Here is Beez, a web real-time audio experiment using smartphones as synthesizer effect controllers. This is our second Web Audio API experiment made in one Hackday at Zenexity. This time, we were much more focused on having the best latency performance: we used the bleeding-edge WebRTC technology, which allows you to link clients in Peer-to-Peer instead of a classical Client-Server architecture.

A few years ago, I wrote a little ActionScript 3 library called MicRecorder, which allowed you to record the microphone input and export it to a .WAV file. Very simple, but pretty handy. The other day I thought it would be cool to port it to JavaScript. I realized quickly that it is not as easy. In Flash, the SampleDataEvent directly provides the byte stream  PCM samples) from the microphone. With getUserMedia, the Web Audio APIs are required to extract the samples. Note that getUserMedia and Web Audio are not broadly supported yet, but it is coming. Firefox has also landed Web Audio recently, which is great news.

Peaks.js encompasses a suite of software tools designed to allow users to view and interact with audio waveform material in the browser. Peaks.js uses the HTML5 canvas element to display waveform data at different zoom levels, and synchronise the display to playback of an associated audio element. The component provides some basic convenience methods for interacting with waveforms and regions of time in the audio, e.g., for distinguishing music from speech, or identifying different music tracks.

ThreeAudio helps you create music visualizations in Three.js, by exposing audio data in GLSL shaders. It can be used directly with Three.js or as a tQuery plug-in.

Welcome the my HTML 5 Audio Editor. You can edit WAVE, OGG and MP3 files and export them as WAVE. This application uses no extra plugins like Flash or Silverlight, its written in JavaScript and HTML
