Amethyst by Acustica Audio is a powerful channel-strip bundle designed to deliver professional audio processing with precision and character. This bundle includes a complete channel strip plug-in along with dedicated EQ, preamp, and compressor plug-ins, each crafted to provide detailed control over sound shaping. The latest version, Amethyst3, integrates support for the CORE X audio engine, introducing advanced features such as a new hard-clipping algorithm that allows for a maximum level increase of +3 dBFS, a multi-input system, and an innovative blending algorithm to enhance audio quality and flexibility.

The EQ sections offer extensive frequency control with multiple bands covering low, mid, and high ranges, featuring adjustable gain, Q control, and switchable shelving options to tailor the tonal balance. Complementing the EQ, the preamp section emulates classic hardware models, providing warm and rich tonal coloration. The compressor module delivers versatile dynamics processing with adjustable threshold, ratio, attack, release, and make-up gain, along with features like hard knee and side-chain support to handle complex mixing tasks effectively. Together, these components create a comprehensive channel strip capable of enhancing various audio sources with clarity and depth.

Amethyst supports major operating systems including macOS and Windows and is compatible with VST2, AAX, and AU plug-in formats available in both 32 and 64-bit architectures. The licensing system allows activation on two computers per license, with a free four-week trial version available for users to evaluate its capabilities. Developed using Acustica Audio’s proprietary sampling technology, Amethyst captures the nuanced behavior of vintage and high-end hardware processors, providing an authentic and dynamic sound that adapts to user input and settings. This makes it an essential tool for producers and engineers seeking high-fidelity channel strip processing.
