FOR A NON-AGRESSIVE and RESPECTFUL AUDIO MASTERING! (2)

The MIXING source

The analysis of the file shows us a regular progression of the average level (RMS) via 3 steps (beginning, middle, end), from ≈ -26 dB to ≈ -14 dB, that is to say 12 dB of difference between the beginning and the end of the song.

The "current" MASTERING

We find the same progression of the average level (RMS) - in 3 steps - from ≈ -17 dB to ≈ -6 dB, or 11 dB difference between the beginning and the end of the song.

Very surprising: the gain of +1 dB is without real interest. Only the "global" average level went from ≈ -17 to ≈ -9 dB, that is to say a "displacement" of +8 dB, which would have been strictly the same if you had simply turned up the listening volume !

Nothing very annoying in itself ... except that this +8 dB gain was achieved at the expense of the quality of the music, because there was only 2 dB of margin (peak vs 0 dBFS) on the mix file.

How this gain of ≈ +8dB has been realized ? ... by a strong limitation of peaks (see other article here).

How is this negative? If there had been very few peaks, the audible impact would have been imperceptible. Unfortunately, for this third part of the song (≈ 1/3 or about 1 min) it represents a good part of the useful signal! So, the limitation applied "cuts off" the necessary musical information from the « intense » moment, and as a direct consequence on the "imprecise-aggressive" side that we find in a comparative listening [ Mastering source (same RMS level as the mix) ].

To quickly illustrate the damage, you can also listen to the "muted" signal [ Signal removed trought Peak Limitation Mastering ]. This is far from negligible !

WHY « SO MUCH HATE » ?

To tell the truth, I don't know !… 

Between a lack of attentive listening, ignorance of the consequences (or ... ???) ... There are several possibilities!

Why don't we simply realize an optimized "compression" of the whole work and thus bring the difference between the beginning (low level) and the end (high level) into an amplitude interval easier to listen to in mobility ?

Perhaps because the vast majority of compression solutions tend to "mute/soften" the sound a little and reduce the width of the stereo image (difficult to quantify, but a reality in comparative listening).
