Fading regions to reduce artifacts

Audio may have unintended noises, such as hum or hiss, that are masked when audio like narration is playing but are audible when the narration stops. Other unintended noises can also occur, like “p-pops” (a “popping” sound that happens from the sudden burst of air associated with plosive sounds like “b” or “p”), clicks, mouth noises, and so on. Audition has advanced techniques for removing noise and doing audio restoration, but for simple problems, a fade is often all you need.

1. Choose File > Open, navigate to the Lesson03 folder, and open the file PPop.wav.

2. Zoom in and move the playhead to the start of the file. The keyboard shortcut to do this is Ctrl+left arrow (Command+left arrow). Note the spike at the beginning that corresponds to the “pop.”
