Using fades and crossfades in real-time

You can create real-time fades and crossfades in the Track view’s Clips pane. Real-time fades and crossfades do not change the data in the clip. Sonar reads the fade-in, fade-out, or crossfade in the clip and adjusts the gain accordingly. You can edit the crossfade’s start time and end times. You can set the type of fade-in or fade-out you want to use as a default:

Linear. A straight line, raising or lowering the volume at a steady rate.

Slow Curve. A curved fade which starts to change the volume slowly at first and then rapidly increasing (fade-in) or decreasing (fade-out) the volume.

Fast Curve. A curved fade which starts to change the volume quickly at first and then rapidly decreasing (fade-out) or increasing (fade-in) the volume.

To choose the fade type

Click the Track view Options menu, point to Crossfade Type and select the desired default Fade-In, Fade-Out and Crossfade curve types.

To create a real-time fade-in in a Clip

1.	Select the Smart tool or Edit tool in the Control Bar.

2.	In the Track view’s Clips pane, move your mouse over the top part of the beginning of a clip until the cursor looks like this: , and a red line appears at the edge of the clip.

A filled red triangle appears at the top of the red line indicating the fade marker is ready to be dragged.

A. Filled red triangle

3.	When your cursor changes and the filled red triangle appears, click and drag to the right until you reach your desired fade-in length.

As you drag your mouse, a fade-in appears on your clip, and the red line moves with the mouse to mark the end of the fade-in.

To edit a fade-in in a Clip

To move the entire fade-in to a later point in the clip, drag above the blue horizontal line located a quarter of the way up the blue vertical line

.

A. Cursor above horizontal blue line B. Horizontal blue line

To move only the starting point of the fade-in, drag below the horizontal blue line.

To delete a fade-in from an audio clip, simply drag the triangular fade handle to the front edge of the clip.

The filled blue triangle at the top of the clip handle indicates that dragging the top edge of the clip handle will move the fade along with the crop. The filled blue rectangle at the bottom of the clip handle indicates that dragging the bottom of the clip handle will slip edit the edge, but leave the end of the fade-in where it is.

To create an automatic crossfade (real-time)

1.	Click the Track view Options menu and choose Auto Crossfade.

2.	Click the Track view Options menu, point to Crossfade Type > Default Crossfade Curves and select the desired default crossfade curve types.

3.	Select and drag an audio clip so that it overlaps another audio clip. You should overlap the clips by the length you want the crossfade.

4.	When you have the clip positioned where you want it, release the mouse button to drop the clip.

The Drag and Drop Options dialog box appears.

5.	In the Drag and Drop Options dialog box, select the Blend Old With New check box and click OK.

6.	The two clips now overlap with a crossfade, looking something like this:

A. First clip B. Fade-out C. Fade-in D. Second clip E. Crossfade

You can edit fade-ins and fade-outs. You can change the start, end and position of a fade. The following procedures all demonstrate edits to a fade-in, but fade-outs work exactly the same.
