1 Overview

1 OVERVIEW

The Oxford Envolution plug-in provides comprehensive control over the transient and

sustain portions of an audio signal. Unlike most alternatives, attack, hold and release

can be independently adjusted, enabling a wide variety of effects.

In addition to this, the effect of the transient and sustain processing may optionally be

applied in a flexible frequency dependent manner. This is achieved without splitting the

signal into separate bands, so unlike conventional multi-band processors, Oxford

Envolution may be freely used in parallel routing configurations without creating

phase-cancellation problems.

2 THE MAIN LEVEL CONTROLS

2 TheMainLevelControls

To enhance or reduce the Transient or Sustain portions of the input signal, simply

increase or decrease the main level control.

Gain is set in dBs and will not exceed the selected setting, regardless of the Profile

settings. The current level of the gain envelope is displayed in the circular meter inside

each level control.

The centre panel can be assigned to three views. Use the left-hand buttons to assign the

panel to a different view.

4 ENVELOPE SCOPE

4 EnvelopeScope

The Scope display shows an amplitude over time trace for the input signal (grey),

Transient envelope (yellow), and Sustain envelope (purple).

By default, the scope operates in Scroll Mode, in which the time axis scrolls freely from

right to left.

When using Envolution in a tempo-mapped project, the Bar Sync modes are more

appropriate. To select a different mode, click the settings panel which appears with the

mouse cursor over the Scope display.

Particularly in Scroll mode, it may be useful to freeze scope display in order to inspect the

shape of the envelopes. To do this, just click anywhere inside the Scope display. When

frozen, a blue border is drawn around the display. Click again to unfreeze.

Transient Profile Controls

For high-quality and versatile detection and processing, all time constants are

automatically adjusted based on characteristics of the input signal. Because of this, the

timing profile parameters are shown as a percentage of the available range.

While the Attack, Hold and Release controls perform similar functions for both the

Transient and Sustain sections, their behaviour in use is quite different. These differences

are outlined in the following sections.

The Scope display in the centre panel of the plug-in helps to visualize the sensitivity and

shape of the gain envelopes which are applied to the signal.

5.1 Transients

5.1.1 Attack

This can be used to smooth the leading edge of the transient envelope over time. Slower

attack times allow some of the initial edge of the detected transient event to pass through
