-- Every Region has a fade-in and fade-out. By default, the region fade - is very short, and serves to de-click the transitions at the start and - end of the region. By adjusting the regions fade length, a more - gradual transition can be accomplished. -
- -- Region fades are possible at the beginning and end of - all audio regions. In object mode, a grip appears at the top left and - top right of an audio region when the cursor hovers over it. Placing - the cursor over the top of the grip displays the region fade cursor - tip. Click and drag the grip left or right in the timeline to - adjust the length of the fade. -
- -- Crossfades refer to the behavior when you want to make - a smooth transition (mix) from one audio region to another on the same - track. Historically, this was done by splicing 2 pieces of analog - tape together, and this concept was carried forward into digital - editing. Each track is a sequence of sound files (regions). If - two regions are butted against each other, there needs to be a method - to splice them smoothly together. The crossfade allows one region - to fade smoothly out, while the next region fades smoothly in, like 2 - pieces of tape that have been cut at and angle, and overlapped. -
- -- But Ardour uses a more refined "layered" editing model, and - therefore it is possible for multiple regions to be stacked on a single - location with arbitrary overlaps between different layers. For - this reason, crossfades must be implemented differently. We can't - assume that a crossfade is an entitry that exists between 2 regions; - instead each region must have its own associated crossfades at each - end, and the topmost region must always crossfade down to the - underlying region(s), if any. -
- -- Ardour solves this problem by putting a crossfade at the beginning - and end of every region. The fades of the bottom-most region are - first rendered, and then each region is rendered on top of the one - below it, with fades at the end of each region providing a crossfade to - the region(s) beneath it. -
- -- It is important to understand that region fades are crossfades. When one region has - another region or multiple regions beneath its fade area, then you will - hear the topmost region fade-out be mirrored as a fade-in on the - underlying region(s). The grip for the topmost region will allow - changing the length and type of the crossfade into the underlying - region(s). In this way you can create a complicated series of - crossfades, and then layer another region atop the others, and fade - into that complicated series. -
-An image here would probably help.
- -- If a region doesn't have any region(s) under it, then the region is - crossfaded to silence; for convenience we call this a "fade" - rather than a crossfade. -
- -- To activate/deactivate or change the shape of a region's fade-in or - fade-out, hover the cursor over the region fade grip till the cursor tip - indicates region fade editing and context-click to bring up a context - menu. In the context menu there is a list of options for the - region fade. Activate/Deactivate enables and - disables the region fade. -
- -- Because each fade is also a crossfade, it has an inverse fade shape - for the audio beneath the fade. It is important to know how the - shapes differ, and which are most suitable for various editing tasks. -
- -- The different types of fades are: -
- -- Although these fade shapes serve specific purposes, any of the shapes is usable in certain situations. The final decision is an artistic choice rather than a rigidly prescribed one. -
- -- These fade curves are developed to provide a range of common uses, and - are developed with the least possible amount of changes in the "slope" - of the line. This provides artifact-free crossfades. Some - DAWs provide complicated fade editors with parametric "spline" controls - of the fade curves. While it might be interesting to develop a - fade curve with a faster cutoff, the mathematical difference between - this and simply shortening the fade is vanishingly small; the - amount of effort to shorten the fade is much easier than fooling around with a - crossfade editor dialog. -
