The ACM-3SA is a precision filter plugin inspired by the classic Pultec HLF-3C passive filter, designed to deliver smooth and natural sound shaping. It offers 12dB per octave low-cut and high-cut filters that effectively remove unwanted rumble, hiss, and hum while preserving the integrity of your audio content. With its carefully crafted processing, the plugin provides an authentic analogue-style frequency response that enhances your mix without introducing artifacts.

Featuring an intuitive, stylized user interface, the ACM-3SA ensures easy navigation and control during your sound sculpting process. The rotary controls are physically modeled for a realistic tactile feel, and the interface can be resized to fit your workflow preferences. Switching between filter settings is smooth and seamless, allowing for efficient adjustments without interrupting creative flow.

Optimized for performance, the ACM-3SA operates with minimal CPU usage and zero additional latency, even at lower sample rates. It supports multiple plugin formats including VST, VST3, AAX, and CLAP, and is compatible with both Windows and Linux systems. This combination of high-quality processing and broad compatibility makes the ACM-3SA an essential tool for precise and transparent filtering in any production environment.
