Audio Stegano

This challenge gives us another audio file. This time the actual audio doesn’t sound like anything in particular. Sound like waves?

Let’s open it in Audacity and look at the spectogram.

It kinda looks like text ? Looks like some kind of writing.

Let’s zoom in that the frequency, looks to be just under 1000 hz.

Yeah, that is clearly text. It kinda looks like the second word is password ? Let’s try to clean it up a bit using the spectogram settings in audacity.

If we change de Window size from 256 to 2048 we get this.

We got what we were looking for.
