# Information example

This example will show how to get several times of information using DPF.<br/>
The plugin will not do any audio processing.<br/>

In this example the Plugin will have a lot of parameter outputs which the UI uses to get info from.<br/>
This includes buffer-size and time position. Sample-rate can be access directly from the UI.<br/>
The UI will show this information as text.<br/>
