Enable pause-resume bookmarks on AAC-encoded files Apps
According to a knowledge base article you can enable any AAC format music file for bookmarking (continues playback from where you last left off), by changing the type code of the AAC file to "M4B ", including the space at the end, but not the quotes. You'll need to use a program such as FileInfo to make the change. If you want to revert back to an unbookmarked AAC file, change the file type back to "M4A " for regular AAC files or "M4P " for tracks purchased from the iTunes music store.

[robg adds: If you try the above link to the Apple KnowledgeBase, you'll find that it fails. For some reason, shortly after publishing the article, Apple pulled it. You can also change the file type if you've installed the Developer Tools by using the SetFile utility in the Terminal. Once changed, you should be able to play and stop and pick up again at the same spot when you return.

Warning: Not knowing why Apple removed the KnowledgeBase article, consider this hint somewhat experimental -- perhaps there are downsides to this change that we are not aware of.]

An AppleScript 'Make Bookmarkable' has been posted for this purpose:

Enable pause-resume bookmarks on AAC-encoded files

Here's my pet theory/conspiracy on why the article no longer exists. "Bookmarkable" content was a major selling point of iTMS and Audible.com purchases! (Especially lengthy audiobooks, or hour long radio shows.) Previously, if I'd ripped it myself or captured the stream manually, it wasn't as good as a "real" iTMS or Audible.com purchase. Posting this article allowed folks to bridge that gap.

Maybe one arm of Apple didn't talk to the other arm? Maybe Audible.com complained?

Enable pause-resume bookmarks on AAC-encoded files

I posted this question on MacFixIt and didn't get a response. I performed the above hint but it didn't completely solve my problem.

Lets say I have a playlist with 30 songs on it. I start playing on song 1. At some point I sync the iPod (say it is in the middle of song 17). After detaching the iPod there doesn't appear to be a "go back to current bookmark" feature. If I manually go to song 17 it will resume playing at the mid way point because the bookmark has been saved.

Is there any way of making the iPod go back to the current bookmark so that I don't have try and remember the last song I was playing?

My books are broken up into multiple files as well. I always just create a smart playlist that looks something list like this:

Match [all]
[artist] [contains] "enter artist/author name"
[album] [contains] "enter album/book name"
[play count] [is less than] 1

Whenever you finish listening to a track it will be automatically removed from the playlist. I use this all the time from my iPod and Desktop.

Simply changing the file's extension to "FileName.m4b" appears to have the same effect.

That doesn't work
Authored by: Cantus on Mar 12, '04 03:04:21AM

No, this does not work by itself.

But, if you have an utility to set Type & Creator from Extension, it eases the process.

Does this mean you could take a purchased music file, change its code to "M4A " and *remove* the authorization restrictions associated with iTMS purchased music (ie: sharing, burning, etc.)?

If so, I could see why Apple would pull the knowledge base article... they'd be going against the very authorization scheme they made!

No. Changing the file type has nothing to do with DRM.

Also, thanks for mentioning my script and my site.

Anyone know how to set section/chapter marks in an m4b file?

Audible.com's files have sections marked, enabling one to press the "next" button to jump to the next section.

I've done this on quite a few m4a files and it's worked fine -- in both iTunes and on my iPod. However, bookmarks aren't active when playing the file within the Finder.

Perhaps you're doing it differently than I am. I changed the name of the file before I imported it into iTunes (by copying to my library). Maybe iTunes changes the file type automatically.

My last reply was to Cantus' statement that changing the file's name to m4b does the same thing as changing the file's type.

To anyone who stumbles on this older hint, there is now a checkbox in iTunes track info dialog that enables this for any iTunes track
