🎤 Usage Tips & Best Practices

Recording Tips

  • Monitor Levels: Keep input levels around -12dB to -18dB
  • Use Headphones: Prevent feedback when monitoring
  • Record Dry: Apply Dubler 2 during recording, not after
  • Test Settings: Try different presets before recording
  • Multiple Takes: Record several versions with different settings

Plugin Settings

  • Subtlety: Start with subtle settings for natural sound
  • Voice Count: Use 2 voices for thickness, 4 for choir effects
  • Pitch Variation: Small amounts (5-10 cents) sound most natural
  • Timing Offset: 5-15ms delays prevent phase issues
  • Mix Level: Blend doubled vocals around 30-50%
