Re: [Discuss-gnuradio] sound card as complex source ?

[Johannes Demel]

Hi JM,

the audio source block has an option 'number of outputs'. I assume you 
need to configure your audio source to choose the correct device and the 
correct number of output streams. I guess what you want is, you 
interpret source0 as I and source1 as Q data. Then use float to complex 
to interleave them.

Cheers
Johannes
