## Challenge Overview

> In this challenge we have to deal with a .wav file. When we open it, we can clearly hear the morse code pattern. Translating it we get: "Can you see me?". This is a clearly clue to set a spectrogram view in an audio program like Audacity. Then, we get the flag.

However, in this type of challenges my workflow is to first see the spectrogram or if it's something strange about the file, not actually decode the entire morse code because it can be a little time consuming.<br>

In this case the best option to view it almost perfectly was Linear scale.</p></figcaption></figure>
