Editing Concepts In Ardour, "editing" describes the process of making modifications to playlists. Recall that playlists are nothing more than lists of regions arranged over time. recording/modifying automation data

Snap Settings By default, when you move objects around, they move freely. There is a "granularity" to the motion, but it is a single audio frame (so typically on the order of 1/48000'th or 1/96000'th of a second), and at most zoom levels it will not be apparent in any way. However, this is not always the way you want to move some kinds of objects. If you are working with structured compositions that utilize traditional concepts of bars, beats, rythmn and so forth, you will often want to move regions so that that they always align to specific periodic time points that correspond to the start of a bar, or a beat etc. If you are working on a movie soundtrack, you may prefer to have regions always align to SMPTE frames, or perhaps even to whole seconds. Ardour provides a wide variety of "snap" settings. If any but "None" is selected, they define a grid of timepoints which will be used to "snap" object positions as they are dragged. The grid can be regular (as is the case if you choose "Beats", for example), or it can be completely irregular (if you choose "Marks", for example). It can even consist of a single timepoint (if you choose "Edit cursor", for example). Possible Snap Settings None no alignment used at all CD Frames align to 1/75th of a second intervals, as defined by the "Redbook" Audio CD standards SMPTE Frames align to whatever the current SMPTE frame interval is (defined in the options editor) SMPTE Seconds align to whole seconds, adjusted to account for any SMPTE start offset SMPTE Minutes align to whole minutes, adjust to account for any SMPTE start offset Seconds align to whole seconds Minutes align to whole minutes Beats/32 align to 1/32 divisions of the beat Beats/16 align to 1/16 divisions of the beat Beats/8 align to 1/8 divisions of the beat Beats/4 align to 1/4 divisions of the beat Beats/3 align to 1/3 divisions of the beat Beats align to beats Bars align to the start of bars Marks align to the nearest mark of some kind Edit Cursor align to the current position of the edit cursor Region starts align to the nearest start of a region in the (first) selected track Region ends align to the nearest end of a region in the (first) selected track Region syncs align to the nearest region sync point in the (first) selected track Region bounds align to the nearest region start or end in the (first) selected track
To change snap settings Move the mouse pointer to the toolbar panel of the editor window. Click on the "expansion arrow" of the "Snap setting" chooser. This will popup a list of available snap settings. If necessary, scroll down to see your desired choice. Click on your choice in the list to dismiss it and make Ardour switch to the new setting. Changing snap settings has no effect on the position of any existing region. Its effect is only on objects being moved. The snap setting also affects moving the playhead, the edit cursor, loop/punch and location markers, and dragging/moving range selections.
Snap Mode There are two subtly different ways in which the snap setting can affect region motion: normal snap mode regions can only be moved to positions defined by the snap setting. It is not possible to move them to intermediate positions. magnetic snap mode regions can still be moved to positions not defined by the setting, but they "stick" to the timepoints that are when dragged across them. Imagine that the timepoints and the regions are magnetic - or just try it and see. However, you can press the snap modifier key while dragging, and the snap setting will be ignored. By default, this is the key on your keyboard that generates Mod3 , but you can modify this from the Options Editor keyboard tab.
