The Unity Recorder (5.1.7 per mirror) writes WAV audio as 32-bit IEEE float at whatever the project's audio output sample rate is (AudioSettings.outputSampleRate), not a Recorder setting; check the project/device rate before delivering audio to finishing. Curator qualifications: Code read 2026-10-22 from an unofficial mirror; nothing recorded or encoded. Source is needle-mirror (unofficial mirror of the Unity Recorder package); byte identity with the Unity-distributed package not verified. Docs-page absence of a sample-rate setting from producer reading. Curator amendment CA-AM-0039 (2026-10-22): Scope note (curator, from C3R-0449 / C3-B222-G68): these statements are code_derived_inference from the needle-mirror source whose package.json matches the official UPM 5.1.7 registry metadata; file-level identity with the official tarball is unverified. Official Unity docs state none of them (no sample rate/bit depth; no PNG/JPEG sRGB forcing beyond EXR-only linear option; no ProRes colour definition). Cite them as code-level behaviour of the mirrored 5.1.7 source, not documented behaviour. Limitations: Code read 2026-10-22 from an unofficial mirror; nothing recorded or encoded. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
