Step-by-Step Guide
- Ensure your mix has -3 to -6 dBFS of headroom. No peaks should hit 0 dBFS before the limiter.
- Place the limiter as the final plugin on your master bus, after EQ and compression.
- Set the output ceiling to -1.0 dBFS to prevent inter-sample peaks and distortion.
- Lower the threshold until you achieve 2-4 dB of gain reduction on peaks. Listen for distortion.
- Use auto-release or set manually. Faster release = more punch. Slower = smoother.
- Measure integrated LUFS. Aim for -14 LUFS for streaming. Check dynamic range — aim for 8-12 DR.

Frequently Asked Questions
- How much gain reduction should I use on the limiter?
- For mastering, 2-4 dB of gain reduction is typical. More than 6 dB usually causes audible distortion and pumping. If you need more loudness, go back to the mix and fix balance issues rather than pushing the limiter harder.
- What is the difference between a limiter and a maximizer?
- A maximizer is a type of limiter optimized for loudness. It often includes additional processing like saturation or multi-band limiting. In practice, the terms are used interchangeably, though 'maximizer' usually implies a mastering-focused tool.
- Why set the ceiling to -1.0 dBFS instead of 0?
- Digital-to-analog converters and MP3 encoding can create inter-sample peaks that exceed 0 dBFS even when the digital file doesn't. A -1.0 dBFS ceiling prevents these peaks from causing distortion during playback and encoding.
- Can I use a limiter while mixing?
- You can use a limiter on the mix bus for reference, but remove it before exporting. Mixing into a limiter changes your perception of dynamics and can lead to poor mix decisions. Do your limiting during the mastering stage.
- What is true peak limiting?
- True peak limiting accounts for inter-sample peaks that occur between samples during digital-to-analog conversion. Standard peak meters miss these peaks. True peak limiting ensures no distortion occurs during playback, even with aggressive limiting.
- Why does my mastered track sound quieter than commercial releases?
- Commercial releases are often heavily limited (-6 to -8 LUFS), but this comes at the cost of dynamics. Streaming platforms normalize loudness anyway, so extremely loud masters get turned down. Aim for -14 LUFS and focus on mix quality over sheer loudness.
