java.lang.Object
net.paulhertz.pixelaudio.voices.PASamplerVoice
public class PASamplerVoice extends Object
PASamplerVoice — a single playback "voice" reading from a shared mono buffer. Each voice handles: - playback position and pitch - per-voice amplitude and pan - one independent SimpleADSR envelope (sample-accurate) - optional zero-crossing start and micro-fade-in Voices can be smoothly released and are recycled once the envelope finishes.
