<p>Hey guys, I came up with that first: album normalization for
everything. I've argued for that from day one.</p>

Hi Eelco and Ian,
<div class=""><br class="">
</div>
<div class="">This is all amazing. Using Album normalization for
everything is something that just never occurred to me, thanks
for out-of-the-box thinking, Eelco!</div>
<div class=""><br class="">
</div>
<div class="">Yes, I've know Buddy Judge pretty well for over 5
years now, we worked together during the “pre-release” stage of
MFiT. I met him in person in California and he has always been
very straight forward with me. I’m so glad to finally read SOME
rationale for why Apple has not turned on Sound Check. </div>
<div class=""><br class="">
</div>
<div class="">I had two questions:</div>
<div class=""><br class="">
</div>
<div class="">1. I agree that all services should use the same
algorithm for normalization.</div>
<div class=""><br class="">
</div>
<div class="">Eelco, I’m not clear about this:</div>
<div class="">VERY often we do a single that is being released <u
class="">before</u> the album is finished. </div>
<div class="">How will the average album level be determined if
there is no album with which to measure when the single is
released?</div>
<div class=""><br class="">
</div>
<div class="">2. Does Sound Check measure highly compressed music
any better than BS1770 (I assume -4)? I’d be surprised if it
did.</div>
<div class=""><br class="">
</div>
<div class="">That is mind-blowing that someone would put 20kHz
tones into the music in order to make it louder. </div>
<div class=""><br class="">
</div>
<div class="">I’m very encouraged by all of this!</div>
<div class=""><br class="">
</div>
<div class="">All my best,</div>
<div class="">Bob L.</div>

<div class="">Yesterday Buddy Judge, senior product manager
at Apple and responsible for iTunes, came to me after my
presentation. We had a beer and then we even went for
dinner together ("all on Tim" :-). Buddy is a cool guy and
a musician (I guess Bob Ludwig knows him well since he is
also the guy behind "Mastered for iTunes"). Buddy told me
a few interesting things that may help us understand why
normalization was not turned on by default yet:<br
class="">
1. The artistic integrity is very important for Apple.
Just like Tidal they do not like that with track
normalization the loudness integrity of an album is
disturbed. Buddy told me it had never come to his mind to
advocate using album normalization even in shuffle mode,
but he found it an interesting concept that he would love
to test.<br class="">
2. Buddy said that if normalization would be turned on by
default, all streaming services should use the same type
of normalization so mastering engineers can anticipate to
it and would not have to make seperate masters for every
different platform (because many will likely still aim for
being the loudest). ITU BS1770 seemed to make most sense
to him, although he knew that compressed music is measured
a little too loud by BS1770. Album normalization with the
loudest track aligned to target level also made most sense
(in my presentation I showed that when normalizing the
_average_ album level (like currently in iTunes), the
loudness of the loud hit tracks would only be known when
the full album is finished - this is a clear no-go for a
mastering engineer).<br class="">
<br class="">
We promised to stay in regular contact the next few months
and all in all this feels _very_ encouraging. <br
class="">
<br class="">
But this brings me to an important note. Pop music
mastering engineers might even be worse than Italian
commercial mix engineers. So if the latter ingest 20 kHz
tones just above the relative gate threshold, to gain 1 or
2 dB of level, this will probably happen to pop masters
too. Florian, it will become even more important to
convince ITU to add the HF low pass filter to K weighting,
so we better make sure that this development is not
delayed too much...<br class="">
<br class="">
Cheers,<br class="">
Eelco<br class="">
