package net.paulhertz.pixelaudio.voices

Package net.paulhertz.pixelaudio.voices provides a hierarchy of Java classes for implementing digital audio sampling synthesis with support from the Minim library for Processing.

• PlaybackInfo maintains information about audio playback events, which it generates in response to play() and playSample() methods.
• ADSRUtils provides utilities for working with envelopes in ADSRParams format.
• ADSRParams provides a wrapper for parameters in Minim's ADSR class. Use it to create envelopes.
• SimpleADSR provides an executable ADSR envelope for PASamplerVoice.
• TimedLocation handles event scheduling.
• PAPlayable is the root interface for things that can play or render audio.
• PASampler provides an interface for fundamental sampler methods, including play() and setBuffer().
• PASamplerPlayable extends PAPlayable for sample-based playback (with parameters like pitch, gain, and envelopes).
• PASamplerVoice handles individual note playback (one per simultaneous note). It's a custom driver for audio which you don't need to instantiate directly.
• PASharedBufferSampler mediates between PASamplerInstrument and PASamplerVoice. It extends Minim's abstract class UGen. Instantiation is controlled through PASamplerInstrument.
• PASamplerInstrument manages a set of voices for polyphony and envelopes. Instantiate this in your code for basic audio sampler synthesis.
• PASamplerInstrumentPool manages a collection of PASamplerInstruments, supporting reuse and multi-sample configurations. Think of it as a section of instruments.
• PASamplerInstrumentPoolMulti manages a collection of PASamplerInstrumentPools: Think of it as the orchestra.
