Web Radio FAQ: How Does This Technology Work?

Web radio—more commonly referred to as internet radio—is a technology that continuously transmits streaming audio over the internet to your computer. This technique of broadcasting audio using data transmission is much like listening to terrestrial radio.

Traditional radio stations simulcast their programs using one of the compatible audio formats that internet radio uses such as MP3, OGG, WMA, RA, AAC Plus and others. Most up-to-date software media players can play streaming audio using these popular formats.

Traditional radio stations are limited by the power of their station's transmitter and the available broadcast options. They might be heard for 100 miles, but not much further, and they may have to share the airwaves with other local radio stations.

Internet radio stations don't have these limitations, so you can listen to any internet radio station anywhere you can get online. In addition, internet radio stations are not limited to audio transmissions. They have the option to share graphics, photos, and links with their listeners and to form chat rooms or message boards.

The most obvious benefit of using web radio is access to thousands of radio stations that you wouldn’t normally be able to listen to due to your locale. Another advantage is an almost unlimited supply of music, live events and radio show that you can listen to in real time. This on-demand audio technology gives you access to entertainment at any time of the day without having to first download files to your hard drive.
