Hello!
I am current transmitting an audio stream from my sound card (SB Audigy2) to
the USRP and it is transmitting at an FM frequency. The problem I am facing is
that my sound card supports 44100Hz sample rate however, since the USRP audio
rate is an integer factor of 128MS/s When I receive the signal on a regular FM
radio it sounds funny depending on the audio rate I set (either sounds high
pitched if i set audio rate to high or sounds low pitched and slow if I choose
a lower sample rate).
If I change the sample rate for the audio_source (sound card) it gives me an
error that the sound card requests 44100Hz.
I am including the lines I am using to rectrieve the audio data:
" self.fg = gr.flow_graph()
src = audio.source(44100, options.audio_input)
fmtx = blks.wfm_tx(self.fg, self.audio_rate, self.usrp_rate)
self.fg.connect(src, fmtx, gain, self.u)"
Thank you for the previous help and Thanks for this one in advance.
Omer
