Adding Ambient Noise

When editing an audio file, you may want to remove some sounds from the file while preserving the room tone or other ambient background noise in the file. Soundtrack Pro features commands you can use to set a selection as an ambient noise print and add the noise print to existing audio or replace the audio with the noise print.

Set Ambient Noise Print

The Set Ambient Noise Print command lets you copy part of an audio file containing only ambient noise that you want to add to another part of the file (or another file).

To set part of an audio file as an ambient noise print
  1. In the waveform display, select the part of the audio file containing only ambient noise.

  2. Choose Process > Set Ambient Noise Print.

The ambient noise is stored in a special buffer separate from the Clipboard and is saved to the project.

If you have copied audio to the Clipboard, you can set the contents of the Clipboard as an ambient noise print.

To set the contents of the Clipboard as an ambient noise print
  • Choose Process > Set Ambient Noise From Clipboard.

Add Ambient Noise

The Add Ambient Noise command adds the ambient noise stored in the ambient noise buffer to the audio file or selection.

To add ambient noise to an audio file
  1. In the waveform display, select the part of the audio file to which you want to add the ambient noise.

  2. Choose Process > Add Ambient Noise.

    The ambient noise is added to the selected audio. If the selection is longer than the copied ambient noise, the ambient noise repeats to fill the selection.

Replace With Ambient Noise

The Replace With Ambient Noise command replaces the selected audio with the ambient noise stored in the ambient noise buffer.

To replace existing audio with ambient noise
  1. In the waveform display, select the part of the audio file you want to replace with ambient noise.

  2. Choose Process > Replace With Ambient Noise.

    The ambient noise replaces the selected audio. If the selection is longer than the copied ambient noise, the ambient noise repeats to fill the selection.
