  Im building some music playback software and am currently struggling with the implementation of a spectrum analyzer to visualize the music.This is incredible stuff and I learned a lot. Well done sir.Ps, also mourning the loss of Fable! It sorted out a 3 month bug hunt odyssey in 3 days. For a somewhat novel problem in a pretty niche area (DSD DoP audio crackle problems during certain playback edge cases).

  > As we all know, the foundation of Western diatonic music theory is ¹²√2, the ratio between the frequencies of successive semitones.Nods knowingly. Yes, of course. I definitely know this.

  I was not expecting the part where Fable produces a passable 3Blue1Brown-style explainer video of the algorithms it just implemented that sounds like it's narrated by a character from Dora the Explorer.What a strange era we now live in.

  That was my experience with Fable as well. Pulled my extremely complex project that I could squint and see was possible, but actually put mathematical concreteness to things in a way I could only intuit.On the flip side, visualizers have always fascinated me. I love this one, but one build off I've always wanted to see: analyze the entire file a priori, and then generate the visuals. Sort of like a normalization pass, but getting longer form structures decoded ahead of time could be pretty neat.

  My Fable example is not nearly as cool but still (to me) impressive.Last year, I would occasionally test the latest models by vibe-coding in-browser music generators using only HTML, CSS, and JS. Here’s one made in July by Gemini:https://gally.net/temp/20250701synthesizer-gemini2/index.htm...And one made in September by Claude:https://gally.net/temp/20250917rhythmdrone/index.htmlWith Fable, I was able to one-shot something much more sophisticated:https://gally.net/temp/20260610-fable-synthesizer/index.htmlIt’s still a long way from creating music I would want to listen to, though.

  That generated video was eye opening for me. I've been using Opus in Claude Code for studying and at work, but it never occurred to me to use 3b1b's excellent python library for generating maths visualisations to let it generate such good graphical demonstrations.

  This is amazing.One of the weaknesses of the video is that there are artifacts in the narration of passing through a text layer. "Bass" is pronounced as the fish at one point. "Wound" is pronounced as the injury. It's clear that these are homonyms of what was actually intended by the script.

  > This model doesn't shy away from drawing upon all its knowledge. It casually refers to alpha premultiplication and fundamental frequencies in the same breath. It is fond of acronyms.Yes - I had Fable tackle some long-standing bugs in some code I had and I quickly lost track of what it was talking about and had to ask a lot of clarifying questions.It killed my bugs like they were nothing though. Opus and even GPT5.5 had churned on these same things for ages, but even with my manual help we made no progress.It felt like they weren't the slightest bit challenging for Fable. So glad to see it back!

  >The writing is also literary. It draws an analogy between the 12 musical pitch classes and the 12 markings on a clock. Noise lingers. Material surges off the rim.I absolutely hate this revolting writing style by LLMs

  This was really cool. I would love to play some Dave Tipper on this to see what it looks like.

  Kinda interesting how its just like a FFT chart in a circle but perhaps the author is not aware that is the case. Would be curious to know what things were "implmentation details" for the fancy AI and what wasn't.I could be wrong but milkdrop already would do light FFT analysis for effects right?

  Very, very cool.

  That Fable Generated video is something else... wow I love it.. along with the appAnyone who says LLMs can't reproduce intelligence I mean really? can you make this? its not just a talking database guys or a stochastic parrot...too bad Fable was nerfed/gatekept by the Trump corruption selection committee..but the technology will not be silenced.. we just need to get humans ready for this capabilities. the jury is out on the future of that.

  > steady stream of promotions until they cap out at L5Am I missing a joke? L5 is just a single promotion away from hiring-out-of-college, at least for the FAANG that I was at.

  Thought this might be about the video game series, and even after seeing "Fable 5" my first reaction was "wow, up to 5 already?". It looks like they made it up to Fable III before rebooting the series with a 4th game (well, it's not out yet), so there is no Fable 5 yet.TFA seems to be about some AI thing. Crazy how many words are actually just AI things now. Learning, reinforcement, language, model...
