FEND

FEND is a series posted to the second YouTube account between May 26 and June 4, 2016. There are 20 videos in the series (numbered 0 to 19).

Details

Through videos all have an identical length of 27:46, for a total of about 50,000 frames per video.

The composites made from the videos are generally color gradients.

2D composite

This composite by Tomas F is a long image with several colored bars:

It is worth noting that one section near the beginning of the combined gradient composite had an “island” like object in it:

3D composite

This 3D composite by Tomas F is several planes crossing through each other with some mountain-like shapes, http://tomasf.se/projects/semi/stl.html?path=FEND_composite3D.stl.

Audio

The audio in the FEND videos (at least so far) can be divided into three sub-groups. The sub-groups can be distinguished by their identical audio content.

Subgroup A is identified by a ~2s. scratching-type noise. Members of subgroup A: 0, 1, 3, 6, 8, 13, 15.

Subgroup B is identified by a ~1:27 “heartbeat” sound with a large DC offset (~ -.749). Members of subgroup B: 2, 4, 10, 11, 16, 17.

Subgroup C is identified by a ~20:18 throb/rumble sound with a large DC offset (~-.7275). Members of subgroup C: 5, 7, 9, 12, 14.

Method of testing for audio similarity

For each of the groups, /u/Unfavorablist opened two separate FEND sound tracks in Audacity. /u/Unfavorablist then inverted one and did a mix. Identical but inverted tracks should cancel each other out perfectly, as these did.

Reversing audio

On 2026-02 user Ben’s Fractals reports:

FEND 1’s audio seems to be reversing back and forth.

See how it mirrors horizontally.

In case you think this is some spectral error you can even see the wave-forms flipping.

One thing this reminds me of is Recycle which was a drum slicing program from the 90s. As a cheap method to do tail-extension for drums the audio would reverse back-and-forth as a ping-pong loop at the end of a segment and create these mirrored patterns.

Flip noise

In 2026-02 N25 CT13 writes:

I did find this exact wave form and other similar “flip” in FEND 1’s audio. It’s at the end part of the quiet scratching at the beginning.

You have to amplify the audio quite a bit to be able to see this.

I kind of feel that it could be noise and some kind of “audio encoding artifact”.

Sinc impulse

ben’s fractals: these waveforms on FEND subgroup B and C are sinc impulses, https://en.wikipedia.org/wiki/Sinc_function

This probably means that the audio was resampled from a really low sample rate back to 44100hz

Relation to Fond

ben’s fractals: Fond and Fend are related audio wise

In the right channel of FOND 5 you can see it transition from FEND subgroup B to FEND subgroup C

N25_CT13: the repeating beginning section has 25/26 big peaks (first one possibly cut off at the start) and 10 small peaks

it could be letters and numbers in order (A to Z; 0 to9) being put there as peaks to refer to as an alphabet when reading the more random section of peaks
