FAUST: Slightly more advanced sawtooth gen with ADSR

Hey All,

Today I figured out how to use the FAUST libraries ("import" statements). In the source code for faust, there's a folder called "architecture", and there are files called "music.lib", "oscillators.lib", "effects.lib" etc...

These files can be included, and then you can use the functionality included in them! The following code shows how to create a sawtooth oscillator, and then apply and ADSR to the signal. Pretty simple, but very educational :)

Code:

// import the needed libraries
import("music.lib");
import("oscillator.lib");

// generate a sawtooth wave, using "saw1" from "oscillator.lib"
sawGen = saw1( vslider("Freq", 60, 0, 127, 0.1) );

// get variables for A D S and R stages, using sliders
attack     = 1.0/(SR*nentry("[1:]attack [unit:ms][style:knob]", 20, 1, 1000, 1)/1000);
decay      = nentry("[2:]decay[style:knob]", 2, 1, 100, 0.1)/100000;
sustain    = nentry("[3:]sustain [unit:pc][style:knob]", 10, 1, 100, 0.1)/100;
release    = nentry("[4:]release[style:knob]", 10, 1, 100, 0.1)/100000;

// set the process function, using the button to trigger the ADSR, and then volume scale the sawtooth
process =  button("play"): hgroup("", adsr(attack, decay, sustain, release) : *(sawGen));

GUI using JACK & GTK:

The comments there should tell you what it does, and the compilation is the same as the last tutorial... Enjoy the sawtooth madness!
