Re: [Discuss-gnuradio] Is there any way to obtain the binary output from audio source

Do you just mean having the actual samples? Take a look at usrp_rx_cfile.py. It uses gr.filesource_sink (or whatever it's called), with a bunch of settings. From your description, it should be exactly what you want.

Hi all,

I was wondering if there is anyway to obtain the binary output from audio source in GRC. I need this bits information as modulating signal for ASK. Since sound card digitized our analog voice signal to binary information in 16bits (suppose the sound card is 16bits), so I think it should be a way to directly obtain the 16bits binary output of each float symbol from audio source. I used to digitize them through "float to byte" type conversion, however, it would lost a lot of dynamic range since byte is only 8bits which is too imprecision.

I've been confused by this question for a long time. Is there anybody who can help me? Thank you in advance!

Milo
