In VoceVista Video, the concept of a selection extends to a time range of the recording, and to elements that can be selected individually, such as piano keys and note sliders:

Using keyboard modifiers (Control / Command)

To change the selection with the mouse, you need to hold the Control key (on Windows), or the Command key (on Mac).

On the Selection Settings page, you can set the Mouse Click Action to change the selection with the simple click instead of requiring the Ctrl/Cmd key. This is the behavior used by Overtone Analyzer 4.

Selecting time range of a recording

Parts of the recording can be selected on the Timeline, the Waveform View, and on the Spectrogram. Simply click anywhere on these views, hold the left mouse button, and move the mouse to the end of the area that you want to select. The selected area will be marked with a different background color. You can click and drag the borders of an existing selection to make it longer or shorter.

Working with a time selection

Once you have selected a time range, you can press the Play button to play it repeatedly. You can choose if playback should be repeated automatically by clicking on ToolsLoop playback.

You can also click on ViewZoom to fit selection to set the visible time range to match the current selection.

Conversely, you can click on EditSelect visible range to select the time range that is currently visible.

Use the command EditSet selection to enter precise numbers for the time range to be selected.

Further, you can apply edit commands such as Cut, Copy, Paste, etc. to the current selection.

Locking a selection

If you click anywhere on the Timeline or the Spectrogram, the playback cursor will jump to the position of the click, and the current selection will be reset. Sometimes you might want to keep the selection a bit longer, but still move the cursor within the selection to hear specific parts. To prevent the selection from being lost when you move the cursor, click on EditLock selection. Now the selection can still be resized by moving its borders, but clicking somewhere on the Timeline or Analyzer View won’t destroy the existing selection. This is particularly useful when comparing files, and when working with Frequency Filters.

Resetting the selection

If the selection is not locked, you can simply click on the Timeline or Analyzer View to remove it. This will reposition the playback cursor and reset the selection. You can also clear the selection by clicking on EditReset selection, or by pressing the ESC key.

Selecting Tones

You can select and deselect tones on the piano keyboard and on the Overtone Sliders by clicking on them while holding the Control key (on Windows), or the Command key (on Mac). To play those tones, click on SlidersPlay selected tones or press the Return key.
