Module hrtf 

HRTF — analytic + KemarLite embedded tables (zero-heap hot path).

Full measured KEMAR datasets are optional cold assets; default hot path uses KemarLite (8-azimuth ITD/ILD samples) with analytic fallback.

Structs

BinauralGains

Binaural staging gains + ITD for stereo worklet.

Enums

HrtfProfile

HRTF synthesis profile (hot path).

Functions

binaural_analytic

Analytic binaural gains — azimuth ∈ [-π, π], elevation ∈ [-π/2, π/2].

binaural_from_position

Dispatch binaural model from active HrtfProfile.

binaural_kemar_lite

KemarLite binaural — interpolated embedded ITD/ILD tables.

binaural_render

Render a mono source at source (world space) into a binaural pair.

convolve_fir

Direct linear (FIR) convolution: y[i] = Σ_j signal[j]·h[i-j].

head_relative_position

Rotate source position into head frame (listener at origin, yaw around Y).

hrtf_profile

room_damp_from_manifold

Manifold w biases room absorption (higher w → softer highs).

set_hrtf_profile

synthesize_hrir

Synthesize left/right HRIRs from gains.
