  • 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.

  • 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?

  • 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:

    And one made in September by Claude:

    With Fable, I was able to one-shot something much more sophisticated:

    It’s still a long way from creating music I would want to listen to, though.

  • 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.

  • 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).

  • 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.

  • > 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.
