Double-speed playback for iTunes?

"Here is what Apple suggests (see ""Get caught speeding""):


Open the selected song file with Quicktime.
Choose “Show A/V Controls.”
Move the “Playback Speed” slider at the bottom of the window to your preferred speed.


In Snow Leopard's Quicktime Player, option-click on the fast-forward button to increase speed in 10% increments."

"Not quite the answer you asked for, but quite closely related and I hit this site when I was still looking for the following, so I thought a post here might do someone else a favor.

After spending a while trying to get my mp3 lectures to play at double speed on my iPhone, I finally figured out the thing that iTunes uses to tell whether the file is a podcast or audiobook is a setting in:

""File-> Get Info-> Options tab-> Media Kind""

Set that to podcast or audiobook and voila, your iPhone will give you the option of 2x speed.
This is great, because you can select a bunch of tracks and change the whole lot with a few clicks."

"If you also want to speed up video playback on your iPhone or iPad you could try Swift Player. It lets you change speeds even directly from any website, including YouTube.

If you want to change speed on the computer then the easiest way is with VLC.

As in one of the comments, when in iTunes I selected "Get Info" on all tracks for a book, went to the "Options" tab, and changed "Media Kind" to "Audiobook", I got the 2x speedup option. No need to convert to ACC etc file (mp3 worked fine).
