A FAUST-based re-creation of the power amp stage for WebAudio-based simulations of guitar tube amplifiers

International audienceIn this paper, we detail our on-going browser-based re-creation of a famous tube guitar amplifier and describe the JavaScript implementation we have been developing using the WebAudio API. The tricky part of such an amplifier is the power stage (Power Amp) which contains a parametric negative feedback loop. We show the limits of the high-level WebAudio API layer, and how FAUST allows us to re-implement the Power Amp more faithfully. Finally we also compare FAUST vs JavaScript development, and mention future optimizations
