🎵 Audio & Music (37)

@yungbeto: I’ve been making a lot of audio experiments for my own amusement. They all have some potential to drain your cpu, sorry! https://www.noisetable.xyz/ - a collection of chance-based audio ‘channels’ in a VCR inspired interface https://concrete95.net/ - a musique concrète web app that’s made to look li | link, link, link
@Balgair: It’s dumb, but…. I made a scraper that searches through all the news and finds anything ‘war’ related. It then summarizes it and give me that new in the Star Wars crawl with music.
@ingvay7: I shred guitar in the evenings to focus on technique, but a hectic day job means I get almost no time to twiddle knobs on my amp sim chasing the right tone. So I built a tool where I just prompt “Brian May Solo Bohemian Rhapsody” — the LLM fills a small JSON contract and feeds to a script that gener | link
@jfim: A pile of various tools: A self hosted web archiving tool with support for extendible processing pipelines (eg. extract article -> translate -> summarize -> generate tags, download video -> split audio track -> transcribe -> summarize), which led me to make a managed chromium browser with extensions
@mybbor: Before agentic coding went mainstream, one of my main use cases was creating sticker designs for concerts and music festivals. Creating the stickers and giving them away was a good way to meet new people. I used OpenClaw to make a health and wellness coach agent that tracks calories and alcoholic dr | link, link, link
@josh_p: - A telegram bot that messages me in the morning and afternoon with a todo list essentially. It’s connected to Google Calendar and a crude memory database (SQLite). The kids wanted me to make it sound like the character Yarnaby from Silksong. - Automated backups of steam saves for when my kids wante
@gbro3n: A music theory learning tool. I’m building bits as I learn new areas - https://www.asmusictheory.com I also built a kanban board with agent integration and context management, with a vs code extension to go with it (also helps with git worktrees too): https://www.agentkanban.io There is AS Notes - a | link, link, link
@ilikeatari: I made myself a tool that connects to my cdj3000x and A9 mixer over network and gets all data live from them. So bpm, pitch, song metadata etc. The tool also connects to my recordbox library and runs custom ML algos to classify for pitch, stems, tonality Phrasing, energy etc. Long story short it bas
@kmike84: * plugin for Logic Pro to A/B mix with reference tracks, with ai-based stem splitter (e.g. isolate vocals in ref track, and compare with your vocal track) * plugin for Logic Pro to simulate how a mix will sound on my macbook and phone (I captured real impulse responses for that, sounds very close) *

@chadd: 1. i’m notoriously bad about filing expense reports for my own companies. i built a macos desktop app which integrates with Plaid and keeps track of the things i need to expense, using an LLM to guess which company and whether it’s reimbursible. 2. A MacOS app to manage my wife’s SD Cards - download | link
@geekster777: Made a fun app that generates daily riddles. If you give an llm an answer then ask it for a riddle, it’s pretty clever and fun to see what connections it draws: https://riddles.jpn.fyi/ I’m also currently working on an app that lets me hum a tune into my phone and generate guitar tabs. The audio pro | link
@sevennull: replaced some paid apps with local - google reader rss replacement and send web to kindle. most ambitious was browser extension to automate booking reservations since captcha and timing were critical. swamp/evaporative cooler controller that monitors rate of change of relative humidity and sends RF
@nicotejera: https://wodblock.com an app to track workouts, can generate functional/hiit workouts too using AI (give me something leg heavy but with some cardio, etc). https://jazzcatalog.com an app the learn jazz standards.

@jhiggins777: A vocabulary flash card app. I know I know, there’s a million. None of them had share extension feature so whenever you are reading on the web or in a book you highlight the word share directly to the app and it automatically looks up the definition. Also added a voice review (with gemini native aud | link
@mulhoon: I recently built a physics-driven auto-panner based on PONG, so I can also play PONG inside my DAW. https://portwaydsp.com I also built https://plugins.audio - a Dribbble-esque showcase of audio plugins. It’s been a dream to be able to work in the audio software space. I’ve been a musician, designer | link, link
@epiccoleman: All kinds of random stuff really, but to filter it down to only the noteworthy ones: Tuber[0] - this is my favorite, use it multiple times a week. It’s just a little CLI wrapper around yt-dlp for my most common use cases - downloading the video, or the audio, or the subs. And then, if you’ve got the | link, link, link
@j23n: I’ve been making a set of local- and files-first iOS apps for myself - Photo Gallery, Music and Contacts. I use Linux on my computer and an iPhone and wasn’t happy having to use a cloud to sync my data between my devices. Syncthing/Synctrain + my apps allow me to keep everything on my private networ | link
@critbit: Recently I made Vocast ( https://github.com/cnrmurphy/vocast ) - a cli driven tool that uses local TTS models to convert articles to “podcasts” and expose them via RSS feed. I wanted a way to listen to articles without having to pay for an app. I convert the article on my PC (which gets added to a m | link
@EastLondonCoder: Some things I’ve used AI for the last year or so: - small club website: https://www.kolibrinkpg.com - ticketing system with Stripe payments and QR scanning at the door - Instagram/media ingestion for the club site - genealogy tool with GEDCOM import - scripts for downloading/archiving public-domain | link
@czhu12: Built this little tool for editing audio with text https://edit-with-text.oncanine.run/ (Transcribes the audio, marks the timestamps, so you can delete a word in the transcript, and it’ll crop out that segment in the audio) | link
@moose333: Scrobble tui to track vinyl record listens on last.fm, sourced from collection on Discogs Calibre web UI 2.0 to replace Calibre’s mediocre web interface. Used for browsing ebook catalog, searching and cataloging with a simple list feature. Project Gutenberg local mirror UI to browse my local copy of
@manphone: I made a media center replacement for something like plex or jellyfin, streaming video or audio whenever I am; transcoding, subtitles, specialized dupe and renaming metadata. A little automated datawarehouse that manages all my output in an object store. My own tag system of course. A personalized e
@ben_w: German language tutor, a midi piano tutor, and an isochrone map generator. Static site generator for my blog, or at least bits of it.
@rootCompany: I built several prediction models for the market price of gold and cryptocurrencies. But this is always more a fun task than serious stuff - you can’t trade with it. Yes, I think it would be possible, but not w/o having the hardware and data resources. I also built a music player with an LLM agent,
@bijowo1676: I am working on my own Youtube Music/Spotify replacement, just so I can ditch the youtube premium on mobile. Already have $180 ARR prebooked (the money that I used to pay for youtube music), looking forward for more. if anyone has links for open-source self-hosted spotify/yt music replacement, I wou
@jeromechoo: Built an Apple Watch app that streams music from Plex. It’s more stable than Spotify and Apple Music and it’s been a blast running to my own music collection!
@hannofcart: Hi HN, I built (yet another) webapp (PWA) for looking up guitar scales and a bunch of other tools. https://guitar-tools.eejalab.xyz/ There are plenty of other tools already that do this but hopefully this one adds some quality of life niceties such as dark mode and a mobile responsive design that se | link

@mjbrownie: I’ve been reading Finnegans Wake and not making much sense of it so I wrote a data pipeline to scour the web for interpretation books / guides (which I also can’t be bothered actually reading) and coupled it with an prompt to image pipeline. It’s now a readable albeit silly picture book to go along
@ipunchghosts: I built a synthetic aperture sonar / radar simulation engine so I could generate endless amounts of procedural generated scenes to train a world model. Data for sonar is especially hard to come by. https://gergltd.com/aperturelab/ | link
@BoredPositron: I restore old non-functioning radios with nice design and good audio. I replace the old tech except the speakers with a raspberry add a mic array and package them with an easy to use ubuntu. whisper and the small gemma models made everything so much easier and private. I basically rewrite the whole
@NietTim: Thanks for the reminder, I made a very simple and small mac os guitar tuner and intonation app (all others are either paid, have in app purchases or are outdated) that I still need to publish!

📝 Writing & Text Processing (5)

@jboggan: I built a half-baked CRM that has a lot of custom fields and visuals for statistics that are relevant to my potential customers. I’m selling primarily to registered data brokers, so being able to pull up their self-published compliance stats (gleaned from their own privacy pages or public filings) a | link
@yaodub: Built a quant system that reads earnings transcripts for what management is trying not to say. The model is surprisingly bad at this. Turns out management is too.

@deevelton: a tool that helps me work in hallucination-sensitive contexts https://github.com/dvelton/eyeball | link
@robviren: Automatic self hosted transcription service. So nice to be able to get my thoughts all down as context for projects. Really accelrates things.

💻 Developer Tools & CLI (44)

@asciimoo: I’m working on a self-hosted search service called Hister ( https://hister.org/ - https://github.com/asciimoo/hister ) with the goal to reduce dependence on online search engines and AI answers. Hister is a full text indexer for websites and local files which automatically saves all the visited page | link, link
@aakresearch: - A little script that is best described as “symbolic submodule” workflow enabler for git: https://github.com/fontmaniac/symgit . As in “symbolic link” vs “hard link” - where hash tying host repo and pseudo-submodule is not git-generated, which makes “submodule” completely substitutable. For the des | link, link, link
@lormayna: My favourite football team was really at risk of relegation, then I created for me and my friends an MCMC bayesian simulator to estimate the relegation match by match. It was an opportunity to get used in real life to some concepts (MCMC, Metropolis-Hastings, etc) that I always struggled to understa
@margarita_dev: On my list of build it from scratch has always been to build a programming language. So with the help of AI I was able to get it done! Why did I build it? At work I’ve seen two major problems with our ai workflows/ skills libraries. There is a lack of determinism when your whole workflow is a markdo | link, link
@rrook: I’ve written my own programming language. IMO, “good architecture” exists outside of specific language choices - SOLID, various design patterns, etc.. I’ve always felt like I’m implementing the same high level design in any language I’ve worked with, it’s just manifested and looked different, depend | link
@egorelik: I’ve used AI for a number of Emacs-related utilities and configs. Just today I created a script to reproduce the particular combination of MSYS2 packages I use for my newer on Windows setup - the hard part being to get native comp working. Small, but it’s the sort of rarely used convenience I wouldn | link
@anotherevan: First personal little thing was a little mobile friendly website for taking coffee and tea orders. Two pages, one for someone to enter orders, second for listing orders and marking them as done. Was a bit of a gimmick idea I’d had in the back of my head for family lunches to save me running around w
@Lerc: After dropping the keyboard for the TV one too many times, the touchpad stopped working. I looked for a decent remote keyboard app to use on the tablet, and found nothing I liked. I ended up asking an AI to make something that served a webpage that connected back to itself via websockets. It provid
@ryanchants: I have a service that runs on my home server and uses the Ubiquiti API to detect when I’m on a zoom call. It then pauses my Sonos network-wide. Unpauses when the call is over. The next step of it is to have it’s own podcast library, so I can have my own little talk radio going on in the background a
@tmoertel: I made a quick web app that lets me easily perform Bayesian evidence updates for a set of competing hypotheses. You drop your hypotheses into rows. Then for each piece of evidence, you add a column and fill its values with the odds of observing the evidence given that the corresponding hypotheses ar
@delecti: I wrote myself a little CLI app for generating 2FA codes because I got tired of the hassle of opening my phone and typing them in. So now I can just do ‘toof nas’ and get a code for my Synology account in my system clipboard. It supports nicknames for accounts, in case I’m thinking of “nas”, “synolo | link
@fasouto: I’m building a source code analyzer with AI. It’s a TUI that you poin at a local codebase and it generates Mermaid diagrams. While I was doing it I needed to render those diagrams as ASCII and I was surprised there’s no Python library for Mermaid to ASCII. So I wrote one: https://github.com/fasouto/ | link, link
@sciyoshi: A docker-compose equivalent for running native processes: https://github.com/sciyoshi/decompose Similar to another tool called process-compose but with a CLI that mimics the docker one more closely and doesn’t start a TUI by default. Useful if your team’s on nix and doesn’t need containers. | link
@mbvisti: Mainly Andurel, which is the fullstack framework I always wanted for Go It follows a lot of the conventions of Rails which is probably why it has turned out quite well https://github.com/mbvlabs/andurel | link
@farseek1: I built a little web app that just collects job descriptions - currently up to 3m+ live / 15m dead descriptions - I mostly just use it to search to find stuff out - I should probably make they the main feature rather than the matching service idea. https://farseek.io/ | link
@hallucinate: Been working on this spaced repetition app / incremental reading app. I used SuperMemo for about a year straight, found the UI not that great, so I decided to make my own incremental reading app. Think: incremental everything. Supports multiple spaced repetition algorithms FSRS-6, SuperMemo 18, Supe | link, link
@marcinignac: A github client / dashboard that can pull 20 of so repos for all internal and client projects in one UI so I can stay on top of project delivery and long standing bugs.

@johncch: I built a color palette tweaker very specific to my OCD needs: https://archives.fifthrevision.com/color-generator/index.htm… I also have a local zsh autocomplete macro that let’s me type things like “git rename annotated branch” and ctrl-g and it will get me the actual command. There’s also a ctrl | link
@farbklang: It evolved out of some weird interaction someone was smartassing me that the moon wasn’t full when I was pointing to how pretty the full moon was. After that, between a friend and myself, it became a bit of a running gag how full (or not full) the moon actually was. This was my first real project I | link

@onlyrealcuzzo: I’m close to releasing a memory safe programming language, with a declarative concurrency model, that runs on a Go-like runtime. It has “levels” of compilation, with EASY mode being about as easy as Ruby, and the compiler can present you with options to get that as strict & performant as Rust/Tokio.

@fwn: I rely heavily on DeepL Write for my day job, but I dislike the constant logouts, nagging, and laggy UI. I coded a DeepL Write replacement that uses the same layout (two text windows side by side, with the left window for entry and the right window showing suggested edits as an actionable diff), but

🌐 Browser Extensions & Web Tools (12)

@neonglow: I built a browser extension that stops animated images such as GIFs by default. I’ve always found it annoying that browsers autoplay animated images, and there still isn’t a built-in way to control that behavior. The extension shows the first frame and adds a play/stop button directly on the image. | link, link, link
@academic_84572: I made MooBlock - a browser extension for digital self-regulation. Basically, it adds a small timeout before you can access a distracting site. This timeout grows the more you visit these sites, and decays when you stay away. And yes, there are lots of cows. The longer you stay on distracting sites, | link, link
@smusamashah: Lookup or modify selected text using AI (chrome extension). I just select any text and click the tiny popup button “what’s this” and get an answer right there on the page.

@aleqs: I’ve made a general repo linting tool [0][1]. Originally it’s purpose was to replace a bunch of repo hygiene/structure validation scripts I ended up adding as I noticed various sloppy AI changes.

@0john: Built an Android app to streamline the messaging web-apps I use to stay in touch with some contacts. I already refrained from installing those services’ apps due to privacy concerns. https://gitlab.com/not_john/palpipe | link
@jazzido: The small local ISP that I use doesn’t provide a Tizen OS app for their VOD service, so I built one mostly by pointing Codex at the .apk of their Android app. https://github.com/jazzido/bvcplay-tizen | link
@jasonhayer: I made an android app for my badminton club which allows me to take registered players from a whatsapp group through to Square for easy payments and reconciliation.
@itpragmatik: In 2023 I wrote from scratch a iOS native app using SwiftUI. This year I used AI extensively to improve and add many features to it in a span of couple months.

🎓 Learning & Education (16)

@linsomniac: I’ve redesigned my workstation OS using NixOS and Claude Code and it’s been a huge success.
