Ardour's editor utilizes a <dfn>grid</dfn> to assist in the placement of regions
on the timeline, or with editing functions that need to happen at a specific
point in time. This <dfn>snapping</dfn> of the cursor and various objects to the
grid can be toggled on or off, as does its behaviour, and grid units.

<h2> What is “Snap” and “Grid”?</h2>
“Snap” will cause drags and other mouse-driven operations to jump to
positions determined by the nearest snap setting. Snap can be set to
multiple options: markers, region start/ends, and the grid. ( those
are all enabled by default. change them in prefs )
Grid can be enabled, and it will draw lines at selected intervals;
which can be musical, like 16th notes, or can be timecode based
(minutes and seconds) . You can leave the Grid enabled, but snap
disabled, if you just want to see the lines but not snap to them.
For example: if the Grid is set to “beats” and Snap-to-grid is
enabled, then any operations such as split, paste, or range-select
will happen exactly on a beat, according to the musical timeline and
tempo.
Alternatively, you can leave “Snap” enabled (so your mouse actions
can snap to Markers, or region edges) but disable the Grid.
<h2>About Snapping</h2>
<p>
There are two ways to think about aligning material to a grid. The first and
most obvious one is where an object's position is clamped to grid lines. In
Ardour, this is called <dfn>absolute snap</dfn> and is commonly used when
working with sampled material where audio begins exactly at the beginning of a
file, note or region.

The second, <dfn>relative snap</dfn>, is used when an object's position relative
to the grid lines is important. In music, this allows to move objects around
without changing the "feel" (or timing) of a performance.

<h2>A Warning, of sorts</h2>
<p class="warning">
The grid consist of lines running vertically in the edit canvas. If
you zoom too far out, you might see a coarser grid than you
expect. Ardour tries not to show “too many” or “too few” grid lines
depending on the zoom level. You might find that items snap in-between
the grid lines sometimes. Thats expected behavior. If you cant see
or snap to the grid youd like to use, you may have to zoom in or out.
