Floating point is great news. <br>
<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><br>
</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><br>
</div>
<div>I hope to see you all in New York!</div>
<div><br>
</div>
<div>And Bob Katz, best of luck with Irma...</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>
