The fractional interpolator works by shifting the phase through a block of
fractionally delayed filters. It rolls over every full sample.
It should be easy to put a method in that will advance this phase. Just add
some mutex around some of the variables.

I'm just looking at the gr_fractional_interpolator, and looks to me like
there's no way to adjust the phase-shift after the block is
instantiated. Is this deliberate?
I have an application where I need to tweak the phase at run-time (not
very often, but I don't want to have to stop, reconfig

I tested the demodulator with similar results. Decoding a file
Hi Josh,
I would be really interested in the uhd versions of benchmark rx and tx as
well.
I came across this code from Andrew back in March.

Please see attachment in the linked email.
Unfortunately I think there are a lot
Hello Mr.Josh
Sorry for replying late.
Thank you very much for you reply.
I would on Linux.The two files I can find in the
/user/local/lib64/python2.6/site-packages/gnuradio/audio are _audio_swig_.la
and _audio_swig.so.I do not any other files in this folder.
