Audio Postproduction and Audio Effects
Reverb
This effect determines sound character by simulating the rooms in which tones/sounds/noises are cre-
ated and perceived. The reflection of soundwaves (commonly referred to as echo) plays an important
part. The size of the room and the nature of the reflecting surfaces create differences in the direct percep-
tion of the sound source and in the delayed perception altered by reflection.
A number of room simulations are available.
The following parameters allow you to configure individual acoustic spaces (Tip: Start with a similar
preset):
 Initial Delay -
This parameter determines the starting time for the first “early reflection”, i.e. how the sound is
reflected off the walls in the simulated room. Values range from 0 to 500 milliseconds. The lower
the value, the earlier this initial reflection is audible.
 Room Size -
This setting determines the “size” of the simulated room and, therefore, the depth of the rever-
beration. Values range from 1 to 30. The higher the specified value, the larger the simulated rever-
beration space.
 Damping -
This parameter serves to attenuate the high frequencies in the reverberation in order to generate a
softer, warmer sound. The higher the value, the more the high frequencies are attenuated.
 Duration -
This parameter determines the duration of the reverb effect.
 Mix -
This parameter defines the ratio of the effect signal to the original unedited audio signal. When
the slider is set to the center position (default), the ratio is balanced. When moved all the way to
the left, only the original signal is audible.
Equalizer
This is a ten-band equalizer for determining the sound characteristic. It allows you to emphasize or sup-
press specific frequency ranges. Values range from -24 to +24 dB.
A number of standard scenarios are available in a list. Selecting Flat sets all the bands to zero.
