Exploring Acustica Audio’s Amber 4 Ultra Plug-In Suite: A Comprehensive Review and Overview

  • by

You have reached the page for the Amber 4 Ultra plug-in suite created by Acustica Audio.

The newest release from Acustica Audio incorporates their advanced Hyper technology and updated Aria engine to offer an improved version of their well-known Amber 4 plug-in collection. Amber 4 Ultra features accurate emulations of Class A equipment such as EQs, a compressor, and preamp, all with upgraded visuals and enhanced audio quality.

The suite includes two EQ plug-ins called Amber 4 Ultra and Amber 4 Stereo Ultra. Each plug-in has the same controls, but the Stereo version has separate controls for each channel. Both plug-ins have four bands with frequency and gain controls. The low- and high-mid bands have a width parameter, while the low- and high-frequency bands have a control to switch between peak and shelf filter types.

Amber 4 Ultra includes a continuous control feature that allows users to adjust mid, left/right, and side signals. On the other hand, Amber4 Stereo Ultra offers separate control over the left/mid and right/side channels. Acustica claims that the former is a highly effective parametric EQ with minimal noise in the digital realm, while the latter is one of the most sonically transparent EQ choices in their lineup.

The Amber 4 Comp Ultra emulates a Class-A opto compressor unit using Hyper technology to provide a clear dynamics processor. It includes standard compressor controls as well as extra features like side-chain filtering, stereo linking options, a blend control for mid, left/right, and side signals, and built-in parallel compression.

The Amber 4 Pre Ultra offers a variety of Class A preamp designs, featuring both solid-state and valve-based units. Each unit has a basic set of controls including input and output levels, Preamp (gain), and Filter (high-pass).

The plug-ins now have support for dynamic and real-time metering displays thanks to the new Aira engine. They also feature the company's Anti-Aliasing algorithm and have lower CPU usage compared to the previous versions.

System Requirements

Amber 4 Ultra is compatible with computers running Windows 10 or 11, and Apple computers running macOS 10.15 and above. Users can access VST2, VST3, AU, and AAX plug-in versions.

The Amber 4 Ultra product is currently on the market and can be purchased at a discounted price of €89 until February 26, 2024. After this date, the price will increase to €209.
