Since Envolution is an adaptive process that constantly changes with programme content, the peak limiting function will not be as predictable and accurate as that provided by a programme limiter. Coupled with an appropriate Transient Sensitivity setting transients can be reduced by the required amount, allowing the overall level of the programme to be increased before limiting occurs. To achieve this effectively, small negative Transient Level and Transient Release values should be used with the minimum Transient Attack setting, in order to catch the fastest transients only. Since the look-ahead process timing can act on the signal before it appears at the output of the plug-in, short-term peaks can be effectively reduced without apparent loss of overall sonic character. If very short-term peaks are reduced, higher modulation levels can be achieved without overloads. In many cases, very short transients may not be a prominent part of the programme sound, and can be reduced without damaging the sonic character of the results. When used with negative Transient Level settings, Envolution can provide a useful method to increase the loudness of programme by reducing very short transients that may otherwise cause overloads. Warmth processing will also change the harmonic content of the programme to provide warmth and richness to many programme types. When set to maximum ( 100%) the Warmth process will allow peak input signals up to +6dBFS to be included without the sound of hard clipping, while preventing output signal overloads greater than 0 dBFS. The Warmth process is included to allow a degree of relief from premature clipping if high modulation levels are required, by providing a method for the harmonic content of peak information above digital max to be included in the final output signal from the plug-in. Therefore care must be taken to set appropriate Output Gain settings to prevent levels over 0 dBFS. Since most DAW applications provide no headroom above the peak level operating target that most users aim for, the increased signal level is susceptible to overloading processing after the Envolution plug-in. This effect will be seen on the plug-in's Output Meters as well as on the Transient and Sustain Effect meters. The Sustain process can dramatically change average signal levels, and can also increase the peak level of the input programme. With highly percussive sounds, the peak levels can increase by up to 24 dB. Warmth and Level ControlДЄlthough the Transient process works to maintain constant average signal levels, the process can produce significantly larger peak levels when positive Level settings are used. Tweak the balance of sustain enhancement to prevent excessive low-mid build-up. High frequency ambience will be reduced by a smaller amount, allowing the cymbal decay to pass through unaffected! To resolve this, simply use Tilt Mode to reduce the Freq Mix Amount at high frequencies. For example, when using the Sustain section to reduce room ambience on a drum bus, the cymbals may begin to sound unnaturally 'gated'.

If you're ever hearing too much effect in the Low or High regions, use Tilt Amount to tilt the curve down in that region. At extreme settings (-100% and 100%), the response changes to a low-pass or high-pass filter, allowing you to exclude low or high frequency signal components from the processing. Defaulting to a smooth 6 dB/octave slope, this is very useful for gentle tone shaping. Tilt Mode provides 'tilt EQ' style control of frequency dependency. With 0% Tilt/Focus settings, Envolution is frequency-independent and completely true to the spectrum of the input programme, unlike a multi-band processor. There are no FIR filters either, which allows the plug-in to have very low latency. Because of this, inserting the Envolution plug-in into parallel routing paths will not introduce static phase-cancellation artefacts.

An important aspect of this behaviour is that it is achieved without splitting the signal into multiple frequency bands.

These controls make the detection and application of the Transient and Sustain effects frequency dependent.

This can be thought of as a frequency dependent wet/dry mix вЂ“ the top of the graph is fully Wet, the bottom is Dry.
