databending and raw import settings |

Hi all,
I have been trying to find image software for Ubuntu that can replicate a databending process I figured out on my mac. I used GraphicConverter 11 to import a .wav file as raw data, transferred the resulting image to GIMP and modified it, exported that as .bmp, and then used Audacity to import the .bmp's raw data, coming full circle back to audio.
I got my best results when I imported the data as a Grayscale image in Unsigned Long format.
With those specifications, aspects of the original file were recognizable in the altered version, and it was not totally destroyed. As a matter of fact, the end audio only differed significantly from the original if I actively edited it in image form (the IWarp effect is great for this). This process yields a very clean transfer.
I now have a new laptop with Lubuntu 18.04.5, for which GraphicConverter is not supported. I tried importing raw data with GIMP, but the import settings do not seem to include Grayscale or Unsigned Long. I've tried a few other image-editing applications, including Converseen, UFRaw, and RawTherapee, but I haven't found anything that will do what I need. Is there any way I can get GIMP to do this, and if not, is there another program for Ubuntu that may work instead?

Best algorithm for resizing images? |

I have some images saved, in the past I reduced the size of the images a lot to save disk space (for example, I reduced an image from 3840x2160 to 1280x720, that is, 200% reduction).
Now I need to go back to the original size, and well, that's a problem, because I kept these images for other people, and these people want the original image (they cannot suspect that the image quality has been reduced).
I know it is impossible to increase with the original quality, but what is the best algorithm to increase the size of images in Gimp to get as close to the original? To me, NoHalo looks the best, the others seem to blur the image.
There are some sites that promise to increase quality using AI for free, but what is the guarantee of privacy? I don't want private images stored or posted around. And it is very suspicious of a website doing this for free.

Not that easy to code, but the results are worth it:
Is it me or in the second image there is an illusion that the image has two levels, one in front with orange, red, and dark blue and one in the back with pale blue, green and yellow?

Selection -- Layer -- Manipulation |

This seems so simple, and it should be.
It's not.
Once again, I have created an (irregular) selection in Gimp. [[It is not a square, or circle, or rectangle, or anything 'easy' to work with.]] I cut it out with the free-select scissors. I have the 'marching ants' to confirm that I completed the selection.
Once more, I have copied the selection (both Ctrl+C, and from the Edit menu). Once more, I have attempted to paste the selection into a new layer. Once more I have created the Floating Selection. Once more, I have attempted to anchor the Floating Selection into a new layer.
It simply does not work.
I've seen and read maybe a dozen tutorials on this. I have followed to the letter the steps illustrated or described in the tutorials, over and over.
I always wind up with one of two results:
(1) An 'empty' selection in the new layer -- the 'marching ants' outline is there, but the content inside them is not. Or,
(2) A visible selection which cannot be operated upon, or moved, or manipulated in any way.
Is it possible for someone, anyone to provide ONE (or two) method, which will (1) successfully paste the selection onto a new layer, and (2) allow me to work on that selection in the new layer? Something that will work at least 80% of the time?
If I sound frustrated, it is because I am. I apologize if that comes through.
I'm merely seeking something that works, and something that is (mainly) reliable.
I thank everyone in advance for their answers, and for their patience with me. It is appreciated.
