Behaviors
- Select all audio, if selection required: If you select no audio before applying an effect, the effect will be automatically applied to all audio in all tracks.
This also applies to other menu items requiring an audio selection to be made, with the exception of and which are both deliberately restricted from this auto-selection to avoid accidental project deletion. Default setting for this is "off".
- Enable cut lines: Displays a red vertical line at the left edge of a cut edit. Click on the line at any time to restore the cut audio; if you restore in error, use to get the cut line back. To remove the line without restoring audio, right-click over it. will restore the line if you make a mistake. Default setting for this is "off".
See Preferences settings that affect Edit behavior for details of what this setting does.
A cut line is not created if one or both edges of the selection (before the Cut) touch the edge of a clip.
- Enable dragging selection edges: Lets you expand or contract existing selection regions with the mouse after they have been created. If unchecked you must use the Selection Bar or keyboard to modify existing selection regions. See Audacity Selection for further details. Default setting for this is "on".
- Editing a clip can move other clips: If the track has been split into more than one clip, any clips following to right of the edit point can always move as necessary in response to pasting, cutting, deleting or other change that adds or removes content.
Unchecking "Editing a clip can move..." pins clips so that they cannot move in response to an edit in another clip. When removing content, any following clips will not be allowed to move back. When pasting, an error message will display if there is not enough room to paste without moving the following clips. Default setting for this is "on".
See Preferences settings that affect Edit behavior for details of what this setting does.
Sync-Lock trumps (over-rides) this setting. If you have Sync-Lock enabled in the Tracks Menu, then clips can move even when this setting is turned "off". This works well when disabling/enabling Sync-Lock, as your preference for clips-can-move is not forgotten when out of Sync-Lock mode.
- "Move track focus" cycles repeatedly through tracks: When using the up and down arrow keys to change which track is focused, moving the focus off one end (top or bottom) makes the focus jump to the other end. Default setting for this is "off".
- Type to create a label: The default setting is "off", when enabled "on" if there is already a label track that has the yellow focus border, you do not need to use "Add Label at Selection" or its Ctrl + B shortcut to create a new label. Just type your required label text to create a new label at the position of the editing cursor or selection region. If the label track does not have focus, use the Up or Down arrow keys on your keyboard to move focus into the label track.
When this preference is disabled (default), typing never creates a label in the focused label track. This lets you use shortcuts (for example, transport shortcuts to play audio related to the editing cursor or selection) without accidentally creating an unwanted label. When you want to create a new label, use "Add Label at Selection" or Ctrl + B or "Add Label at Playback Position" Ctrl + M. Default setting for this is "off".
Even if "Type to Create a Label" is enabled, you cannot type to create a new label, if there is already a label at the exact same position in the label track.
- Use dialog for the name of new label: This is off by default, but when enabled creating a label will pop up a dialog box for you to enter the label name (rather than the default behavior of opening the new label itself for editing). When the dialog is closed, focus is returned to the track which was the focus before the dialog opened. This functionality is primarily provided to aid Visually Impaired users who use screen readers, but may be useful to normally sighted users too.
- Enable scrolling left of zero: Enables you to scroll to the left of time zero on the Timeline. The default setting is "off". This can make Scrubbing from the start or end of the track easier when using pinned play head.
If you select "Enable scrolling left of zero" then the negative numbers on the Timeline will be rendered in blue to act as a visual cue that this has been turned on. Default setting for this is "off".
- Advanced vertical zooming: When enabled, you can use left-click gestures in the Vertical Scale to make vertical zooms in audio tracks and note tracks. Default is "off", with such left-clicking disabled.
- Button: The button on the Track Control Panels can be set to behave in three different modes:
- "Simple" (default): "Solo" means as it does in common parlance - a track made solo is the only one that can be heard. If a track is solo, the mute buttons are set down on all the other tracks, so that solo is just a shortcut way of muting all tracks except one. If on any occasion you want the Solo button to select multiple tracks for listening, hold down Shift when clicking Solo.
- "Multi-track": this will suit those used to mixing desks and other professional audio software. Any number of tracks can be made "solo" (that is, active/live) so that they mix together, but if any Solo button is down, the mute buttons have no effect. If you want the Solo button to play only one track at a time (so that clicking it releases any other solo buttons), hold down Shift when clicking .
- "None": has no solo buttons, so you select the tracks you want to play or export by un-muting them (clicking the mute buttons so that they are up).
Please be aware that when using Export or Export Multiple Audacity will only export tracks that are not grayed-out by use of the or buttons in the tracks' Track Control Panels. So what you hear by previewing with playback prior to export is what you will get in the Exported audio file.
- When using Export Selected Audio, however, Audacity will Export the selection from all selected tracks even if some if those tracks are grayed-out and inaudible on playback.
