BeatlesNews.com seems to have more detail than any other source I can find on the remasters of the Beatles catalog. I've bullet-pointed some of the most interesting technical details, but I recommend the full article for details.
- Tracks transferred to Pro Tools at 24-bit 192 kHz
- Songs transferred one-at-a-time
- Tape heads cleaned for each song
- Clicks, mic pops, bad edits fixed where possible without harming integrity of recording
- Subtle de-noising, only 5 minutes of music needed this
- Limiting used to increase overall volume of stereo tracks, EMI claims "moderate" use to retain original dynamics
- Limiting not used on mono recordings
- Critcal listening done at Abbey Road studio 3, and another location
Also included, biographies of the engineers who accomplished the remastering.
It is now clear that the main albums will be the original mixes, except Help! and Rubber Soul which will use the 1987 George Martin remixes. I expect that those two albums will see the smallest improvements, as the original analog-to-digital conversions were done in 1987 and then mixed digitially.
WANT! Dying to hear it.
