Here you can buy licenses for VoceVista Video and Overtone Analyzer.

Our products come in several editions. Please note that the Overtone Analyzer edition does not contain Frequency Filters. Some tutorial videos still show filters in Overtone Analyzer, but the editions have been renamed in May 2017 due to the merging of Overtone Analyzer and VoceVista. For Frequency Filters, please get VoceVista Video or VoceVista Video Pro. You can compare the different editions on our Products page.

We recommend that you download and install the software before buying it to ensure that it runs well on your system, and that you selected the feature set you want.

Updates and License Renewals

Registered users get free updates for 12 months from the date of purchase. This is for all new versions of the purchased edition of the software that are released during that time.

After 12 months, you can continue to use the software indefinitely, but you won’t be able to install new updates. To upgrade to the latest version (and to get another 12 months of upgrades), you can buy a license renewal for 25% of the current price of a new license. If you have not upgraded for four years or longer, the price of the license renewal is 50% of the current price of a new license.

To upgrade, download and install the latest version of the software and activate it with your activation key. If you need a license renewal, the software will prompt you to buy one.
You can also buy a license renewal by entering your email and activation code here:
