Class for Equalizer Bands Equalizer bands have three controllable parameters: enabled/disabled, cutoffFrequency and gain
Public constructors | |

public EqBand (boolean enabled, float cutoffFrequency, float gain)
Class constructor for EqBand
Parameters | |
---|---|
enabled |
boolean : true if this band is currently used to process sound. When false,
the band is effectively muted and sound set to zero. |
cutoffFrequency |
float : topmost frequency number (in Hz) this band will process. The
effective bandwidth for the band is then computed using this and the previous band
topmost frequency (or 0 Hz for band number 0). Frequencies are expected to increase with
band number, thus band 0 cutoffFrequency <= band 1 cutoffFrequency, and so on. |
gain |
float : of equalizer band in decibels (dB). A gain of 0 dB means no change in level. |
public EqBand (DynamicsProcessing.EqBand cfg)
Class constructor for EqBand
Parameters | |
---|---|
cfg |
DynamicsProcessing.EqBand : copy constructor |
public float getGain ()
gets current gain of band in decibels (dB)
Returns | |
---|---|
float |
current gain of band in decibels (dB) |
public void setGain (float gain)
sets current gain of band in decibels (dB)
Parameters | |
---|---|
gain |
float : desired in decibels (db) |
public String toString ()
Returns a string representation of the object. In general, the
toString
method returns a string that
"textually represents" this object. The result should
be a concise but informative representation that is easy for a
person to read.
It is recommended that all subclasses override this method.
The toString
method for class Object
returns a string consisting of the name of the class of which the
object is an instance, the at-sign character `@
', and
the unsigned hexadecimal representation of the hash code of the
object. In other words, this method returns a string equal to the
value of:
getClass().getName() + '@' + Integer.toHexString(hashCode())
