That's You'd think , but DAB isn't that simple. I'm sure people more in the know can correct me but AFAIK it doesn't simply send 2 channels of data for left and right. I think like FM it sends mono data then some sort of difference data which uses up much less bandwidth so a 128K DAB signal has a mono component of something like (I'm guessing) 100K. I think this is why a lot of people complain about the stereo image of DAB being very flat. I'm sure wikipedia has more info. crystal clear to most people. I listen to 32 K web streams which are great for all but most critical applications. DAB uses the MP2 codec from the late 80s. 32K would be unintelligable. B2003 |
