==Different masters==
The album was made available in three two different masters for digital download: a "standard" version, and an "Audiophile Mastered Version" and a master specific to the high resolution HDtracks service (the latter two having extended dynamic range, and not meant to be competitive in the loudness war.) An explanation was posted on the official NIN tumblr account:[http://nineinchnails.tumblr.com/post/59587808317/hesitation-marks-was-mastered-in-two-different]
<blockquote>''Hesitation Marks'' was mastered in two different ways - the standard, “loud” mastering (which is what you’ll find on the CD, on iTunes, and everywhere else), and also an alternate “audiophile” mastering, which we’re offering as a free download option for anyone who purchases the album through [[nin.com]]. For the majority of people, the standard version will be preferable and differences will be difficult to detect. Audiophiles with high-end equipment and an understanding of the mastering process might prefer the alternate version.
