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 next-generation 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
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

Live voting
The listener chooses the next song.
The live Voting system connects candidate tracks to the broadcast flow and collects votes in real time. When the countdown ends, the community choice becomes the next song on air.
- Real-time candidate and vote data
- Round-based countdown
- Experience integrated with the mobile app
Mobilee app

Live channels, podcasts, rtAI, Voting, Study, games, profiles and the Gold system come together in one mobile experience. Background playback and system media controls make radio a natural part of the day.
- Live radio and podcast library
- Study, Voting, games and Gold
- Notifications, lock-screen and Bluetooth controls
Jukebox
The digital jukebox for shared spaces.
The QR-enabled Jukebox lets students join the music flow around campus. Requests, queues and device management bring physical spaces and digital broadcast infrastructure into one system.
- Quick access with QR
- Queue and device management
- Streams tailored to campus spaces
RTSAS · Icecast / SHOUTcast server

RadioTEDU OnAir · Broadcast automation
OnAir runs the radio automation.
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 streams high-efficiency audio encoded with an internally compiled, non-distributed build of FFmpeg using Fraunhofer HE-AAC v2 for efficient bitrate, AAC-LC for listening experience, with Classic and Jazz streams also available in master-quality 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.

- 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

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.
