The members of ABBA and their personnel have memories of the recording sessions for this album being rather difficult. To begin with, their sound engineer Michael Tretow had to become accustomed to using the new 32-track digital recorder that had been purchased for Polar Music Studios. He said, "Digital recording...cut out all the hiss, but it also meant that sounds were sharply cut off below a certain level. The sound simply became too clean, so I had to find ways of compensating for that." The first three tracks for the album had already been recorded using analogue tape and therefore Tretow had to transfer all subsequent tracks from digital to analogue and back again to avoid a difference in quality.
