Over at the Hydrogen forum, some of the members discovered the 24/96 waves were actually 16bit padded out to 24bit. So they let Trent Reznor and the NIN community know about it on or about May 7th. The NIN camp, surprisingly, responded back on the 8th. They said they were sorry for the mix up, would correct the problem and re-post the waves. Well, on the 14th, they re-posted the 24/96 waves and in addition 24/96 FLAC files. Let it never be said Mr. Reznor is not a standup guy. Here is a copy of his statement on the Hydrogen forum from the 14th.
Thanks for the heads up regarding this matter. The corrected files are now posted on our site and if you re-download them they will be the correct ones.
What happened? We mastered this on Friday (5/2) and released it Sunday night. The files went right from mastering to the server without the proper scrutiny (aside from a cursory listen for errors). The last two songs were different because they were redone due to an audible error we did find.
Bottom line: some sort of mastering shenanigans took place.
In addition, there are now 24/96 FLAC files as well as wave files.
BTW, the record was recorded at 24/96 using a Lavry AD122-96MKIII, Antelope's Isochrone OCX clock and mixed in analog through the SSL AWS 900+. We mixed back into Pro Tools through the Lavry as well as a separate rig running at 24/192 using Apogee A/D. The mixes we chose varied song to song based on what sounded best to us.
