What SSL Fusion HF Compressor does
The plugin emulates high-frequency smoothing with a modelled SSL Fusion HF Compressor processor. Its compression acts only on frequencies above the crossover, which gives a distinctive high-frequency rounding and a tape-like roll-off. A simple threshold and crossover pair sets the basic behaviour, while ratio, attack and release are optimised under the hood for maximum transparency.
The design draws on a combination of real-life measurements, analogue circuit designs and close collaboration with the original analogue circuit designers. A MIX control blends the processed and unprocessed signal to dial in the amount of smoothing, and an AUTO GAIN control applies automatic make-up gain at high frequencies. Presets from producers and engineers Adrian Hall, Caesar Edmunds and Sean Divine are included.
Key features
- Gain Reduction History and meter. A Gain Reduction History graph and a Gain Reduction meter show how the effect is working over time, and a circuit activity LED from the original hardware indicates when the circuit is compressing.
- LISTEN solo mode. LISTEN solos the frequencies being compressed, so the sibilant or harsh content removed from the signal can be heard directly.
- ECO mode. ECO mode reduces latency and CPU use, intended for tracking and recording sessions.
- Built-in help. Clicking the question mark symbol at the bottom right and then hovering over the interface shows a description of each control.
- Use across sources. The compressor can be used on individual tracks, such as vocals, electric guitars and drum tracks, as well as on a full mix.
Use cases
- Cymbals and drum tracks. Cymbals and drum tracks are tamed by rounding brittle high frequencies with the MIX control blended in.
Compatibility
The plugin is built for VST3, VST2, AU and AAX on Windows 10 and macOS 11 in 64-bit builds, with native support for Apple Silicon listed. It uses iLok for copy protection and lists 4 GB of RAM.
