Products that do what Web-REPL "skred" : my OSS sound engine w/retro C64 appearance does
I've been working on a C-based open source sound engine as part of a book project and wanted an approachable way for people to try it out without having to build anything. Through the magic of emscripten (which I'm totally amazed by) and miniaudio (which has given me new life late in my development career), and a smidge of vibe-coded HTML/JS (web-dev is not my jam), this page will let you try out the tooling. I gave a lightning talk on the ASCII notation at ElixirConf EU last month here: https://www.youtube.com/watch?v=SnJ0osgiqWM There's a work-in-progress tutorial for…

So, I've never written a line of Rust in my life. I wouldn't know an `&mut this` from a mutandis. But I saw a tweet about a month ago that said, in this new era of AI, you'd be able to just take a library that you love, throw a TUI around it, and call it an app. So I spent about 200 bucks last month, here's what I came up with: Imbolc is a DAW that runs entirely in your terminal. It talks to scsynth over OSC and ships 58 instruments and 39 effects. VSTs are a work in progress, also GarageBand loops if you want to recreate "Umbrella". The codebase is about 60k? lines of Rust across 5 crates,…

Inspired by the recent Boards Of Canada announcement, I've been in a low-fi electronica mood lately and was going back and forth with Claude on how to design similar instruments in the browser that fit the genre. One thing led to another and pretty soon I had a fully browser based polyphonic synthesizer / drum machine / sequencer. The interface and workflow was heavily inspired by the Rebirth338 application released back in the 90's, but with lo-fi synth voices rather than the original 303 & 808 emulation. I know there's a significant overlap of developers and musicians and I…

Hey HN! Last week I was working on a website and needed a way to synchronise visuals with live music. I've used MIDI controllers for this before, but I am travelling right now and don't have mine with me. So I had the crazy idea to build a browser extension that uses the keyboard as input and includes a sequencer. I gave myself 24 to work on it. It ended up taking longer (of course), specially since I ended up creating a demo, a small landing, docs, and an intro video. Took me one week from idea to launch (pushed quite a bit tbh). Features: - Works as a browser extension. Atm distributed…

Hi - I'm part composer, part engineer and big fan of reading blogs where people learn out loud or with the garage door up by sharing their notebooks or journals. I've been doing this in Moleskines for years (going back to the 80s) but made it a new year's in 2024 resolution to post SOMETHING everyday, so long as I created the sound. I have a big archive of demos and seeds of ideas, so I figured it wouldn't hurt to do something with those in the process. Being so steeped in programming for the last 30 years, a healty chunk of this material is made via coding with Csound, TidalCycles, some raw…

Hey y'all, So - the main idea of this is to make a WebAudio synthesis/sequencer tool which humans can use via the UI, but where the big unlock is for agents to drive with MCP It's semi decent as "make a groovy jazz track", especially for retro sounds - but the real use case is more like "make a jetpack whoosh effect I can control via code at runtime - where the sound changes based on character health or how much fuel is left" In other words, the target audience is not musicians (except maybe of the Max/MSP sort), but more like creative coders who want to shape the sound iteratively…

Hey gang, My names Ryan. I Develop Desktop applications, usually for Windows. I made this little Trainer application , if anyone wants to try it out. It lets you manipulate values in memory, in-order to hack stats, crafting materials, etc. If you like it, have any suggestions, or angrily yell about the console release, feel free to hmu. https://github.com/howzitkiffen/Cyber-Punk-Trainer (PS: Looking for work!)

Try it at: ssh krnl.duetbrowser.com No sign up, totally free - no download. Let me know what you think. Prior art exists (brow.sh) but I wasn't satisfied with their graphical take. I wanted the raw, old skool terminal days of the early internet - BBS, and old green phosphor library comptuers - but running the modern web, with all the bells and jingle jangle whistles (JavaScript, etc). No funding, no VC, just 100% raw terminal fun. Not sure how long the demo will last, but try it out.

Hey HN, I built a website where you can train Llama 3.1 8b & 70b (4bit) on your data. I use unsloth in the backend and the training is done on H100s which I rent programmatically from Runpod. I'd love some feedback. If you would be interested in using it feel free to book a chat with me: cal.com/hamada/tunellama-intro Happy to give you free credits :) P.S. I'm also looking for a co-founder as I have big plans for this.

I spent the past few weeks making an open source cloud code editing environment with an AI copilot and multiplayer collaboration! It's fully self-hostable in 5-10 minutes. There's a lot of minor improvements to be made, and some are already listed in the Github issues. Let me know what you think and feel free to try it out.

A buddy and I decided to hack on this little project this weekend, putting in about 12 hours. It's running Ruby on Rails, deployed to Heroku. We tried to keep things super lean with different gems handling user accounts, mailchimp for an email list and super lean styling/layout. Everything should work well enough on mobile devices, too, so give it a look! Right now the magic all happens via the Soundcloud API (of course), but we're exploring different ways to make this appeal to a broader audience of music listeners. We'd love your feedback! Here's the site:…

Hey all. For the last few years, I have been developing a software synthesizer as a side project. It's taken longer than I both hoped and feared, but earlier this week I finally shipped 1.0. Details about the synth itself are up on my website, https://lhiaudio.com/. For those who are unfamiliar, in music production, there are host applications (such as Logic Pro, Ableton Live, or REAPER) in which most of the work (such as recording or sequencing MIDI data) is done. These applications generally have some built-in tools for the actual generation and processing of audio data, but…

As a side project for a hockey manager game, I created a small audio tracker, "HM Tracker," which was used to make the game's music. It is a browser-based tracker-style music workstation. All sound is procedurally generated from oscillators - no samples, no plugins. The UI lets you edit patterns on a step grid, pick instruments and chords, then export as a standalone JS music engine or WAV file. Built with vanilla JS and the Web Audio API (best experienced on a desktop browser). Made in the '90s demoscene spirit (at least the looks, anyway). Would love any feedback!

Hello HN, I had some christmas free time over the last two weeks (Merry Christmas btw ;-)) and used that time to completely recreate the website of my app[1]. I used all the fancy new tools. I didn't know some of them when I started. What was my goal? * Pretty website * Blazing fast * Mobile first * SSR * Webp support * Generally all the best website practices (high lighthouse score) What did I use? * Tailwindcss (https://tailwindcss.com/) * Tailwind Components (https://tailwindui.com/) * React (https://reactjs.org/) * ViteJs…

I know mentioning Michael Seibel is almost cheating, but this week he demonstrated the "leaky pipes" concept to me. Not that I know the guy, but in one of his videos he says something on the lines of "If you are unsure if you app is ready to be launched, just launch it. It's like a house with leaky pipes, just open the main, grab your tools, and start fixing wherever water is leaking". So we did it, we launched drummy earlier this week on /r/InternetIsBeautiful and we got very close to 10k users in just one day! Survived the hug of death, learned a ton, and made changes all around.…

It took me about a week to vibe code this 3D game engine with Opus 4.6 that I intend to use as a replacement for Three.js and React Three Fiber in my browser MMORPG, Mana Blade. I was not expecting to be able to reach that point so easily, but pretty much every feature took somewhere between 30 minutes and 1 hour - 1 to 3 prompts on average. It is vibe-coded in the sense that I haven't looked at the code, but I am very careful with my prompts and constantly have Claude reviewing the codebase, looking for performance and code quality improvements. It can reach 2000 draw calls on recent…

Hello, I'm Ricardo and this is an application I've been working on for the past half year. I've been making music for a while and I have a few hundreds of projects, which several of them, have names that are completely meaningless to me. So I sought out to create a way of always having an audio file from every project without the need for me to render anything manually. Well.. I kinda lost track of my goal and ended up creating an application to work along with the M4L device. That's how REKALL came about. It's a companion app for organizing/managing your Ableton Live projects. Import…
