Fading In and Out

A fade-in can be done using a combination of Volume envelopes and slowly adding instruments (tracks) one at a time. Although you could simply add Volume envelopes over the existing beginning of a song (before you create a dedicated introductory section), you will still lose the first verse or refrain, so it is still probably a good idea to insert time and create a dedicated introduction.

Vasily had no idea how far they walked, he and the girl. The streets jumped by in dizzying snapshots as his consciousness faded in and out. But at a quiet street corner a van pulled up and a man he d never met gestured him to the rear where he climbed in, joined the other men and women on board and took possession of a Kalashnikov assault rifle. 

Envelopes overlay events in a track, controlling the volume and paiming aspects in real time. Envelopes allow you to fade in and out of a loop or pan across stereo channels. For example, a red volume envelope that starts at the bottom of a track and moves up towards the center indicates a volume that gradually increases over time or fades in (see Figure 1.9). While envelopes are technically track-level objects, they operate on events and typically correspond to specific events in a track. For this reason, envelopes can be locked to events (they move as the events move) by making sure the Lock Envelopes to Events button is depressed. 

To experience a Rothko, you need to slow down and change your perspective, moving back, forth, in, and out. Only then do you see the many layers of colors and washes, the texture of the brushstrokes, the interface where a rectangle fades into the background. The color speaks as you move. 

Volume and Pan envelopes (as well as FX envelopes) are track-level envelopes— that is, they run across an entire track, affecting every event in that track. Individual events can also be quickly faded in or out using event fade envelopes, otherwise known as Attack-Sustain-Release (ASR) envelopes. To create an event fade, move the mouse cursor over the upper (left or right) corner of an event. The cursor changes to the special event fade cursor (see Figure 4.4). Drag the fade envelope in towards the center of the event. 

Drag the middle of the line (at the center of the four points) down to reduce the gain. The shorter segments between point one and two and between three and four serve as a brief fade-in and fade-out. These can be very short, often less than half a second. 

The research published in this book uses the presently most comprehensive multicompartment model, the first which comprises a coupled atmosphere-ocean general circulation model (GCM). GCMs are the state-of-the-art tools used in climate research. The study is on the marine and total environmental distribution and fate of two chemicals, an obsolete pesticide (DDT) and an emerging contaminant (perflu-orinated compound) and contains the first description of a whole historic cycle of an anthropogenic substance, i.e. from the introduction into the environment until its fading beyond phase-out.
