Class FuzzboxEffect

java.lang.Object

audio.processing.distortion.FuzzboxEffect

public class FuzzboxEffect
extends java.lang.Object

A Fuzz-box distortion Effect which allows user to apply a distortion effect on the audio by lowering the 'acceptable' threshold level to force clipping. The user can compensate for the loss in volume caused by limiting the threshhold by adjusting the gain level using the GUI.This effect does not need to extend AudioEffect16bit to deal with chunks as no forwardBuffer is added to the signal.

             int threshold)

Method Detail

setGain

public void setGain(float vol)

Sets the volume or 'gain' level. To be specific this sets how loud the signal will be. The entire array for the wave is multipled by this value. In order to increase volume, a value greater than one is used. Using a value of less than one decreases the value.

Parameters:

vol - volume level. This value should be less than one in order to decreases the volume. A value more than one increases the volume

setThreshold

public void setThreshold(int thresh)

Sets the maximum acceptable threshold level for the amplitude of values in the array. Decreasing the threshold of acceptable values results in MORE distortion.

Parameters:

thresh - threshold value for distortion. Decreasing the threshold of acceptable values results in MORE distortion

process

public short[] process(short[] input)

Allows user to distort the audio signal (by forcing the signal to clip) and also adjust the volume of the input sample to compensate for the lower output level. Works in 32bit.

(ints) to avoid any (unintentional) clipping from using shorts, however the limiter would rarely be used.

Parameters:

input - short array containing the input data to be manipulated by algorithm
