Under “What is Audacity?” at http://audacity.sourceforge.net/about.php
I found the following verbiage.
“Audacity version 1.0.0 is the most stable version we have released yet, and many people have found that its unique features and intuitive interface make it more enjoyable to use than other audio editors, including commercial ones.
The developers of Audacity have also released version 1.2.0-pre2, which is a beta-quality preview of new things we are actively working on. It contains many, many new features, but is not quite as polished and stable.”
Which version of Audacity are you using?
Will your wav files created by TextAloud play in a session of Windows Media Player?
