For this challenge, we are given a wav file.

Listening to the audio, there doesn't seem to be anything unusual. Opening the file in Audacity and checking the spectrogram doesn't reveal the flag. We decide to run strings again just in case.

(Note: The file is very large and may not load on the browser. To view it, download the file and open it on your device.)

The flag is the very last output.
