Understanding the Volume Limit on Apple devices (I don't own one)

So far it is clear.

What is not clear:

Does it address the issue of your various recordings have been recorded with different loudnesses relative to each other?

Say, you want to set your volume limit to x dB, both for listening to online stuff and the various stuff you have downloaded, what are best practices to proceed with all your content on your iOS devices to sound on the same volume? I guess there is a (not app, but) computer software for that.

The volume limiter is strictly for limiting the maximum output level from the device. It does not make everything the same loudness. For that, you need the "Sound Check" feature in iTunes, which will add a tag to your music files that your iPod or iPhone understands. It will then boost or cut volume when playing back individual tracks, giving them roughly the same loudness.

For non-Apple devices and applications, Replaygain works similarly.

Even if you equalize the loudness of the tracks you still have to be careful because different headphones have different sensitivity (which varies by up to 30 dB between sensitive in-ears and insensitive, high-impedance headphones).

Apple portable devices are designed to go loud to compensate for quiet recordings, quiet headphones and the use of dsp's such as equalizers.  This is a good thing and makes

for a flexible portable audio player.

However some headsets are very loud to begin with and can result in tectonic levels if the device is turned up all the way by accident.

Inorder for these output levels to be permissible by all government starndards around the world, Apple is required to implement the ability for the user to limit how loud the

sound is at the highest level.  This limiter is located in the "restrictions" menu of the device which can be protected by a password.  This gives a parent the ability to limit

the maximum volume of their child's device to a level the deem to be safe.  It also helps to eliminate startle should the volume slider be accidentally be struck.
