11. FAQ

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

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. Qobuz, Tidal and HIGHRESAUDIO browsing in the Library requires an active subscription to each respective service. Everything else works without any third-party subscription.

Does it work without an internet connection?

Audio playback runs entirely on your local network — no cloud, no telemetry. However, licence activation and periodic validation require access to the licence server, and Qobuz, Tidal and HIGHRESAUDIO require an active internet connection for streaming.

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?

All v1.x updates are included with the Pro licence. 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, always up to date) and online.

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.
