Class GestureGranularRenderer.DefaultMapping

java.lang.Object

net.paulhertz.pixelaudio.granular.GestureGranularRenderer.DefaultMapping

All Implemented Interfaces:

GestureGranularRenderer.GestureMapping

Enclosing class:

GestureGranularRenderer

public static final class GestureGranularRenderer.DefaultMapping
extends Object
implements GestureGranularRenderer.GestureMapping

Default mapping for PixelAudio: - sample index from PixelAudioMapper.lookupSample(x,y) - optional mapping offset (totalShift) and modulo mapSize - soft pan range mapped from x across screenWidth Designed to be stateful: totalShift and panRange can change over time (e.g., sliding window through a larger buffer).
