Package net.paulhertz.pixelaudio.sampler

package net.paulhertz.pixelaudio.sampler

Digital audio sampling synthesis classes for PixelAudio, built on the Minim library for Processing.

The package provides shared-buffer sample playback, polyphonic sampler instruments, ADSR envelope support, pitch and playback utilities, and event objects used by gesture-driven sampler workflows.

Sampler instruments and playback

• PASamplerInstrument manages sampler playback, global pitch, pan, gain, and default envelopes.
• PASamplerInstrumentPool manages a collection of sampler instruments for polyphony and reuse.
• PASamplerInstrumentPoolMulti manages multiple sampler pools, useful for multi-buffer or multi-sample playback.
• PASharedBufferSampler plays multiple sampler voices from a shared mono buffer, with voice pooling, looping, panning, gain control, and smooth voice stealing.
• PASamplerVoice handles one active sampler voice.

Interfaces and playback support

• PAPlayable is the root interface for playable or renderable audio objects.
• PASampler defines fundamental sampler methods, including play and buffer access.
• PASamplerPlayable extends PAPlayable for sample-based playback with gain, pitch, pan, and envelope parameters.
• PlaybackInfo stores information about sampler playback events.
• PitchPolicy defines pitch behavior for sample playback.
• SamplerBrushEvent stores gesture-derived sampler event data such as location, timing, sample position, gain, pitch, pan, and envelope.

Envelope utilities

• ADSRParams wraps parameters for ADSR envelopes.
• ADSRUtils provides utility methods for ADSRParams.
• SimpleADSR provides an executable ADSR envelope for sampler voices.
