Fouad's Iron Limiter

Loud, Clean, Transparent

Iron Limiter is an intelligent peak limiter designed for maximum loudness with zero compromise. Advanced adaptive release, 4x oversampling, and lookahead processing deliver results that are loud, clean, and free from pumping artifacts.

Why Iron Limiter?

Most limiters force you to choose between loudness and quality. Iron Limiter eliminates that trade-off with intelligent release behavior that automatically adapts to your material—surgical on transients, smooth on sustained sections. Push your masters to -6/-5 LUFS and beyond while keeping everything clean and transparent.

What's Inside

Three Intuitive Controls — Everything you need, nothing you don't:

• INPUT GAIN — Drive your signal into the limiter (0 to +20 dB) to control how much limiting is applied
• CEILING — Set your output ceiling from -12 to 0 dB. Default -0.5 dB is perfect for streaming platforms
• SMOOTHING — Blend between surgical peak catching (0) and smooth sustained gain reduction (1). Start at 0 for maximum loudness

Intelligent Adaptive Release — Iron Limiter's release automatically adapts to your material in real time. Fast transients get caught surgically without affecting the surrounding audio, while sustained passages remain smooth and pump-free. No need to manually dial in release times—the algorithm handles it for you.

4x Oversampling — Internal oversampling reduces aliasing artifacts from gain changes, ensuring your limited signal stays clean and natural even under heavy gain reduction.

Lookahead Processing — Gain is computed ahead of the audio, eliminating clicks and ensuring perfectly transparent attack behavior on every transient.

Professional Monitoring — Real-time gain reduction meter shows exactly how hard you're limiting. Short-term LUFS meter (ITU-R BS.1770 compliant) lets you dial in your target loudness with precision. Delta mode lets you hear exactly what the limiter is removing, and Gain Match removes loudness bias for honest A/B comparison.

Built for Loudness

Iron Limiter is designed to go loud. Combined with Iron Clip, you can easily push your masters to -6/-5 LUFS while maintaining clarity and punch. The clipper handles peak reduction, the limiter handles final loudness—a combo that's more transparent than heavy limiting alone.

Recommended Signal Chain

ToneMatch EQ (tone shaping) → EQ → Iron Clip (clipping) → Iron Limiter (final loudness & ceiling)

Simple, Powerful, Transparent

No complex menus. No hidden settings. Three knobs, two buttons, and a limiter that just works. Insert it, push the input gain, and hear your track get louder without getting worse.
