feedforward_compressor_worst_case_gain()

float pulp::host::dynamics::feedforward_compressor_worst_case_gain

(

)

Worst-case linear gain for the Forge registry (series law 8).

The topology is feedforward — the sidechain reads the input, never the output — so there is no loop to bound and no small-signal-gain argument to make. The gain computer can only ever reduce, so the bound is exactly the makeup ceiling: 10^(24/20). Asserted directly by the DSP suite's makeup-gain bound test rather than reasoned about here.

make_feedforward_compressor_node()

CustomNodeType pulp::host::dynamics::make_feedforward_compressor_node

(

float

lookahead_ms = 0.0f

)

The transparent/modern compressor as a lowerable custom node.

lookahead_ms is a construction-time realization axis because it changes intrinsic latency. Non-zero values therefore receive stable, collision-free type identities; the historical zero-lookahead node retains its base id.

kNodeMaxLookaheadMs

float pulp::host::dynamics::kNodeMaxLookaheadMs = 10.0f

inlineconstexpr

This node's lookahead ceiling, in ms.

The DSP header supports any value up to kMaxLookaheadMsCeiling; this is the value THIS node instantiates, which fixes the ring-buffer size at prepare() and therefore the largest latency the node can ever report. A future node can bake a larger ceiling without a header change. [design parameter] default 10 ms, range 0 .. 50 ms.
