Le Sound is a brand of procedural audio plugins created by Novelab. They exist for all of the main DAWs and are starting to be available for Fmod and Wwise.
As a sound designer I did some Pure Data patches prototyping which where then used to create some of these plugins with a tool used to convert patches into VST/AAX plugins. Most notably the plugin AudioSpace is completly based on patch.
I also helped with the QA for most of the plugins and helped to test the recent integration in Wwise (so far AudioWind, AudioRain and AudioMotors)
