Examples of mastering differences 2014-04-23 11:09:57 In response to discussions on removing duplicates from collections, and discussions about different masterings, I thought I'd start this thread to post some examples of surprisingly large mastering differences.If anyone else is interested, feel free to add your own examples where the sound is significantly different even after level matching (but don't level-match what you post - just straight rips please).Enya - Orinoco flow1st version is from Enya's album Watermark. It's probably the first release of this album (1988). If anyone knows how to ID that for certain, I'll take a look at the actual CD.[attachment=7868:07._Orin...ark_EDIT.mp3]2nd version is from Greatest Hits of the Eighties (3 CD set), released in 1989. It's a different edit (presumably the single edit), but the sound is also completely different. Is this a remix, or just different mastering?[attachment=7869:1-08._Or...ies_EDIT.mp3]Heavy D and the Boyz - Now That We Found Love1st version is from The Greatest Hits of Dance (3 CD set), released in 1992.[attachment=7870:1-02._No...The_EDIT.mp3]2nd version is from Now 1991 (2 CD set, the millennium series), released in 1999. Different EQ, more compression. Same edit and mix (AFAICT).[attachment=7871:1-09._No...991_EDIT.mp3]What amazes me is that I've listened to these versions separately over the years (different times, different stereos, different cars!), and only been vaguely aware of differences in mastering. It wasn't until I listened to them on the same mp3 player or car stereo, days or weeks apart, that I suspected there was something really different - but the differences are dramatic when you listen to them back to back.It makes me even more suspicious of people who claim to have compared audio quality (equipment, mixes, formats, etc) weeks apart in different locations.Cheers,David.
