Will I need to do ReplayGain if iTunes has Sound Check?

I've been using ReplayGain (Foobar) to level the loudness of some audio file compilation.

If my daughter has a different compilation, mostly for listening to her iPad, does it even make sense for me to run ReplayGain (using Foobar) first prior to using Sound Check?

Also, should I enable Sound Check on both iTunes (on the pc) and on the iPad? Or will turning Sound Check on iTunes prior to syncing with the iPad do? I know it doesn't take much effort to enable them on both devices but I just wanted to know.

Doing a brief check, seems they both do pretty much the same thing. Like Microsoft, Apple like to do their own thing.

Doesn't sound like Itunes/Apple support ReplayGain info, so you'll have to rescan with Sound Check, and hope the files keep the tags from both.

Thank you.

For Sound Check you have to enable it on iTunes first so that it will add the information into the file/database (it will do the scan immediately). Afterwards I think you can turn it off but the file will retain the information. You can check the volume setting when you go into the "info" of the file on iTunes.

Then when you sync it with your iOS device it will have that information, but you have to enable it on the device also to actually use it. If you leave it off then it won't use it.

So simply put, enable it on both.

Thank you both.

It's just that when I first enabled Sound Check on iTunes on my pc, I don't think it scanned the existing library at that point (or maybe I failed to take notice). I did, however, see the message (on the top center of the screen) that for any other file transfer I made, the song's audio level was checked by iTunes.

Yes, we've enabled Sound Check both on iTunes and the iPad.
