Nonexistent Peak and RMS levels
Note: If the RMS level never reaches the Ignore below threshold, a value of
Use current scan level (do not scan selection)
When you select the Use current scan level check box, Sound Forge uses the current scan levels without initiating a new scan. This is useful when applying scan levels from a different selection or file to the current selection, thereby allowing identical gains to be applied to multiple files. This option can also be used to scan a selection of an audio file containing the loudest or most constant levels and then apply that scan to normalize the entire file.
If clipping occurs
The If clipping occurs
Option | Description |
Apply dynamic | Audio peaks that will result in clipping are limited below 0 dB using |
compression | release times to minimize distortion. This mode is useful for getting loud and clear audio |
| during mastering. |
Normalize peak value to | The selection’s peak amplitude level is normalized to 0 dB, thereby allowing the |
0 dB | maximum possible constant gain without clipping the selection. However, less gain is |
| applied than would be necessary to achieve the Normalize to RMS level. |
|
|
Ignore (saturate) | Audio is permitted to clip and distort. |
Stop processing | Audio peaks that will result in clipping force the normalize function to cease processing |
| and alert you that clipping will occur at the current level. |

Note: When normalizing stereo audio, normalization is computed on the loudest sample value found in either channel and identical gain is applied to both channels. If a single channel is selected in a stereo file, normalization processes only that channel.
Pan/Expand
Pan/Expand allows you to create panning effects and stereo compression/expansion in selections.
Note: The Expand option is only available in the full version of Sound Forge.
