I realize not many people are using their iPod for reading audiobooks, but the touted features of bookmarking and “speed reading” with audiobooks on the iPod definitely sounded worth at least trying them out.
I hopped on over to the local library and grabbed a few books-on-CD, then iTuned them over. Well, the newly downloaded books did not show up under the audiobooks category. To cure this (at least on Windows), I had to rename all of the audiobook files from the “.m4a” extension to “.m4b”, delete the old files from the iPod, then upload the newly renamed files. Sucks that it takes doing that to get it to work, but it does work nonetheless. Now I can bookmark my place in any of the audiobook files, then go listen to music and come back to the place where I left off in the book. C’mon, that’s friggin’ cool.
The speedy reader is really nice, too. It doesn’t increase the pitch of the narrator at all, just speeds it up somehow without being overly fast. Someone’s probably timed the differences in Normal vs. Fast. (UPDATE: It seems it’s 25% faster, so for the math deficient that means you can read an hour’s worth of book in 45 minutes.)
UPDATE: Found more information on this here, but I didn’t notice an issue with needing to use a space at the end or caps.
UPDATE 2: Another thing I wanted to be sure to mention here. I’ve noticed several times already that if you have a rather large audibook file (larger than 1 CD worth, that is), you may run into problems with the bookmark feature when leaving the book and playing music. At least with two audiobooks so far, which I had combined into one huge file totaling maybe 10-16 hours, I would pause the book to listen to music. When I came back to the audiobook, my bookmark was there and I was able to continue playing from that point, but about ten seconds or so into the book, it would stop and dump me to the main iPod menu. When I went back to the audiobook, my bookmark was gone and I had to start over. Once I did start over and fast-forward to my old spot (which I luckily caught a glimpse of before starting), it would continue fine. This only happened when I left the book to listen to music; if I simply paused or turned the iPod off while listening to the audiobook, I could go back without a problem. Again, this only seems to occur with very large files.
UPDATE 3: Here’s a handy shell command I use on my .m4a files to convert many to .m4b files:
ls *m4a | cut -d . -f1 | awk '{print "mv ""$0".m4a" ./""$0".m4b""}' | bash
Works like a champ.
