We do more than use broadcast technology.
We build it too.
RadioTEDU is a student-led media lab building broadcast infrastructure, open-source software, artificial intelligence, interactive campus products and new listening experiences.
Our technologies
More than broadcasting
a technology system.
Every project answers a real need: to focus, discover, vote, work together or carry radio to every screen.
Focus
A distraction-free listening space.
A focus-first listening experience that brings Lo-Fi, Jazz and Classical streams together with a Pomodoro timer, nature sounds and a calm interface.
- Themed live channels
- Pomodoro and nature sounds
- Ready for mobile and desktop
Autonomous AI radio
AI radio that understands the flow of the broadcast.
rtAI uses live track data, station identity and broadcast context to build an autonomous radio flow. Open-source and local models turn AI from a showcase into real broadcast infrastructure. Between songs, an AI host considers the current track, what comes next and the station tone to create natural announcements.
- Live broadcast and track data
- Context-aware AI host speaking between songs
- Announcements, programme information and natural transitions
- Open-source, local-model approach
Global news-density map
RadioTEDU Situation Room reads the news through a 3D globe.
RadioTEDU Situation Room brings together RSS feeds from international news, public-service and humanitarian sources every two hours. It presents concise source-grounded AI summaries, country-level news density and the Situation Room live stream in one focused interface.
- 15 verified international RSS sources
- One-click access to the original source for every report
- Country density rendered from dark grey to RadioTEDU red
- Integrated RadioTEDU Situation Room live stream player
Local AI voice studio
Human-like voice, ready for broadcast.
RTAI Jingle turns your script into natural narration with local QwenTTS, balances music automatically beneath the voice and produces broadcast-ready jingles. It works without an account, telemetry or a cloud narration service.
- Multilingual voice generation, including Turkish
- Tone, warmth, energy and pace controls
- Automatic music ducking and broadcast-level mastering
- 48 kHz MP3 and 24-bit WAV output

RadioTEDU-OnAir-New is the separate playout and broadcast automation application. Its runtime prepares HE-AAC and FLAC outputs for Icecast and an HLS-ready delivery path, then sends the programmed broadcast to the server layer.
- Radio playout and broadcast automation
- HE-AAC and FLAC output pipelines
- Icecast delivery with an HLS-ready runtime

Broadcast encoding
Fraunhofer HE-AAC v2, AAC-LC and FLAC
RadioTEDU uses ITU-R BS.1770-5 loudness and true-peak measurement with the EBU R128 broadcast reference. Streams are encoded by our internally compiled, non-distributed FFmpeg build using Fraunhofer FDK AAC: HE-AAC v2 for efficient low-bitrate delivery and AAC-LC at 192 kbit/s for full-quality listening. Classical and Jazz are also available in lossless FLAC. See our Technology page for more.
HE-AAC v2 prioritises efficient delivery for constrained-bitrate quality profiles. AAC-LC is used where a profile can allocate more bandwidth to stereo detail and listening continuity, while the Classic and Jazz FLAC options preserve the lossless master signal.

Volunteer audio library project
A library recorded together for children with visual impairments.
Audio Library is a collaborative production space where volunteers record books in the browser, edit them chapter by chapter, run quality control and submit them for approval. Its goal is to build an accessible audiobook collection for children with visual impairments.
- Book, recording-task and volunteer-lead management
- In-browser recording, waveform editing, trimming, muting and level adjustment
- Editor queue, re-recording, quality control and approval workflow
- Audiobook archive import and library publishing
Related goals: access to quality education, reduced inequalities and volunteer partnerships.

Technology is not just a delivery tool; it is our production space.
RadioTEDU students work with real-world media infrastructure, software development, product design, artificial intelligence and community technologies.
The result is more than broadcasting: working products that shape campus life, grow open-source culture and become part of a student portfolio.
