Many chapters still to go for me, but so far it is an informative, equasion-free examination of the determinators of realistic listening. You can get to the text of the book at Mr. Glasgal's site:
Ambiophonics,
2nd Edition
Replacing Stereophonics to Achieve
Concert-Hall Realism
By Ralph Glasgal
Chapter 3
Understanding Stereophonic Sound Fields
Human hearing using two ears is called
binaural and was developed by evolution. Binaural sound is what most of us listen to all
the time. Audiophiles sometimes think of binaural sound as a recording made with a dummy
head and played back through earphones. This is a poor imitation of the real thing and is
not what we will mean when we refer to the binaural hearing mechanism in this book.
