A two-minute demonstration of the loudness war, showing how heavy dynamic range compression in CD mastering makes music louder while degrading sound quality. It uses audio examples so you can hear the distortion.

HN keeps linking it as the shortest clear explanation of over-compression and brickwalled mastering.

Your post led me down the rabbit hole of over-compression, not for the first time, and I ended up at this video which gave a very succinct answer to my question of: "Okay, I realize that music is getting compressed, but what are we losing?" ▶ this video Via a nice article with analysis: link

The same reason why music on the radio is so dang loud– excessive compression. See: The Loudness War (just 1:54 mins long): ▶ this video

I think one of the reasons that those people who prefer vinyl over digital do so, is that the recordings on vinyl are mastered with different qualities in mind than their digital counterparts. There's a YouTube video floating around called The Loudness War ( ▶ this video ) that describes what I'm talking about. I distinctly remember albums on audio CDs sounding better to me (great clarity, vibrancy, etc.) back in the early 1990s. Then, somewhere toward the end of the 1990s, CDs just started to sound worse. I blame the trend described in that video. I suspect that vinyl recordings do not suffer from this same tendency toward loudness in the audio mastering process, and that is why you have audiophiles insisting that vinyl sounds better than digital.

And now we have the Loudness War where the songs are so highly compressed that there is no dynamic range. Because of this, I have to reduce the volume so it isn't painful to listen to. And this makes what should have been a live recording with interesting sound into background noise. Example: ▶ this video If you want a recent-ish album to listen to that has good sound, try Daft Punk's Random Access Memories (which won the Best Engineered Album Grammy award in 2014). Or anything engineered by Alan Parsons (he's in this list many times) link

”The same thoughtless disregard for basic music fundamentals that plagued the preliminary edits ended up on the final OST.” As a musician and music-lover, seeing how they brickwalled [1][2] Mick’s tracks in the screenshots only serves to add to the heartbreak of his entire saga.
