Dale: For Book Wizard info, start the program and hig F1. Since Digital Talking Books (DTBs) don't have a standard bit rate for = there output files, there is no calculation you can use to determine how = much space/hour a book will take. Most commonly, however, DTBs use either = 48,000 BPS or 32,000 BPS. In the case of 48,000 BPS, one hour will require = about 20.625 MB. In the case of 32,000 BPS, one hour will take just under = 14 MB. Rob Meredith >>> drlieser@xxxxxxx 08/20/04 01:01PM >>> I've looked for information about Book Wizard, but haven't found it. What = is it for? Also, what is the approximate ratio of time vs. file size of Daisy text. That is, how much memory per minute, or some such conversion? Thank you. Dale
