Audio Player with "Binaural Beats" tuned to the same key as your music

Hi HN, Gabriel here. This is a standalone binaural beat generator, combined with a two-deck local audio player built with the Web Audio API. It includes ten harmonic carrier pairs, seven brainwave-state presets, per-harmonic mixing (so the binaural tones aren't out-of-tune with the music), adjustable beat and carrier frequencies, two oscillator shapes, offline key/BPM analysis, automatic carrier matching, adaptive impulse noise, playlist support, and output recording. The main problem I've had with existing "binaural beat" generators is that the tone generated does not remain in-tune…

In plain words

This is a web-based audio player that generates binaural beats tuned to match the key and tempo of the music being played. Built with the Web Audio API, it features a two-deck mixer, seven brainwave-state presets, adjustable frequencies, and per-harmonic mixing to keep binaural tones harmonically aligned with the music. It includes playlist support, offline key and BPM analysis, automatic carrier matching, and output recording. The tool is designed for music listeners who want to combine binaural beat therapy with their own audio library without the tones sounding out of tune.

A local-first browser studio for building long-form headphone sessions from binaural tones, music, adaptive textures, and spoken-word audio. Binaural Studio combines a ten-voice binaural synthesizer with a local music deck, an independent spoken-word deck for audiobooks and other long-form audio, and a real-time master recorder. It can analyse your music in the browser, tune the generated layer to each track, move between state presets during a set, and record the complete result as one audio file. There is no backend, account, build step, or audio upload. Use stereo headphones and start at a comfortable volume. The state presets are creative sound-design tools, not medical treatments.

    Hi HN! I made Beatsync, an open-source browser-based audio player that syncs audio with millisecond-level accuracy across many devices. Try it live right now: https://www.beatsync.gg/ The idea is that with no additional hardware, you can turn any group of devices into a full surround sound system. MacBook speakers are particularly good. Inspired by Network Time Protocol (NTP), I do clock synchronization over websockets and use the Web Audio API to keep audio latency under a few ms. You can also drag devices around a virtual grid to simulate spatial audio — it changes the…

    If you already know what bytebeat is, you don't need an explanation. 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

    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…

    I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

    Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

  • A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

    Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
