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.

# PROCITY pipeline (Lane E) — how to re-run everything
|
||
|
||
The asset pipeline: audit ultra's library → normalize the good bits to house GLB law → publish
|
||
to the 3GOD depot → ship `web/assets/manifest.json` (the contract Lanes B/C/D read) → fill facade
|
||
+ prop gaps. **Everything is optional at runtime** — the game runs asset-free; this lane makes it
|
||
gorgeous, it doesn't make it work.
|
||
|
||
## Where things live
|
||
|
||
| what | where |
|
||
|---|---|
|
||
| ultra (library + Blender) | `ssh johnking@100.91.239.7` — key auth, **no** coreutils/timeout, py3.9, Blender at `/Applications/Blender.app/Contents/MacOS/Blender` (not on PATH) |
|
||
| model library | ultra `~/Documents/3D=models/{shop-fittings,street-furniture,furniture,props-scenes}` |
|
||
| 3GOD depot | `https://digalot.fyi/3god` — `GET /a/<f>`, `GET /api/list`, `POST /api/upload?name=<f>` |
|
||
| OpenRouter key (skins) | env `OPENROUTER_KEY` or `~/Documents/dealgod/lore/keys.env` (never committed) |
|
||
| depot password (publish) | env `GOD3_PW` (never committed; ask John) — cookie = `hmac(GOD3_PW,"3god-ok")` |
|
||
| Ollama (free LLM) | `http://100.89.131.57:11434` (qwen3) — for names/lore/cataloguing, unused so far |
|
||
| MODELBEAST (free local gen) | this box, `~/Documents/MODELBEAST`. `flux_local` = FLUX.2-klein-4B text→image on MPS (**used for the facade skins** — ungated, weights cached). `sf3d`/`trellis_mac` = image→GLB, local but HF-gated (setup needed) |
|
||
|
||
## The steps (each is idempotent / resumable)
|
||
|
||
### 1. Audit — `AUDIT.md` *(free)*
|
||
```bash
|
||
scp pipeline/glb_stat.py johnking@100.91.239.7:/tmp/
|
||
ssh johnking@100.91.239.7 'cd ~/Documents/3D=models && python3 /tmp/glb_stat.py --json shop-fittings street-furniture furniture props-scenes' > pipeline/_audit_stats.json
|
||
```
|
||
`glb_stat.py` is a dependency-free GLB parser (tris, bbox, texture sizes, Draco flag). Findings +
|
||
licensing triage are written up in `AUDIT.md`.
|
||
|
||
### 2. Normalize — `normalize.py` → 16 GLBs + thumbs *(free, runs on ultra)*
|
||
```bash
|
||
scp pipeline/normalize.py pipeline/batch.json johnking@100.91.239.7:/tmp/
|
||
BL=/Applications/Blender.app/Contents/MacOS/Blender
|
||
ssh johnking@100.91.239.7 "\$BL --background --python /tmp/normalize.py -- /tmp/batch.json /tmp/procity_norm"
|
||
scp johnking@100.91.239.7:/tmp/procity_norm/_results.json pipeline/_normalize_results.json
|
||
scp 'johnking@100.91.239.7:/tmp/procity_norm/thumbs/*.png' web/assets/thumbs/
|
||
scp 'johnking@100.91.239.7:/tmp/procity_norm/*.glb' pipeline/_normalized/
|
||
```
|
||
Enforces the house GLB law (metres, +Y up, base origin, ≤5k tris, WebP ≤1024, no Draco), renders a
|
||
256px thumbnail each. Extends `MESHGOD/scripts/finish_glb.py` (solidify/decimate/bright/base-origin)
|
||
+ adds texture-webp, height-normalize, outlier cleanup, per-asset up/yaw. Edit `batch.json` to add
|
||
assets; **always eyeball the thumbnails** — node-transform-distorted sources (see AUDIT rejects)
|
||
look fine in-frame but have wrong footprints.
|
||
|
||
### 3. Manifest — `build_manifest.py` + `validate_manifest.py` *(free)*
|
||
```bash
|
||
python3 pipeline/build_manifest.py # → web/assets/manifest.json
|
||
python3 pipeline/validate_manifest.py # Lane F gate: 0 errors = green
|
||
python3 pipeline/validate_manifest.py --depot # stricter: require GLBs live on the depot
|
||
```
|
||
`build_manifest.py` derives skins from `web/assets/gen/` + fittings from `_normalize_results.json`;
|
||
the curated facade→shop-type maps live at the top of that file (edit there when adding skins).
|
||
|
||
### 4. Publish — `publish.py` → 3GOD depot *(the one outward-facing step)*
|
||
```bash
|
||
python3 pipeline/publish.py --dry-run # free: list what would upload
|
||
export GOD3_PW=... # ask John
|
||
python3 pipeline/publish.py # POST each GLB + thumb to the depot (idempotent)
|
||
```
|
||
|
||
### 5. Facade skin gaps — `gen_skins.py --local` *(DONE, free, on-device)*
|
||
The 23-skin gap pack is **already generated + harvested + mapped**. To re-run or extend:
|
||
```bash
|
||
python3 pipeline/gen_skins.py --local --dry-run # free: list the pack, no GPU
|
||
python3 pipeline/gen_skins.py --local # MODELBEAST flux2-klein-4b on MPS → .genraw/ (~5.7s/img)
|
||
python3 pipeline/gen_skins.py --harvest # → web/assets/gen/facade-*.jpg, then re-run build_manifest.py
|
||
```
|
||
`--local` drives `~/Documents/MODELBEAST/server/operators/flux_local/run.py` directly (no server,
|
||
no key, weights cached). It runs one GPU job at a time. Add skins by editing `PROMPTS` in
|
||
`gen_skins.py` and their shop-type map in `build_manifest.py` (`FACADE_TYPES`). **Always eyeball
|
||
`.genraw/` and delete rejects before `--harvest`.** Cloud fallback (drop `--local`): OpenRouter
|
||
`google/gemini-3.1-flash-image`, ~$0.004/img, needs `OPENROUTER_KEY`. Manual flow: `SKIN_PROMPTS.md`.
|
||
|
||
### 6. Bespoke hero props — `gen_props.py` (MODELBEAST) *(round-3: DONE, free, on-device)*
|
||
The `meshgod_batch.json` gap list now goes through MODELBEAST instead of fal.ai — free, local:
|
||
```bash
|
||
python3 pipeline/gen_props.py --dry-run # list props + what's done
|
||
python3 pipeline/gen_props.py --concepts # flux_local concept images → .genprops/*.png (eyeball!)
|
||
python3 pipeline/gen_props.py --mesh --only glass-case # trellis_mac 1024_cascade image→GLB (~5-8 min)
|
||
python3 pipeline/gen_props.py --mesh # all props with a concept, no glb
|
||
# then normalize (uses local Blender), stage, catalogue:
|
||
BL=/Applications/Blender.app/Contents/MacOS/Blender
|
||
"$BL" --background --python pipeline/normalize.py -- pipeline/batch_props.json pipeline/_normalized web/assets/thumbs
|
||
cp pipeline/_normalized/_results.json pipeline/_props_results.json && python3 pipeline/build_manifest.py
|
||
```
|
||
**5 shipped** (arcade_cabinet, listening_booth, drinks_fridge, milkshake_mixer, novelty_record) + cash-register
|
||
reused from depot. `magazine-rack` → primitive (thin-wire gotcha); `glass-case`/`bus-shelter` → fal.ai
|
||
fallback (TRELLIS can't do transparent glass; `sf3d --draft` gives a featureless blob). TRELLIS meshes run
|
||
heavy (25–77k tris) — see AUDIT provenance. **Eyeball every thumbnail**; ≤2 local attempts then fal (John's go).
|
||
|
||
### 7. Local-depot mode — `loaders.js ?localdepot=1` + `stage_local_depot.py` *(round-3: DONE)*
|
||
Lets Lanes B/C/F validate GLB loading with **no network / before publish**:
|
||
```bash
|
||
python3 pipeline/stage_local_depot.py # mirror _normalized/*.glb → web/assets/models/ (git-ignored)
|
||
# then load the game with ?localdepot=1 — depot:<file> resolves to assets/models/<file> instead of the CDN
|
||
```
|
||
|
||
### 8. Audio pack — `gen_audio.py` *(round-11: DONE, free, on-device)*
|
||
**Tool choice (Fable asked E to pick + document): pure procedural synthesis in numpy**, not a neural
|
||
model. MODELBEAST has no audio operator, and for this pack synthesis wins outright — $0, no model
|
||
download, deterministic/seeded (house law), **perfectly seamless loops** (neural gens don't loop),
|
||
**parody-safe by construction** (every sample is an original oscillator/noise render — nothing to
|
||
imitate), and precise ≤25 MB budget control. Pipeline: numpy synth → WAV → ffmpeg OGG/Opus (+ M4A/AAC).
|
||
```bash
|
||
PY=~/Documents/MODELBEAST/venvs/mflux/bin/python # numpy lives in the mflux venv
|
||
$PY pipeline/gen_audio.py --dry-run # list the 23-asset pack + budget
|
||
$PY pipeline/gen_audio.py # render all → web/assets/audio/*.ogg + *.m4a
|
||
$PY pipeline/gen_audio.py --only music # just the music beds
|
||
python3 pipeline/build_manifest.py # catalogue → manifest.json audio:{ambience,sfx,music}
|
||
```
|
||
23 assets, **8.1 MB** shipped (opus+aac): 6 ambience beds (street day/night, rain, 3 roomtones), 13
|
||
sfx (doorbell, door, till, riffle, toast, tram bell/rumble, 6 footsteps), 4 instrumental 90s music
|
||
loops. Loudness: beds/music `loudnorm` -16 LUFS, sfx peak-normalised. **Ear-ball** = spectrogram sheet
|
||
`docs/shots/laneE/audio_spectrograms.png` + numeric loop-seam/peak check (I can't subjectively listen —
|
||
final ear-check is John's/F's). Add assets by editing `PACK` in `gen_audio.py` + the `AUDIO_*` maps in
|
||
`build_manifest.py`. WAV scratch `pipeline/.genaudio/` is git-ignored; OGG/M4A ship committed.
|
||
|
||
## Cost summary
|
||
|
||
| step | cost |
|
||
|---|---|
|
||
| audit, normalize, manifest, validate, publish | **free** (compute + bandwidth) |
|
||
| facade skin gap-fill (23 imgs) | **free** — done on-device (MODELBEAST flux_local); cloud fallback ~9¢ |
|
||
| hero props (round-3) | **free** — 5 via MODELBEAST trellis_mac; glass-case/bus-shelter on fal.ai list (≤$2.70, John's go) |
|
||
| audio pack (round-11, 23 assets) | **free** — 100% procedural synthesis (numpy → ffmpeg), $0, no model |
|
||
|
||
## Artifacts (not committed — regenerated from the steps)
|
||
