This includes fixing em-dashes, badly spaced colons, various
misspellings, removal of spurious {% %} constructs, conversion of <br />
to <br> (still too many <br>s kicking around), and initial light cleanup
of a few sections that caught my eye.

<h2>Working With Regions</h2>
|
|
|
|
<p>
|
|
<dfn>Regions</dfn> are the basic elements of editing and composing in Ardour. In most cases, a region represents a single contiguous section of one or more media files. Regions are defined by a fixed set of attributes:
|
|
</p>
|
|
|
|
<ul>
|
|
<li>the audio or <abbr title="Musical Instrument Digital Interface">MIDI</abbr> <dfn>source file(s)</dfn> they represent,</li>
|
|
<li>an <dfn>offset</dfn> (the "start point") in the audio or MIDI file(s), and</li>
|
|
<li>a <dfn>length</dfn>.</li>
|
|
</ul>
|
|
|
|
<p>
|
|
When placed into a playlist, they gain additional attributes:
|
|
</p>
|
|
|
|
<ul>
|
|
<li>a <dfn>position</dfn> along the timeline, and</li>
|
|
<li>a <dfn>layer</dfn>.</li>
|
|
</ul>
|
|
|
|
<p>
|
|
There are other attributes as well, but they do not <em>define</em> the region. Things you should know about regions:

<h3>Regions Are Cheap</h3>
|
|
|
|
<p>
|
|
By themselves, regions consume very little of your computer's resources. Each region requires a small amount of memory, and represents a rather small amount of CPU work if placed into an active track. So, don't worry about creating regions whenever you need to.

<h3>Regions Are Not Files</h3>
|
|
|
|
<p>
|
|
Although a region can represent an entire audio file, they are never equivalent to an audio file. Most regions represent just parts of an audio file(s) on disk, and removing a region from a track has nothing to do with removing the audio file(s) from the disk (the <kbd class="menu">Destroy</kbd> operation, one of Ardour's few destructive operations, can affect this). Changing the length of a region has no effect on the audio file(s) on disk. Splitting and copying regions does not alter the audio file in anyway, nor does it create new audio files (only <dfn>recording</dfn>, and the <kbd class="menu">Export</kbd>, <kbd class="menu">Bounce</kbd> and <kbd class="menu">Reverse</kbd> operations create new audio files).
