In its implementation section (§4.1, "Spatial Sound," addressing design goal DG1),
StereoMath's own text frames the mechanism as original: "Arguably some of our most
important innovations come from our spatial sound and spatial navigation... We also
change the pitch to match the vertical up/down location. In our co-design sessions,
this improved ease of comprehension, and provided a novel experience that was
previously not commonly found elsewhere." No citation is attached to this passage,
either here or at its first mention (design goal DG1, §3.2) — this is the paper's
own novelty framing for
[[claim-stereomath-2024-maps-equation-position-to-stereo-pitch-and-earcons|the exact
pitch mapping]] that
[[claim-aster-1994-rendered-math-as-pitched-spatial-audio|AsTeR implemented three
decades earlier]].

Read alongside
[[claim-stereomath-2024-cites-emacspeak-not-aster-as-generic-prior-art|the paper's
one, generic citation of Raman's Emacspeak]], the two passages are not in tension —
they are about different sources, in different places. The paper credits the
sonification *genre* broadly while separately and explicitly claiming the *specific*
pitch-for-vertical mechanism as its own, with no attribution at that point and no
mention of AsTeR anywhere in the paper. This is the evidence that resolves
[[observation-math-sonification-pitch-for-vertical-recurred-1994-2024]] toward
independent rediscovery rather than acknowledged lineage; see
[[question-does-stereomath-2024-cite-aster-emacspeak-pitch-mapping-prior-art]] for
the closed question thread.
