Trial Version (zip file)
This version will allow you to record, but when saving, it will save only 10 seconds of your recording. It is otherwise identical to the full licensed version.
A single-domain license costs $99. To purchase a license, fill out and return the software license agreement, then remit payment to my PayPal account (dhoopingarner@gmail.com).
The source code is also available under a separate license. Contact me for details.
