Hi Fred,
Yes, when I said 'DAB', I'm talking about Eureka-147, not DAB+ which defines
HE-AAC.
I know that DAB is obsolete, but I would like to use MPEG to create a 'audio
DAB kit' to my students courses.
However, a library allowing to decode all DAB audio formats would be
welcome.
The audio stream that I would like to decode is composed of MPEG frame + PAD
(ancillary data). Of course, I could separate both parts and decode them in
two process.
Because I didn't find API to do this, I think that I will do it my self.
Regards,
Sylvain

When you say 'DAB', I take it you're talking about Eureka-147 datastreams,
not
the 'HD Radio' system in use in the USA? ('Cause HD Radio is not MPEG).
For your information, I'm working with the
FxEngine Framework
(http://www.smprocess.com) on DAB MPEG 1 layer II audio format.
Are these elemental streams? If so, then I assume the PAD is in the
ancillary
channel?
Cheers!
