make_tape_machine_node()

CustomNodeType pulp::host::tape::make_tape_machine_node	(	Archetype	archetype,
		double	speed_ips = 0.0,
		bool	pre_echo_enabled = false )

One factory, three registered realizations.

speed_ips is snapped to the archetype's legal set by the DSP, so passing 30 to a cassette node yields 1.875 rather than an error — the same behaviour set_speed_ips has, and the reason a caller does not need the legal table.

normalized_archetype()

Archetype pulp::host::tape::normalized_archetype ( Archetype archetype )

inlinenoexcept

tape_default_name()

const char * pulp::host::tape::tape_default_name ( Archetype archetype )

inlinenoexcept

tape_machine_insertion_gain_bound()

float pulp::host::tape::tape_machine_insertion_gain_bound	(	Archetype	archetype,
		double	sample_rate )

The largest gain any single stage of this insert can present, at the realization's own speed and the given sample rate.

This is what the registry cites in place of worst_case_gain, which does not apply. It is deliberately NOT a small number, and the DSP header explains why at length: a reproduce network for a curve with no bass shelf is (1 + s·t₂), a differentiator, so its ceiling near Nyquist is set by the standard's own prototype and grows with the sample rate. The programme never sees it — the record network is that section's exact reciprocal — and the suite asserts the consequence directly by bounding the module's output on silence and at full scale.
