AudioCraft – AI stem splitter and vocal remover with a browser-based mixer I’ve been building AudioCraft as a focused AI music tool for separating songs into useful stems. The main workflow is simple: * upload MP3, WAV, FLAC, or M4A * separate the track into vocals, drums, bass, and other instruments * preview the stems * mute, solo, and adjust individual tracks * create an instrumental version * download individual stems or all stems together AI Stem Splitter https://audiocraft.app/ A

Created a solar system renderer using Three.js and some vibe coding. You can listen to the sounds every planet makes when a probe/satellite passes beside it. Enjoy it here -

我把摄像头变成了乐器：从手势识别到 Web Audio，分享 5 个真正踩过的坑 最近做了一个有点不一样的浏览器小项目：用摄像头识别双手动作，再把手的位置和姿势映射成和弦、音高、音量和音色。 不需要安装软件，也不需要麦克风。打开网页、允许摄像头后，就可以隔空演奏。 项目地址：[GestureSynth.me]( https://gesturesynth.me/) 建议使用最新版 Chrome 或 Edge 。摄像头画面只在本地处理，不会上传。 ## 真正难的不是“识别到手” 最开始我以为，只要 MediaPipe 能返回手部关键点，剩下的事情就是把坐标转换成音符。 实际做下来发现：**识别出一只手很容易，让它变成一个“能演奏”的控制器才难。** 摄像头每一帧都会返回一组手部关键点，但这些坐标会轻微抖动，偶尔还会丢失。如果直接把原始坐标连接到音高或者音量，听起来会非常不稳定。 最后形成的处理链路大致是： ```text 摄像头 → 手部关键点识别 → 提取手掌位置、距离和手势 → 平滑、死区和状态保持 → 映
