Class Aggregate<C,E>

java.lang.Object

com.tagtraum.jipes.AbstractSignalProcessor<C,E>

com.tagtraum.jipes.universal.Aggregate<C,E>

Type Parameters:

C - collection of values

E - the type of the aggregated values

All Implemented Interfaces:

SignalProcessor<C,E>, SignalPullProcessor<C,E>, SignalSource<E>

public class Aggregate<C,E>
extends AbstractSignalProcessor<C,E>

Applies an AggregateFunction like AggregateFunctions.ARITHMETIC_MEAN to each provided collection (usually a RealAudioBuffer or a float array).
