add further fft manipulations

capital-G commented 2 years ago

adds the content of spect_resynth that is currently in #58 and reworked it a bit and mentioned in #57

I think it is best to add the notebooks one by one with a PR on its own.

Sadly this notebook is really big b/c of all the soud material included (which is stored as a wav blob) which is less than sub-optimal but the only other solution is to generate wav (or flac) files and store them as files in the repo - I don't know if this is really better (although this allows for the site to load faster b/c then the DOM is not full of binary blobs of the audio files in between).

To reduce the size a bit we should at least squash the commit (although it seem that right now it is only 1 commit diff to main so there would be no need for a squash?)

Otherwhise how would we properly reconstruct the audio of e.g. 440 Hz sine wave when not knowing at which angle/phase the sine wave is at each point.

Müsste man sprachlich umformulieren – aber man kann das weglassen, denke ich.

To get rid of the phase we can use

Da wäre es gut, kurz zu erklären, wie Frequenz und Phase in der komplexen Zahl repräsentiert ist?
