You can buy the full version of SplineEQ with a full commercial license for $29 (about €24, £21 depending on the exchange rates) by clicking the button below. You will be taken to the PayPal site where you'll be able to pay using a credit card or your PayPal account.
The full commercial license entitles you to free updates, the right to use and sell the resulting audio without limitations and gives access to e-mail support.
Mac users: Please make sure that everything works for you by trying out the free version. Any future problem that will arise on macOS will most likely not be fixed. Please consider switching to Windows (the license works for both).
Windows users: Everything works perfectly and will continue to do so for decades to come, enjoy!
