Setting And Applying Ambient Noise Print in Soundtrack Pro
Have you ever been out on a shoot and had to keyframe out a comment that was made by someone off screen? This used to be a common occurrence for me shooting guerrilla style for outdoor sports shows. Soundtrack Pro has a very nifty feature called "Set Ambient Noise Print" that will allow you to copy a section of your audio that is ambient noise and store it in a cache for later use in those areas you had to pot down . The good part is, if the segment you are trying to fill has a longer duration than the piece that you sampled, Soundtrack will automatically loop the ambient noise you stored. Obviously, you should use this sparingly, but its a great feature for those of us who shoot without a script.
Setting Ambient Noise Print
1 After you have brought your audio project into Soundtrack Pro, go to the waveform monitor and find a section of your audio that contains only ambient noise from the scene and select that segment by dragging the mouse point on screen.
2 Go to Process in the main menu and select Set Ambient Noise Print.
Applying the Ambient Noise Print
1 Drag a selection for the portion of the audio file that you had potted down.
2 Go to Process > Apply Ambient Noise.
