Indeed very fascinating. Reminds me of doing something similar, albeit a thousand times dumber in ~2004 when I had to find a way to "compress" interior automotive audio data, indicator sounds, things like that. At some point instead of using traditional copression, I synthesized a wave function and and only stored its parameters and the delta from the actual wave which achieved great compression ratios. It was expensive to compress but virtually free to decompress. And as a side effect my student mind was forever blown by the beauty of it.
