BoxRIR 0.3.0 adds path-dependent six-band wall materials and atmospheric loss to the standalone MoonBit RIR engine.

  • Each valid reflection path applies wall-specific energy-to-pressure coefficients and physical-distance air loss before complementary FIR synthesis. This is not a final global EQ. New mode supports both shoeboxes and convex prisms.
  • Atmospheric equations are adapted from pinned Python Acoustics BSD-3-Clause code, with explicit Celsius / percentage humidity / kPa units. Existing AudioLabs compatibility waveforms remain unchanged. Source SHA manifests and all licenses are included.
  • Band FIR resolution scales with sample rate. Independent centre-frequency response tests catch under-resolved material bands that a waveform comparison alone could miss.
  • Subagent reviews identified and the primary agent fixed candidate-count semantics, per-receiver prism diagnostics, missing wet:null in the typed SDK contract, repeated geometry work, unknown/ancestor build provenance and stale version-specific packaging tests.

Validation: 31 MoonBit tests per backend, 31 Node tests; original 103 AudioLabs cases / 155130 Float64 samples; 12 new independent SciPy cases / 29786 samples, plus 36 atmospheric cases; actual WAV/convolution checks and nine browser scenarios. Local archive consumers pass 35 tests per target (31 library + four public-consumer tests). Exact-source Linux Native, JS, Wasm, Wasm GC, Chromium and packaging CI passed:

Mooncakes 0.3.0 is published and verified. A new project with no local workspace installed the exact registry version and passed four public-consumer tests on each of JS, Wasm and Wasm GC. The official anonymous archive, registry checksum, cache ZIP and installed source contents agree:
https://mooncakes.io/docs/zhangbowen2006/boxrir@0.3.0

Install: moon add zhangbowen2006/boxrir@0.3.0

The standalone runtime ZIP requires Node 24+, with no MoonBit/Python/C++ compiler needed. It includes SDK/CLI, examples, exact clean source provenance and per-file checksums. Verify downloaded archives with SHA256SUMS.txt; verification.json records local/CI/registry evidence.

This remains a bounded offline specular simulator. No obstacles, scattering/diffraction, moving or scheduled multiple sources, real-room calibration or external user-adoption claims. Six material bands are finite FIR/centre-frequency approximations; endpoints extend to DC/Nyquist and no IEC/ISO certification is claimed. Temperature controls air loss while sound speed stays explicit. Performance and memory depend on the target machine. Application resubmission, review acceptance and quarterly eligibility are not implied by this release.
