Hello everybody, I just returned from giving a lecture to the Toronto section of the AES, as noted above. It was great to meet some old friends and to introduce some new audio enthusiasts to the science of audio.
The 4th edition is more than a book. It has a website - not yet accessible, but should be soon. I have already complained to the publisher.
Books are always limited by page counts and old content must be omitted to include anything new, and this time I have two extra authors. We planned in advance to have a website and the first version of it contains some historical stuff that some greybeards may find interesting, some on LP playback systems that will no doubt upset a few fans of the format. There is an expanded discussion of ITU and EBU recommendations that are in bad need of updating.
Perhaps the most important website content are some slide shows that summarize some book content, including some new material. Educators may find them useful, but I think almost anyone should scan them for an overview of specific topics. The last slide show is about "translation" and it shows spinoramas on a wide selection of pro monitors and different kinds of consumer playback devices. There are some surprises, I think. The audio world has changed for the better - dramatically.
What is now need is for people to pay more attention to trustworthy measurements and less to "opinions" formed under biased circumstances. But human nature is powerful. I focus a bit on this in my Toronto lecture, which you might find interesting. I apologize for my voice giving out near the end - age is showing . . .
I have ideas for more, and we have a window of several weeks after which we can have some revisions and new material uploaded, so stay tuned.
Cheers,
