Thanks everybody for all the suggestion!
I think that modyfing an audio card it's the cheapest and more-than-enough
solution at the moment ;-)

Good evening everybody
I'm looking for a sampling device, GNURADIO compatible, with low
sample rate ( max 50 KHz ) AND frequency response down to 1 Hz, so
sound cards aren't the choice.
Any suggestion ???
Tnx in advance :-)

Some time ago I was using Analog Devices' ADALM2000 demo/m
EDN recently published an article on using an external input buffer to
extend the low range response of sounds cards:
“Input buffer and attenuator for sound card oscilloscopes extends low-end
frequency response”. Stephen Woodward.

Besides hardware-hacking a sound card, you may also use some USB
oscilloscope, in combination with sigrok-cli and its --continuous flag.
I have never used this, but I guess there is a way to stream this data
to gnuradio. Note that not every hardware supports this --continuous
feature! Sadly the
For low budget modify the low pass filter of a sound card.

Hi Vittorio,
often you can remove/short the de-coupling caps on soundcards, making
them work down to DC. Maybe thats the easy/simple solution.
Best regards,
