4.Continue holding the left mouse button while clicking the right mouse button. The mouse icon and the appearance of the selection region change to indicate the current drag-and-drop mode.

5.Release the left mouse button. The source audio data is pasted, mixed, or inserted as a CD track.

Creating new windows by dragging and dropping a selection

Drag-and-drop also allows you to create a new data window from a selection.

1.Open the Voiceover.pca file.

2.Create a selection containing “Wow.”

3.Drag the selection to an empty area of the Sound Forge workspace and drop it. A new data window is created containing the selection data with the attributes of the original file.

Tip: When dragging a selection to paste sound data, drag up or down before moving the mouse left or right. Dragging left or right before moving the mouse vertically adjusts the selection length.

Finding and repairing audio glitches

Glitches are commonly the result of analog audio editing, analog to digital transfer, or electronic noise. Sound Forge software provides you with a tool for locating audio glitches and three distinct tools for repairing them: channel, interpolate, and replace. In addition, you can repair audio glitches manually using the Pencil tool.

Locating glitches

The Find tool allows you to quickly locate glitches, specific volume levels, or silence in a file. The Find tool’s glitch algorithm locates glitches by examining the file for instances where the waveform matches the specified threshold slope and sensitivity criteria. The cursor then moves to the location of the glitch to allow you to repair it. This tool locates only one glitch at a time. Therefore, it may be necessary to execute this command several times on a file to locate all glitches.

1.Open any audio file containing glitches.

2.From the Tools menu, choose Find. The Find dialog is displayed.

3.From the Find drop-down list, choose Glitch.

4.Adjust the Threshold slope fader to configure the minimum slope that constitutes a glitch.

•A high value detects only glitches with steep slopes.

•A lower value detects glitches with both steep and more gradual slopes.

5.Adjust the Sensitivity fader to determine the sensitivity of the detection algorithm.

•A high value results in any part of the waveform with a slope greater than the Threshold slope being detected as a glitch.

•A lower value forces the algorithm to verify that the slope is indeed a glitch, and not simply a portion of the smooth waveform.
