🔧 Troubleshooting

Häufige Probleme & Lösungen

Audio-System Probleme

Problem Symptom Lösung
Mikrofon nicht erkannt "Audio device not found" node debug-microphone.js
SoX Installation "sox command not found" brew install sox (macOS)
Permissions "Microphone access denied" System Preferences → Privacy
Audio Quality Schlechte Transkription Externes USB-Mikrofon verwenden

Whisper-spezifische Probleme

# Whisper Installation prüfen
whisper --help

# Modell-Download forcieren
whisper test.wav --model base --language German

# Python PATH prüfen
which python
python -m pip show openai-whisper

# Alternative Installation
pip uninstall openai-whisper
pip install openai-whisper --force-reinstall

Memory & Performance Issues

# Memory Usage überwachen
node --max-old-space-size=4096 live-mode.js

# Context regelmäßig cleanen
# Voice Command: "Neue session"

# Chunk-Size reduzieren (config.json)
{
  "audio": {
    "chunkDuration": 3000,  // von 2000 auf 3000
    "contextWindow": 900000  // 15 min statt 30 min
  }
}

Emergency Stop Procedures

Live Mode Stoppen (Prioritätsreihenfolge)

  1. Keyboard Commands (Terminal):

    Ctrl+C          # Graceful stop (Empfohlen)
    Cmd+C           # macOS alternative
  2. Voice Commands:

    • "Meeting ende"
    • "Session ende"
    • "Stop listening"
  3. Process Kill (Notfall):

    # Prozesse finden
    ps aux | grep -E "(live-mode|sox|whisper)"
    
    # Graceful kill
    kill -TERM <PROCESS_ID>
    
    # Force kill (letzter Ausweg)
    kill -9 <PROCESS_ID>
    
    # Alle Node.js Live-Prozesse stoppen
    pkill -f "node.*live"
  4. Cleanup nach Force Kill:

    # Temp-Dateien aufräumen
    rm -rf temp-audio/*
    rm -rf recordings/*
    
    # Audio-Prozesse prüfen
    pkill -f "sox.*coreaudio"
    pkill -f "whisper"
