Thanks a lot for this comprehensive history lesson.

Back when I was introduced to FT in some Physics lecture I was happy
that I was able to use it and completely forgot to check the history :)
Probably related to why I favored experimental Physics over Theory.

>> The DFT (Discrete FT) is the same thing operating on sampled

correct.

Furthermore there are different kind of windows (here a window refers to
a block of audio-samples) and windows can overlap. That's where it gets
complicated.

The most commonly known window shapes are Rectangular window, Gaussian ,
Hann- and Hamming windows (the last two are cosine shapes) which allow
to avoid discontinuities when processing blocks.
