Hooohooh, that explains a lot about the style Ive seen some 'enlightened young socialists' toting about.


He's a rather charming looking chap tho.

More weirdness to pass the time/break your brain from one of the foremost internet archeologists. It's a lot of Internet, though, so use your judgement.

Although I think the human skeleton turned out to have been a wooden replica, which is more interesting, but less horrifying and less common.

I thank you for this contribution to my encyclopedic knowledge of weird and disturbing Internet things. Now please sign this restraining order, preferably while delivering another truckload of threads like this

Embedding 8-bit PCM audio into 24-bit color (8 bpp) .raw images seems to cause some strange issues once those .raw images get exported to .bmp with IrfanView, then reimported back into Audacity.

Spoiler: Explanation for both images (click to show/hide)

The top track is the original sine wave before exporting it to .raw.
The middle track is from importing the .raw file.
The bottom track is from importing the .bmp file exported with IrfanView.

Spoiler: As waveform (click to show/hide)

The top 2 tracks are 440 Hz sine waves. No issues here.
The bottom track, though, has some rather noticeable deformation. It's jagged. Also, the waveform gets cut off at points:

Spoiler: As spectrogram (click to show/hide)

The top track is basically a pure sine wave.
The middle track, while slightly noisy, is still a sine wave. I believe the noise is quantization noise from being crushed from 32-bit float down to 8-bit PCM.
The bottom track, though, while still a sine wave, has periodic pops in it throughout.

And I'm just using a sine wave to demonstrate, since it's really difficult to demonstrate the other strange effects it has on actual music in image form. It's like an effect, where, like, the song keeps trying to play over itself, as if there's 2 'play heads' ~100 ms apart.

I wonder if its fundamental cause is the reverse of when I tried low-pass filtering an image; instead of Audacity treating an image as an audio signal, it's IrfanView treating an audio signal as if it were an image. Then again, isn't .bmp is an uncompressed format, and as such, any exports to .bmp should be byte-for-byte identical to the source material, just reversed when imported into Audacity? It's worth mentioning that exporting from .raw to .jpeg back to .raw doesn't butcher the material this badly; it just ends up being more noisy. So is it a problem with the .bmp encoder?

Edit: Using GIMP to export the .raw file to .bmp produces the same effects.

Looks like some kind of quantization or aliasing effect.

Also, BMP format contains a header. Keep that in mind.

[methylatedspirit]

Why does it quantize it so 'strangely', for lack of another word, though?

I place the audio data really far away from the header (1 minute, give or take). Plus, compared to the size of the PCM audio data I'm embedding into the file, the header's miniscule. It's, like 50-something bytes of header, compared to 7 minutes of 44.1 KHz, 8-bit PCM. Actually, the blank space that I embed the audio into is just a blank, white, 5000x5000 .bmp image. Not that that matters, given that IrfanView detects that the resulting file is .bmp, yet fails to open it, so I just open it as .raw. I would guess that it writes a second header once I export it to .bmp?

Are you one of Google's corporate customers, or just some person?

Just some person, unless having a Youtube account counts as being their corporate customer.

[Il Palazzo]

Just some person, unless having a Youtube account counts as being their corporate customer.

I think that makes you their corporate product.

Yep. Products go on shelves, and don't get to have an opinion. If you want Google to care about your opinion, be a multi-billionaire.

But more seriously, Google has repeatedly shown that if it won't cost them money, they have no intention of regulating what's on Youtube, or how it is tagged. You might use somewhere else if you want children's content.

So, do creators tag them or does the algorithm tag them?
