PDF2Tape 1.0 for Mac was available to download from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The program relates to Audio & Video Tools. We recommend checking the downloaded files with any free antivirus. The actual developer of this Mac application is Niles Mitchell.
From the developer:
PDF2Tape is an application that lets you record PDF documents into audio files using the Mac's built in speech technology. Play them back on your Mac, or sync them to your iPhone, iPod, or iPad for on-the-go listening! The possibilities are endless!
While AAC is preferred because of it's significantly smaller file size, some 3rd party voices may not support it. For that reason, AIFF is included as well.
