YouTube's new loudness normalizer


It seems YouTube indeed is 'enhancing' everything we are posting lately, so I decided to do a test to see which sound quality will remain untouched as loudness factor. Will not mention the other quality factors here, which are already altered, being compressed from PCM WAV to other formats which aren't lossless at all. But at least, the loudness factor to remain the same!
So I decided to remake the song "Hello Sunshine" feat. GUMI using what I should have used if it was about making a VINYL RECORD.
The results:





As you can see, the wave form show a clear high range of dynamics, clear sound, nothing hits the ceiling of a limiter, or the limits of the max audio range! Surprisingly, YouTube's encoders also aren't touching this sound either, being in the range of normal loudness considered by their encoder to be NORMAL.
My recommendation: since YouTube decided to hit the loudness factor and to crush the quality on the non-dynamic sounds, let's all start using the clever sound creation! Let's maximize the quality by rising the clearness of the recording and to increase the DYNAMICS at the normal or at least at the decent levels. On PCs it will be very obvious, but the mobile phones and other mobile devices are already having a bunch of compressors on their sound cards, but even so, the higher dynamics sound will definitely show up better on those devices too!
In the end, let's listen all to the test I made:
