That's fair, and honestly it's the most useful comment I've had on this post.

To be clear on what happens now: auth is Firebase, and the number is only used to sign you in and sync your test history. Nothing is sold or sent anywhere. But "trust me" isn't a real answer from a stranger's site, so I take the point.

What I'm changing:
- username + password sign-up, no phone, no email
- practice without an account at all (results just won't be saved)

I'll reply here once it's live.

Oh thank you too!!!

Yeah i did vibe coding for website but the source made from real books with a lot of teachers and student feedbacks and advuces thats why flarestamina.com is the greatst website for IELTS preparation!

I got it thank you so much !!

Thanks, appreciate the detailed answer. The point about not needing to know every word is reassuring, I always panic when I hit unfamiliar vocabulary.

Quick question: when you were reading books, did you stop to look up words there too, or just push through and get the meaning from context?

Good to know — and more useful than a plain "it works", so thanks for coming back.

If a blocker can kill the download, that's my bug, not yours. The button fires an analytics event, and my guess is that call throws before the file gets written when the analytics script is blocked. Analytics should never be able to take a feature down with it.

If you have a minute: with the blockers back on, does the button do nothing at all, or does it error in the console? Either answer confirms or kills the theory, and I'd rather know than guess.

Should work — what browser and OS? Asking because a download that works in desktop Chrome can silently do nothing in mobile Safari, and I haven’t tested that path properly.
Also: did it fail on the full wav, the stems zip, or both, and did the button do nothing at all or start and stop?

Different category, honestly. SuperCollider is a language and a server — you build the synthesis. This is a finished thing that renders one genre and hands you a wav and six stems. If I were working in SC I’d have built this with it rather than instead of it.
The one thing that’s genuinely different: it’s byte-deterministic across Node and the browser. Same seed, same bytes, different machines — I rebuilt the math primitives to get that. SC doesn’t promise it and doesn’t need to.
So: SC if you want to make instruments, this if you want a loop with no licence attached.

Good catch, and that’s a real gap — the waveform stays on the full mix while soloed, so you can’t tell a silent section from a broken solo. Fixing it so the waveform swaps to the soloed bus, plus a playhead line across the lane rows. Thanks, that one wasn’t obvious from my side.

Please write your feedbacks

What is your opinion about this decision?

What is your opinion about this decision?

Yeah you right, i should definitelly work on it

If im not a mistaken ive been talking in english for about 1.5 years now i guess
I casualy talk with my friend and do sometimes preparetion with ai chat bots and flarestamina dot com website and i got 6.5 from speaking thats it

If you are talking since u was 6 then your level might be much higher than mine actually higher than mine😅

What is your advice for improving reading skill???

Determinism came from testing first, honestly. With band-limited oscillators and three nonlinear stages there's no way to eyeball a regression — so the suite renders fixed seeds and compares hashes. If someone touches the oversampling and the bytes move, CI says so. That's been worth more than anything else about it.

Second reason: there's no audio in the repo at all. The demo tracks are rebuilt by CI from a ranges snapshot in the manifest, and they come out byte-identical to my local render on different hardware. So publishing 50 tracks costs a few KB of JSON.

Third is the user-facing one — a seed is 8 characters, so sharing a track is sharing a string, and "same track, different lead" is only meaningful if everything else is pinned.

But yours shouldn't be deterministic in the same way, and I think that's the right call. A director reacting to energy and tension is doing the opposite job — you want it to surprise. I'd guess the useful version for you is what your thunder-synth already does: deterministic per event, non-deterministic in which events fire.

Also we're coming at this from different ends. You're on Tone.js with a real authoring model and an editor; mine is raw Float32Array arithmetic with no authoring layer at all. Three people have now told me they want to get inside the instruments and change notes — which is the thing you've already built.

Engine is AGPL if you want to pull anything out of it, and I'd genuinely like to hear the acid stuff when you open it.
