Purpose​

3D spatial audio engine with HulyaPulse-synced HRTF. Zeqond-quantized reverb tails, Doppler simulation, occlusion via R(t)-weighted ray casting. It belongs to the Physics Engine, Procedural Gen, Netcode, AI, Audio family and is callable as a single REST endpoint, a one-line SDK call, or via streaming where applicable.

What it does​

When you call /api/gaming/spatial-audio, Zeq runs the ZeqSpatialAudio computation through the KO42 metric tensioner under the active HulyaPulse phase. The result is sealed at the next Zeqond boundary (0.777 s) and returned with a verifiable ZeqProof receipt — meaning the same inputs at the same phase always produce the same output, and any third party can later verify the result was computed at the time you claim.

In practice, this protocol takes the parameters listed below, performs its physics engine, procedural gen, netcode, ai, audio operation, and returns a structured response containing the computation output plus phase-locking metadata (zeqondTick, hulyaPhase, zeqProof).

When to use it​

Reach for ZeqSpatialAudio when you need a physics engine, procedural gen, netcode, ai, audio primitive that:

  • Must be reproducible — every call is deterministic for a given phase
  • Must be auditable — every response carries a tamper-evident ZeqProof receipt
  • Must compose with other Zeq protocols — outputs are phase-aligned to 1.287 Hz so they slot directly into downstream calls without resync
  • Must scale across domains — the same endpoint works whether you're driving one call per minute or part of a high-throughput pipeline (subject to rate limit 30/min)

If you only need a one-shot physics engine, procedural gen, netcode, ai, audio answer with no audit trail and no composition with other Zeq calls, a plain library may be cheaper. If you need any of the four properties above, this protocol is the right tool.

How to call it​

The fastest path is a single HTTPS POST request to /api/gaming/spatial-audio with a Bearer token. You can use cURL, JavaScript, Python, or any HTTP client — examples for all three are below. The response is JSON.

Parameters​

No required parameters. Send an empty JSON body {} or include domain-specific fields.

Returns​

{ spatializedAudio, hrtfApplied, reverbProfile, dopplerShifts, zeqond }

How to call it — every language​

Every Zeq endpoint is a plain HTTPS POST. That means you can call it from any language that speaks HTTP. Below: thirteen working snippets — pick whichever fits your stack.

Phase-Locking & ZeqProof​

Every response from /api/gaming/spatial-audio carries:

  • zeqondTick — the Zeqond (0.777 s) at which the result was sealed
  • hulyaPhase — the HulyaPulse phase ∈ [0, 1) at sealing
  • zeqProof — HMAC receipt that lets any third party verify the result without an API key via POST /api/zeq/prove/verify

See Concepts → ZeqProof and HulyaPulse for the underlying mathematics.
