template<typename SampleType = float>
class pulp::signal::WaveguideLineT< SampleType >
A passive bidirectional waveguide segment.
left_in travels toward the right port and emerges as right_out; right_in travels toward the left port and emerges as left_out. Boundary reflection and intentional loss belong outside this class. The two rails use the shared prepared fractional-delay history, with double storage for both float and double public I/O. Lagrange-5 retuning is unity gain at DC and non-amplifying, but attenuates high frequencies at fractional delays; it is therefore passive rather than mathematically lossless.
prepare() is transactional and is the only allocating operation. All setters, process(), and reset() are bounded, lock-free, and allocation- free. Delay changes glide for five milliseconds because the live shared history exposes stateless Lagrange heads rather than a cross-interval Thiran retune operation.
