AudioBook Stitch

AudioBook Stitch combines some of the best features expected in a AudioBook Binder software - allowing you to combine and stitch your mp3 files or audio book chapters into one audiobook file.

PLUS it allows you to export your completed audiobook in a select speed (temp) without the chipmunk effect; resulting in audiobooks at speeds unto 4x
If you're sick of downloading or ripping audiobooks in separate audio chapters then AudioBook Stitch is the AudioBook Builder you want on your MAC OSX Dock.
AND if you purchase this app now, you'll get free upgrade access to some killer now features in development before we raise the price.
