RoomTuned
Fix your room acoustics from a single recording
What it does
RoomTuned analyzes your room acoustics from a short clap recording and turns it into a clear, actionable treatment plan. Upload a 5–7s recording from your phone and RoomTuned analyzes it and tells you what’s wrong and how to fix it with actionable treatment recommendations. No equipment, no technical knowledge. Results in about a minute. It’s designed for creators, podcasters, home studios, and anyone who wants to improve their room sound without wasting money on treatment based on guesswork.

Hey there! I made a little app that lets you to calibrate your turntable by putting on any record and tapping a button. It's called Grooved and it uses your phone's microphone to see how fast your platter is going, almost like magic. You can see what it looks like in action here: https://twitter.com/OKatBest/status/1795453042994680148 The app itself is free without ads, subscriptions, or trackers. It's a tool I built for myself, and I just thought someone else might want to use it too. I have never seen this technology being used before, all other apps require you to…
- EVEdit videos faster by automatically removing silences2022 · kapwing.com · ▲171
Our team is filled with technologists and creators, and when we record and edit videos, 80% of the time is spent chopping up the video, removing silences, and picking the right takes. So we decided to build a tool that did that for you — or at least get you there most of the way! Our initial implementation is somewhat naïve and uses a user configurable silence threshold that just reads in volume levels. In the future, we’d like to use a frequency-based approach that focuses on the human voice. We’re also open to ideas, so let us know if you have any!
- IMI made tool for slicing up samples to Ableton Move presets2024 · github.com · ▲50
I recently got Ableton Move and was disappointed by how difficult it was to convert samples into Move-compatible drum racks, so I made a simple CLI tool for that. I hope others find it useful, and at some point, Ableton sees the need and provides us with a built-in solution.
- FSfree studio quality noise reduction for music2023 · tape.it · ▲14
Dear HN, this is Thomas from Tape It. We're releasing our studio quality noise reduction software as a free web app today. You can try it at: https://tape.it/denoiser Listening examples: https://www.youtube.com/watch?v=gRjxY7GTV6Y We've been researching on this for over two years, and will present the paper next week at the Audio Engineering Society conference in NY. You can read about the research here: https://tape.it/research/denoiser Short version: we combined a classic DSP denoiser with a neural network that controls it. Training this it…
- CACabin Audio – EQ your headphones using your spatial perception of sound2025 · cabinaudio.com · ▲5
My friend Tyler and I built a website that you can use to make your headphones (or speakers) sound better. It helps you find EQ settings that change the soundstage of your headphones. Soundstage is the space that music appears to fill when you play it through a system. On most headphones, the music sounds like it’s coming from inside your head, which isn’t ideal. Our website helps you move the music from inside of your head to into the room. This makes instruments sound massive and can dramatically improve clarity, impact, and enjoyment. Don’t try too hard to imagine it - just know that if…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
