Still, if you have a clip with a lot of pops, this filter may reduce these to an acceptable
level.
Echo and Reverberation Filters
Two of the “effects” filters you’ll use most frequently are the Echo and Reverberation
filters. You can use reverberation to add the reverberation effects of a particular acoustic
space to a sound that was recorded in isolation. Be careful not to add too much
reverberation because it muddies the clarity of the sound (especially dialogue) and, more
often than not, it can sound artificial. When possible, it’s best to rerecord dialogue in the
same, or similar, environment as the original production.

settings
Both Echo and Reverberation filter settings are described below.
• Effect Mix: This slider determines how much of the “dry,” or original, sound from the
audio clip is mixed with the affected audio. By keyframing this parameter over time,
you can make it sound as if someone were walking from far away in a room (where
there would be more reverberation) toward the microphone (where there would be
less reverberation the closer they came).
• Effect Level: This slider defines how loud the reverberation or echo effect is.
• Brightness: This slider affects the quality of the reverberation or echo. Boosting this
parameter makes the effect seem more intense.
• Feedback: This slider (Echo only) affects how long the echoes produced by the filter
last. As they repeat, they’ll interact with themselves to produce a complex series of
echo effects.
• Delay Time: This slider (Echo only) lets you determine the pause, in milliseconds, between
each echo. The longer the pause, the bigger the apparent space of the environment.
