 > The [WebAudioAPI](https://developer.mozilla.org/en-US/docs/Web/API/Web_Audio_API) provides a powerful and versatile system for controlling audio on the Web, allowing developers to choose audio sources, add effects to audio, create audio visualizations, apply spatial effects (such as panning) and much more.
 
 
+## Example

+You can find here [a functionnal exemple](https://github.com/dlepaux/realtime-bpm-analyzer-exemple) of this tool with `userMedia (microphone)` and `audioNode` usage.

 ## Usage / Requirements

 2. Connect the [AudioNode](https://developer.mozilla.org/en-US/docs/Web/API/AudioNode) to the [AudioContext](https://developer.mozilla.org/en-US/docs/Web/API/AudioContext) **and** create an [AudioContext.createScriptProcessor()](https://developer.mozilla.org/en-US/docs/Web/API/ScriptProcessorNode).
     ```javascript

 This library was been inspired from [Tornqvist project](https://github.com/tornqvist/bpm-detective) which also based on [Joe Sullivan's algorithm](http://joesul.li/van/beat-detection-using-web-audio/). Thank you to both of them
