Hey guys!
I bought this vinyl when it came out, and just recently decided to compare the digital download that it came with to the Rush Remasters version I had on CD, and I discovered that the new digital download tracks were shorter and ran slightly faster than the CD version (and as a result, were very slightly sharper in pitch). I checked the track lengths and compared it, and sure enough, the digital download for the title track, for example, ended up being a whole 17 seconds shorter than the CD version (20:34 for the CD version and 20:17 for the digital download. The wikipedia page for the album lists the track length as 20:34). I've also compared the vinyl itself, and the audio on it is also faster and slightly higher pitched although to a slightly lower extent than the digital download.
The pitch difference ends up being significantly less than a semitone, so to me, it wasn't perceivable until I was comparing the digital files just to see how much of a difference there was.
So yeah, this whole thing really perplexed me. Is this common with analog audio formats? And what are the chances that things like this can throw off my own ear training when it comes to pitch accuracy?
