"A series of eight lectures ... given at the Lowell institute in January and February, 1914, under the general title of 'Sound analysis.' These lectures have been rewritten for presentation in book form."
via Gersten
"this is a full downloadable book with diagrams, photos of sound waves using archaic photographic techniques (which someone will now use on their next album cover), and lots of sine/cosine math stuff about sound and theory laying the groundwork for sampling and synthesis. these guys were photographing and measuring the properties of real instruments...the only thing they needed was the technology to then reproduce what they measured...which we now have. dope and very scientific. we have it so easy."
