Plucked HTML5 Audio Editor, and ThreeAudio.js Visualizer - Badass JavaScript: "Plucked is the beginnings of a basic HTML5 audio editor based on the Web Audio API, which means that at the moment, it only works in Chrome, WebKit nightly builds, and Safari 6 beta. Although it says it can edit WAVE, OGG and MP3 files, I only had luck with WAVE files.
Currently, it displays a basic waveform like you might expect from an audio editor, and a spectrum visualization animates as you play. You can select, cut and paste, and even zoom in on the waveform. As for editing features, it currently supports gain adjustment, volume normalization, silencing, and fades. When you’re done editing, it will export your creation as a WAVE file.
Besides the Web Audio API, and canvas, the app is built on Twitter’s Bootstrap toolkit, and makes use of Web Workers and the File API. Of course, you can check the code for Plucked out on Github and check out the demo here.
