11. FAQ

Quick answers to the questions we hear most. Each one links to the chapter that covers the full story.

What does “Public beta” mean?

That the V1 scope is complete: every feature described exists and runs today — nothing here is a mock-up or a roadmap item. What remains is correction, refinement and optimisation, not missing features. Bugs do turn up, and they get fixed — report anything you hit.

What happens after the 30-day trial?

The Starter Edition activates automatically — no action required. You keep full access to all Starter features indefinitely, for free. Pro features are locked until you purchase a licence (see 7. Administration → Licence).

Does it work without Roon?

Yes. MPD alone is enough for the Starter Edition. Roon, HQPlayer, upmpdcli, Shairport-Sync and AirPlay are all optional — install whichever you want in one click from the Audio Software tab, and Audiogravi^ty manages them from there (configuration, tuning, orchestration). See 3. First run.

Do I need a Qobuz, Tidal or HIGHRESAUDIO subscription?

Only if you want to use those services, and everything else works without any third-party subscription.

To listen to them in full, yes: each needs its own active subscription. Browsing is another matter — Qobuz and Tidal let a lapsed account sign in and browse the whole catalogue, and play thirty seconds of each track; HIGHRESAUDIO refuses the catalogue but still plays what you bought from it. The sources card names the state in each case, so short tracks are never a mystery. See 5. Library & streaming.

Does it work without an internet connection?

Audio playback runs entirely on your local network — no cloud, no telemetry. Your licence keeps working offline too: whether Pro is unlocked is decided on the box, from the signature of your licence file, so a box that never reaches the internet again keeps every feature it had. What does need the internet: activating a licence in the first place, the daily check-in that carries announcements and update offers, and streaming from Qobuz, Tidal or HIGHRESAUDIO.

Can I use one licence on multiple machines?

No. A Pro licence is bound to one installation. If you move to a new machine, a licence reset is available on request — contact us at [email protected].

Are updates included?

Yes, on every edition: the trial, Starter and Pro all receive the updates of their major version (v1.x). Pro holders receive a preferential upgrade price for future major versions.

How do I install Audiogravi^ty on my phone?

Audiogravi^ty is a Progressive Web App — it installs from the browser, no app store needed. On iOS: open Safari, navigate to your Audiogravi^ty URL, tap Share → Add to Home Screen. On Android: open Chrome, tap the three-dot menu → Install app. It then runs fullscreen with its own icon, just like a native app — and on iOS the installed app is what enables push notifications. Note: on iOS, only Safari supports PWA installation. See 3. First run.

How do I connect Qobuz, Tidal or HIGHRESAUDIO?

All three connect from Library → Sources: open the service's card and tap Connect. Qobuz signs in and redirects back automatically. Tidal lands on a fixed URL that a web app can't intercept — copy that full URL from the address bar, paste it back into the Tidal card and tap Finish login, once. HIGHRESAUDIO is simpler: enter your account email and password directly in its card. Tokens are then stored and refreshed for you. The full walkthroughs are in 5. Library & streaming.

Where is the documentation?

A fully illustrated manual covers the whole journey — from installation to troubleshooting — with a one-page quick start and a glossary. It is readable inside the app (the Manual tab — the manual of the version your box runs, even without internet access) and online, where the latest edition is published.

How do I update Audiogravi^ty?

From the interface. When a new release is available, the Admin tab shows an update banner — one click and your admin password, and the box downloads, installs and health-checks the new version with live progress. If anything goes wrong it automatically rolls back to the previous version. No terminal, no re-running the installer. See 8. Updating.
