Module preview 

BA display curves replayed from an immutable design, without fitting.

Structs

SubCombine

Sub-combination preview; all curves are reference-position dB values.

SubValue

The sub’s exported alignment, on the output time axis.

XoCurves

Reference-position XO display curves, all in dB except the Hz grid.

XoPreview

Immutable per-design responses; building once keeps slider calls below R7’s 0.2 s budget. Rebuild this cache whenever the design changes.

Functions

sub_combine

Replays before/after sub responses, returning None for fewer than two subs. Fixed filters remain in the raw spectra, matching upstream’s H0; generated bundle filters and bus PEQ appear only after alignment. Does not rerun BA.
