I'm glad that the "loudness war" in general seems to be over, and people focus more on quality, mixing and mastering rather than making things sound as loud as possible, especially when it comes to electronic music. Similarly as what you said, you know when a mix is very well made when it sounds good when you're playing it on low volume, not when it sounds good on high volume.

Nitpick: the "loudness war" is about mastering / compressing a recording so that it sounds louder at any given volume, it doesn't really have anything to do with optimizing things so they sound better at high volumes or a preference for loud sounding instruments.

I don't know. I'd argue that if the production process is influenced by the loudness war, then it too becomes part of the loudness war.

For example, a technique of masking distortion (or clipping, rather) is adding something with rich harmonic content (a trumpet for example) to parts that are expected to be hitting the wall and otherwise distorting / clipping.

Would trumpets be there otherwise? I don't know, but I'm sure producers are aware of the limitations of digital audio and as such adapt the music to it.

I worked as a mastering engineer for a couple years back in the aughts, and I can confirm that to really max things out requires production techniques.

For example, analog tape naturally saturates high frequency sounds before low frequency sounds, which brings down the peak level of a close mic'd drum. Peak limiting a recording which already has analog-saturated drums produces fewer audible artifacts.

In the abstract, at mastering-time you can achieve any absolute level without hard-clipping by smushing down the peaks with peak limiting and multi-band compression, then dialing things back up with makeup gain. But when compared against the original recording in a level matched test, at some point the processed result becomes unacceptably degraded.

It's hard to make things louder when your loudest section tops out.

Compression is an optimization for making the song sound better at louder volume

To my mind it's the other way around. A "loud" recording with little dynamics sounds OK at lower volume; the listening fatigue sets in when the volume is increased. A dynamic recording, on the other hand, often sounds great when you turn up the volume and can really hear the difference between soft and loud sounds.

The difference is the delivery medium. It has always been in the interest of producers for individual recordings to seem louder relative to other recordings in the same genre, and that is still true today. However, a level matched experience is better for the consumer, so apps like Spotify apply perceptual loudness metrics and turn down maxed recordings.

That kind of level matching didn't happen with consumer CD players or vinyl turntables. Producers have to use different techniques to stand out in an automatically level-matched environment.
