**Question : My friend sent me this message via audio, but I dropped my salad on my computer before I could listen to it. Help!!!**
>First i had think , There is Audio Steganography. By doing the below things, I had got the message from Audio.
*Step - 1* :
- Download the Source File and [Sonic-Visualiser](https://www.sonicvisualiser.org/)
- Install sonic-visualiser
*Step - 2* :
- Open the AudioFile in Sonic-visualiser

*Step - 3* :
- Then add steg layer , which is persent in the layeropion

- Now got some meaning less number
- The number is : 49 52 51 48 54 7b 31 33 6f ...
*Step - 4* :
- I guess this is Hexadecimal Number.Use [Cipher chef](https://gchq.github.io/CyberChef/)

- So i can try to change Hexadecimal Number to Characters.
- Happy to see Message [Flag : IRQHT{xxxxxxxxxxxxxxx}] But Not correct
- Then Apply ceaser cipher to decrypt [ROT12](https://rot13.com/)

- Final Flag : [UDCTF{13s....}]
