New to Audirvana... Need license?

I’m new to this program and I am looking to test so that I can buy when the Windows version is released. Do I need to purchase a full license to test?

I wanted to participate in the beta, but I don’t know if the trial is time limited for this version.

There is a 15 days trial version available for any new user to be able to have the time to try before buying.
For the beta, I’ve renewed the trial for all the testers who have downloaded their first beta more than 2 weeks ago.
