What the demo covers

The demo follows one learner's capstone from raw audio to a device that wakes on a keyword and stays under a power budget.

You will see the dataset split, the quantisation step and the accuracy trade-off it forces, the firmware ring buffer, and the current measurements before and after duty-cycling.

Pause points are marked where the course asks you to make the same decision yourself.
