End User License Agreement
Last updated: September 14, 2026
This End User License Agreement ("EULA") is a legal agreement between you ("Licensee") and A2D Sound, a brand of AYA Labs ("Licensor"), for the use of any audio plugin software, presets, sample content, documentation, and updates (collectively, the "Software") provided by A2D Sound.
By installing, activating, or using the Software, you agree to be bound by this EULA. If you do not agree, do not install or use the Software.
1. License grant
Subject to your payment of the applicable fee and compliance with this EULA, A2D Sound grants you a non-exclusive, non-transferable, revocable, worldwide license to install and use the Software for your personal or commercial music production work.
2. Permitted use
The license is granted to a single user (you).
You may activate the Software on up to three (3) computers that you own or primarily control (for example, a studio desktop, a laptop, and a backup machine).
You may use the Software to create, mix, master, perform, and distribute audio works without paying additional royalties to A2D Sound. Audio output you produce with the Software is yours.
3. Restrictions
You may not:
Share, lend, rent, lease, sublicense, sell, or otherwise transfer your license, license key, installers, or account credentials.
Activate the Software on more than three computers concurrently.
Reverse engineer, decompile, disassemble, or attempt to derive the source code of the Software, except to the extent expressly permitted by applicable law.
Modify, adapt, translate, or create derivative works of the Software.
Remove or alter any copyright, trademark, or proprietary notices.
Distribute the Software's installers, presets, or sample content as standalone files, sample packs, or as part of any other product.
Use the Software to develop a competing product.
4. License transfer
Licenses are non-transferable. Resale of licenses is not permitted. A2D Sound is not obligated to honor licenses obtained from any third party.
5. Activations
Each license includes 3 activation slots. If you need to deactivate a machine (for example, before selling or replacing it), you can do so from the Members Area. If you exhaust your activations, contact support - we will reset them on a reasonable basis.
6. Free trial
The Software may offer a free trial of seven (7) days. The trial starts when you click "Start Free Trial" in the Software and requires an internet connection. One trial is granted per machine: it is recorded by A2D Sound's server against an identifier of that machine and cannot be restarted by reinstalling the Software, resetting the machine, or changing user accounts. During the trial the Software is fully functional. The trial checks in with our server while it runs; if the server cannot be reached, the Software continues to work for up to 48 hours from the last successful check. When the trial ends, the Software stops producing audio until a license key is activated. Trials are free of charge and are not eligible for refunds. We may change or withdraw the trial offer at any time; a trial that has already started runs to its end.
7. Data processed by the Software
To activate, validate, or deactivate a license, the Software sends your license key and an identifier derived from your computer (the "machine identifier") to Lemon Squeezy, our licensing and merchant-of-record provider. To start or check a free trial, the Software sends the machine identifier to A2D Sound's server at a2dsound.com. Once per day the Software requests a small version file from a2dsound.com to learn whether an update is available; that request carries no license data, although our server logs the requesting IP address as any web server does. The Software does not transmit your audio, your projects, or their names. Licensing and trial data are stored only to enforce this Agreement and the trial terms. Lemon Squeezy processes purchase and license data under its own privacy policy. For how A2D Sound handles personal data, see our Privacy Policy. The Software cannot be used without activating a license or starting a trial, so it cannot be used without contacting these servers.
8. Updates
A2D Sound may, at its discretion, provide updates, bug fixes, or new versions of the Software. Updates are governed by this EULA unless accompanied by a separate license. We do not guarantee that any specific feature or update will be made available.
9. Ownership
The Software is licensed, not sold. A2D Sound and its licensors retain all right, title, and interest in and to the Software, including all intellectual property rights.
10. Third-party content
Some Software components, presets, or audio content may include third-party material licensed to A2D Sound. Such material is provided under the same restrictions as the rest of the Software.
11. Third-party software
The Software includes software developed by third parties. The following notices apply and are reproduced here as their licenses require.
