From Wikipedia article on the "Beatles 1" CD:
"According to the liner notes of the album, the original analogue masters were "digitally remastered at 24 bits resolution, processed using Sonic Solutions NoNoise technology and mastered to 16 bit using Prism SNS Noise Shaping." The remastering was overseen by Peter Mew of Abbey Road Studios and took place there."
