Esquissons
(by Theo Marchal)
Esquissons is a Grasshopper plugin which help you to design with sound. 
It sketches sound based on the sources and the geometries you declare !

V.3.0.1_minor update to simplify the installation and fix some bugs on the windows version
Esquissons is still in beta! As a tool "in permanent development" it continues to evolve according to the new possibilities offered by rhino, but also according to your feedback and suggestions. 

With Esquissons you will be able to declare sources, import sound files, and hear it inside the geometry you designed. 

The software interaction between sound and parametric space modeling is embodied in a 3D sketch modeled in Grasshopper and an acoustic sketch in a stand-alone application developed on MAXMSP, interactively connected to each other. Thus, the program is developed as an auralization tool rather than a calculation tool. It is indeed a question of being able to sketch a sound scene from the very first stages of design and thus inform the model.

V.3 UPDATE 
> Comes with an installer  > Crossplatform (Mac/windows) > Improved optimisation > Lot of new stuff/function > New icons ;)

Functions/component :
Listener : Place/Move the listening point in the scene, choose its orientation and size
Geometry : Determine the phonic opacity of a geometry but also its absorption coefficient
Sources : Position the source in the model, determine its size and choose the sound file it will play
Option for sources : Mute a source, manually adjust its volume and choose the degree of shuffle!
Built-in Sound : New simpler interface in the form of a list to access the built-in sounds. (more built-in sounds)
Main Engine : Optimized component (faster), you can lock the sources, enable or disable reverb, and choose between an indoor or outdoor sketch. The component returns, in addition to the sound, a visualization in the form of rays as well as the reverberation time per source and the amount of reverberation (mix) per source. 
Visualize Rays : You can choose how many rays are visible, at what distance from the source and the number of bounces you want to see !

Source code will be available on a github page : https://github.com/TheoArchi/EsquisSons

Feel free to ask anything by contacting me directly or via the github : remarks, questions, suggestions... I consider the developpement of this tool as an interative process : https://github.com/TheoArchi/EsquisSons/issues

If you encounter any issue with the installer, you still can install the software manually. Instructions here : https://github.com/TheoArchi/EsquisSons/blob/master/ManualInstall/Installation_Instructions.md
