<div>The information in that message about a limiter on iOS

<div>As far as Sound Check versus R128 goes, for me R128 is much
more successful musically, although if Apple switched to album
Normalisation that might improve things.</div>

Floating point is great news. <br>

Do you have any news on Tidal and album norm? <br>
<br>
<br>
Looks like by the time Irma reaches Orlando she will be a
category 2 so hopefully not a catastrophic event for this
region. But I feel very sorry for Miami... looks like it's
going to be a direct hit and the worst story ever to hit
Miami.<br>

Hi MLA friends,

</div>
<div>This news was shared on the PLOUD list. On the one hand
I thought that iOS was already working in this way, but on
the other hand it is very good news that Apple has changed
this!</div>

<div dir="ltr">Dear all,
<div><br>
</div>
<div>I am running Apple's iOS 11 Beta on my phone,
and I discovered that the manufacturer has made
a good step in loudness normalisation
architecture.</div>
<div><br>
</div>
<div>I have understood that previous versions of
the iOS operating system have used fixed point
architecture and therefore it was important to
not exceed peaks before the device volume
control stage. This led to the problem that apps
had to run hot if the user volume control was
low.</div>
<div><br>
</div>
<div>Now in iOS 11 it is possible to run an
overmodulated signal through the dedicated Music
app without any distortion, which means there's
a floating point architecture.</div>
<div><br>
</div>
<div>There's still a limitation of the adjustment
range, and of course the algorithm is still not
ITU BS.1770. It is only possible to adjust a
file within -12 to +12 dB's. But with a floating
point architecture, this is actually not a
problem, because you can adjust very quiet
material to a louder floating point target than
it would have been possible "straight in the
file". The range should still be a little wider
to cover all the material.</div>
<div><br>
</div>
<div>Music app still addresses the peaks by
default, and it is not possible to exceed 0dBFS
with its initial setting but it was possible to
test this by overwriting the audio file iTunes
normalisation metadata which contains the peak
and loudness information.</div>
<div><br>
</div>
<div>Let's hope this is a good step for the
loudness normalisation in other apps too.</div>
<div><br>
</div>
<div>All the best,</div>
<div>Mikko</div>
