Method Detail

setAmplitudeLinear

public void setAmplitudeLinear(float fAmplitude)

Set the amplitude. The value passed here is the value the samples are multiplied with. So 1.0F means no change in amplitude. 2.0F doubles the amplitude. 0.5F cuts it to half, and so on. This is in contrast to setAmplitudeLog, where you can pass the amplitude change as dB values.

setAmplitudeLog

public void setAmplitudeLog(float fAmplitude)

Set the amplitude. The value passed here is in dB. So 0.0F means no change in amplitude. +6.0F doubles the amplitude. -6.0F cuts it to half, and so on. This is in contrast to setAmplitudeLinear(), where you can pass the amplitude change linear values.

process

public void process(FloatSampleBuffer buffer)

Do the amplifying. Here, simply each sample in each channel is multiplied with the amplitude value.
