Objective

Introduction to core.async and clojurescript by building an audio vizualizer.

Description

I am going through give an interactive walkthrough of the source code and demo the app. The app uses HTML5 APIs like File, WebGL and Audio. Also I will discuss my learnings about core.async. Communicating Sequential Processes (CSP) is a formal language for describing patterns of interaction in concurrent systems. core.async is an implementation of this paradigm in clojure.

Requirements

Some idea of Functional programming and Clojure would be useful.
