♐PORT is a video posted to the 3rd youtube channel account on December 31, 2017. It is 1:13:38 (however due to encoding errors it only shows up as 1:13:29) long and contains a series of moving images. The 3rd youtube channel was opened on December 10th, but undiscovered until decrypting the New Year’s Eve tweet on January 1, 2018.

There is an intermittent high-pitched tone throughout the audio track. Visual analysis of the spectrogram shows 28 such bursts:

Closer observation shows there are, in fact, four high-frequency “spikes” in the audio: the largest at 2815 Hz, and then at roughly 5600 Hz, 8490 Hz and 14200 Hz.

(An audio sample with those high frequencies removed can be heard here.)
Also of note is that it appears that all audio frequencies above 13000 Hz have been cut.
Underneath that high tone and throughout the track is a sputtering stereo track with almost musical features that may or may not be looped throughout the duration of the file. Near the end of the track, there is the normal audio but with a higher pitch.
