LOSSLESS Spectral Rotation : A better method!

Finally, a completely clean way to achieve a 90 degree rotation with no loss! this method is a perfectly clean way to do a 90 degree spectral rotation, spectral inversion and time-frequency swap without losing information Relevant video :    • 90 degree rotations : further spectral rot...   now my thought process was "haha what if i just took the FFT of an entire audio signal and saved that out" to realise that the FFT is a complex function, and that if i wanted real output i'd need to sacrifice information (lose the imaginary part of every coefficient) and thusly lose most phase information. fortunately i did a tad bit of screwing around and i have found a way to do it, i went down a few too many rabbit holes and got lost in some complicated notation but with enough rock-bashing i managed to concoct a little script to flawlessly spectrally rotate an audio file by 90 degrees also looked into this "hermitian symmetry" stuff but only to realise i was dealing with a real-valued signal all along (duh) aha~ you can find the script here : https://gist.github.com/Ravarcheon/3a... for requirements and stuff do pip install scipy numpy soundfile and if you're getting that one cffi backend error may all deities help you because i've never seen that in my life
