The radar
Drag to place the source in 3D — angle and distance. The whole field on one screen.
The deep engine.
ORBIT is the flagship: a full binaural spatial engine. Place a sound anywhere around you, set it orbiting, or fly it past with real Doppler. Headphones or speakers — mono-safe with IN PHASE.
Doppler
Bends the orbit eccentric: the source flies close then far, pitch rising and falling. A real fly-by.
Rate / Speed
Free, tempo-synced (1/4–1 bar), or Fixed placement. The orbit follows your track.
Chaos
Erratic, alien motion — darting speed and azimuth wobble.
Width / Room
Ear-shadow width plus decorrelated early reflections that push the sound outside your head.
Output / In Phase
Headphones or speakers (crosstalk-cancelled). IN PHASE guarantees mono.
Real binaural, measured.
ORBIT is the conservative, pure binaural core — no tricks, just acoustics.
Binaural HRIR
A variable-position HRIR spatializer: two bracketing voices crossfade with fractional-delay ITD, so the source moves without clicks.
Near-field
Under a meter, Duda–Martens proximity: bass bloom and asymmetric ear-shadow. The source gets intimate.
Real Doppler
Pitch emerges from propagation delay — no pitch-shifter, no reported latency.
Externalization
Early reflections (Room) lower interaural coherence, so sound leaves your head.
Speakers (RACE)
Crosstalk cancellation for speakers, with no added latency in the crosstalk stage; IN PHASE drops it for mono.
Peak-held output
A stereo-linked sample-peak limiter holds the internal peak at −1.4 dBFS; OUTPUT and the filters sit after it (measured true-peak −1.2 dBFS with pink noise, up to −0.05 dBFS with full-scale broadband material).
