The Siren kernel of the Loris interface is in the classes LirosSound and LirosAnalyzer. The class LorisAnalysisConfiguration represents the variables used by the analyzer.
Simple Loris tests
To load a sound file and run it, saving the result as SDIF and opening a display (read this method to see how to use the Loris API)

Loris Analyzer Configuration
There is a special class that manages the Loris analyzer settings; it has an editor default Loris analyzer settings (when set to resolution of 70 Hz) are:
hopT 0.0142857
winWidth 70
size 1291
BWwid 2000
sideLobes 90
cropT 0.0142857
freqDrift 35
freqFloor 70
ampFloor -90
Loris Sound
LorisSound is a subclass of sound that has before/after versions of a sound and methods for managing the various envelopes and analysis behaviors.
LorisEditor GUI
The LorisEditor GUI has 4 main panes: 2 for sound views, a function view, and a spectrum view. Depending on the application, these might be an original and a resynthesized sound (for tuning analysis parameters), or two different sounds (for morphing). The menu bar at the top of the editor view contains items for all the important Loris functions.
CSL Models in Siren
The CSL unit generator models are in the Siren.CSL namespace. the CSLGraph class represents an instrument or DSP patch in the same sense that a CSL instrument object does. There are numerous example methods in the CSLGraph class.
To oest a CSL graph; play a simple note
