The normalisation will not really modify the mix or the dynamics. It just adds some gain so the level is the maximum that the export file format can handle without clipping. In other words, it should sound just the same after you adjust (reduce) the volume. Now if playing back the normalised file results in clipping or distortion, that means that either your sound card can't handle full digital level, or you have too much gain after the soundcard. > Still, this brings a practical question: how to integrate tranquil > pieces in a list, say, as on a CD, without having the listener going to > the volume knob and, while still keeping intact the breathing room of > the soft pieces in comparison of the loudest ones in the same set ? If the CD has both pieces that should be loud and others like yours that are meant to be softer, then you did the right thing. But it all depends on what the listener wants - many will want a constant level regardless of any artistic intentions. Your track has quite a low level, even if it is intended to be soft. Ebumeter says the loudness is -3.7 LU. That's relative to an already low referenc value of -23 dB. Still that's probably OK iff any other tracks it is bundled with are also mixed to a well defined loudness instead of maximum peak level. It's a real shame that Ardour only offers peak normalisation. Peak level has no perceptual meaning at all, there is really no reason why a mix should ever be peak-normalised. All the code required for real loudness normalisation is already there, so it would be trivially simple to offer that as well. Ciao, -- FA A world of exhaustive, reliable metadata would be an utopia. It's also a pipe-dream, founded on self-delusion, nerd hubris and hysterically inflated market opportunities.
