python,audio,centroid,spectral

I have never implemented this before but as far as I understand the Wikipedia formula, it should be something like this: import numpy as np def spectral_centroid(x, samplerate=44100): magnitudes = np.abs(np.fft.rfft(x)) # magnitudes of positive frequencies length = len(x) freqs = np.abs(np.fft.fftfreq(length, 1.0/samplerate)[:length//2+1]) # positive frequencies return np.sum(magnitudes*freqs) / np.sum(magnitudes)...

Most hardware and drivers assume that you're working with a gamma of 2.2 (or sRGB, which is very similar). So if you try to display a raw file with linear RGB info (i.e., a gamma of 1.0) the display image will be too bright. 3D graphics hardware is designed for...
