I was listening to this book today in the workshop and noticed that Chapter 16 was repeated. On further investigation it seems that the whole audio file for Chapter 16 is repeated. If you go to about 13:40 in that file the second intro can be heard. The reader does a very nice job with the book, and I think the doubling must have been a typo in the cataloging process, or something like that. I think it might be fairly simple to remove the second half of that chapter's file, but I don't know how hard it is to change that kind of thing after cataloging.
I'll have a look at this - I am expecting I will need to do some listening to work out the cause. I don't think it's either of those. According to the thread a couple of files were swapped so I'll need to check them both
I'm sorry, I don't know what format it is. I got it by clicking the green Download button on the catalog page, and then put it on my little mp3 player that I can plug into earmuffs and wear in the workshop.
No worries. I confirmed it on the 128kb file, and the duration given in the project thread / MW was the doubled amount. So yeah, it just wasn't caught!
