SignatureDYN - Compressor / Gate / Limiter SignatureDYN is a professional 3-in-1 dynamics processor for iPhone and iPad. It combines a peak compressor, a smooth noise gate, and a brick-wall limiter in a single AUv3 plugin - covering the complete dynamics processing chain in one insert slot. Compressor Hard-knee peak compressor with independent attack and release. Threshold from −60 to 0 dB, ratio from 1:1 to 20:1. Transparent at low ratios, aggressive at high ratios. Gate Exponential noise gate with smooth closing - 3× slower than opening to avoid clicks and unnatural cutoffs. A dedicated LED indicator lights when the gate is active, making threshold setting precise and visual. Limiter Brick-wall output limiter with fixed 0.1 ms attack. No signal exceeds the set ceiling. Release follows the compressor release time. Default ceiling −0.3 dB — transparent protection always on. Metering Real-time Input VU meter and Gain Reduction meter with dB scale. Signal presence LED.
