Class MultiBand<T extends AudioSpectrum>

java.lang.Object

com.tagtraum.jipes.AbstractSignalProcessor<T,MultiBandSpectrum>

com.tagtraum.jipes.audio.MultiBand<T>

All Implemented Interfaces:

SignalProcessor<T,MultiBandSpectrum>, SignalPullProcessor<T,MultiBandSpectrum>, SignalSource<MultiBandSpectrum>

public class MultiBand<T extends AudioSpectrum>
extends AbstractSignalProcessor<T,MultiBandSpectrum>

Assumes that the input is spectral data produced by some Transform and sums up the powers into bins, which are spaced according to the provided frequency boundaries. Magnitudes are computed as square roots of the powers, the sum of the powers stays constant.
