After doing some processing on an audio or image array, it needs to be normalized within a range before it can be written back to a file. This can be done like so:
# Normalize audio channels to between -1.0 and +1.0 audio[:,0] = audio[:,0]/abs(audio[:,0]).max() audio[:,1] = audio[:,1]/abs(audio[:,1]).max() # Normalize image to between 0 and 255 image = image/(image.max()/255.0)
Is there a less verbose, convenience function way to do this?
matplotlib.colors.Normalize() doesn"t seem to be related.
