Antonio,

Unless you have a 192 KHz sampling audio card, the frequency is too high 
for direct decoding.

You can get low-cost receivers for both the UK (MSF) and German (DCF77) 
VLF transmitters.  One write-up is here:

  http://www.buzzard.me.uk/jonathan/radioclock.html

which mentions a Conrad 641138-92 module, and offers part for UK 
residents.

Quite honestly, if time is your only interest, for the cost it's as cheap 
to get a low-cost GPS receiver board such as those mentioned elsewhere on 
the list.
