  Thanks, I already used Replaygain. It's better than nothing, but it doesn't solve the difference in dynamics among old and new material which affect our sound level perception. An old recording is often less compressed than a new one, therefore it has many higher and lower peaks, so by simply raising its level we could get to a point in which some of its peaks are higher than the new song, for example triggering the red leds on a vu-meter, but the average level is lower so that we still hear the other recording as louder. It's the average level that matters, that is, dynamics, and sadly there's no way to modify it without re encoding.

    VLC can apply a compressor and other effects at playback time, but that may over-compress the newer recordings that already are loudness-maximized, depending on the settings.
