1. Add 'ReaLimit' FX to master track.
2. Add 'Loudness Meter Peak/RMS/LUF' FX to master track.
3. Adjust the threshold in the limiter, until LUFS-I in meter is what you want.
4. To hear the effect of the limiter threshold without the change in volume, check the Link option.
5. These two plugins use quite a bit of CPU, so should be disabled until rendering is required.

Generally speaking, it is recommended to aim for a range between -14 and -16 dB LUFS.

• Preview (dry run) render. Ideally:
  • Peak -0.1
  • Clip: 0
  • LUFS-I: Refer to table
• To prevent clipping:
  • Add JS: Event Horizon Limiter/Clipper to master track.
  • Threshold: 0.0 (no change in LUFS-I) or decrease to make louder
  • Ceiling: -0.1
  • Release: 0.0
• 2nd pass render: checked
• Resample mode: r8brain free
• Normalize ON, LUFS-I, -10 LU Make sure the track is mastered correctly as above.
• Format: MP3 (encoder by LAME project)
• Mode: Target quality (VBR), Maximum q=0 (slow)
• Quality: 70

This trick will enable you to hear the effect of the limiter without changing the volume.

1. Add JS: Event Horizon Limiter/Clipper to master track.
2. Threshold: 0.0
3. Ceiling: -0.0
4. Release: 0.0
5. Select Edit button.
6. Scroll down to @slider.
7. Add slider2=slider1; afterwards.
8. Threshold & Ceiling are now linked. Decrease the Threshold to hear the artifacts of the limiter.
