Hello im pretty new to grasshopper but am learning it slowly for my design technology class. For my project i want to take a sound file(. wav), and connect it to grasshopper and rhino to visualize pitch and frequency of the given input sound file.It wold be connected to a polygon or point cloud as i want it to read as a shape in the end as a form of architecture or a environment. I was wondering what the best way to do this is?Ive found that people have done this through processing with ghowl and also with firefly?  
Could anyone tell me the easiest way(based on a beginner knowledge) to do this? Or if their is any tutorials or code that could help?  
Much appreciated,  
Andrew
