Dr. Toole's 4th Edition Book is Coming! (Discount)

[jayapple]

Buy the translated one, and then contact Dr. Toole for the English pdf. It is not proper to just ask for the English version from another owner.

Thank you. I'll just wait for the fourth edition. It's unlikely that a dubbed version will be made for this one. I'm planning to buy the electronic version.

Years ago, perhaps 30, I wrote to the National Research Center in Canada to purchase a copy of the booklet/papers of this--quite big actually, Iike 75 pages, but not quite what we would call a book yet, at least not in the binding it had. Dr. Toole sent me a copy for no charge. I will forever be grateful for that. Thank you very much, Dr. Toole.

I purchased a Kindle version of the 3rd edition, but the layout was so bad as to be unusable. Diagrams and pictures many pages away from the associated text. I returned the Kindle version and bought the paperback.
Could I ask those of you that have an e-book version, which format (PDF? EPUB?) you have and whether you experienced similar layout issues?
My preference is to purchase e-books, but I’m a bit wary about this one

I purchased a Kindle version of the 3rd edition, but the layout was so bad as to be unusable.

I absolutely devour e-textbooks via tablet. I find the larger screen and color are crucial. Tablets are also just the right size for pdfs of the source papers (darn two column format).

Doesn’t have to be an ipad, kindle fire would work too. If all else fails there is always the Kindle pc/mac app. That would all for reading and taking notes at the same time.

This is great news and will buy for sure to add to my 1st and 3rd editions. Will be interesting to see if there is anything new on how to include dynamic capabilities (dynamic range, efficiency, distortion and compression by SPL by Freq etc) in the preference score methodology as opposed to the spinorama FR data alone.

Having limitless and effortless dynamic range in a speaker is magical to behold, even if the FR is not perfectly flat and/or the dispersion is wide and even (witness the love of JTR speakers in the HT crowd), but it's not clear if there is a rational approach to balance these characteristics relative to each other.

Amir and Erin do a great job sharing the Distortion and compression measurements so huge kudos and thanks guys, but would love to see if these could somehow be quantified into the preference score.

Subjective evaluations of audible distortion and compression in larger well-designed loudspeakers usually requires playing them at loud levels over an extended period of time (20 -30 minutes). With that, there are risks associated with damaging the listeners' hearing that most researchers are not willing to take. There are ways of mitigating this:
1) use a very large room and increase the listening distance or 2) make a binaural recording them at loud SPL levels and play the recordings back over headphones at reduced levels.

For these reasons, most companies rely on objective measurements to determine the max SPL limits of the loudspeaker where the measured distortion is above audible threshold and likely longer acceptable. If you have a Klippel analyzer you can measure the nonlinearities in the speaker, model/simulate and auralize them over headphones in a very controlled way.

Pre-order from Amazon is available now. The cover is black.

 

[Sigberg Audio]

Kindle edition not available in Europe(?) or at least not in Norway.

 

[erniebert]

Lucky that you had the book with you at the time.

But what did he sound like? Any good?

I'm sorry but I expected the answer to go like this:

Beautifully balanced across the audible audio spectrum, with deep, undistorted lows, scrumptious mids, and organic, unfettered highs.

The paperback version of this book is available from the publisher (Routledge) for pre-order after 10/7/25 for $59.99. This is $15 less than the current Amazon price for either the paperback or the Kindle version in the US.

I use a cheap Android 11" tablet and have pretty much stopped using my Kindle. The tablet experience is far better except for the weight of the tablet.

That makes sense, but is there more information on Distortion in the fourth edition? In the third I feel like it is talked about but not in depth. So I would appreciate some more knowledge about hearing limits of different kinds of distortion.

Other than that I really like the book and will buy the fourth edition! I would not have the capacity to get all the referenced papers, read them and and create similar knowledge for my self! Thank you!

Ho hum. Routledge have an unhelpful message that they can’t ship to Australia. And Amazon US won’t either. So it is $146 = 95USD purchased from Amazon Australia. At least I get Prime shipping. Grumble. Just ordered it. But a trifle miffed at the escalation in price down here. I don’t remember the 3rd edition being so bad. Maybe it is just the Oz dollar suffering in the current chaos.

 

[Jeromeof]

Pre-ordered my copy - Eur60 in Amazon Ireland which is a pretty good price.

 

[greyscale]

Will ship OCT. 28 in USA.

 

[MarkS]

Amazon in the US has the publisher's discount price for the paperback pre-order.

 

[nathan]

Nice but why give Bezos a cut? The publisher has already starting shipping orders. My tracking info says it will arrive this week.

 

[jeffbook]

Well, Nathan is right about the publisher shipping. My copy arrived on Saturday, October 11.

Now time to start readinn.....

 

[nathan]

In addition to offering the same discount as (and earlier than) Amazon, the publisher also offers free shipping (at least to my location) so it's not a bad deal at all, imo.

In the near future, to join ASR it should be mandatory to

a. buy Dr. Toole's book
b. take a simple pop quiz to prove you read the book.
c. Then you can post

The existing members can be grandfathered in or prove they have read previous editions.

Good lord! A sure way to stop all future audio research!

Good lord! A sure way to stop all future audio research!

Not that I actually endorse that proposal, but how in the world does familiarizing oneself with the existing research somehow stop all future research? What a weird mindset.
