Just wondering what "Use peak info to scale down tracks that still clip after applying replaygain" does, exactly. If I do track gain in FB but use album mode to replay, will FB automatically use the peak info from the track gain scan to lower the gain?

The reason I ask is that I have a collection of tracks, all from different sources, so the gains are all different. For this kind of case, it doesn't make sense to use album gain, but I don't want to have to go switching my FB settings every time I run across this selection of tracks.

It will....I track gained some classical mpcs (because some were too soft, and so far I've never seen album gain add positive gain), and Foobar used these replaygain values even when I set it to use album gain.

As for your first question... Replaygain also calculates the peak value of every file you scan, and if insufficient negative gain is added (especially when inputting custom replaygain values, or if some highly uncompressed audio still clips at -11 dB, taking 0 dB as loudest volume before clipping; I got 3 of those files ), I guess the peak value will be equalised to 0 dB, before the audio file is outputted. Something like that .

Thanks for the reply, sld. That's a big relief for me. Now I don't have to mess with FB's replaygain settings when I put my music on.

On another note, I have seen positive replaygain values. Very rare, but at least I know they exist!
