public interface PAFloatSource

PAFloatSource Minimal, library-agnostic "audio source" abstraction for PixelAudio voices. It deals only with float[] buffers and sample indices, no Minim types. Implementations are expected to: - be called on the audio thread, - be allocation-free inside renderBlock().

Method Summary

Modifier and Type	Method	Description
long	lengthSamples()	Duration in samples, or Long.MAX_VALUE if effectively infinite/streaming.
void	renderBlock(long blockStart, int blockSize, float[] outL, float[] outR)	Render audio into the given block buffers.

Method Details

renderBlock

void renderBlock(long blockStart,
 int blockSize,
 float[] outL,
 float[] outR)

Render audio into the given block buffers. Implementations should: - Assume outL/outR length >= blockSize. - Mix into outL/outR (add), not clear them. - Avoid allocation on the audio thread.

Parameters:

blockStart - the absolute sample index in the source’s own sample domain (e.g., buffer index space).

blockSize - number of samples in this block.

outL - left channel buffer to mix into.

outR - right channel buffer to mix into (may be same as outL for mono).

lengthSamples

long lengthSamples()

Duration in samples, or Long.MAX_VALUE if effectively infinite/streaming.
