Almost. Translate the carrier to where you want it to be and then use a
complex bandpass filter to pick off the sideband.
make the filter edges L < H for your favorite bandwidth (H-L)
for USB, make a complex filter with edges L, H
for LSB, make a complex band pass filter with edges
-H, -L
Take the real part, make imaginary part = real part.
send complex signal to sound card.
If you do not make imaginary part = real part you will get "binaural"

Hello, I have made my first attempt at gnuradio and usrp today, trying
to get a phasing ssb demod - what follows is what I got, any suggestion
would be more than welcome. The demod is designed as a class to be
istantiated by a gui (i am using a modified version of usrp_wfm_rcv
gui). Right now the only sideband supported is LSB. Tested with the
basic rx and my 40m vertical attached, it behaves nicely.

Since the usrp gives you complex baseband, there's really no reason
for a phasing demod, just translate the signal to where you want it.
