Audio knowledge general 2

  Mr. Iijima's writing. Book that wrote how to choose and basic knowledge etc. of speaker. It is a book for a super-disciple and a terribly comprehensible book.   

The price is confirmed with amazon.
Speaker introductory knowledge [jou](1979)

  Book in this system published ahead of Canadian copper Mr. "Comprehensible audio knowledge". I think that "Basic knowledge of comprehensible audio" or here is politely more excellent substantially of the book though there is somewhat old only in the book published 30 years ago. (Though it might be somewhat difficult because there is an expression in the content. )
