The Web Audio API, currently available in Chrome, provides a considerable amount of aural power to developers interested in integrating audio into their apps and games. Low latency audio playback, audio generation and realtime effects are available with a sensible API in Chrome stable.

We worked with gskinner.com to develop Technitone, a web audio experience that lets you join other players to plot tones on a grid, construct melodies and modify the output with a robust toolset of effects.

  • Your tone samples can come from your own recordings, or any of the available samples.
  • The left side Tools panel offers realtime audio filters, like echo reverb and pitch shift.
  • We keep you connected to other players in realtime using WebSockets and Node.js.
  • You can drop into solo mode or invite your friends to join you in a session.
  • Get inspired by others’ audio creations in the gallery.
If you’re interested in the techniques and software behind the project, take a look at the case study with plenty of sample code and demos on HTML5 Rocks: http://www.html5rocks.com/en/tutorials/casestudies/technitone/
