1→# Worklog — AVA (Advanced Visualization Agent)
|
||
2→
|
||
3→Project: Audio-reactive visualization agent (AVS-style scripting, 3-band spectrum detection,
|
||
4→predictive beat tracking). Built as a Next.js 16 web app (reference implementation) plus a
|
||
5→Rust/Vulkan scaffold for the future native cross-platform export.
|
||
6→
|
||
7→User requirements:
|
||
8→- 3-band detection: Bass 20–100 Hz, Mid 700 Hz–2 kHz, High 7 kHz–16 kHz (user-adjustable)
|
||
9→- Beat detection from bass + beat PREDICTION (keeps beat when bass drops out)
|
||
10→- Green dot beat indicator + "Set Beat" tap-tempo button
|
||
11→- AVS-style custom visualization script editor: edit, save as default, save to file, load from file
|
||
12→- Help section with variables/functions reference
|
||
13→- 5 preset scripts (user provided real Winamp AVS presets on Google Drive)
|
||
14→- Rust + Vulkan target for Linux/Windows/macOS export (scaffold + blueprint delivered here)
|
||
15→
|

|
||
17→Task ID: 1
|
||
18→Agent: main (Z.ai Code)
|
||
19→Task: Project inspection + Google Drive preset retrieval
|
||
20→
|
||
21→Work Log:
|
||
22→- Verified dev server running on port 3000 (Next.js 16.1.3, dev.log clean)
|
||
23→- Fetched Google Drive folder (public) — extracted 5 file IDs and downloaded all files:
|
||
24→ - "Synth-C - Gap The Mind.avs" (12.5 KB)
|
||
25→ - "zamuz - wonder 'bout.avs" (34 KB)
|
||
26→ - "Synth-C - Quantization.avs" (14.8 KB)
|
||
27→ - "zamuz - keep tryin'.avs" (19 KB)
|
||
28→ - "zamuz - vorticity (brain activity remix).avs" (17 KB)
|
||
29→- Parsed binary AVS format (null-terminated strings): extracted Superscope code, Texer II
|
||
30→ configs, movement expressions. These are scene classics from visbot.net.
|
||
31→- Decided engine design: AVS-eel-flavored expression language (if/above/below/equal/rand,
|
||
32→ getspec/getosc-equivalents sv/v, reg-free flat variables) so the presets port naturally.
|
||
33→
|
||
34→Stage Summary:
|
||
35→- All 5 original presets secured and understood; will be adapted to the AVA script dialect
|
||
36→ (originals preserved as downloadable files in public/avs-originals/).
|
||
37→- Core engine architecture defined: expression compiler, script parser, BeatTracker (PLL-style
|
||
38→ predictor + tap tempo), AudioEngine (WebAudio FFT, mic/file/demo synth), canvas renderer.

43→Task: Project setup — deps, Prisma schema, DB, original preset files
|
||
44→
|
||
45→Work Log:
|
||
46→- Installed jszip (for the Rust scaffold zip download API)
|
||
47→- Prisma schema rewritten: `Preset` (name/author/description/content/isBuiltIn, unique name)
|
||
48→ and `Settings` (defaultScript + bandConfig + beatConfig JSON) — ran `bun run db:push` OK
|
||
49→- Copied the 5 original Winamp .avs binaries to public/avs-originals/ (downloadable from UI)
|
||
50→
|
||
51→Stage Summary:
|
||
52→- DB ready; jszip available; originals served at /avs-originals/*.avs

57→Task: AVA core engine libraries (src/lib/ava/*)
|
||
58→
|
||
59→Work Log:
|
||
60→- types.ts — BandConfig / BeatConfig / BandLevels / BeatFrame + defaults
|
||
61→ (bass 20–100 Hz, mid 700–2000 Hz, high 7000–16000 Hz as requested)
|
||
62→- expression.ts — full expression compiler: tokenizer → recursive-descent parser → closure
|
||
63→ tree. AVS-eel flavored: if() is LAZY, && / || short-circuit, ternary, ^ power (right-assoc),
|
||
64→ assignment valid inside call args + ternary branches (if(cond, x=1, x=2) works),
|
||
65→ newline & ';' statement separators (newlines inside parens ignored), '#'/'//' comments,
|
||
66→ deterministic hash rand(seed). 30+ functions incl. above/below/equal/band/bor/bnot/frac.
|
||
67→- script.ts — text format parser: header keys (name/author/description/mode/blend/persist/
|
||
68→ linewidth) + [init]/[frame]/[beat]/[point] sections, error objects with section+line,
|
||
69→ validateScript() never throws.
|
||
70→- beat.ts — BeatTracker: rolling-average energy detection w/ threshold+minInterval+floor,
|
||
71→ interval learning (median + EMA period lock, spread gating), PLL-style phase predictor that
|
||
72→ keeps firing beats when bass drops (confidence-gated, slowly decays), tap() tempo learning.
|
||
73→- audio.ts — AudioEngine: WebAudio AnalyserNode FFT 8192 (~5.4 Hz bins), byte-spectrum band
|
||
74→ averaging with attack 35ms / release 220ms smoothing; sources: demo (synthesized techno:
|
||
75→ kick 160→43Hz sweep, snare bandpass 1.8k, hats HP 8.2k, saw bassline — audible + analyzable),
|
||
76→ mic (never routed to speakers), file (loops, audible). getWave/getSpectrum for scripts.
|
||
77→- presets.ts — 5 built-in presets ADAPTED from the user's real AVS files:
|
||
78→ Gap The Mind (radial warp rings), wonder 'bout (bass-spawned expanding rings),
|
||
79→ Quantization (grid-snapped dot rings), keep tryin' (bass burst dots + swirl),
|
||
80→ vorticity (twisting spiral arms) + STARTER_TEMPLATE.
|
||
81→- engine.ts — AvaEngine: rAF loop (bands → beat → env → frame/beat progs → point prog ×N →
|
||
82→ draw), canvas 2d renderer with additive blending, per-point color, 2-pass glow,
|
||
83→ persistence trails, lines/dots/solid modes, DPR-aware resize via ResizeObserver,
|
||
84→ throttled stats callback for the UI. Singleton via getEngine().
|
||
85→- SMOKE TESTED via bun script: all 5 presets parse & execute 120 frames; lazy-if/ternary/pow
|
||
86→ OK; beat sim locks 124.1 BPM from 124 BPM kick train; predictor sustains beats through 10s
|
||
87→ of silence; tap tempo locks 120 BPM from 500ms taps. (2 parser bugs found & fixed: assignment
|
||
88→ inside call args; newline statement separators with paren-awareness.)
|
||
89→
|
||
90→Stage Summary:
|
||
91→- Core engine complete and verified. Env variables exposed to scripts: n, t, time, dt, frame,
|
||
92→ bass/mid/treb (+ _att), vol (+ _att), beat, bpm, beatphase, beatconf, beats, w, h, aspect,
|
||
93→ persist, i, v, sv, x, y, red, green, blue, skip, size, alpha.

|
||
103→- PUT/DELETE /api/presets/[id] — user presets only

117→Task: Complete UI for AVA — single-page app (dark club/VJ aesthetic) with header
|
||
118→(audio source controls, BPM readout, green beat dot + Set Beat pairing), visual
|
||
119→stage (canvas + engine loop), 5-tab control panel (Presets / Script / Detect /
|
||
120→Beat / Native) and sticky footer status bar.
|
||
121→
|
||
122→Work Log:
|
||
123→- Read worklog + all engine APIs (types/engine/script/presets/blueprint/audio/beat)
|
||
124→ and the existing API routes before writing any code.
|
||
125→- src/lib/store.ts — zustand store: throttled stats (AvaStats = EngineStats +
|
||
126→ beatCount), beatFlash pulses, bandConfig/beatConfig mirrors that write the
|
||
127→ engine live + persist (localStorage instant, PUT /api/settings debounced 600 ms
|
||
128→ with shape guards), preset list + refreshPresets(), script text, active tab.
|
||
129→- src/components/ava/audio-source.ts — tapBeat() (engine.beat.tap + dot flash +
|
||
130→ lastTap), applyScriptText() (validate → setScript, engine.setScript), and
|
||
131→ useAudioSource() hook wrapping startDemo/startMic/startFile/stop with error
|
||
132→ mapping (mic permission / no device / decode failure → destructive toast) and
|
||
133→ store sync from engine.audio.kind (authoritative).
|
||
134→- src/components/ava/beat-dot.tsx — the green indicator: SVG phase ring
|
||
135→ (stroke-dashoffset follows beat.phase, 150 ms linear transition), emerald dot
|
||
136→ that scales 1.9× + glows 180 ms on audio/tap beats, and for predicted beats an
|
||
137→ expanding outline ring (framer-motion, 450 ms) + "PRED" badge. Flash state is
|
||
138→ derived (seq vs clearedSeq) — no setState-in-effect.
|
||
139→- src/app/page.tsx — useInitialLoad (presets + settings; server → localStorage →
|
||
140→ first preset → STARTER_TEMPLATE fallback chain; applies configs + script),
|
||
141→ useBeatWatcher (see decisions below), useSpaceToTap (Space outside
|
||
142→ inputs/textarea/select/button → tap, preventDefault). Root layout:
|
||
143→ min-h-screen flex-col, lg:h-screen with internal panel scroll (footer always
|
||
144→ at viewport bottom; mobile pushes footer naturally).
|
||
145→- src/components/ava/header.tsx — sticky, backdrop-blur; emerald logo square +
|
||
146→ AVA title + subtitle (hidden on mobile); segmented Demo/Mic/File/Stop control
|
||
147→ (44 px targets, active state emerald, hidden file input); demo BPM slider
|
||
148→ (60–200, only while demo active); right cluster = BPM readout (mono, emerald,
|

149→ '—' when unknown) + BeatDot + Set Beat button, always visible, wraps to row 1
|
||
150→ on mobile (source controls wrap to row 2).
|
||
151→- src/components/ava/visual-stage.tsx — owns engine lifecycle (engine.start/
|
||
152→ stop + onStats → store), idle glass overlay with 3 big source buttons
|
||
153→ (AnimatePresence fade), top-left FPS/PTS readout (pointer-events-none), top-
|
||
154→ right fullscreen toggle (requestFullscreen on container). Canvas absolute
|
||
155→ fill; engine's ResizeObserver handles DPR.
|
||
156→- src/components/ava/presets-tab.tsx — preset cards (name/author/description
|
||
157→ line-clamp-3, mode + built-in/custom badges), Load (applies + toasts, jumps
|
||
158→ to Script tab on compile error), ".avs original" download link for built-ins
|
||
159→ via originalFileUrl(name), two-step Delete (3 s confirm timeout) for customs,

167→ mode: lines, n=480" (n from running [init] on a scratch env) / compile error
|
||
168→ / stats.error runtime errors.
|
||
169→- src/components/ava/help-panel.tsx — Quick Start, full variables table (frame
|
||
170→ + point-only), functions table, operators, 5 example formulas, .ava file
|
||
171→ format doc.
|
||
172→- src/components/ava/detect-tab.tsx — Bass/Mid/High cards: Low/High Hz sliders
|
||
173→ (bass 10–300/20–500, mid 100–5000/300–8000, high 1000–12000/4000–20000; low <

175→ readouts, live VU meters (instant fill emerald/amber/rose + _att peak-hold
|
||
176→ tick), per-band reset.
|
||
177→- src/components/ava/beat-tab.tsx — 80 px BeatDot + source badge (AUDIO/PRED/
|
||
178→ TAP), big BPM readout, large SET BEAT button (framer-motion whileTap), tap
|
||
179→ feedback ("Tap 3… keep tapping" → "Locked: 128.0 BPM"), confidence bar, beat
|
||
180→ count, sensitivity (threshold 1.1–2.5, "lower = more sensitive"), min
|
||
181→ interval 150–600 ms, prediction switch ("Keeps the beat alive when the bass
|
||
182→ drops out"), how-it-works explainer.
|
||
183→- src/components/ava/native-tab.tsx — renders BLUEPRINT (title/intro/sections/
|
||
184→ bullets/code blocks in scrollable pre), emerald "Download Rust Scaffold
|
||
185→ (.zip)" <a href="/api/rust-scaffold" download>, identical-language note.
|
||
186→- src/components/ava/footer-bar.tsx — sticky mt-auto status bar: SRC/FPS/PTS/
|
||
187→ BPM/SCRIPT micro-stats (mono), green "engine ok" / pulsing red "script error".
|
||
188→- src/app/layout.tsx — dark class on <html>, title "AVA — Advanced
|
||
189→ Visualization Agent", body bg-zinc-950.
|
||
190→- FIXED BUGS during browser testing: (1) Detect tab crashed — levels key for
|
||
191→ the high band is `treb` not `high` (added levelKey/attKey mapping to BandSpec);
|
||
192→ (2) lint: setState-in-effect in BeatDot (derived flash state instead);
|
||
193→ (3) lint: // text node in help panel.
|
||
194→- Tuned src/hooks/use-toast.ts: TOAST_LIMIT 1→3, TOAST_REMOVE_DELAY 100 s→5 s
|
||
195→ (lingering toasts were covering header/panel buttons during testing).
|
||
196→- VERIFIED in headless browser: initial load seeds presets + applies Gap The
|
||
197→ Mind (480 pts @60 fps); demo start/stop + DEMO slider; beat dot flashing live
|
||
198→ (scale 1↔1.9); tap tempo lock ("Locked: 119.9 BPM" from 4×500 ms taps, Space
|
||
199→ key too); after Stop the PRED badge/outline ring shows prediction carrying
|
||
200→ the beat; preset load/save/delete (two-step) round-trip via API; Save as
|
||
201→ Default → PUT /api/settings + localStorage; band slider → debounced PUT;
|
||
202→ .avs originals serve 200; script upload (auto-apply, n=300) + export to
|
||
203→ Upload Test.ava; mic error toast ("No microphone found" in this headless
|
||
204→ env); no blue/indigo anywhere; lint clean; tsc clean for owned files.
|
||
205→
|
||
206→Stage Summary:
|
||
207→- Files created: src/lib/store.ts; src/components/ava/{shared.ts, audio-source.ts,
|
||
208→ beat-dot.tsx, header.tsx, visual-stage.tsx, presets-tab.tsx, script-tab.tsx,
|
||
209→ help-panel.tsx, detect-tab.tsx, beat-tab.tsx, native-tab.tsx, footer-bar.tsx,
|
||
210→ control-panel.tsx}. Modified: src/app/page.tsx (replaced), src/app/layout.tsx,
|
||
211→ src/hooks/use-toast.ts (toast duration/limit only).
|
||
212→- KEY DECISION — beat flash sampling: engine stats are throttled (~8 Hz) but
|
||
213→ beat=true lasts one frame, so most beats are invisible in stats. The watcher
|
||
214→ in page.tsx ALSO fires on beat.phase running backwards (real beats reset
|
||
215→ phase to 0; the predictor grid wraps at 1). Classification: stats.beat.beat
|
||
216→ sampled → exact source; phase drop + prediction on + confidence > 0.35 +
|
||
217→ bassAtt < 0.06 → 'predicted'; phase drop + bassAtt > 0.05 → 'audio'; silent
|
||
218→ no-lock → no flash (idle dot doesn't pulse). Tap flashes suppressed for
|
||
219→ 300 ms to avoid double pulses. Verified working in-browser.
|
||
220→- KEY DECISION — desktop uses lg:h-screen + internal panel scroll so the footer
|
||
221→ stays at the viewport bottom and the canvas fills the height; mobile uses
|
||
222→ natural flow (min-h-screen + mt-auto footer) so the footer is pushed down.
|
||
223→- Store is the only place configs touch the engine (applyBandConfig/
|
||
224→ setBandValue etc.), keeping live-update + persistence consistent everywhere.
|
||
225→- NOTE for Task 5 (integration): /api/rust-scaffold is linked from the Native
|
||
226→ tab but the route does not exist yet (Task 3-b owns it — expect 404 until
|
||
227→ then). BLUEPRINT is still the stub; the Native tab renders whatever 3-b puts
|
||
228→ in it, no UI changes needed. Settings row 'main' currently holds
|
||
229→ defaultScript="Gap The Mind" + default bandConfig from testing (both equal
|
||
230→ defaults — safe to leave or clear). Pre-existing tsc errors in
|
||
231→ src/lib/ava/{audio,script}.ts and examples/ are NOT from this task
|
||
232→ (ignoreBuildErrors is set).

252→- src/render/{mod.rs,shader.wgsl} — wgpu pipelines: audio-reactive fullscreen background +
|
||
253→ additive point cloud, #[repr(C)] uniforms, persistence via TODO'd feedback texture
|
||
254→- presets/*.ava — all six scripts (5 classics + starter) portable across engines
|

358→ within the 5-minute budget — still blocked. Surfaces as a clean 422 with the sanitized tail:
|
||
359→ "Could not extract audio from that link: …Sign in to confirm you're not a bot…". Honest
|
||
360→ outcome: blocked here, ACCEPTABLE per spec (would work from residential IPs / with cookies).
|
||
361→- Test 4 SoundCloud forss/flickermood: yt-dlp extracts fine (title "Flickermood", 213.9 s) but
|
||
362→ this serve only exposes m3u8_native formats (hls_aac_96k/160k — confirmed in raw -J JSON) →

365→ or a direct MP3 link."; example.com/stream.m3u8 → 422 (does NOT hit the direct bypass).

|

370→ (missing file) → 502 "Upstream failed (HTTP 500)."
|
||
371→- lint: my 4 files pass eslint clean; `bun run lint` overall reports exactly 1 remaining error in
|
||
372→ src/components/ava/link-dialog.tsx:72 (set-state-in-effect) — that file is owned by the parallel
|
||
373→ frontend agent and was NOT touched by me per the ownership rules.

374→- dev.log: no exceptions/stack traces from the new routes — only expected
|
||
375→ 200/206/400/404/422/502 request lines.
|
||
376→- Deviations from spec (all deliberate): (1) one network-error retry in the proxy (upstream RSTs,
|
||
377→ never retries HTTP statuses); (2) third store helper refreshStreamEntry() — the two required
|
||
378→ helpers plus this one implements the specified "refresh sliding expiry AFTER upstream success";
|
||
379→ (3) proxy fetch uses cache:'no-store'; (4) 500 wording "Audio extractor unavailable (yt-dlp not
|
||
380→ found or failed to start)."; (5) success cache keyed by the normalized URL href (target.href).

|
||
390→- src/lib/ava/types.ts — AudioSourceKind += 'link'
|

391→- src/lib/ava/audio.ts — new startUrl(streamUrl, title): same-origin proxied <audio> element →
|
||
392→ MediaElementAudioSourceNode → analyser (NOT cross-origin-tainted, so FFT works) → speakers;
|
||
393→ loops by default; public sourceLabel field (file name / stream title) maintained by all
|
||
394→ start* methods + stopSources
|
||
395→- src/lib/store.ts — AudioSourceState += 'link'; new sourceTitle + linkDialogOpen state
|
||
396→- src/components/ava/audio-source.ts — new resolveAndPlayLink(url): POST /api/resolve →
|
||
397→ engine.audio.startUrl → store sync; never throws (returns {ok,title,source,error}); on
|
||
398→ playback failure stops the engine and resets store; syncSource now also syncs sourceTitle
|
||
399→- src/components/ava/link-dialog.tsx — NEW: dialog with URL input + Load button (spinner),
|
||
400→ inline error box with YouTube bot-wall hint, RECENT LINKS chips (localStorage, max 5,
|
||
401→ one-click reload); body REMOUNTS on every open (fresh state — no setState-in-effect, fixes
|
||
402→ the lint error the Task 6 agent saw mid-build); results arriving after the user closed the
|
||
403→ dialog surface as toasts

404→- src/components/ava/header.tsx — "Link" segment button between File and Stop (opens dialog);
|
||
405→ <LinkDialog /> mounted in the header
|
||
406→- src/components/ava/visual-stage.tsx — idle overlay gains a 4th button "Stream a Link" +
|
||
407→ updated copy
|
||
408→- src/components/ava/footer-bar.tsx — SRC now shows "LINK · <title>" (truncated) for the
|
||
409→ active source; title also shown for File sources
|
||
410→- src/app/api/resolve/route.ts (main-agent touch-up, coordinated with Task 6's file): added
|
||
411→ BOT_WALL_RE mapping so YouTube's "Sign in to confirm you're not a bot" stderr returns a
|
||
412→ clean actionable 422 instead of a raw yt-dlp tail; client hint suppressed when the server
|

413→ message already explains the fix (no duplication)
