aacPlus to replace MP3 streams

Old fashioned radio

Slate has an interesting article on how aacPlus is going to replace MP3 streams in the near future. The main reason for this being the small bandwidth requirements for aacPlus (48kpbs will get you decent stereo sound). An excerpt from the article:


It's a given that fat broadband lines are the future of online media. But right now, for Internet radio, the future is about slimming down—creating skinny little streams of data that don't eat up too much bandwidth. The key is a new and better audio compression format called aacPlus, or sometimes HE-AAC, which has been chosen by the industry committee that standardized MP3 13 years ago (the Motion Picture Experts Group). If you've tried to listen to online stations, you know they sound grainy if they're streamed at any less than 128 kilobits per second—maybe 96 kbps if you're not fussy. That makes a broadband connection a must. But aacPlus sounds nearly as good as a CD, even when it's compressed enough to play through a dialup line. Don't take my word for it—see the results of the European Broadcasting Union's listener tests, in which aacPlus was deemed the "clear winner" at a dialup-friendly 48 kbps.


There could be something to this. After all, aacPlus is already used by XM satellite radio, and the smaller bandwidth needs will make these streams more viable cost wise. Also people with cable connections will be able to serve up more streams.

This can only lead to good things. For an example of aacPlus streams check out tuner2.com.
