What it does
Make beats in your browser with 16 velocity drum pads, a step sequencer, swing, sampling and WAV export. Free, no download, no signup.
A web page cannot listen to another browser tab - BAP only hears files you drop in and your microphone. A small extension bridges that: it records whatever a tab is playing and brings it here to chop onto the pads. A third-party tool, not part of BAP Studio - sample only what you have the right to use. You play by what you hear, and what you hear runs late: the audio pipeline delays every sound on its way to your ears, and your press takes its own time coming back in. BAP subtracts both from every hit it records, so unquantized takes land where you meant them - not a constant few dozen milliseconds behind the beat. The reported latency is the browser's word for it; the tap test measures the…from bap.studio

I made a generative online drum machine with ClojureScript2025 · dopeloop.ai · ▲202After two years of development, I'm super excited to release Beat Maker! This is my take on what I hope is the best free, web-based drum machine. My goal was to build something that was not only fun and easy to use for beginners but also powerful enough for serious producers. I did extensive research on existing drum machines, analyzed their UX, and tried to build something that adds something new. It's a nearly 100% client-side app, written in ClojureScript, and is a PWA so you can install it to your home screen for an app-like experience. Besides the standard grid editor, Beat Maker has…

Beats, a web-based drum machineJan 2026 · beats.lasagna.pizza · ▲160Hello all! I've been an avid fan of Pocket Operators by Teenage Engineering since I found out about them. I even own an EP-133 K.O. II today, which I love. A couple of months ago, Reddit user andiam03 shared a Google Sheet with some drum patterns [1]. I thought it was a very cool way to share and understand beats. During the weekend I coded a basic version of this app I am sharing today. I iterated over it in my free time, and yesterday I felt like I had a pretty good version to share with y'all. It's not meant to be a sequencer but rather a way to experiment with beats and basic sounds,…

Clipto MCP▲655Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
