Aquamarine4 is a premium mastering and mixing plugin suite designed to enhance a wide range of musical genres. Its comprehensive set of tools delivers professional-grade sound shaping, enabling producers and engineers to achieve polished mixes with ease. The plugin is built to offer both subtle and impactful dynamic control, making it suitable for diverse production needs.

At the core of Aquamarine4 is a powerful compressor inspired by one of the industry's most respected and costly hardware units. This compressor combines a smooth, warm opto compression section with a punchy, discrete VCA-style processor. Users can adjust the compression ratio from a gentle dynamic massage starting at 1.2:1 up to aggressive limiting modes, allowing for precise control over the dynamic range and creative compression effects.

Aquamarine4 also includes a highly accurate emulation of a rare American passive equalizer from the 1950s, bringing vintage tonal characteristics to modern productions. This feature enriches the sound with classic warmth and character, providing an authentic analog vibe that can enhance any mix or master. The plugin suite combines historical sonic qualities with contemporary functionality for a comprehensive audio processing experience.
