Not sure if this is old news (nor is it very important), but "target MP3 alteration volume level" option for ReplayGain is broken.

I expected this option to affect the result of replaygain scanning, but it seems to have no effect on that.

foobar2000 is able to modify the loudness of mp3 files (in the same way as mp3gain do).

The question was answered, but I'd just add that with foobar, no "undo" info is written to the tags. (mp3gain writes such info by default)
Personally, I've never had a need to undo the change.

Sorry, but that's NOT the case.

I know, that the quoted post ist a little older, but it still pops up if you do a search.

Both programs foobar and MP3Gain are based on the same method to calculate the volume of a track, but after that the handling, in other words the storing of the calculated values are totally different.
foobar is writing the calculated values in the following tags: "Track gain", "Track peak", "Album gain" and "Album peak" without changing any audio data. Therefore it can simply be resetted by removing the tags from the file.
MP3Gain is changing the so called Global Gain Value in every single frame of the entire track and is indeed changing the audio data. These values are limited to steps of 1.5 dB. To make the change undone if needed, MP3Gain saves the change information within the tags.

In case those tag entries get lost you are not able to make any changes undone. But you could alsways set the target volume to your desired value, just make your best guess what the original volume was before.

Hope this helps to clear things up.

Your statement is incorrect: foobar2000 is able to modify the gain values of MP3 files by selecting the option "Apply {track|album} ReplayGain to file content."

foobar 2000 is NOT able to modify the loudness of mp3 files in the same way as mp3gain do, because if you select the option you named, foobar 2000 is not able to undo these modifications, but mp3gain is able to reset its modification, because its generating an APE Tag within the necessary informations. Of course this is not the same way...
