Technology

DSP engine built
for real-world demands.

Every component implements its full specification — not a prototype approximation.

🎧

HRTF Binaural (TDS §5.1)

Woodworth-Schlosberg spherical model with 14 dB ILD @ 90°. Bilinear interpolation over 36×7 grid. Hann adaptive crossfade based on angular velocity.

🌐

Ambisonics FOA/HOA (SN3D)

Vector encoder up to order 7. Associated Legendre with numerical recurrence. Controllable scene diffusion per source channel.

⚡

WOLA Convolution (TDS §6.2)

Partitioned WOLA convolution in 128-sample blocks. FDL (Frequency Delay Line) with overlap-add. Guaranteed minimum latency.

📊

ITU-R BS.1770-4 Metering

Integrated LUFS with two-stage K-weighting filter and True Peak at 4× oversampling. Compliant with broadcast and streaming standards.

🔗

Linkwitz-Riley Q31 Crossover

Deterministic Q31 fixed-point arithmetic, cross-platform. Guaranteed flat sum. Also available in high-fidelity f32.

🔐

Audit & Reproducibility

SHA-256 hash of input PCM and parameter snapshot per session. 100% reproducible and identifiable renders.

🎚️

User Calibration Profile

JSON profile with 1/3-octave ILD curve, diffuse-field EQ, ITD offset ±150 µs, and externalization level. Integrity checksum included.

🔊

Early Reflections

3 reflection taps (1.5 / 2.5 / 4.0 ms) for controlled externalization. Configurable level from user profile.

🖥️

Integrated egui GUI

Native in-DAW interface: sliders for azimuth, elevation, distance, width, and externalization. No external UI dependencies.
