The 'ring' in this effect derives from the layout of diode nodes in the original analogue equipment, and also refers to the sound being increasingly modulated as it travels through the ring of diodes.

### Getting an analyser node for a sound object
You can obtain an analyser node for a particular Pizzicato Sound object by using the function ```getAnalyser```:
<a name="using-graph">
### Using Pizzicato objects in a web audio graph
You can use effects and sounds as part of an existing web audio graph.
<a name="using-graph-sound">
#### Connecting nodes to a Pizzicato.Sound object
Using the ```connect``` method, you can connect audio nodes to a Pizzicato.Sound object. For example:
```javascript
var analyser = Pizzicato.context.createAnaliser();
var sound = new Pizzicato.Sound();
var analyser = sound.getAnalyser();
sound.connect(analyser);
```

#### Creating a detached Pizzicato.Sound object
All Pizzicato.Sound objects are connected to the context's destination by default. In the example above, the ```sound``` object will be connected to an analyser node and it will also remain connected to the context's destination node.
To have a Pizzicato.Sound object that is not connected to the context's destination, use the ```detached``` option as follows:
```javascript
var analyser = Pizzicato.context.createAnaliser();
var sound = new Pizzicato.Sound({
source: wave,
options: {
detached: true
}
});
sound.connect(analyser);
```
<a name="using-graph-effect">
#### Connecting nodes to effects
Pizzicato effects can also be used in a web audio graph without the need to create Pizzicato.Sound objects by using the ```connect``` method.
Additionally, the ```connect``` method in an AudioNode can receive a Pizzicato effect as a parameter.
```javascript
var oscillator = Pizzicato.context.createOscillator();
var distortion = new Pizzicato.Effects.Distortion();
var analyser = Pizzicato.context.createAnalyser();
oscillator.connect(distortion);
