Can SC generate a frequency spectrogram of a given wav file? (and back again)

  2. Is there (an easy) way in Supercollider to convert it back again? Despite the effect it won’t be equal to the original sound file.

Assuming that you want to see it on NRT, this is the only thing that I’ve seen so far to do this:

(Anyway, it is already impressive!) Or am I missing something?

There is also a real-time spectrogram Quark:

Thank you very much! This is better for me for general purposes!
