How brilliant it is when you don't have to get a "dusty, half-empty guest book" out of the cupboard years later, but instead can fully reproduce the voices of the guests, the atmosphere on site, the emotions and the energy - all the voices! Those of your own parents, grandparents, friends or even your little niece, who perhaps couldn't even write at the time of the party.
Her voice will also change over time. How nice it is to have the opportunity to preserve the sound of their voice at the time of the event. Other voices will unfortunately fade away because they have left us forever. A message left by a loved one in the audio guestbook can be one of the last recordings of their voice that a couple has.
