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I know that DAB is obsolete, but I would like to use MPEG to create a 'audio 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
