editing/restoration tool. See The Spectrum display for more information on the unique

Spectrum display mode.

Rulers

There are both time and level rulers. These can be hidden and displayed (see the Ruler and

Wave Display context menus). You can also set which units of time and level they show. To

access the settings for both rulers, right-click anywhere on the relevant ruler.

Editing Tools

Precise editing of your audio is achieved in the main (lower) waveform window. There are

three main tools that are used for directly editing an Audio File:

Time Selection cursor - This is the default cursor and allows you to select and resize

regions of audio you wish to edit. Click and drag in the main waveform window to make a

selection. You can modify the selected region by click-dragging on the edges of the selection.

You can also modify a selected audio region by holding down [Shift] and clicking on the

waveform. The selection extends/shrinks to the clicked point. If you hold the cursor over one

channel of a stereo ﬁle you can make selections in that individual channel. You can double-

click inside a region to select it then drag the mouse to select the next or previous regions,

that is, you snap to markers while dragging.

Spectrum Selection cursor - this cursor allows you to select and deﬁne regions when

in the Spectrum view. See Spectrum editor for more information on making selections and

using the Spectrum view for advanced editing purposes. Pen tool - this tool allows

you to redraw the waveform directly in the wave window. It can be used to quickly repair

waveform errors by hand. The Pen tool can only be used if the Zoom resolution is set to at

least 1:8 (one pixel on the screen equals 8 samples) or higher. If you wish to redraw the

waveform of both channels in a stereo ﬁle at once, press [Shift] while drawing.

Once you have deﬁned an audio selection there are many editing tools available in the Edit

menu of the Audio File Workspace for you to explore. These range from basic editing com-

mands such as Copy and Paste to special functions which can perform tasks such as trim-

ming, muting, crossfading, appending, prepending, silencing and repeating an audio selec-

tion, for example. It is well worth exploring the tools available in this menu.

There a number of options available that affect editing in the waveform window. See Audio

File editing preferences for more information on the various preferences available.

Editing Shortcuts

You can navigate through your Audio File by dragging the Time Selection cursor. Alternatively

you can use the following keyboard shortcuts:

Use the [Left Arrow] and [Right Arrow] to move the cursor one pixel in either direction.

Use [Ctrl]/[Command] + [Left Arrow] and [Right Arrow] to move the cursor twenty

pixels in either direction. You can also use the [Page up] and [Page Down] keys.

Use the [Home] and [End] keys to navigate to the beginning and end of the wave.

You can also scroll and zoom within the Audio File Workspace using several other mouse

and keyboard shortcuts. See Zooming and scrolling for more detailed information.
