Apple’s iDevices are magical, but when it comes to audio, they do have a limit – they can’t play back tracks that contain more than about 2 billion audio samples. Sounds like a lot (nice pun!) but works out to about 13.5 hours of audio at 44.1 kHz (great quality), 27 hours at 22.05 kHz (good quality), all the way to 74 hours at 8kHz (“Collect phone call from the ocean floor, will you accept the charge?”). What to do when your latest audiobook purchase came unabridged, in a crate of two dozen (or more!) discs? There’s no magic bullet – but lucky for you, Audiobook Builder automatically splits your Projects into Part files that work with your iPhone, iPod or iPad…and you get four options – Part styles – that tell Audiobook Builder how to go about it. Here’s a little bit about each Part style:
Break Between Files
This is the default Part style when you first start using Audiobook Builder. When you select “Break Between Files” you also get a “Target Length” setting to tell Audiobook Builder how long you would like each Part to be. Audiobook Builder will add as many of the audio files in your Project as possible to each Part, up to the Target Length you select.
Break Between Chapters
This Part style is very similar to the Break Between Files Part style, but the breaks occur between the Chapters in your Project instead of between the original audio files. You still get to select a Target Length so Audiobook Builder knows how long you would like each Part to be. Audiobook Builder will add as many of the Chapters in your Project as possible to each Part, up to the Target Length you select.
Like it sounds, the Equal Length Part style doesn’t break between files or Chapters. Just pick a Target Length and Audiobook Builder will split your Project into Parts that are exactly that length. One caveat: Parts may begin and end in the middle of spoken words.
Audiobook Builder will create a Part for every Chapter in your Project.
That’s Audiobook Builder’s Part styles in a nutshell. Go to the Finish section of your Project and press the Build Options button to find ’em. If you’d like any additional details drop us a line at firstname.lastname@example.org!
