<p>Oy, that's bad. Sound Check is not supposed to implement DRC.
Please Measure the PLR of each version. That would tell us
something to tell Buddy about if it's happening.</p>
<p>I'm not subscribed to Apple Music. It's just one more service I
don't want to pay for. If I sign in, can I download this one album
without beig forced to be a subscriber?<br>

<p class="">you should capture both ways. If you
detect anything other than just a gain shift,
then we should alert Buddy and maybe he can get
that changed.</p>
<p class="">And in fact, if you can give me links
to that choral music I'd like to check it and
measure it</p>

<div class="">I just previewed the first track of “Hodie"
and it has a +9 Sound Check value using iTunes in
Mojave, which takes it to +0.1 dBFS @ 2:54 and sure
enough it clips audibly, so no limiting in this case.</div>
