Selection in the menu.

Use the Selection submenu to change the or moving the start and finish markers.

Use Set to change the 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 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 for many more ways of setting the selection.

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).

Use Move Start To Elapsed and Move Finish To Elapsed to move the 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.

Use Move Start To Beginning to move the 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.

Use Move Finish To Start to move the 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 in the submenu.

Use Recall Selection Range to set the to the range previously stored using . Hold the Ctrl key to recall a range stored within a different .

Store Selection Range in the submenu.

Use Save Selection Range to save the current range. Use reset the range to the stored range. Hold the Ctrl key to store the range so they can be recalled in a different .

Snap To Zero-Crossing in the 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 menu to limit the snap feature to a single channel or use the "Sharp faded ends" preset in 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 ), the snap feature is automatically turned off so that markers can be placed at any position.
