You'd need DMTF Recorder if you have no experience with DMTF or (sorry) being partially or totally deaf.

Search about DTMF

You do have to find the right DTMF decoder tool, and then manually spellchack the resulting flag. Fun, but easy

What if the user is deaf? I would not be able to solve this without some help as I am deaf

Can you get the correct file so we can correct this?

Guys read about dial tone and DTMF decoding, search online tools or use git hub tools to extract numbers from the the .wav file. Listen how numbers are being typed, its important. Then try to decode numbers. Thanks to that challenge I've learned about DTMF and how to it works. I've also learned how to write python script for decoding these numbers.

First I felt like it was impossible. But I solved it

That was really cool and interesting, I've never done anything like that before

WOW dtmf New Cipher CTF. Every one want to take this CTF. Good Job bro :{)
