Detailed Description

Processor implementing delay-line feedback via HistoryBuffer.

Applies a simple delay-line feedback algorithm: output[n] = input[n] + feedback_amount * delayed_sample

When attached to a FeedbackBuffer, uses its internal HistoryBuffer. When attached to any other AudioBuffer, maintains its own HistoryBuffer.

For filtering in the feedback loop (lowpass damping, etc.), chain a FilterProcessor after this processor rather than embedding filter logic.
