Re: [Discuss-gnuradio] Basic Microphone Integration

[Martin Braun]

The audio sinks do that; you might have to use your OS's mixer settings 
for selecting the mic.

The audio sink/source are like the UHD blocks in that you pipe in 
floats, and 1 maps to FS. So keep your abs value below 1 and you're good.

gr-audio has some examples for you to peruse.
