Extreme Dynamics

Extreme Dynamics is a versatile single band compressor/expander device, which offers a wide range of control options and monitoring capabilities. It features 5 different dynamic response functions operating both above and below the threshold level, look-ahead and peak modes, several attack/release envelope filter tuning options, a saturation effect, oversampled signal processing, a multi-mode segmented meter display and a scope display to view the actual dynamic response curves on a graph. If you like experimenting with compressors and especially visualizing what you are doing, this is the tool for you.

What this device features:

• 3 compressor and 2 expander response curves, which can be applied both above and below the threshold and combined in any possible way. It can perfectly emulate all the built-in Reason compressors (except for auto-release mode) and most of the others (not involving hardware emulations). You can also set it up to something totally unique to suit your needs.
• Upward compression (below threshold). It can bring near silent (-120dB) signals back to audible range.
• Look-ahead delay mode. The input signal is delayed before the gain changes are applied to it. It is automatically delay compensated if used together with the DAW PDC.
• Peak mode. That also allows for gradual shift between peak (instant) and traditional (averaging) follower.
• True RMS follower mode.
• Soft-knee (smooth) segment around the threshold point.
• Segmented meter display, which can show 3 different signals: the applied gain, the input (or sidechain) level relative to the threshold, and the output level.
• Scope display to watch the actual response curve that you get with the parameters you have set, and to monitor the signal response on the same graph.
• Export/import of the raw gain control signal as a CV or as an audio signal (with full sample rate resolution).
• Controllable saturation effect (harmonic distortion) driven by dynamics gain.
• Up to 8x oversampling and ultrasonic filtering to suppress aliasing and intermodulation.

What this device does not do:

• It does not limit the output signal. You may (accidentally) set it up to overdrive the output by +120 dB. Protect your ears and equipment.
• It does not have a Dry/Wet control or internal LP/HP filters. If you want a parallel compression or pre-filtering, you will need to arrange it yourself.
