Koelsynth – a simple FM synthesis library

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://github.com/charstorm/koelsynth/tree/main/examples/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.

Koelsynth – a simple FM synthesis library launched on November 11, 2023 with 58 votes, #1,147 of 4,333 launches that month and more than 90% of that year's launches. The site was still online in September 2026, 2 years on.

In plain words

Koelsynth is a lightweight FM synthesis library written in C++ with a Python wrapper built using pybind11. It includes a command-line piano application for experimentation. The library enables sound generation through frequency modulation synthesis and is designed for integration with physics simulations, allowing audio to be triggered by collisions or events within virtual environments.

  • I built a synthesizer based on 3D physics2025 · anukari.com · ▲512

    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 more work than the physics simulation. So far I am only selling it direct on my website, which seems to be working well. I hope to turn it into a sustainable business, and ideally I'd have enough revenue to hire folks to help with it. So far it's been 99% a solo project, with…

  • 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://octetta.github.io/k-synth/ 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…

If not, check my project :) Here is how it looks: SELECT mono(output( arraySum(x -> 1 / 6 * running_envelope(30 * (1 + x / 6), time, 0.05 * x, 0.005, lfo(0, 0.25, sine_wave, time / 8), 0.1) * sine_wave(time * 80 * exp2(x / 3)), range(12)))) FROM table; To check how it sounds, find the examples in the repository https://github.com/ClickHouse/NoiSQL

    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…

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  • Hi HN, I’m Kashish, one of the co-founders of SpeedVitals, a platform for testing & monitoring website performance with a major emphasis on Core Web Vitals. Until now, our platform has only focused on Synthetic/Lab testing, such as Lighthouse tests and TTFB tests. But now, we have developed a Real-User Monitoring platform that doubles up as a Web Analytics tool. One major feature we have that most RUM tools lack is Performance Audits. Just like Lighthouse audits work on Lab test data, our audits work across all the real-user visits and gives suggestions on what task to prioritize first.…
