4. Audio Alignment

1>. Using the Tracks Menu

The menu commands in the Tracks > Align Tracks submenu provide an automatic way of aligning selected tracks with the cursor, the selection, or with the start of the project:

Align End to End:
  Aligns the selected tracks one after the other, based on their top-to-bottom order in the project window. The first selected track remains where it is, the start of the second selected track aligns with the end of the first selected track and so on.
Align Together:
 If you select multiple tracks, this command moves the tracks so that they all start at the same time, so audio within them changes its synchronization.
Start to Zero:
  Aligns the start of selected tracks with the start of the project.
Start to Cursor/Selection Start:
 Aligns the start of selected tracks with the current cursor position or with the start of the current selection.
Start to Selection End:
  Aligns the start of selected tracks with the end of the current selection.
End to Cursor/Selection Start:
  Aligns the end of selected tracks with the current cursor position or with the start of the current selection.
End to Selection End:
  Aligns the end of selected tracks with the end of the current selection.

2>. Time Shift Tool

An easy way for sighted users to align tracks with each other is to use the Time Shift Tool which is located, by default, at the top of the Audiotikal screen in the Tools Toolbar Tools Toolbar Timeshift tool.png

To use the Time Shift Tool, click on the button so it appears to be depressed, or press its shortcut F5. If you wish to change its shortcut to something other than F5, you can do so on the Keyboard tab of Preferences.

Then zoom in with Ctrl + 1 (or ⌘ + 1 on a Mac) so you can make a more precise alignment. Click in the track you want to move with the left button of the mouse, hold the button down while dragging the track to your required position, then release the mouse button.

There is no visual guesswork needed in aligning tracks as you can snap to track ends or labels when you time shift a track towards them. If you drag a selection region, the start point of the area on the time line is displayed dynamically, as a yellow vertical line, in the waveforms as you drag.

3>. Aligning tracks without a mouse - for visually impaired users

Visually impaired users can use this Time Shifter plug-in to time-shift tracks without a mouse. Instructions are given in Timeshif.TXT inside the zip folder.
This is one of a number of Nyquist plug-ins available for use in Audiotikal and works on both mono and stereo tracks.

4>. Marking alignment points

Some users find it easier to align tracks together when there is a vertical reference point extending down through all the tracks. You can make such a reference point by dragging the cursor down into the other tracks, and optionally by marking cursor positions with labels.

To drag the cursor into the other tracks, make sure you are using the Selection Tool IBeam.png (shortcut F1), and place your cursor at a point where you want to line up the tracks. Then hold down Shift on your keyboard and click in the Track Control Panels (where the mute/solo buttons are) of all your other tracks. Now you will see the cursor displayed in all the tracks, and you can switch to the Time Shift Tool and line up all the tracks against the cursor line.

To add a label at a cursor point, use Edit > Labels >Add Label at Selection. You can use the shortcut Ctrl + B (or ⌘ + B on a Mac) instead. The label is created in a new Label Track underneath the audio tracks. When you click on the label, all tracks will be selected and the cursor will be displayed through all the tracks, just like when you selected all the tracks by clicking on their Track Control Panels. However the label provides a permanent reference point you can come back to, and because you can have multiple labels in a Label Track, there can be multiple points you can line up with.
