Radio is alive.
And it's already funded.

Yes. The site is a fully static page with no backend, no accounts, no first-party cookies and no analytics. Audio processing runs entirely in your browser via the Web Audio API, and nothing is persisted between visits. The only external connections are the radio stream you choose, the optional local AI model (only if you enable ad-muting and the model is deployed) and the anonymous A-ads frame.

Because radio is already paid for: public broadcasters are funded from taxes, commercial stations from advertising and music-licence fees. This player adds adaptive studio-grade processing to those free streams, so you can skip another monthly bill, avoid an account and keep your listening habits private. A well-encoded station (256–320 kbps AAC/MP3 or FLAC) matches a standard subscription stream, and the adaptive expander plus parallel exciter restore much of what broadcast compression removes.

No. Processing cannot recover frequencies the codec already discarded. The adaptive expander restores dynamics that broadcast compression flattened and the parallel exciter adds harmonics so lossy highs feel restored, but a 320 kbps or FLAC stream always carries more real detail than 128 kbps. For best results choose the highest-quality stream a station offers.

Yes, within a deliberately clean path: Advanced mode exposes the same parameters the adaptive engine uses — input and output gain, expander ratio, exciter drive and frequency, auto-volume target and tube amount. There is no EQ by design: tone shaping belongs in the correction built into your speakers or headphones.

Nothing is uploaded. A 101 KB classifier runs locally: the browser computes log-mel features from the stream tap, scores 3-second windows with ONNX Runtime and mutes above a calibrated threshold. On our held-out evaluation (1,500 Internet Archive clips) it caught 97% of ad clips at 90% precision — so roughly one in ten detections is music. It is off by default, FORCE UNMUTE always overrides it, and no audio or features are stored or transmitted.

Nothing personal. The player keeps no settings or history: the only client-side storage is a service-worker cache of the app's own files. There is no account, no cookie, no analytics, and nothing is uploaded or synced.

The privacy policy lists every external request the player can make.

Not this edition. Playing radio or licensed music in a business generally needs a licence from your local collecting society (Buma/Stemra, SABAM/PlayRight, GEMA or the equivalent) and unlicensed public performance can be fined.

Use the High Fidelity Pure Business edition, which is built around royalty-free music, and still verify each source's licence. See terms & disclaimers.

Browsers enforce CORS: a stream server must explicitly allow web pages to play it. Streams that refuse cross-origin playback cannot be processed by the Web Audio API at all; some are also geo-blocked or offline. Pick a stream that allows it — the ones listed here do.

No. It is a website, so it works in any modern browser with no install at all. On a phone or tablet you can add it to your home screen as a PWA (installable, works offline for the app shell), and the same build runs on smart-TVs and hi-fi streamers with a browser engine — webOS, Tizen, Titan OS, Sonos, HEOS and Bluesound. There is no sign-up, no account and no app-store approval.

The site is served from Berlin, Germany (EU) by Codeberg Pages, a volunteer-run non-profit that runs its own hardware and avoids large cloud providers where possible. The build is fully static, so no server processes your requests. Codeberg does not publish a verifiable renewable-energy figure for its facility, so we do not claim to be 100% green. The radio streams are hosted by third-party broadcasters and CDNs that may be outside the EU and may not use renewable energy — we cannot verify or control that.

See the hosting & privacy section.

No. Nothing you do is sent to us because there is no "us" — there is no server. The stream URL stays in your browser, settings are never persisted, and the only third-party network calls are the stream host and the anonymous ad frame.
