Apollo texture evaluation — real music and memory evidence
Pre-release
Review material for JusperLee#44 — not an approved Apollo release.
Eight aligned 15-second real-music excerpts with raw WAVs (source proxy, degraded input, upstream Apollo at 0 dB and that exact prediction at 1/2/3 dB), randomized BS.1770 loudness-matched blind copies, a single-player HTML audition page, source hashes, reproduction scripts and memory measurements. No lossless clean master or controlled listening result is claimed. The low-level case has a documented -18 dB input gain before inference. All cases, including objective adverse/caution results, are retained.
The full-output STFT remains expensive: a 180-second probe repeating real Apollo output measured about 2328.6 MiB peak tracked allocations / 3042.2 MiB process RSS, excluding the model.
33 tests passed locally and on pinned Linux CPU CI: https://github.com/hemanpapa-coder/Apollo/actions/runs/38918654428 . Upstream CI requires maintainer approval. Keep PR Draft pending listening.
