java.lang.Object
net.paulhertz.pixelaudio.granular.PAGranularVoice
public class PAGranularVoice extends Object
PAGranularVoice A single granular "voice" driven by a PASource. Provides: - nextSample() API so it can be mixed like PASamplerVoice - voice-level ADSR envelope (macro envelope) - per-voice amplitude + pan - optional looping of entire grain path Internally uses: - Block buffer (blockL / blockR) - Absolute sample counter (absSample) - Cursor into current block
