Detailed Description
1D delay-line segment supporting both uni- and bidirectional propagation
UNIDIRECTIONAL (STRING): Only p_plus is active. Wave circulates in a single loop. p_minus is allocated but never written or read. Output tapped at pickup_sample along p_plus.
BIDIRECTIONAL (TUBE): Both rails active. p_plus travels toward the open end (bell), p_minus travels back toward the mouthpiece. At the closed end: p_minus[0] = -p_plus[end] (pressure inversion) At the open end: p_plus[0] = -p_minus[end] (approximate open reflection) Output is p_plus[pickup] + p_minus[pickup] (physical pressure sum).
Both rails share the same integer/fractional delay length and loop filter. The propagation mode is set once at construction and never changes.
