The Challenge


The Solution

We are getting a wav file to explore. By listing to it we only hear weird sounds in different frequencies

First what we always do with a file exploration


String tool:

Strings flag.wav -> no results

After a google search I came along a very good site that is explaining very well how wav challenges work ->

For the solution on this challenge

Download the Sonic Visualizer

Load the Wav file

Click on Pane -> add spectrum -> all channel mixed

See if the flag is correct

I must say I really enjoyed this challenge
