Pre-release
Beta programme.
A small group of engineers gets XRB Audio builds before they launch and tells us what breaks. You register, apply once, and a person reads your application. Once you're in, you get a time-limited key for each product that has a beta build — by email, and in your account.
How it works
- Sign in — that's your XRB Audio account. We never see a password.
- Apply below. It takes a minute, and you accept the evaluation agreement.
- We review it by hand and email you either way.
- Approved testers get a 60-day key for each product with a beta build, emailed to them and listed in their account next to the download.
What's in beta
XRB IsoVoxBeta build open
XRB LinDynBeta build open
Apply whenever you like — approved testers get a key for each product the moment its beta build opens.
The short version of the agreement
- It's unfinished software — keep it off anything you can't afford to have go wrong.
- Keep the builds to yourself, and don't post about them until launch.
- Keys expire. XRB IsoVox's Mac app and Audio Unit then pass your audio through unprocessed; XRB LinDyn goes silent. If you're still testing we'll extend the key, and you re-activate it to pick up the new date.
- Tell us what breaks. That's the whole point.
The full text is the evaluation agreement (version 2026-10-v1).
