Sample size always 32768 ?

I am working on an SDR application, using the latest ExtIO. I notice that SDRPlay is always sending my application 32768 samples per frame. Is this parameter configurable ? The 32768 seems at odds with a recent posting in the www.dsprelated.com forum, where a user is reporting an SDRPlay packet size of 336 samples per packet. Perhaps he is using the Mirics API directly, and I am using the ExtIO, which is accumulating the packets before sending the entire frame to the application callback ?

Please explain.

Thanks,
Steve

Hello,

You are right, the number of samples per packet does vary slightly depending on how the RSP is configured, but the EXTIO plugin always buffers the data as per the EXTIO interface requirements.

Best regards,
