Today I tripped over a software for decoding DAB and FM which I've compiled successfully on my Ubuntu and surprisingly it supports the sdrplay.
Very nice, compared to the RTL stick I also have, the SN/R is some dBs better with sdrplay. For me the first Linux program which supports the sdrplay. If someone is interested it can be find here: http://www.sdr-j.tk
Mind you as with everything that is 'free' it's a work in progress so feedback will help in it's development.
There are no miracles .
Sdr-j-dab-receiver takes data stream almost raw (using RTL2832 in debug mode, mode discovered by hackers and info cast into osmocom rtl library) and it does all the work.
Quite good work I must say.
