I built a synthesizer based on 3D physics

In plain words

Anukari 3D Physics Synthesizer is a virtual instrument that uses GPU-based audio processing to generate sound from three-dimensional physics simulations. It is designed for musicians and sound designers who want to create unique synthesized audio through interactive 3D manipulation. The software stands out for its novel approach to sound generation by combining physics modeling with real-time audio processing, developed as a nearly solo project over two years.

Build instruments from masses, springs and more in 3D space and hear what happens. A physics-powered synthesizer and effects plugin for VST3, AU, and AAX.

so i did a thing... I had this crazy idea: what if you could build instruments out of simulated physical masses and springs in 3D space, connect them, manipulate them, and just... hear what happens? meet Anukari. A software synthesizer and effects processor based on a fully interactive 3D physics simulation. Anukari is built entirely on real-time physics simulation. You can build structures that ring, vibrate, interact, and feed back into one another. Excite them with mallets, bows, your own audio, and more. And explore sonic palettes that are wildly out of this world. What does it sound like? Whatever you want. Sometimes it's subtle, and sometimes not so subtle. Does it create time…from anukari.com

In the maker’s words, at launch

I've been working on the Anukari 3D Physics Synthesizer for a little over two years now. It's one of the earliest virtual instruments to rely on the GPU for audio processing, which has been incredibly challenging and fun. In the end, predictably, the GUI for manipulating the 3D system actually ended up being a lot…

  Audiocube – A 3D DAW for Spatial Audio2025 · audiocube.app · ▲253

  I’ve recently released my solo project Audiocube I wanted to make a 3D DAW, where spatial audio, physics, and virtual acoustics are all directly integrated into the engine. This makes it easy to create music in 3D, and experiment with new techniques which aren’t possible in traditional DAWs and plugins. I’d love to get any feedback on this software (Mac/Windows) to make it better. You can download it for free through the website. Thanks, Noah

  Web Audio Spring-Mass Synthesis2025 · blog.cochlea.xyz · ▲77

  Hi, I'm the author of this little Web Audio toy which does physical modeling synthesis using a simple spring-mass system. My current area of research is in sparse, event-based encodings of musical audio (https://blog.cochlea.xyz/sparse-interpretable-audio-codec-pa...). I'm very interested in decomposing audio signals into a description of the "system" (e.g., room, instrument, vocal tract, etc.) and a sparse "control signal" which describes how and when energy is injected into that system. This toy was a great way to start learning about physical modeling synthesis, which seems…

  I made a volumetric audio visualizer2022 · a-sumo.github.io · ▲90

  I'm developing Hyperstep[0], a spatial language for music production. I find using existing DAWs frustrating because they don't allow me to navigate and operate intuitively on the latent spaces behind my musical ideas. This is why I've decided to build my own set of "seeing tools".(Bret Victor)[1]. I'm also convinced that by framing music as processes and interactions in the 3D world, spatialization and mixing should become fairly pain-free. I'm still early in development and I would love to build this into an actual product that can be integrated into existing DAWs or even turn it into a…

  Eigendrum - Draw any shape and hear what it sounds like as a drumAug 2026 · baselashraf81.github.io · ▲243

  Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

  What if your synthesizer was powered by APL (or a dumb K clone)?Mar 2026 · octetta.github.io · ▲92

  I built k-synth as an experiment to see if a minimalist, K-inspired array language could make sketching waveforms faster and more intuitive than traditional code. I’ve put together a web-based toolkit so you can try the syntax directly in the browser without having to touch a compiler: Live Toolkit: https:&#x2F;&#x2F;octetta.github.io&#x2F;k-synth&#x2F; If you visit the page, here is a quick path to an audio payoff: - Click "patches" and choose dm-bell.ks. - Click "run"—the notebook area will update. Click the waveform to hear the result. - Click the "->0" button below the waveform to copy…

  Koelsynth – a simple FM synthesis library2023 · github.com · ▲58

  This is part of my journey on pybind11. I wrote a tiny FM Synthesis library in C++ and a Python wrapper for that using pybind11. There is a command-line piano app in the examples directory if you want to play with it. Here is the link: https:&#x2F;&#x2F;github.com&#x2F;charstorm&#x2F;koelsynth&#x2F;tree&#x2F;main&#x2F;examples&#x2F;si... My next target is to attach this to some kind of physics simulation - like a bunch of balls moving around in a box with some internal walls. When the ball hits certain trigger points, it produces the sound.

  Tapflow 2.0▲1,125

  We built Tapflow for devs, designers, PMs, and tech folks who’ve been sitting on internal docs, templates, and systems — but never productized them. Upload a PDF, notes, or workshop deck, and Tapflow drafts a structured product (with chapters, teaser and pricing plans). It’s good for AI kits, onboarding guides, design systems, and frameworks. You can sell through Stripe, LemonSqueezy, or PayPal. Real-time collaboration is in early beta. No site builder, no LMS — clean design and just focused tools to ship. Fully bootstrapped and just launched on PH today →…
