## Supported Formats / 支持格式

### ⚡ Metal GPU Acceleration (NEW)

On Apple Silicon, `whisper-cpp` provides 15-20x faster transcription:

| Audio | CPU (openai-whisper) | Metal GPU (whisper-cpp) |
|-------|---------------------|------------------------|
| 5 min | ~5 min | ~20 sec |
| 30 min | ~30 min | ~2 min |
| 60 min | ~60 min | ~4 min |

```bash
# Install for Metal acceleration (recommended)
brew install whisper-cpp
```

The skill auto-detects and uses Metal when available.

| Type / 类型 | Formats / 格式 | Processing / 处理方式 |
|-------------|----------------|----------------------|
| Voice Memos | .qta, .m4a | Apple native (QTA metadata) → Whisper fallback |
| Audio | .mp3, .wav, .aac, .flac | Whisper local transcription |
| Video | .mp4, .mov, .mkv, .webm | ffmpeg extract → Whisper |
| YouTube | URL | summarize CLI → yt-dlp fallback |
| Bilibili | URL | yt-dlp download → Whisper |
| Text | .txt, .md | Direct read, skip transcription |
| Documents | .doc, .docx | textutil convert → process |
| Structured | .json, .csv | Parse and extract text |
| iCloud | Configured paths | Scheduled sync |

## QTA File Format / QTA文件格式 (Technical Reference)

Apple Voice Memos on iOS/macOS 14+ uses `.qta` (QuickTime Audio) files that embed native transcription directly in the file metadata.

### Structure
```
QTA File
├── ftyp (file type marker: "qt  ")
├── wide (extended marker)
├── mdat (audio data, typically 90%+ of file size)
└── moov (metadata container)
    ├── mvhd (movie header)
    └── trak (one or more tracks)
        ├── tkhd (track header)
        ├── mdia (media data)
        └── meta (metadata - TRANSCRIPTION HERE!)
            ├── hdlr (handler: "mdta")
            ├── keys (key list: "com.apple.VoiceMemos.tsrp")
            └── ilst (data list)
                └── data (JSON transcription payload)
```

### Transcription JSON Format
```json
{
  "locale": {"identifier": "zh-Hans_GB", "current": 1},
  "attributedString": {
    "runs": ["字",0,"符",1,"转",2,"录",3,...],
    "attributeTable": [
      {"timeRange": [0.0, 0.5]},
      {"timeRange": [0.5, 0.8]},
      ...
    ]
  }
}
```

**Key Points:**
- `runs` array alternates: `[text, index, text, index, ...]`
- `attributeTable` provides timestamps for each character
- JSON is embedded raw in the `ilst/data` atom
- Use `extract-apple-transcript.py` to reliably extract

### Extraction Script
```bash
# Extract plain text
python3 scripts/extract-apple-transcript.py recording.qta

# Extract with metadata (JSON output)
python3 scripts/extract-apple-transcript.py recording.qta --json

# Extract with timestamps
python3 scripts/extract-apple-transcript.py recording.qta --json --with-timestamps
```

### Common Issues
| Issue | Cause | Solution |
|-------|-------|----------|
| "未找到转录数据" | Recording still processing | Wait 1-2 min, or use Whisper |
| "转录标记存在但数据不完整" | Partial transcription | Use Whisper fallback |
| JSON parse error | Corrupted file | Try Whisper transcription |

## Agent Processing Guide / Agent处理指南

When user sends audio/video or URL, follow these steps:  
当用户发送音视频或URL时，按以下步骤处理：

### Step 1: Detect Input Type / 识别输入类型
```
YouTube URL      → summarize extract
Bilibili URL     → yt-dlp download + whisper
.qta/.m4a        → Apple transcript extraction
Other audio/video → whisper transcription
.txt/.md file    → direct read
.doc/.docx       → textutil convert
```

### Step 2: Save Source Info / 保存源信息
```bash
# Record to memory/voice-memos/sources/
echo '{"input":"...", "type":"...", "date":"YYYY-MM-DD"}' > sources/xxx.json
```

### Step 3: Get/Save Transcript / 获取保存转录
```bash
# Save to memory/voice-memos/transcripts/YYYY-MM-DD_source_title.md
# Include: source info + full raw transcript
```

### Step 4: LLM Deep Processing / LLM深度整理
```
Read USER.md and MEMORY.md, combining user context.

**TWO-PASS PROCESSING for Long Content (> 60 min):**
- Pass 1 (Quick Scan): Identify structure type, speaker presence, topic shifts
- Pass 2 (Deep Process): Apply appropriate mode to each segment

**OUTPUT DENSITY LEVELS (User can request):**
- Level 1: Executive Only (1 page, for busy stakeholders)
- Level 2: Structured Summary (5-10 pages, default)
- Level 3: Full Annotated Transcript (everything, with margin notes)
```

### Step 5: Save Processed Result / 保存处理结果
```bash
# Save to memory/voice-memos/processed/YYYY-MM-DD_source_title.md
```

### Step 6: Sync to Apple Notes (MANDATORY) / 同步到Apple Notes（必须执行）

⚠️ **CRITICAL: This step is MANDATORY. Never skip it.**  
⚠️ **关键：此步骤必须执行，不可跳过。**

⚠️ **Apple Notes requires HTML format, NOT Markdown!**  
⚠️ **Apple Notes 需要 HTML 格式，不能直接用 Markdown！**

**Correct workflow / 正确流程:**
```bash
# 1. Convert Markdown to HTML using pandoc (REQUIRED)
pandoc /path/to/processed.md -f markdown -t html -o /tmp/note-content.html

# 2. Create note with HTML content via AppleScript
osascript <<'EOF'
set htmlContent to do shell script "cat /tmp/note-content.html"
set noteTitle to "🎙️ Note Title"

tell application "Notes"
    set folderName to "Voice Memos"
    set targetFolder to missing value
    
    repeat with f in folders
        if name of f is folderName then
            set targetFolder to f
            exit repeat
        end if
    end repeat
    
    if targetFolder is missing value then
        make new folder with properties {name:folderName}
        delay 1
        set targetFolder to folder folderName
    end if
    
    tell targetFolder
        make new note with properties {name:noteTitle, body:htmlContent}
    end tell
end tell
EOF
```

**Common mistakes to avoid / 常见错误:**
- ❌ Writing raw Markdown to Apple Notes → 乱码/格式错误
- ❌ Using `memo notes -a` interactively → 无法自动化
- ❌ Skipping this step entirely → 其他设备看不到
- ✅ Always convert MD → HTML via pandoc first
- ✅ Always verify the note was created successfully

### Step 7: Create Reminders / 创建提醒
```bash
remindctl add --title "TODO" --list "Reminders" --due "YYYY-MM-DD"
```

### Step 8: Update INDEX.md / 更新索引
```bash
# Append record to memory/voice-memos/INDEX.md
```

## Privacy / 隐私说明

⚠️ **Privacy-First Design:**
- All transcription runs locally by default / 所有转录默认在本地完成
- Apple native transcripts extracted from local files / Apple原生转录从本地文件提取
- Whisper runs locally / Whisper在本地运行
- No data sent to external servers (unless user explicitly configures external API)
- User data stored only in local memory directory

---

## Troubleshooting / 故障排除

### Whisper not found
```bash
brew install openai-whisper
```

### yt-dlp download fails
```bash
# Update yt-dlp
brew upgrade yt-dlp

# Or use proxy
export ALL_PROXY=http://127.0.0.1:7890
```

### Apple Notes folder not created
```bash
# Manually create via AppleScript
osascript -e 'tell application "Notes" to tell account "iCloud" to make new folder with properties {name:"Voice Memos"}'
```

### Transcription quality issues
```bash
# Use larger model for better accuracy
# Edit config: whisper_model: "medium" or "large"
```
