Replay gain

I have read here on the forum about replay gain and that you first need to create the gain info with foobar2000.
Now I have from all the file’s the repaly gain info and is there is a possibility to scan the database for the replay gain tag? because when I throw away a file now and rescan for new file’s mairlist find the replay gain info but to do it 13,000 times? and enter al ramp tags again

in the properties you can re read file tag and then sometimes comes the replay tag value but not always , and all the file’s are tagt in foobar2000 there where no errors en if you look up the song in de list of foobar there is a replay gain value

Extracting the ReplayGain values from the file tags is part of the general “read file tag” process, so in order to re-read ReplayGain, you will have to re-read the entire file tag (e.g. in the Mass Edit dialog). Not sure if that is desirable in your case because you will lose any changes made in the DB since you imported the files.
