I had my first stab at generating some sound today. It was a total flop: Not only does it not sound like the real thing, it doesn’t in fact sound like anything that is not random noise. (But I was pleasantly surprised to find that once I had all the data in .npy format, access becomes instantaneous so long as I specify 'r' in numpy.load(). Converting all those .vtu files to .npy was not in vain.) I need to figure out a way to make something that sounds less random. The question is how.
