Audio quality of different Internet-Radio Systems
at different Modem Speeds


On the following pages you can compare the most popular audio@internet coding systems. They were tested at modem speeds of 28.8 kbps, 56 kbps as well as with ISDN, DUAL ISDN and DSL. For the tests critical material in mono and stereo are used. With @ida you can now form an opinion about the quality of the different systems. All of the encoded files were converted in wav format for your convenience, requiring the use of just one of the standard players listed below.
The IRT (Institut für Rundfunktechnik) is currently involved in testing these systems within the framework of the EBU "Audio in Multimedia" Projekt Group.
