Atelier · XI · Foundry of Voices

Purpose#

Audio atelier — "a reading, cast." Five-step workflow: voice cast → prosody- marked score → four takes → three stems (room/breath/bell) → mix to plate. Server-rendered by apps/oshun/web/src/app/atelier/audio/page.tsx via getAtelierAudio() → <AtelierAudio data>.

Entry points#

• Atelier index (/atelier) — second room card
• Lilith index (/lilith) — section VIII card 43 "XI · Foundry of Voices"
• Direct URL / bookmark — yes (signed-in)

Layout regions#

AtelierAudio (apps/oshun/web/src/components/lilith/atelier.tsx, line 558) renders inside LWebShell with LCustomerNav active="explore".

• Plate head (LAPlateHead no="XI"):
  • kicker: "The atelier · the foundry of voices"
  • title: A reading, <em>cast</em>.
  • right chips: "SN 22.59", "7 min · 04 takes", "Take 03 · kept" (accent)
• Three-column body (230px 1fr 320px):
  • Left rail (LAStepRail, current=3): five steps — "Voice · cast", "Score · prosody marked", "Takes · four", "Stems · room, breath, bell", "Mix · plate cut"
  • Center:
    • Score card (Score · with breath marks): three paragraphs with timecodes (00:00, 00:42, 02:14); pause marks ‖ (pause) / ‖‖ (long pause) / (•n) (breath, n seconds); legend at the bottom
    • Stems card (Stems · three layers): three rows from data.stems (each row = label + dB readout + procedural SVG waveform); playhead marker at 32%; timecode strip 0:00 / 02:14 · playhead / 07:00
    • Action row: "Re-cast voice", "Re-take §02:14", "Export · stems", "Mix · plate cut" (primary)
  • Right:
    • Voice · cast list from data.voiceCast (Sam Harris — kept, Tara Brach — alt candidate, J. Goldstein — alt canon, Lilith · house — synthetic disclosed); each row has a circular initial, name, attribution, role tag (accent for kept)
    • LRule
    • Take card · 03 with LField rows: Length 07:00, Bell "Tibetan · soft", Pacing "Slow · 124 wpm", Pauses "11 · breath-aligned", Emotion "Spacious, even", Synthetic "No · human voice"

States#

• Loading — server component awaits getAtelierAudio(); verify loading.tsx
• Populated — fixture provides 3 stems + 4 voice cast entries
• Synthetic voice disclosed — "Lilith · house" entry visibly marked Synthetic
• Kept take selected — Take 03 is accent; sample fields shown on right
• Error — verify error boundary
• Offline — static markup; renders offline
• Reduced motion — no animations declared

Interactions#

Score card#

• Score paragraphs — read-only typography with embedded pause glyphs and breath markers

Stems card#

• Stem rows (3, from data.stems: Voice · S. Harris (accent), Bell · Tibetan, Room · cream)
  • Read-only label + dB readout + procedural waveform SVG
• Playhead marker — visual only; no scrub interaction

Center actions#

• "Re-cast voice" button (ghost) — handler not present in static composition
• "Re-take §02:14" button (ghost)
• "Export · stems" button (ghost)
• "Mix · plate cut" button (primary)

Voice cast list (each row)#

• Sam Harris row (accent, "Narrator · kept" + 142 sittings)
• Tara Brach row ("Alt · candidate" + 96 sittings)
• J. Goldstein row ("Alt · canon" + 71 sittings)
• Lilith · house row ("Synthetic" + "Marked · synthetic, disclosed")
• Row tap behaviour — verify whether tap selects a different voice (no handler shown)

Data & contracts#

• Reads: getAtelierAudio() from apps/oshun/web/src/lib/lilith-data/atelier-depth.ts — returns AtelierAudioData with stems and voiceCast (planned BFF at /atelier/plates/audio)
• Writes: none in current static composition
• Realtime: none
• Caching: server fetch
• Auth/role check: middleware enforces signed-in

Cross-references#

• Atelier index: atelier.md
• Sibling rooms: atelier-image.md, atelier-video.md, atelier-forms.md, atelier-motion.md
• Downstream — AtelierMotion's "Compose · downstream" panel inherits "voice (foundry · take 03)"
• Component source: apps/oshun/web/src/components/lilith/atelier.tsx (AtelierAudio)
• Data: apps/oshun/web/src/lib/lilith-data/atelier-depth.ts

Open questions / known gaps#

• Confirm whether stems card supports playback / scrub interactions or is purely visual
• Verify synthetic-disclosure policy — the Lilith voice row is marked as synthetic, disclosed; cross-reference with Lilith policy on voice-quality and abuse policy (V1/features.md#lilith-persona-policy)
• Document where the SN 22.59 chip (top-right) maps to (a Nisaba sutta reference?)
