Re: [Discuss-gnuradio] Audio transmitting question

Hi Timur,

I’m not sure if this is your main problem, but we generally don’t recommend using a Throttle block with hardware sources or sinks.  Instead, the hardware alone should control the sample rate.  It is plausible that your Throttle block is preventing the "osmocom Sink" from getting samples quickly enough.

Hi Marcus,
Please find attached Screenshots of (tx/rx) flowgraphs that I used to transfer the file.
Without Codecs. The sound lasts well for several tens of seconds, then errors are heard. I'm transmitting the wav file with 8 KHz Samplerate.

I hope you can help in this matter. Looking forward to receiving your reply. Thank you.

Hi Timur,

there's infinitely many things that can go wrong – this might be a
design mistake, this might be device imperfections, or this might
really just be noise on your wireless channel.

So, without you posting all details about your transmitter/receiver
implementation, this will be pretty impossible to answer!

Looking forward to more info,
Regards,
Marcus
