Audio rate and quadrature rate in gnuradio

Hello everyone,

Hello everyone,

   I'am building an FM transmitter in gnuradio .Well the audio wave

file is connected to wbfm transmitter through resampler block.The audio
sample rate is 48KHZ and according to the wbfm block the quadrature rate
and audio rate are related by mod function (quad_rate % audio_rate=0)
so
i’m setting the output sample rate to the multiplies of 48 but when i
set
the audio rate and quad rate equal i’m able listen properly to the
transmitted audio file.If it is set to different values i’m hearing alot
of
noise and sometimes samples running very fast or very slow

I’m using the usrp b100 instant kit
Awaiting for the valuable reply

Thanks and regards
Sandhya
