Re: [Discuss-gnuradio] No audio on os x reading .dat files

[Michael Dickens]

Josh - I'm downloading one of the .dat files from kd7lmo, but that's  
sort of slow ;-)

In the mean time, let's get a bit of background on your setup.  Which  
Mac hardware & OS version?

Any reasonably modern Mac should be able to deal OK with the filters  
and audio involved.  That's all done in single-precision floating  
point ("float").

The .dat format is complex<float>, meaning 2 floats per item (one  
"real" or "in phase", and the other "imaginary" or "in quadrature").

Given that PortAudio can handle the audio, gr-audio-osx should be  
able to as well.  But it doesn't work for me either (the file  
finished downloading) ... so clearly there's something odd going on.   
I will investigate this over the coming weekend, and will get this  
issue resolved as quickly as I can put time into it ... got lots on  
my plate already.

As for "getting this running", we will certainly get .dat files  
running on gr-audio-osx, just be patient.  It might take a few  
iterations and a couple of weeks to sort this out; really depends on  
the issue. - MLD
