The 2011 remastering of "The Ultimate Best Of" involved a thorough re-examination of the original recordings to ensure that they sounded their best on modern playback systems. The remastering process involved using high-resolution digital transfers of the original analog master tapes, followed by careful equalization, compression, and limiting to optimize the sound for digital playback. The 320 kbps version, in particular, offers a high-quality digital representation of the music, with a good balance between file size and audio fidelity.
