:index:`MP5`: DFT
########################

This MP is about using the DFT to create and filter images and audio
(textbook chapter 8).

* `mp5.zip <mp/mp5.zip>`_ contains the code.
    * Download the code and unzip it into some directory.
    * An example run-through is in `mp5_notebook.html <mp/mp5_notebook.html>`_.
    * Go to a terminal, and type `python grade.py` to test-grade your code.
    * When it works on your machine, then you can try uploading **only** the file ``submitted.py`` to the MP5 assignment on Gradescope.

Extra Credit
--------------

* `mp5_extra.zip <mp/mp5_extra.zip>`_ is the extra credit assignment.
  This adds one more file for you to work on (``extra.py``), and one more
  visible test file (``tests/test_extra.py``) with its accompanying
  solutions file (``extra_solutions.hdf5``).
* When you've finished revising ``extra.py``, you can test it on your
  machine by running ``python grade.py``.
* When it works on your machine, upload **only** the file ``extra.py``
  to the ``MP5 Extra`` assignment on Gradescope.
