## Writeup
When I played the audio file, I immediately recognized it. I had already completed a challenge featuring the same kind of audio file, and after a long, tedious search, I discovered that this type of file is an SSTV (Slow-Scan Television) signal. SSTV is a method for image transmission over radio signals, which can be decoded using dedicated software such as **MMSSTV**. Let's play this audio file in **Audacity** and output the signal to a virtual audio cable connected to **MMSSTV**. If everything is set up correctly, it should generate this glorious image:

There's some text suspiciously similar to the flag format `QHPGS{UHZOYR_Z3Z3_1BEQ}`. A simple ROT13, and we get our flag `DUCTF{HUMBLE_M3M3_1ORD}`.
