The IENE Conference Organizing Committee reviewed over 200 abstracts and devided them into the following types of presentations:

Listen for the crowd noise from Liverpool fans singing "You'll Never Walk Alone." On the 1988 pressing, this is behind the guitar, not on top of it. The dynamic range allows the acoustic guitar’s decay to ring naturally.
In the pantheon of progressive rock, few albums represent a band at a sonic crossroads better than Pink Floyd’s Meddle . Released on October 30, 1971, Meddle sits precariously between the psychedelic wanderings of Atom Heart Mother and the monolithic, dystopian perfection of The Dark Side of the Moon . For audiophiles and digital collectors, one specific version has achieved near-mythical status: the 1988 CD pressing , ripped securely with Exact Audio Copy (EAC) into FLAC format, often tagged with the OA TOP designation.
Do not listen to Echoes on Spotify (their 2016 remaster is dynamically crushed). Do not settle for the 1992 "Shine On" version (which added noise reduction). Find the 1988 West German CD. Rip it with EAC. Compare it with a modern release. The difference is not subtle—it is the difference between a painting and a photocopy. pink floyd meddle 1971 1988 eac flacoa top
"TOP" is more nuanced. In scene release groups, "TOP" can refer to a op S ite release or a "Top Quality" verification. In the context of Meddle , "TOP" indicates that this specific rip has been verified by the community as the best available digital transfer .
That said, the reason the remains a coveted torrent and file-share keyword is simple: Pink Floyd has never officially reissued the 1988 mastering in high-resolution digital. The 2011 "Why Pink Floyd?" Discovery Edition remasters are widely hated by audiophiles for excessive limiting. Until a future box set includes the original flat transfer, the 1988 CD rip remains the gold standard. Conclusion: Why You Should Hunt for This Version If you love Pink Floyd, you owe it to yourself to hear Meddle the way engineers John Leckie and Peter Bown intended in 1971. The 1971 analog master bypassed digital conversion. The 1988 CD captured that master with honest, flat transfer. The EAC secure rip ensured no data loss. The FLAC preserved it losslessly. And the OA TOP tag confirms community trust. Listen for the crowd noise from Liverpool fans
If you own the 1988 Meddle CD—perhaps found in a charity shop or eBay auction for $50+—ripping it for your personal server using EAC to FLAC is your legal right (fair use / backup). Sharing the "OA TOP" version is where legality ends.
At 18:45, when the funky riff returns after the wind section, the 1988 EAC rip retains the tape saturation . It sounds warm, slightly compressed in a musical way, not brick-walled. The bass pedal note at 22:00 is subterranean. If your subwoofer does not shake the room, your FLAC is not the 1988 source. Part 8: Legal & Preservation Note It is important to note that downloading copyrighted music without paying for it violates the law in most jurisdictions. However, audiophiles argue that "bit preservation" is a different mission. Released on October 30, 1971, Meddle sits precariously
In the world of P2P lossless trading (What.CD, REDacted, Oink, Rutracker, Soulseek), "OA" usually stands for . It signifies that this is not a compilation, not a remaster, not a bootleg—it is the exact track listing and mix from the original 1971 release.
