File References

If you listen to Dogs.wav very closely, you can hear dogs very far in the background. You may have even cut one off. We don’t want that in our file, so let’s get rid of them. But since we’ve split this block, that would be really time consuming to look at each one. But good news, if we adjust the original file, all the blocks will be updated!

• Start by either double clicking one of the Dog blocks or opening Dogs.wav.
• You are now back in Waveform view.
• There are two simple ways to remove these distant barks. The first is to use Effects > Silence. This will require that we identify where those barks are located. To help we can zoom in vertically by scrolling over the far right side or clicking on the vertical zoom button. The audio wave will look like it’s peaking, but it’s really just zoomed in.
  To restore our panel we can press the Zoom Out Full button.
• The second method, the better method, is to use Effects > Dynamic Processing to create a gate. A gate is the inverse of a compressor and cuts out sounds that are quieter than a given threshold.
• So highlight a section of distant barking and create a gate based on the Electric Guitar Gate
  Adjust the preset until the distant barking is unintelligible.
  
• If you select more of the file, you might notice that an aggressive gate could cut off the beginnings of the barks that we want to keep. Here I’ve also adjusted the Make-Up Gain to 0dB so that we’re not also amplifying the audio.
  
• We could also use the Look Ahead Time under the settings panel to to make things less aggressive.
  
• Hit apply and return to multitrack view.

Notice that the changes you made in Waveform persisted into Multitrack.
