WxMCTF Forensics 2 - Sneaky Spying

Shhh, don't tell the MGCI kids, but I spied on one of their conversations! Uhh, I couldn't really understand what they were saying though. Can you let me you what they said? -For educational purposes of course.

Oh, they also had this open on their phones. I don't know what to make of it though: https://pages.mtu.edu/~suits/notefreqs.html

Enter any letter characters inside the flag as upper case (e.g: wxmctf{H3LLO})

About the Challenge

We have been given a wav file (You can download the file here)and we need to find the music notes

How to Solve?

To get the flag you can use Sonic Visualizer and add a new pane called Peak Frequency Spectogram

Hover your mouse over the yellow light to get an alphabet such as (ABCDEFG) and repeat for each note
