Selection Menu
Selection in the Edit menu.
Use the Selection submenu to change the selection or moving the start and finish markers.
Set
- Set in the Edit | Selection submenu.
- Set button in the Toolbar.
- Set Markers/Selection edit command in the Add Edit window of Batch Processing.
Use Set to change the selection range by setting start and finish markers to an exact time or sample position. To specify a time, choose the Time based range option and enter the times in hours, minutes, seconds, and thousandths of a second. Enter 1:23:45.678, for example. To specify a sample position, choose the Sample based range option and enter the positions. Tip: Right click on one of the up/down controls to change the precision of the controls.
To align the length of the selection to a CD sector or 1 kilobyte, select the appropriate option. The finish marker will be adjusted to align length when OK is pressed.
See Editing Overview for many more ways of setting the selection.
Previous
- Prev in the Edit | Selection submenu.
- Set button in the Toolbar.
- Set Markers/Selection edit command in the Add Edit window of Batch Processing.
Use Previous to set the selection to its previous range. The last five selection ranges are stored automatically whenever the selection is changed. Using this command repeatedly sets the selection back to each of those five ranges. Note that absolute positions are stored, so any modifications, such as deleting part of the sound, will not be factored into the previous positions. In such situations the previous positions may not select the same part of the sound that was previously selected (that part may have been deleted).
Move Start/Finish To Elapsed
- Move Start To Elapsed in the Edit | Selection submenu.
- Move Finish To Elapsed in the Edit | Selection submenu.
Use Move Start To Elapsed and Move Finish To Elapsed to move the start or finish marker at the current playback or recording position. Use the bracket keys, [ and ] to move the start and finish markers respectively. If the start marker is moved past the finish marker, the finish marker is moved to the end of the file. If the finish marker is moved ahead of the start marker, then the start marker is moved to the beginning of the file.
Move Start To Beginning/Finish
- Move Start To Beginning in the Edit | Selection submenu.
- Move Start To Finish in the Edit | Selection submenu.
Use Move Start To Beginning to move the start marker to the beginning of the file. Use Move Start To Finish to move it to the finish marker's position. This sets the selection to nothing.
Move Finish To Start/End
- Move Finish To Start in the Edit | Selection submenu.
- Move Finish To End in the Edit | Selection submenu.
Use Move Finish To Start to move the finish marker to the start marker's position. This sets the selection to nothing. Use Move Finish To End to move it to the end of the file.
Recall Selection Range
Recall Selection Range in the Edit | Selection submenu.Use Recall Selection Range to set the selection to the range previously stored using Store Selection Range. Hold the Ctrl key to recall a range stored within a different Sound window.
Store Selection Positions
Store Selection Range in the Edit | Selection submenu.Use Save Selection Range to save the current selection range. Use Recall Selection Positions reset the range to the stored range. Hold the Ctrl key to store the range so they can be recalled in a different Sound window.
Snap To Zero-Crossing
Snap To Zero-Crossing in the Edit | Selection submenu.Turn on Snap To Zero-Crossing to reduce pops and clicks caused between edit points. When editing, it is important that the waveform not change suddenly from one amplitude to the next, otherwise a click will occur. This can happen when deleting the selection. The amplitude of the waveform at the start marker may be completely different from the amplitude at finish marker. After deleting the selection, these two different amplitude will be adjacent, causing a click.
Snap To Zero-Crossing helps minimize the problem by ensuring that the markers are always near zero amplitude samples. When you drag and release a marker, it is automatically moved to a position where the amplitude approaches zero. This means that when you delete the selection, the amplitudes at both the start and finish markers will be more closely matched (near zero).
Since stereo and multichannels sounds can have very different channel amplitudes, finding an ideal zero-crossing position may not be possible. Use the Edit | Channel menu to limit the snap feature to a single channel or use the "Sharp faded ends" preset in Shape Volume to force the ends of the selection to have zero amplitude (the unselected ends will have to be faded when deleting the selection).
If the zoom level is close enough that the true shape of the waveform is shown (such as Zoom 1:1), the snap feature is automatically turned off so that markers can be placed at any position.
