I love the screenshots. How did you get the animation?
Thank you! I have spent some time getting good at making them, because I think they are a great way to share stuff here.
It's pretty simple, really:
- I use Rigol Bildschirmkopie to capture screenshots at "as fast as possible" or every 1 second[1]
- I import the screenshots as layers into a GIMP file, then Optimize for GIF, and save as GIF with "replace" turned on
[1] It's important to get the smooth fast images to use USB and not LAN. LAN can only capture about 1 picture every 3 seconds, whereas USB can capture 3 to 4 pictures a second.
[2][2] If you use the fastest capture rate, some display elements (like the measurements at the bottom) will be slow to update and thus will be incorrect in the screenshots. Even worse, some display elements (like the FFT itself!) will never actually get computed because the screenshot requests interrupt them. In these cases, I have to slow down the acquisition to once per second.
If you have any more questions, feel free to ask here or in PM.
