Yes and no, depending on the product.

You need an account on this website to purchase and activate products under “PRODUCTS”  (Shop) for which we – DiBiQuadro Audio – are the owners of the technology.

In order to get our N4 Libraries instead it is required to register on Acustica Audio  website. Nebula is a product of Acusticaudio S.r.l.. Please follow the links under “N4 LIBS” to do so.


Products can be added to your shopping cart from “PRODUCTS” or the product page (except for “N4 LIBS” for which the checkout is not managed on this site). To finalise the purchase, click on the cart symbol and press “Proceed to checkout” button. Trial and Free products are free of charge, but they have to be activated like any other product.
Commercial products can be paid with the following payment channels:
* Paypal
You can pay with your credit card if you don’t have a PayPal account. We do not store any credit card data, payments are managed by the payment processors reported above. More details in our Privacy Policy.


In order to use your License Code / Coupon, you have to “buy” the related full product (ie: SaturnLO) on this website. At the moment of the checkout, you will be able to insert the License Code (no payment will be required to complete the purchase) or the Coupon (a discount will be applied, a payment for the remaining amount will be needed).


DiBiQuadro Center is the only way to install/authorize your products. It requires an internet connection on the system on which you want to install the product(s). Once a product is correctly installed/authorized, it does not require any internet connection anymore – it can work offline.


Free products have price 0€, no functional limitation and no expiration date.
Trial products have price 0€ and no functional limitation but they expire after 15 days from the generation of the related license.
Commercial (Full) products have price > 0€, no functional limitation and no expiration date.


There is a reason. All Free, Trial and Commercial (Full) products respect the following versioning convention.

Given a product version number x.y.z.w:

wit is increased only in case of cosmetic updates and/or bug fixes – ie: SaturnLO
zit is increased only in case of important updates and/or bug fixes – ie: SaturnLO
yit is increased only when the new version requires the generation of new user licenses – No need to purchase the product again – ie: SaturnLO – This will also give the possibility to regenerate the license on a TRIAL product already evaluated.
xit is increased only when the product has been completely restyled. – ie: SaturnLO – No need to purchase the product again, or to pay a “delta” for the update (to be confirmed).
