Alexander Wilson Studios has released AudioBookMaker for Mac OS X 10.2.
This utility uses the operating systems text-to-speech feature to produce audio (AIFF) files from any ordinary text file. Users can also reduce or increase the approximate-words-per-minute count from 50-500 wpm.
Once produced, the audio files can be drag-&-dropped into iTunes for conversion into MP3s for playback on iPods, for example. The solution employs any one of Mac OS X's 22 'voices'. It is a 656K download.
AudioBookMaker costs just $2.50. A note on the developer's Web site explains: "The ability to create these files is built in to the operating system. Alexander Wilson Studios simply developed the interface to make it as easy as drag-&-dropping or cut-&-pasting."
