Owner: RadioTEDU, the student-run radio and media laboratory of TED University in Ankara, Türkiye.

## Purpose

RadioTEDU Technology Lab is an end-to-end media laboratory. It adopts emerging technology early, tests beta capabilities in context, measures their operational value, and documents what reaches production. The editorial thesis is that live radio, podcasts, intelligent discovery and audience participation can coexist in one resilient public media system.

## Technology clusters

1. Broadcast Core: RadioTEDU OnAir, RadioTEDU Smart Audio Switch (RTSAS), shared PCM and measured AAC-LC, HE-AAC v2 and FLAC output tiers, RadioTEDU Focus.
2. Media Intelligence: AI Radio, RTAI Jingle, Situation Room and the RTAI applied media intelligence studio.
3. Participation: RadioTEDU Voting, Juke Local, shared account and Gold economy, Tickets, Hub and Social.
4. Every Surface: mobile and tablet apps, Android Auto, Google Cast, Android TV, Wear OS, system media controls and offline podcasts.
5. Research and Access: academic broadcast-engineering studies and the RadioTEDU Sesli Kütüphane public accessibility initiative.

## Verified production state — 1 September 2026

- RadioTEDU Mobile 1.3.1 (build 13010) passed clean CI checks for TypeScript, tests, Android phone, Android Auto, Android TV, Wear OS and an iOS simulator build.
- Android Auto uses Media3 browsing and playback, branded artwork/icons and assistant-compatible voice search; external products such as Google Maps recognise RadioTEDU through its system media session.
- The persistent website player preserves playback across site navigation and exposes available ICY metadata, catalogue artwork, purchase links and a compact manually scrollable lyrics reader.
- Account and server-authoritative Gold services connect eligible online game rewards, Voting and Social. Juke Local uses a services-PC server with isolated per-kiosk playback and request queues.
- Automated monthly podcast/event newsletters require explicit consent and support language preference, unsubscribe and pre-send preview controls.
- English Technology is canonical at https://radiotedu.com/technology/. Turkish-language browsers use https://radiotedu.com/teknoloji/; other browser languages use English.
