![]() Personal StatementĪudio Transformer, the Web Audio Editor, is online in a functional demo mode. I am continuing to develop this project and would be thrilled to present it at the ITP show. I also added a Canvas to visualize the frequency spectrum, inspired by ICM and Marius Watz’ Sound as Data workshop. The frontend is built off of Wavesurfer, a JavaScript library that visualizes the waveform in a JavaScript Canvas. Shawn Van Every introduced me to SoX in CommLab Web, and helped me set it up on my server so that I can call it with PHP. Much of the Web Audio Editor’s functionality comes from SoX, a command line utility that has been around for over 2 decades. But HTML5, the WebAudio API, and Canvas open up a lot of potential for audio playback and visualizations. Web audio is still in its early stages, so the pieces necessary to build this weren’t available until very recently. I also drew inspiration from Pixlr, the online photo editor that I choose over Photoshop for quick little edits. I wanted to do this in the browser, rather than as a standalone application, after researching music education software’s transition to the web through my Technology for Music Education course (at Steinhardt). I wanted an easy way to make good sounds, and learn about sound in the process.Even though it was designed for an audience who has never worked with digital sound before, the Web Audio Editor can be of use to anyone who wants effects or just a quick edit. They find the default audio editor (Audacity) really frustrating, and I’m with them! So I decided to build an audio editor that does all the stuff that kids like to do (like reverse sounds, change the speed, and add reverb). I teach music workshops at an afterschool program where kids build their own sample libraries from scratch. ![]()
