    *   **Output Settings:** Format Combobox (MP3, WAV, FLAC, AAC).
    *   **Quality:** Bitrate selection (128k, 192k, 320k) for lossy formats.
    *   **Console:** Log output view.

2.  **Core Logic:**
    *   Construct FFmpeg command: `ffmpeg -i input.mp4 -vn -c:a libmp3lame -b:a 192k output.mp3`.
    *   **Threading:** Run FFmpeg in `QProcess` to show real-time progress.

3.  **Deliverables:**
    *   `main.py`: Complete source code.
    *   `requirements.txt`: Dependencies.
    *   **Build Instructions:**
        *   Windows: `pyinstaller --onefile --noconsole main.py`
        *   macOS: `pyinstaller --windowed --noconsole main.py`
