Demonstration mode 1 

The module switches the noise cancellation 
on for 1.5 seconds, then off for 1.5 seconds. 
It will then move to the next level and repeat 
the process. This mode is particularly 
effective at demonstrating the different DSP 
levels. A lternatively pass a clean audio 
signal through the module to see hear how 
little the DSP alters the speech. 

Demonstration  mode 2 

The module switches the noise cancellation 
on for 3 seconds then off for 3 seconds. This 
is a good demonstration of the before and 
after effects of the noise cancellation. 

Note: 

To exit the demonstration
