ASCII encoded to hexadecimal

Generated using a custom Python script (audio stuffer) using pydub libraries.
Single tones generated using Audacity.



Reverse engineering tips:

First tones: 23212f
Last tones: 690a7d (ignoring separators)
Single tone length: 0,015 s
A bunch of zeroes (can be heard as a low pitched constant square wave in the video)
signifies a file separator. The file separator contains 332 zeroes.
Bash shell (or compatible) is required to run (the) decoded script(s).
