gen_audio.py: a numpy synthesis engine (osc / ADSR / filters / reverb /
seamless-loop crossfade + note sequencer + drum synth). Renders 6 ambience
beds (street day/night, rain, 3 interior roomtones) + 13 sfx (doorbell,
door, till, record-riffle, toast, tram bell/rumble, 6 footsteps) + 4
instrumental 90s music loops (record-shop, milkbar, video-synth, arcade)
-> web/assets/audio/ as OGG/Opus + M4A/AAC. 8.1 MB of the 25 MB budget.
Tool = 100% procedural synthesis (not a neural model): $0, deterministic/
seeded, perfectly loopable, parody-safe by construction. Documented in
README (§ audio) + AUDIT.md provenance.
manifest audio:{ambience,sfx,music} — file + m4a fallback + loop + gain;
interior roomtone/music carry types[] (seed-pick per shop, like facades);
footstep is {surface:[variants]}. build_manifest.py builds it,
validate_manifest.py checks it. qa.sh --strict green (audio 23, 0 err).
Verified technically (peaks <= -0.4 dBFS, all loops seamless, durations)
via spectrogram sheet + numeric — subjective ear-check is John's/F's.
E leads the audio round; F owns the v2.1 tag + push. Not pushed.

Note on night_crowd (Lane F, R10)
Re-framed to the tighter, readable "one lit shop in a closed town" composition. It does not show a
standing street crowd, and that is not a framing bug: Lane D's night patronage parks ducked-in patrons
hidden inside the shop (they become the interior browsers seen in browsers.png), and seed 20261990's
video shop sits on a low-traffic corner, so none gather visibly outside (tested: 0 patronage / 0 visible
at night). The town's night life is the interior presence + the neon-vs-CLOSED mood. A visible outdoor
night queue would need a new Lane-D mechanic (loiter-outside-the-openLate-shop) — parked for v3. The
~20 fps in night captures is a headless-chromium software-GL artifact (the scene is light, ~128
draws / 65k tris); on real hardware the night scene is not a perf concern.
Regression workflow
Before a risky change, snapshot the good state into before/, then re-run v2_tour.py and eyeball
v2_contact.html. Process rule (R10): any shot containing a humanoid gets an explicit
"figures human-sized relative to doors/fittings: yes" line in the progress note — actually look.
