15→ 15→// 7.14 — Arctic Rainbow re-imagined (user request): the old stand-in was

16→ 16→// plain white columns of rain dots sweeping upward. Rebuilt as a
|
||
17→ 17→// music-driven water spray, stateless projectile physics in the
|

18→ 18→// [point] program: each of up to 120 droplets is a deterministic

19→ 19→// parabola (own apex height 1.26..1.88, own flight time 1.9..3.4 s,
|
||
20→ 20→// phase-staggered clock; every splash cycle re-rolls its origin,
|

22→ 22→// hang, arch left or right, fall back off-screen. Drop count

24→ 24→// slow release 1.2/s: silence = 0 drops, loud = all 120). Each
|
||
25→ 25→// drop owns a hue that shifts by its own per-drop amount on every

26→ 26→// detected beat, plus a subtle gradient along its tail. The tail

28→ 28→// drawn as a tapered polyline in lines mode, gated by smoothstep

38→ 38→// INCLUSIVE (classic AVS Superscope convention, engine.ts: i =

248→ 248→// Improved / Fixed / Removed notes (src/lib/release-notes.ts,

249→ 249→// color-coded tags, the running version badged "current",

254→ 254→// release note; a dev-mode guard warns when they drift
|
||
255→ 255→// 7.5.1 — Link dialog width fix: text no longer escapes the dialog box.
|
||
256→ 256→// Root cause: Radix dialogs lay their children in an implicit CSS
|
||
257→ 257→// grid whose single column sizes to the widest child's min-content;
|
||
258→ 258→// the RECENT LINKS rows carry truncate spans (white-space: nowrap),
|
||
259→ 259→// and Chromium measures a nowrap flex item's full text width for
|
||
260→ 260→// that measurement — so a long saved title (e.g. "Bobby Foxx — This
|
||
261→ 261→// Is Why We Can't Have Nice Things (Official Music Video)") blew
|
||
262→ 262→// the column ~40 px past the 448 px dialog, and EVERY child (title,
|
||
263→ 263→// description, input + Load, rows, footer) laid out beyond the
|
||
264→ 264→// right border. Fix: the shared Dialog/AlertDialog content now pins
|
||
265→ 265→// the column to minmax(0,1fr) — capped at the available width, so
|
||
266→ 266→// no nowrap content can ever stretch a dialog again (covers every
|
||
267→ 267→// dialog app-wide) — the Link dialog widened to max-w-lg for
|
||
268→ 268→// comfier wrapping, and min-w-0 + break-words added on the
|
||
269→ 269→// recents/playlist containers and error text as belt-and-braces
|
||
270→ 270→// 7.5 — yt-dlp compatibility: single tracks resolve by DOWNLOAD + CONVERT
|
||
271→ 271→// instead of proxying the extractor's stream URL. The old stream
|
||
272→ 272→// URLs were IP-locked (googlevideo bakes in the resolver's IP),
|
||
273→ 273→// expired within hours, and arrived as webm/opus — a container
|
||
274→ 274→// Safari & co. refuse ("The media resource … was not suitable").
|
||
275→ 275→// The server now runs the operator's pipeline per track:
|
||
276→ 276→// yt-dlp -f bestaudio/best -x --audio-format mp3
|
||
277→ 277→// --audio-quality 0 -o "<dir>/%(title)s.%(ext)s" URL
|
||
278→ 278→// — audio-only download, universal MP3 at VBR-0 (~245 kbps), the
|
||
279→ 279→// video's real title preserved for the Playing: label. The
|
||
280→ 280→// finished file streams same-origin with full Range support from
|
||
281→ 281→// a per-track workspace dir (30-min sliding TTL + orphan sweeper);
|
||
282→ 282→// /api/audio/stream gained a file-serving mode. Hardening around
|
||
283→ 283→// it: shared failure classifier for both yt-dlp passes (metadata +
|
||
284→ 284→// download), 180 s download budget, 300 MB cap, bot-wall/stale-
|
||
285→ 285→// extractor answers unchanged, ffmpeg-missing degrades to the old
|
||
286→ 286→// proxy path (logged once), queue look-ahead lead 15 s → 60 s so
|
||
287→ 287→// playlist transitions don't stall behind conversions
|
||
288→ 288→// 7.4 — Sequence mode: a second mix checkbox next to Random. Ticked, it
|
||
289→ 289→// cycles the scope folder's presets IN ORDER (the tree's exact
|
||
290→ 290→// top-to-bottom order) instead of shuffling — and when it moves
|
||
291→ 291→// past the last preset it wraps back to the first, so the folder
|
||
292→ 292→// loops forever. Random and Sequence are mutually exclusive
|
||
293→ 293→// (ticking either one unticks the other; both share the same
|
||
294→ 294→// delay and folder scope), Random now never loads the same preset
|
||
295→ 295→// twice in a row, and Sequence holds its breath through silence
|
||
296→ 296→// exactly like Random does. The Demo showcase now runs SEQUENCE —
|
||
297→ 297→// the one play-through walks every Zai-Magic preset in order
|
||
298→ 298→// (20 s each) rather than repeating random picks, and when the
|
||
299→ 299→// demo stops, whichever mode it checked is unchecked again
|
||
300→ 300→// 7.3 — demo-flow refinements: the Demo Track is a single pass — it plays
|
||
301→ 301→// "Neural Mecha Pulse" once through and stops (a demo, not a radio
|
||
302→ 302→// station). However it ends (natural finish, Stop, or switching to
|
||
303→ 303→// another source) the showcase unwinds: the randomizer the Demo
|
||
304→ 304→// flow force-checked is unchecked again, and the visitor lands
|
||
305→ 305→// back on the "Select an audio source" overlay. Preset-change
|
||
306→ 306→// popups are gone ("Preset loaded" / "Random preset" / "Default
|
||
307→ 307→// preset running") — the footer's SCRIPT: label already echoes
|
||
308→ 308→// every change, so the toasts were pure intrusion; only compile
|
||
309→ 309→// errors still toast. Club-mode randomizer now respects silence:
|
||
310→ 310→// when no music is playing it never re-shuffles the selected
|
||
311→ 311→// preset, even with the checkbox on — it waits for the next track
|
||
312→ 312→// 7.2.1 — Supernova (Zai-Magic) preset fix: the particle kill condition
|
||
313→ 313→// (|px|+|py| > 2.4) was physically unreachable — drag caps a
|
||
314→ 314→// particle's total travel at vel/1.6 ≈ 1.0, so nothing ever
|
||
315→ 315→// crossed 1.4, nothing ever died, and since respawning requires a
|
||
316→ 316→// dead particle, the per-beat "budget = n" detonation could never
|
||
317→ 317→// fire after the initial one — the preset exploded once on load,
|
||
318→ 318→// then faded to permanent black. Now every beat force-clears the
|
||
319→ 319→// whole 620-particle field in [beat] (guaranteed full re-detonation
|
||
320→ 320→// on the very same frame), fully-cooled particles die by fade so
|
||
321→ 321→// long beat gaps leave a gentle ember drizzle instead of black,
|
||
322→ 322→// and each blast re-randomizes its geometry (no two explosions
|
||
323→ 323→// alike). Embedded library re-seeded (seed marker 7.01)
|
||
324→ 324→// 7.2 — new-visitor showcase flow. Defaults for first-time visitors:
|
||
325→ 325→// the Black + Purple Outline theme with the Blue highlight
|
||
326→ 326→// (previously royal purple + yellow), and Zai-Magic "Bass Bloom"
|
||
327→ 327→// as the startup preset (previously the first Synth-C classic).
|
||
328→ 328→// The idle overlay's Demo Track button now carries an animated
|
||
329→ 329→// reflective shimmer (skewed light band sweeping left→right every
|
||
330→ 330→// 3.2 s, reduced-motion safe) to draw the click — and that one
|
||
331→ 331→// click starts the full showcase: the demo track plays while the
|
||
332→ 332→// preset tree selects + expands Zai-Magic, randomize switches on
|
||
333→ 333→// scoped to that folder with a 20-second change interval. Music
|
||
334→ 334→// started with NO preset active (own draft running / selection
|
||
335→ 335→// cleared) auto-loads Bass Bloom. Preset changes — manual load,
|
||
336→ 336→// the random mix, the Demo flow — no longer hard-cut: the engine
|
||
337→ 337→// snapshots the outgoing frame and blur-dissolves it into the new
|
||
338→ 338→// preset over 700 ms (progressive blur + easeOutCubic fade + a
|
||
339→ 339→// slight scale-up so the softening edges never gap; plain
|
||
340→ 340→// crossfade where ctx.filter is unsupported)
|
||
341→ 341→// 7.1 — real demo track + a beat detector that survives real music.
|
||
342→ 342→// The Demo button now plays "Neural Mecha Pulse" (the operator's
|
||
343→ 343→// mastered industrial-EDM banger, public/demo-track.mp3, loops
|
||
344→ 344→// gaplessly) instead of the synthetic techno pattern — a real
|
||
345→ 345→// recording is the honest test: deep sub for the bass bands,
|
||
346→ 346→// driving mids, crisp highs, and a kick buried in sustained
|
||
347→ 347→// sub-bass. That last part exposed the 6.x detector as fundamentally
|
||
348→ 348→// broken on mastered music: a LEVEL threshold can never see the
|
||
349→ 349→// kick through the sub (peak-to-mean caps at ~1.2× → sporadic
|
||
350→ 350→// fires, phantom 120-BPM locks from the minInterval floor).
|
||
351→ 351→// v7.1 rewrites detection the way real beat trackers work
|
||
352→ 352→// (aubio/librosa-style): a full-band spectral-flux ONSET envelope
|
||
353→ 353→// → autocorrelation over 300–1000 ms lags with a log-BPM prior →
|
||
354→ 354→// comb-filter phase with grid hysteresis → beats fired on an
|
||
355→ 355→// absolute grid kept glued by a PLL pull. Headlessly validated
|
||
356→ 356→// against the actual track PCM (AnalyserNode chain replicated
|
||
357→ 357→// frame-for-frame): locks the true ~133 BPM (the song drifts
|
||
358→ 358→// 130.7→133.1 — the grid TRACKS it) in 1.9 s, 92% beat-gap
|
||
359→ 359→// regularity, confidence 0.99 through the body; techno/hip-hop
|
||
360→ 360→// patterns lock exactly; silence yields zero beats. Known limit:
|
||
361→ 361→// sparse kick-vs-snare backbeats (dnb) may lock half-tempo —
|
||
362→ 362→// stable, and two taps of Set Beat correct it. Visitor-stored
|
||
363→ 363→// beat configs migrate (floorLevel changed units, level → flux).
|
||
364→ 364→// The demo BPM slider is gone (a real track's tempo is detected,

373→ 373→// plus new script-language features is a major release; 6.9.3 was

378→ 378→// C3+ with a sidechain pump — chronological envelope events!),

379→ 379→// and the detector's default threshold 1.4 → 1.2 (the 170 ms FFT

380→ 380→// window caps a clean kick's peak-to-mean at ~1.5×, so 1.4 fired
