This is comparing Doom 2016 with Doom Eternal. It shows strange production in Doom Eternal that is very probably an error (overlapping without crossfade), but it provides no additional information as to why the Doom Eternal OST has low dynamic range.
In the tweet, the waveform image on the left is Mick’s original “BFG Division” track from the Doom 2016 OST.
In the same tweet, the waveform image on the right is Chad’s edited version of Mick’s track for the Doom Eternal OST, entitled “BFG Division 2020.”
The comparison is valid, because it is Mick’s music, and it also serves to demonstrate the audio engineering expertise on the Doom 2016 OST, which was hailed as a masterwork soundtrack in the genre.
However, Mick did not mix this particular track for the Doom Eternal OST, and this is the critical point of this specific waveform comparison; that is, as Mick expresses in the article (and the waveform comparison demonstrates), the Doom Eternal OST is not entirely representative of his actual work, or the full depth of his audio engineering expertise.
This is due to decisions and modifications that were made without his input (e.g., the aforementioned editing).
