Internet radio — what it is, how it works, and where to listen

What is internet radio?

Internet radio (also called webradio, online radio or streaming radio) is radio where the audio signal is delivered as a digital stream over the internet. A listener connects to the station's streaming server via a browser, app, or smart device — similar to opening a YouTube video, but with continuous live audio instead of a fixed clip.

Unlike classic radio, internet radio isn't tied to a local FM transmitter or DAB+ multiplex. A Dutch station can be played from Australia, as long as you have internet access. Many terrestrial broadcasters (BBC Radio 1, Antenne Bayern, RAI Radio 1) offer the same programme on FM/DAB+ and online. There are also tens of thousands of internet-only stations: small themed channels, regional projects, community radios that exist only online.

How does it work technically?

An internet-radio station has an encoder that compresses the audio (usually MP3, AAC or Ogg Vorbis) and sends it to a streaming server (Icecast, Shoutcast, or a commercial provider like Streamtheworld). That server fans the same stream out to every connected listener at once. The listener's app or browser receives the continuously incoming audio packets and plays them back immediately.

Typical bitrates are 64-320 kilobits per second. 64 kbps suffices for talk; 128 kbps gives decent music quality; 192-320 kbps reaches studio quality. One hour of listening at 128 kbps uses roughly 58 MB of data. For broadcasters, internet radio is attractive because startup costs are minimal — a server and bandwidth are all you need, no transmission tower.

Difference from FM, AM and DAB+

Internet radio is one of three modern radio distribution forms, alongside legacy analogue FM/AM and digital DAB+. Key differences:

• FM/AM: Analogue, antenna-based, free reception without a data subscription, but geographically limited and prone to interference. AM has largely disappeared in Europe; FM remains popular but its sound quality is lower than digital.
• DAB+: Digital terrestrial radio with better quality than FM, a wider selection, and free reception. Requires a DAB+ receiver. Most Western European countries have good coverage; rollout in parts of Eastern Europe is more limited.
• Internet radio: Worldwide reception of any station broadcasting online, on any device with an internet connection. Needs data (mobile or WiFi) but unlocks thousands of stations beyond your own country.

Advantages of internet radio

• Worldwide reach — listen to any station from any country. An Italian jazz station while in Amsterdam? No problem.
• Thousands of niches — themed channels that would never make economic sense on FM (Bach only, 90s house only, Faroese folk only).
• Low barrier to entry — a community radio can start with €30/month of server rental, which is why the field is so diverse.
• No dedicated radio device — phone, laptop, smart speaker, car Bluetooth all work.
• Better sound quality than FM/AM at higher bitrates. No airwave interference, no tunnel dropouts (assuming you have 4G/5G or WiFi).

Brief history

The earliest internet-radio experiments date from 1993-94, when Internet Talk Radio and WXYC (the first regular FM station to also stream online) began broadcasting via RealAudio and early MP3 encodings. The late 1990s saw an explosion of supply with Shoutcast (1999), a free tool that let anyone run an internet station from a bedroom. Through the 2000s, large aggregator sites emerged (TuneIn, Streema, Radio-Browser.info) and worldwide station counts grew to tens of thousands. Today internet radio is a mature distribution channel alongside FM and DAB+, with many stations existing only online.

How do you listen?

The barrier is low: any modern browser (Firefox, Chrome, Safari, Edge) can play an audio stream directly. Open an aggregator site like dabplus.live, pick a country or search by name, click a station, and you're listening. On mobile it works the same way — no app needed. In the car: connect your phone via Bluetooth or CarPlay/Android Auto. Smart speakers (Sonos, Google Home, Amazon Echo) can also play stream URLs directly.
