Complete coverage of the science of acoustics and the art of acoustic techniques including room resonances, reflection analysis, comb filters, and the design of audio/video rooms for almost any purpose on acoustical concepts and terminology.
If you ever find yourself having to write a training manual on acoustics, this book should be your wing man. It was worth every penny I will now have to pay in library late fees.
This was the first one I read (related to music), It was a good introduction for learning more stuff like mixing, producing and (a little bit) of mastering.
Also it's pretty great for know what sound is, the way your ears function and other interesting things.
