Detecting and marking clipping

The clip indicators in the channel meters help you determine whether clipping occurs in your file, and you can use the Find command to find audio that matches levels you specify. For more control, however, you can use the Detect Clipping tool.

From the Tools menu, choose Detect Clipping to scan a selection of audio for clipping and add markers where clipping occurs.

Markers can be quickly selected from the list in the Go To dialog. Also, markers are displayed in the Regions List for quick playback.

1.Select the audio you want to scan.

2.From the Tools menu, choose Detect Clipping. The Detect Clipping dialog appears.

3.Choose a setting from the Preset drop-down list or adjust the controls as necessary.

a.Drag the Threshold slider to determine the sound level you want to find.

b.Set a value in the Clip Length box to specify how many sequential samples must meet the Threshold setting to constitute clipping.

4.Click the OK button.

The selection is scanned and a marker is added whenever there are a number of sequential samples (determined by the Clip Length setting) with the same value above the Threshold setting.

Tip: Use Detect all clip-related plateaus from the Preset drop-down list to detect clipped peaks that may exist in your file after decreasing the levels in the file. You can then use the Pencil tool or the Clipped Peak Restoration tool in the Sony Creative Software Inc. Noise Reduction plug-in to restore the clipped peaks.
