Jeroen Breebaart has released Barricade, a simple yet effective brick wall limiter.
The gain ride curve is very smooth and its time derivative is continuous, to ensure minimum distortion and aliasing artefacts. The drive knob adjusts the signal level before entering the limiter. A variable saturation knob provides continuous morphing between the behavior of a classical limiter (zero softclipping) and a classical (soft)clipper (100% softclipping).
