 Because SARAH is using coefficient adjustments and the inverse FFT to //simulate// filtering, I decided to call this //Harmonic Shaping// rather than "filtering". I'm not at all convinced this is a sensible alternative to conventional (time-domain) digital filtering, but it is certainly interesting, and allowed me to implement simple time-varying timbres (using both an envelope generator and an LFO) with just a few simple changes to the existing anti-aliased oscillator code. Because SARAH is using coefficient adjustments and the inverse FFT to //simulate// filtering, I decided to call this //Harmonic Shaping// rather than "filtering".

 +===== The details =====
 +See [[sarah_oscillator_details|this page]] for the gritty details of SARAH's oscillator implementation.

 +===== Skinning =====
 +As of 29 September, 2017, SARAH uses a single-view GUI instead of the multi-tabbed approach inherited from [[https://github.com/getdunne/VanillaJuce|VanillaJuce]]. See [[sarah_skinning|this page]] for some thoughts on the two approaches.
