pyFDN.FDNBuild

class pyFDN.FDNBuild(A, B, C, D, delays, fs, post_delay=None, post_matrix=None, post_output=None)

Complete, renderable parameters of a vanilla FDN.

Every field is a plain NumPy value consumed by pyFDN.process_fdn() and pyFDN.build_to_impz(). A build does not remember how its numbers were designed; that optional information belongs to pyFDN.FDNPreset.

The three optional SOS banks correspond directly to pyFDN’s filter hooks:

• post_delay has shape (sections, 6, N) and sets the decay inside the loop after the delays.

• post_matrix has shape (sections, 6, N) and filters the feedback path after the feedback matrix.

• post_output has shape (sections, 6, outputs) and filters the wet signal outside the recursion.
