/**
 * I'm trying to define a lot of Audio Micro Libs with Browserify (NPM style) and the require() mecanism
 * 
 * Our Audio Micro Libs will require an audio context to work 
 * (e.g. we will need to access the sampleRate field or use some createNode methods of the web audio context)
 * 
 * + Eventually we can use different audio context: the "main" one and/or an OfflineAudioContext 
 * which will be used to fastly compute some audio and returns audio buffer.
