rotates an audio file by 90 degrees in the spectrum while being a reversible process with minimal loss (only floating point errors which are like -150 dB but thats literally silence ahaha~)

	import numpy as np
	import soundfile as sf
	from scipy.fftpack import fft, ifft

	def rotateSignal(signal,flip):
	if flip:
	signal = signal[::-1]

	x = np.concatenate((signal, signal[1:][::-1])) # concatenating the array with a reverse of itself makes it such that the fourier transform doesn't layer over a reversed version of itself in the inverse fft
	rotSig = ifft(x)
