[Dtb-talk] Converting tone indexed books to DAISY

[Greg Kearney]

When I first started this I tried recording the fast forward speed. It  
was too fast and resulted in poor quality recording I think 4X would  
be as fast as I would ever care to go.

The problem with detecting the index tone is that it is placed over  
the top of the recording. So it does not stand alone in the recording  
as a tone but rather is mixed in with the normal narration. It is easy  
to see on the display but would be hard to detect with a program as  
each tone would be mixed in with different narration.
