Demo Download Help
You’ll need to enter a valid email address on this page in order to access the demos.
When an email address is entered, a verification email is sent. Click the link in the verification email to be returned to the demo download page – all downloads on the page will now be accessible (& the email submission box will have disappeared).
If you don’t receive the verification email within five minutes, check your spam folder. If the email isn’t there, refresh the Demo page & re-enter your email address, taking care to ensure its 100% correct. If you still don’t receive the verification email, contact us.
If clicking the link (in the verification email) opens a Demo page where the email submission box is still present, it’s likely because the email address was entered when the page was open in a non-default browser or private (incognito) window. Instead of clicking the verification link, copy the link text & paste it into the exact browser window you were originally using OR open the Demo page in a regular (non-private) window on your default browser & re-enter your email address, so the verification link can return you to the correct page. If you’re still unable to access the demo page content, contact us.

No. The demonstration version cannot be converted into the full version. After purchasing a licence, you’ll receive an email with a download link for the full version of the software. Install the full version, then enter your licence details and activate the software.
No. Once the demo version is downloaded and installed, an Internet connection is not required to use it. You can explore the available features and work with the included sample measurements entirely offline.
You can download demos for as many Eclipse Audio software tools as you like. Simply choose the Windows or macOS version that matches your operating system. You only need to provide your email address once to access all Eclipse Audio demonstration software.
The Product Comparison Table is the easiest way to directly compare Eclipse Audio software features. Demo versions are designed for evaluation, not feature comparison, and some advanced features are disabled. As a result, the differences between the demos don’t always reflect the differences between the licensed products.
The demonstration versions of all Eclipse Audio software have no time limit, allowing you to evaluate the software for as long as you need. They also include pre-loaded sample measurement data and/or project files so you can explore the complete DSP design workflow.
