Audio Source GNU in windows 10

Recommended Posts


 I am using GNU Radio 3.7 on windows 10 platform.  To begin GNU radio I started using blocks such as Signal source and Sinks.

I have taken a wav file source passed through a throttle and connected sink to it. I am able to see behavior and FFT of the source.

When I replaced the wav file source with the audio source and kept device name blank Sink block doesn't show anything. 

Has anyone faced this issue.

I tried to check my audio reception and transmission is working, I wrote python script to record voice from mic and send of speaker to listen. It is working fine.

Now I wanted to add embedded python block, but when I open it in a editor a blank file open and if I write something in it, it wont save it.


Reply will be appreciated.
