As part of the ANR WASABI french research project, by collaborating with researchers and developers from other groups or companies, we recently introduced a WebAudio plugin standard (aka VSTs in a browser). In this demo, we propose to showcase some of the large set of WebAudio plugins we’ve already been developing. These are running in different host environments such as Amped Studio, an online digital audio workstation or directly in a virtual pedal board application more suited for live performances. The plugins are of different kinds: audio effects, virtual instruments (synthesizers), guitar amp simulations. These plugins can be connected together via audio or midi routes, and written using multiple approaches/programming languages such as JavaScript, DSL languages like FAUST or C/C++. Our plugin standard is unique today, quite well suited to the Web platforms (eletzach plugin has a URI and can be downloaded and run on the fly by host applications), and relies on recent W3C standards such as WebComponents, WebAudio and WebMidi.
