Class ConstantQTransform

java.lang.Object

com.tagtraum.jipes.AbstractSignalProcessor<AudioBuffer,LogFrequencySpectrum>

com.tagtraum.jipes.audio.ConstantQTransform

All Implemented Interfaces:

SignalProcessor<AudioBuffer,LogFrequencySpectrum>, SignalPullProcessor<AudioBuffer,LogFrequencySpectrum>, SignalSource<LogFrequencySpectrum>

public class ConstantQTransform
extends AbstractSignalProcessor<AudioBuffer,LogFrequencySpectrum>

Processes input using a transform created by ConstantQTransformFactory. Since constant Q transforms are often initialized with arguments from the AudioFormat the transform is created at runtime with the first input AudioBuffer using a ConstantQTransformFactory.
