Hi Folks,

Started looking into getting all my music tagged for replaygain. I have all my music stored as flac.
A trawl of the forums revealed that I can get set up by using foobar2000 to tag all my music which I've started. I have some questions as to how this actually works.

Does it consider the volume levels of every track in the music collection before applying gain values? If so, does this mean every time I rip a new CD I'm going to have to rerun it across the whole collection again? Hope not becaus it seems to be taking ages!

Thanks

Paul

To apply replaygain to the tracks on an album, you only need to scan (all the tracks on) the album, not your entire collection.

No I believe that it calibrates the sound level to a set reference which I thought was normally 89db but the replaygain websites says is 83db.

That means you can simply apply replay gain to the any new music that you have and don't have to rescan your entire collection.

It does take ages because it performs complex calculations on the entire file, but at least it is a one off :)

Have you checked out http://www.replaygain.org/ there is a great section which explains in fairly plain Englsh what it does.

Since you're using Foobar2000, the process is very straightforward. Just load up all the albums you want to process. If they are in a single directory hierarchy, that's trivial: right-click the folder in Windows Explorer and select "Enqueue in Foobar2000". Now select everything in FB2K (Ctrl-A), then right-click to get the pop-up menu and select Replaygain -> Scan selection as multiple albums. This will add both track and album gain tags. What happens is that all of the tracks in each album are analysed, and after the last track in an album is done, it writes the tags to all the files in that album. If you switch on the console log display you'll see what's going on.

As for rescanning the entire library: no that's not required. Just replaygain scan the new CD(s). Also, FB2K has an option to only scan and apply replaygain if the file doesn't already have the tags. If you switch this option on, then even if you tell FB2K to replaygain your entire collection, it'll (very quickly) skip all those that were already done. (Sorry, I'm at work right now and don't recall the exact place where this option is set).

Great - It just had to work sensibly I guess!

Thanks for all the replies.
