A Ruby toolkit for Faust DSP: generate Faust code from Ruby, or convert Faust to Ruby.
gem install fraustoOr add to your Gemfile:
gem 'frausto'- ruby2faust - Ruby DSL that generates Faust DSP code
- faust2ruby - Convert Faust DSP code to Ruby DSL
require 'ruby2faust'
code = Ruby2Faust.generate do
freq = hslider("freq", init: 48, min: 20, max: 100, step: 1) >> midi2hz >> smoo
amp = hslider("amp", init: -12, min: -60, max: 0, step: 1) >> db2linear >> smoo
osc(freq) >> lp(2000) >> gain(amp)
end
