The Find Dialog

The Find dialog searches for clicks and pops, volume levels, or silent breaks in an audio file.

1. From the Tools menu, choose Find.

2. Chose a preset from the drop-down list or adjust the controls in the dialog box to specify what you want to find.

3. Choose a setting from the Find drop-down list to specify the type of data you want to find:

   Item	Description
   Glitch	Clicks and pops are unwanted sounds often found on worn records or on audio tape as a result of poor splicing, and they are seen as sharp glitches in the normal curve of a waveform. The glitch search algorithm looks at a waveform, starting at the cursor position, and determines when a glitch occurs based on the Threshold slope and Sensitivity settings. The cursor is then moved to the detected glitch to allow for further editing. You can use the Pencil tool to draw a smooth curve over the glitch to remove it.
   Level equal to or above	Finds the next point after the cursor position when the waveform reaches the level specified by the Threshold level fader.
   End of silent region	Moves the cursor to the end of the next silent break. Adjust the Threshold level fader to determine the sound level that will be treated as silence.
   Largest peak	Moves the cursor to the next largest peak amplitude. Searches progress from the current cursor position forward. To find the largest peak in a file, set the cursor to the beginning of the sound file or select all data before processing.

4. Drag the Threshold slope/level slider to determine the sound level you want to find:

   • When Glitch is selected in the Find drop-down list, drag the slider to determine the minimum slope (steepness) of the glitch. A high setting will only detect glitches with a high slope, while a low setting will detect both low and high-sloped glitches.

   • When Level equal to or above is selected in the Find drop-down list, drag the fader to determine the sound level you want to find.

   • When End of silent region is selected in the Find drop-down list, drag the fader to determine the sound level that will be treated as silence. The search will move the cursor to the next position where the level goes below and then back above the silence threshold level.

5. When Glitch is selected in the Find drop-down list, drag the Sensitivityslider to determine how the algorithm looks for glitches:

   • With a high Sensitivity setting, any part of the waveform with a slope above the Threshold slope is detected as a glitch.

   • Lower Sensitivity settings force the glitch finder to verify that the high-sloped waveform is a glitch and not part of the original, smooth waveform.

   If no glitches are detected, but you can hear clicks or pops, try decreasing the Threshold slope and/or raising the Sensitivity. If the search is falsely detecting glitches, decrease the Sensitivity and/or raise the Threshold slope.

6. Click OK. Sound Forge Pro software searches for the next audio data that matches your parameters and positions the cursor there.
