Lancet is the dynamic EQ of the Basilica Audio suite — sacred-architecture DSP for heavy music: six surgical bands whose gain moves with the program material, named after the lancet window, the narrowest of Gothic arches.

This is the first tagged release (v0.1.0), covering the M1 milestone: core DSP and test coverage.

What's in 0.1.0

  • Six-band dynamic EQ engine: RBJ bell filters (Bands 1/6 switchable to Low/High Shelf), each combining a static gain with a soft-knee dynamic gain (up to ±12 dB Range, upward or downward) driven by its own detector.
  • Per-band detectors tap the pre-chain signal through a selective cascaded bandpass, so no band's move disturbs another's detection; attack/release ballistics per band.
  • Zero latency (minimum-phase biquads only, no lookahead), coefficient updates smoothed in 32-sample sub-blocks (no zipper noise).
  • Exclusive per-band Listen (audition exactly what a band's detector hears), global Input/Output Trim and parallel Mix.
  • 47 Catch2 tests: bit-transparent null at neutral settings, analytic magnitude references, dynamic convergence, detector isolation, NaN/Inf recovery, oversized blocks, state round-trip, zipper guard. pluginval (strictness 10) + auval green in CI.
  • Full user manual and engineering notes.

Honest status notes

  • Voicing: v0.1.0 is the engineered core — correct, tested, transparent. A dedicated voicing/character pass (musical default curves, program-dependent refinements) follows in M2.
  • Presets: the suite-wide preset system (factory presets, user presets, default, import/export) is scheduled for M2.
  • GUI: functional slider editor; the photoreal skeuomorphic interface lands in M3.

Formats

Platform Formats Notes
macOS 11.0+ AU, VST3, Standalone universal (Apple Silicon + Intel)
Windows x64 VST3, Standalone

Install by copying AU/Lancet.component to /Library/Audio/Plug-Ins/Components and/or VST3/Lancet.vst3 to /Library/Audio/Plug-Ins/VST3 (macOS) or C:\Program Files\Common Files\VST3 (Windows). Rescan plugins in your DAW after installing.

Signed & notarized

The macOS binaries in this release are Developer-ID-signed, notarized by Apple and stapled — they install and open without Gatekeeper warnings. (Windows binaries remain unsigned for now; Authenticode signing is tracked as roadmap milestone M4.)
