What LDC2 Compander does
The plugin models an analog optical compressor and expander, and the optical circuit can be exchanged among 17 real-time models. A fixed 4:1 ratio governs the compressor section, with maximum gain reduction of 40 dB, while the expander runs at a fixed 3:1 ratio with maximum gain reduction of 30 dB. Independent high-pass filters are provided on the side-chain gain of each section.
The signal path ends in a solid-state output stage fed by a diode-based preamplifier. The developer positions the plugin for tracking, mixing, mastering and live performances.
Key features
- Optical circuit models. Seventeen optical circuit models can be swapped in real time, changing the character of the gain reduction without reloading the plugin.
- Fixed-ratio expander. The expander section works at a fixed 3:1 ratio with up to 30 dB of gain reduction.
- Side-chain filters. Each section has its own side-chain gain high-pass filter, so low frequencies can be kept from driving the gain reduction.
- Diode preamplifier. A diode-based preamplifier feeds the processing stage ahead of the output.
Compatibility
The plugin ships as VST3, VST2, AU and AAX for Windows 7 and macOS 10.8 or higher, with native support for Apple Silicon listed. The developer lists 2 GB of RAM as the requirement.
