24 alternatives to Modembin – A pastebin that encodes your text into real FSK modem audio
A fun weekend project: https://www.modembin.com It's a pastebin, except text/files are encoded into .wav files using real FSK modem audio. Image sharing is supported via Slow-Scan Television (SSTV), a method of transmitting images as FM audio originally used by ham radio operators. Everything runs in the browser with zero audio libraries and the encoding is vanilla TypeScript sine wave math: phase-continuous FSK with proper 8-N-1 framing, fractional bit accumulation for non-integer sample rates, and a quadrature FM discriminator on the decode side (no FFT windowing or…

Hi HN, r2t2 is a command-line tool for transmitting data through sound using the PC speaker on the motherboard. The name of the tool is a reference to the R2-D2 robot from Star Wars :) In short, you type some message and it gets FSK modulated and transmitted via sound through the PC speaker. Note that this is the speaker/buzzer that you connect to the motherboard and not the regular speakers that you connect to the sound card. I also made a simple web page that listens to the sound emitted by r2t2 and decodes the received messages. The page can be used by simply opening it on your phone…

Hey HN, just wanted to share my success story with CompressX, my FFmpeg wrapper for macOS. For those who may not be familiar, FFmpeg is a powerful tool for converting, streaming, and recording audio and video content. I started CompressX as a weekend project to serve my 9-5 jobs, primarily to compress demo videos for uploading to GitLab and sharing with my colleagues. It took me 2 weeks to make the first working version. I shared the demo on Twitter and the reaction was extraordinary. People loved it, they said that I was bringing the Pied Piper to life. Four months later, I hit the $9,000…

Hi HN, I’ve been working on a browser-based tool for exploring and debugging Web Audio API graphs. Web Audio Studio lets you write real Web Audio API code, run it, and see the runtime graph it produces as an interactive visual representation. Instead of mentally tracking connect() calls, you can inspect the actual structure of the graph, follow signal flow, and tweak parameters while the audio is playing. It includes built-in visualizations for common node types — waveforms, filter responses, analyser time and frequency views, compressor transfer curves, waveshaper distortion, spatial…

I'm sure folks here have seen pastebins a thousand times. There's no innovation left in this space – and that's kind of the point. When I wanted to self-host a pastebin, every option I found was too much. Git-based version control, OAuth, elaborate admin panels. I just wanted something I could deploy in under a minute with a CLI that actually works. So I built pbnj (yes, like the sandwich). What it is: - A minimal, beautiful pastebin with syntax highlighting for 100+ languages - One-click deploy to Cloudflare (free tier gives you ~100,000 pastes) - CLI-first: pbnj file.py → get a URL, copied…

Hi HN! I’m excited to share AudioNimbus, a Rust library that brings the powerful spatial audio capabilities of Steam Audio to the Rust ecosystem. Whether you’re building games, VR/AR experiences, or simulations, AudioNimbus makes it easier to integrate realistic, immersive audio into your projects. Steam Audio is a toolkit for spatial audio, developed by Valve. It simulates realistic sound propagation, including effects like directionality, distance attenuation, reflections, and reverb. It’s used in games like Half-Life: Alyx and Counter-Strike 2. Rust is increasingly being adopted in…

I wanted to listen to music with friends who live far away. Not "watch a YouTube video together" - actually share what I'm hearing in real-time, like we're in the same room. Pulse is what came out of that. Anyone can host a live audio stream from their browser tab or system audio. Listeners join, music recognition identifies tracks automatically, and there's chat with 7TV emotes. No account required - you get an anonymous code and you're in. We're running demo rooms that stream NTS Radio and SomaFM 24/7 (indie project, not affiliated - we backlink to the original stations). There's also…

I vibe-coded a speech-to-text tool for Wayland that works for me. You trigger it with a keybind, speak into your mic, and it transcribes using OpenAI Whisper or Google STT (local is coming), then either types it directly into your active text field or saves it to the clipboard. It uses PipeWire for audio capture and works signal-driven, so there's no background process running. Just on-demand transcription when you need it. I've tested it on Niri and it should work on Hyprland, though I haven't tested GNOME or KDE yet. This was a one day Rust project and probably has some bugs since I just…

I thought it would be great to share code snippets without saving them on a server, so I created http://mem.pe It allows you to paste code and save it in your browser's local storage. When you share the URL of the pasted code, other people will connect to it via web sockets. For example, this http://mem.pe/#sge/5 you will be pulling from my browser. I'll keep it open for a while. If you close the web app, your code paste will not be available for anyone to see, until you open the web app again. This is obviously, not suitable for using at forums and other places…

I built a software-defined radio transmission platform that runs on a Raspberry Pi Zero W. It spawns its own WiFi hotspot and serves a web UI — connect from any device and you have a portable RF signal generator with 12 transmission modes: FM broadcasting with RDS, FT8, RTTY, FSK, POCSAG paging, Morse code, SSTV image transmission, voice cloning via live mic, spectrum painting, IQ replay, carrier wave, and frequency sweeps. Everything runs through a browser interface. Upload audio files, type messages, configure frequencies, and transmit. The Pi's GPIO pin does the actual RF generation via…

I originally added this to my site to speed up my video editing process. Last year I started a youtube channel and for some of my longer videos it's annoying to rely on youtube or capcut to transcribe when Whisper is open source. Capcut also recently updated their T&Cs to say they own your content if you use their app, so I cancelled my subscription. Another use-case I have is recording my claude prompts as audio, transcribing them, and then pasting them into my terminal. I mostly work on the CLI (claude, ffmpeg, whisper), but I wanted to make a browser version. Not reinventing the wheel…

Disclaimer: this is vibe-coded — ( what i see in the exported html 3. It helps me help our designer to produce an actual "resizable" figma, so that they finally understand the pain of "ok it works when you click play on the iphone 17 frame you put, but what about an iphone12 ?" (I was always able to say that, but before I wasn't able to point out what was wrong, now I can) How it works: When you open a Figma file in the browser, the editor loads the entire scenegraph via WebSocket as Kiwi-encoded binary frames. This tool captures those frames via Chrome DevTools Protocol, decodes the binary…
