Class WindowCache

java.lang.Object

net.paulhertz.pixelaudio.granular.WindowCache

public final class WindowCache
extends Object

WindowCache Simple cache for windowFunction.generateCurve(length) results. Avoids recomputing window curves for the same (WindowFunction class, length) pairs. Implementation is thread-safe. For strict real-time safety, prewarm curves during setup, not from the audio thread.

Method Details

prewarm

public float[] prewarm(ddf.minim.analysis.WindowFunction wf,
 int length)

Precompute and cache a window curve. Call this during setup, not from the audio thread.

getWindowCurve

public float[] getWindowCurve(ddf.minim.analysis.WindowFunction wf,
 int length)

Get a cached window curve for the given WindowFunction and length. If not cached, this will lazily generate it. For strict real-time safety, prefer calling prewarm(...) ahead of time.
