The Equalizer tool allows you to emphasize certain frequencies, specifying the amplitude and bandwidth.
The following graph is available:
|
Frequency Response Graph
|
Shows the frequency response. The y-axis represents the amplitude and the x-axis the frequency.
|
The following setting options are available in the Filter Settings area:
|
Drop-down menu
Filter
|
Selects the filters. The numbers in the Filters drop-down menu represent the squares in the Frequency Response Graph from left to right.
|
|
Slider
Center Frequency
|
Indicates the distribution of the handles on the x-axis. You can enter the values (in Hz) of the center frequencies in the fields.
|
|
Slider
Bandwidth
|
Indicates whether the bandwidth of the center frequency rises and falls steeply or gently. You can set a value between 0.1 and 3 octaves with the jog dial.
|
|
Slider
Gain
|
Specifies the amplification of the signal on the y-axis of the curve in the diagram.
|
The following settings are available in the Low Shelf area:
|
Check box
Low Shelf
|
Increases or decreases low frequencies.
|
|
Slider
Cut Off
|
Allows the filter to start after a certain frequency.
|
|
Slider
Gain
|
Specifies the degree of increase or decrease.
|
The following setting options are available in the High Shelf area:
|
Check box
High Shelf
|
Increases or decreases high frequencies.
|
|
Slider
Cut Off
|
Allows the filter to start after a certain frequency.
|
|
Slider
Gain
|
Specifies the degree of increase or decrease.
|
| Frequency |
The frequency denotes the oscillations per second of an electrical or magnetic field. With audio files this means that the frequency increases with rising pitch. The unit is Hertz (Hz). The highest magnitude of oscillation is called the amplitude.
